Then world-famous computer scientist Dijkstra once said, (http://
www.cs.virginia.edu/~cs655/readings/ewd498.html) "Besides a
mathematical inclination, an exceptionally good mastery of one's
native tongue is the most vital asset of a competent programmer."

But since the international language of computer science, business and
open source software is English, that exceptionally good mastery had
better apply to English whether or not it is your native tongue. You
are going to find getting the help you need through online forums very
difficult without it. It is hard enough with it:(

And yes, the site http://www.catb.org/esr/faqs/smart-questions.html is
very, VERY good.

[android-developers] Re: Help for Android spiner data binding.

[Indicator Veritatis]

As http://www.catb.org/esr/faqs/smart-questions.html suggests, rather
than make the reader read through your entire code and run it himself
to figure out what the error is, if you tell us the error message and
which line of code it comes from, you are much more likely to get a
helpful answer.

No promises though, since you admit the code below is only 'almost'
complete;)

Also helpful would be to show us what happens when you access the same
data from the same database using the sqlite3 command in adb shell.
Then we would know for sure that your database is sound.

[android-developers] Live Wallpaper Preview/Real Conflict

[HaMMeReD]

I've made a LWP, and it seemingly runs perfectly, but the problem
seems to lie in the fact that when you set the wallpaper, after the
preview has loaded, it gets a out-of-memory.

It seems that since all the engines are in the same VM I don't have
enough memory to start it a second time. How can I tell if the preview
is dead and freed?

I've done what I could to ensure that as much is shared between the
engines as possible, yet still out-of-memory on setting after the
preview is loaded?

Any thoughts would be great.

[android-developers] Re: appbucket: all apps for $9.99 per year, are we just going to watch?

[Indicator Veritatis]

Don't rely on web anonymity for protection. When presented with a
subpoena, bulletin board operators, moderators, ISPs and the like have
to reveal whatever data they have concerning who it is who posted
anonymously. This would be a bad time to be surprised by how much data
that is.

Of course, if you KNOW that the particular method of posting
anonymously that you chose is immune to such data collection, then you
can rely on that. But be sure that what you 'know' really is true.

Then again, one would hope that even in jurisdictions with such nasty
libel laws, they would hesitate to take the case of an obvious pirate.
But that is something I would research carefully, maybe even
consulting with an ABA lawyer, before relying on it.

[android-developers] Webview inside Scroll doesn't resize

[Edwin]

Hi all, I put a webview inside a scroll view according to this
http://www.anddev.org/view-layout-resource-problems-f27/add-imageview-to-bottom-of-webview-t19169.html
.
But I found that if the webview already loaded a long content, and
then load short content again. The webview doesn't resize and the
scroll bar is still here.

for example, load "test" and then
load "test" in the webview will cause this problem.

How can I resize the webview the fit the content.

Re: [android-developers] Please help me with calculating direction from point A to B

Well.. I'm guessing it's to hard or impossible then.. :/

On Sep 17, 2010, at 9:56 PM, Pedro Teixeira wrote:


Hi everyone...

I'm back with the same issue for the last couple of days… I'm trying
to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this line to
point for a specific point. I've been trying dozens of algorithms and
nothing works..
I've finally found one that points me exactlly to the point I want..
BUT it doesn't move if I change the position of the device which is my
objective.. basicly, what I want is that no matter the direction I'm
using my device.. the line always point me to the point
(picLatitude,picLongitude)…

I understood that for the line to move, I can't use static variables…
I need to use the values offered by the onSensorChanged(SensorEvent
event).

This are the data I have available:

event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously

And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):

double dLong = picLongitude - mLongitude;
double y =  (Math.sin(dLong) * Math.cos(picLatitude));
double x =  (Math.cos(mLatitude) * Math.sin(picLatitude) -
Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong));
double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y,
x)));
float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);

myCompass.updateDirection(angleDegrees);

I got this "bearing" formula from this website:
http://www.movable-type.co.uk/scripts/latlong.html


Can someone please help me with this?
I've try adding, subtracting… the azimuth.. I've tried with the
others.. seriously at this point I'm just demoralized..

Thank you in advance

[android-developers] Re: Application-wide resources.. how to achieve?

[Indicator Veritatis]

Dianne Hackborn just did a post recently recommending not to use
Application unless you really, REALLY need to. (My words, not hers).
What criteria she had for "really, really need to" were less clear to
me, but I think it was that the data really need to be global (to the
application), and do not need to be persisted (as SharedPreferences
would do).

[android-developers] Re: SurfaceHolder changed : Stops Video playback

[Indicator Veritatis]

The obvious solution seems to be: instead of letting it play after
onPause(), save your position in the file (MediaPlayer has a
getCurrentPosition method), and pick up from there after you recreate
the SurfaceHolder in onResume(). I don't think the user wants it to
continue playing after onPause() anyway, audio or audio+video.

Or did you try this and were unable to get it to work?

[android-developers] Re: How to install the .apk file into blackberry

[Indicator Veritatis]

You did not read closely enough. I never -said- Android was a JME
platform. Rather, I said that BlackBerry was a JME platform, and that
Android used the Java language, NOT the platform.

And yes, a JME app written for one phone has a good chance of failing
on another JME phone, which is why people say that Sun's promise of
"write once, anywhere" has become (at least for JME) "write once,
debug everywhere";)

[android-developers] decode image

[pramod.deore]

Hi, all I am developing one application in that I want to decode
image, I have one .txt file which contains encoded format of image
(image is encoded using Base64 format). I have Base64 class in that I
have decode(String base64) method which accept String and return byte
array. I have one txt file of size more than 6MB which contains
encoded image now I want to decode that image to .jpg format . I had
tried it but when I open decoded image it is not open.and size is also
very less (18KB and expected size is 5MB)   Here is my code


 public void decodeImage()
{
System.out.println ("Now decoding image");

try
{
image.createNewFile();
 byte[] byteArray = new byte[102400];
 FileInputStream fstream = new 
FileInputStream(imageFile);
 int bytesRead = 0;
 while((bytesRead = fstream.read(byteArray)) != -1)
 {
str = new String(byteArray,0,bytesRead);
byte[] im = Base64.decode(str);
out1 = new FileOutputStream(image);
 try
 {
 out1.write(im);
 out1.flush();
 }
 catch (Exception e)
 {
 e.printStackTrace();
 }
 }


 out1.close();

}
catch (Exception e)
{
e.printStackTrace();
}
}

What is fault? Please help me . Thanks in advance

[android-developers] Re: How much money do you make?

[Alex]

I am very interested in the responses to this thread.

I only have one app on the market, a simple home page widget.  It is
free, and it has been downloaded 13,937 times with an active install
percentage of 47%.

Obviously, I would like to make some money from my apps, but when I
look at paid versions of similar apps to mine, the download numbers
are pitiful.

We are constantly reading about the massive growth of Android and the
10s of millions of devices out there, so why do most apps struggle to
even grab a tiny percentage of that user base?

Re: [android-developers] Please help me with calculating direction from point A to B

[Kostya Vasilyev]

 Pedro,

If I understand you correctly, you are having difficulties with the 
device's orientation.


The bearing angle seems to be computed in the horizontal plane. If you 
wish to adjust for the device's orientation, you need to concatenate it 
with the bearing angle.


Google for "quaternions".

This is a (relatively) simple math technique to work with rotations the 
same way you can work with vectors: add / subtract, interpolate.

Hi everyone...

I'm back with the same issue for the last couple of days… I'm trying
to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this line to
point for a specific point. I've been trying dozens of algorithms and
nothing works..
I've finally found one that points me exactlly to the point I want..
BUT it doesn't move if I change the position of the device which is my
objective.. basicly, what I want is that no matter the direction I'm
using my device.. the line always point me to the point
(picLatitude,picLongitude)…

I understood that for the line to move, I can't use static variables…
I need to use the values offered by the onSensorChanged(SensorEvent
event).

This are the data I have available:

event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously

And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):

double dLong = picLongitude - mLongitude;
double y =  (Math.sin(dLong) * Math.cos(picLatitude));
double x =  (Math.cos(mLatitude) * Math.sin(picLatitude) -
Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong));
double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y,
x)));
float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);

myCompass.updateDirection(angleDegrees);

I got this "bearing" formula from this website:
http://www.movable-type.co.uk/scripts/latlong.html


Can someone please help me with this?
I've try adding, subtracting… the azimuth.. I've tried with the
others.. seriously at this point I'm just demoralized..

Thank you in advance

Yes, this is indeed a curious thing.

Especially given that, compared to the price of a phone + cellular plan 
(outright or per month), the price of a typical Android application ($3 
to $5) is quite insignificant.

[android-developers] What is exactly the X and Y coordinates in method "canvas.rotate"

[jlopeznava...@gmail.com]

Can anybody explain me what is exactly that coordinates? I have search
for information but can't find properly info.
I have some drawables objects wich I need to rotate, I have realized I
need to add a constant value to that coordinates, if not they rotate
wrong.

I use this way:

==
canvas.save();
canvas.rotate(90 * mRotatationType, CTE_ROTATING_X_POINT + coordX,
CTE_ROTATING_Y_POINT + coordY);
canvas.restore;
==

Where:
-mRotatationType: is set to 0, 1, 2, or 3 in order to get a 0, 90,
180, 270º rotation.
-coordX and coordY are the top/left points of my drawable object.
-CTE_ROTATING_X_POINT and CTE_ROTATING_Y_POINT are set to "48" (if not
the drawables move in a different place after rotate). This is the
mistery for me.

[android-developers] Best method to save a array in Bundle?

[jlopeznava...@gmail.com]

I have 2 dimensions array like this:
public myArrayType[][] mObjArray;

I want to save it in the onSaveInstanceState method, since my array
contains lot of elements I dont want to save element by element but
the whole array object, what is the best way?

I tried this but exception is thrown:

-

 public Bundle saveState(Bundle map) {

if (map != null) {
map.putSerializable("objLevel", (Serializable)
mCurrentLevelMatrix);
}

return map;
}

---

I have seen a putParcelableArrayList method but dunno how it works
exactly.

I do not expect a WebView inside a ScrollView will work. They both
know how to scroll, and scrollable things in scrollable things does
not work well in Android. I suggest that you come up with a UI design
that can avoid this requirement.

Switch to using HttpClient and a BasicResponseHandler:

Re: [android-developers] Best method to save a array in Bundle?

[YuviDroid]

I haven't played with this, but if you make your class (myArrayType) implement
the Serializable interface it should work fine. Of course, all the instance
variables of that class must also be Serializable, otherwise you would still
get an exception (probably a NotSerializableException).

Hope it helps,
Yuvi

Re: [android-developers] Webview inside Scroll doesn't resize

[Kwok Chun Wing, Edwin]

I think the first option is not suitable for me since I need the image 
be shown only when it is scrolled to the end.


It maybe good to add some html in the webview content, but I want to 
know how to right such html
, but the image is stored in the drawable, 
how the html can obtain such image?


Thanks for your advice.

[android-developers] Re: How much money do you make?

[Michael A.]

Alex, I think the answer to your question is pretty simple: 99.99% of
the apps users download are the same 100-200 top apps. This is the
case even in the appstore/iTunes - the big difference there, of
course, is that there are much better tools available there to
facilitate browsing and discovery. Actually, I may be giving too much
credit to the Android market, because in practice it does not support
app discovery. I'd almost say that the few successful developers are
successful in spite of the Android ecosystem, rather than because of
it. The large number of apps that blatantly break the Android market
TOS together with the huge number of spam apps (30%, according to
appbrain in March) are all symptoms of an eco-system that is far from
friendly for independent developers.

One reason, I don't like to discuss how much I earn (beyond the
obvious reasons), is that earnings are extremely variable - especially
with ads; for instance, I've seen fluctuations of 300% revenue from
one day to the next, so anything I might write now could be completely
inaccurate in a week. It can also easily comes across as bragging.

I have 2 apps on the market (both free); one pretty much finished
(haven't done anything on it for a while), the other still being
improved upon. The latter is the successful one - it is high enough on
the market that a user might find it if he scrolls down the relevant
category for long enough (most new users still find it through
updates, though). It's currently up to around 90,000 users (it's about
half a year old). No idea what the install base is - I do not trust
Google's numbers at all any more (cf. other discussions here).
According to Flurry, the app currently sees some 10K active sessions a
day.

It is currently making double digits per day in ad revenue, though
still a good distance away from Doug's triple digits. Still, assuming
the growth in active users continue over the next 3-4 months
(possible, though the market gets ever more competitive) and that the
current eCPM is maintained or improved (very uncertain), I think three
digits is possible. A lof of ifs involved, but it is still pretty
amazing to me, as a couple of months ago, the game was not making more
than $2-$3 a day.

I would certainly consider a paid version on the market, if this was
an option at all. Even a 2% conversion rate would probably double the
daily income; more than that (Polyclef has about 5-10% conversion,
from what I can gather) would certainly place the game within reach of
three digit income a day.

Based on my own experiences, I can certainly see how someone could
make a pretty OK living from simply focusing on developing Android
apps, although I don't feel the least bit tempted myself (I've poured
a lot of work into my apps, but it's still been out of my free time).
I still find it inspirational to read stuff like Polyclef's blog,
though.

Regards,

Michael A.

[android-developers] Re: How much money do you make?

[Neilz]

Very interesting read, this blog.

I always assumed that the ratio would be stacked in favour of Ad
revenue, with Paid revenue falling somewhere behind. But for this app,
it's not the case. Perhaps it's because of the app type, being a well
reviewed utility.

I have a free Ad-supported app with well over a million downloads, and
it's bringing in a very nice ad revenue. I never bothered creating a
paid version, as a) my own research suggested not many people would
pay for it, b) There wasn't much I could offer as an extra (except
losing the ads). One of the things that I get as regular feedback is
"It's free!" and I like to keep it that way.

You never know though...maybe it's worth a shot. Hmmm.

Try android.resource://package_name/drawable/name, where:

Re: [android-developers] What is exactly the X and Y coordinates in method "canvas.rotate"

[Kostya Vasilyev]

 The coordinates are the rotation's center point (called the pivot 
point in the docs).


See here for an interactive demo:

http://www.nbilyk.com/pivot-rotate-example

If you set these coordinates to the center of the canvas, you'll get the 
most intuitive result. But other rotations are possible as shown in the 
link above.

I use this way:

Where:

-coordX and coordY are the top/left points of my drawable object.
-CTE_ROTATING_X_POINT and CTE_ROTATING_Y_POINT are set to "48" (if not
the drawables move in a different place after rotate). This is the
mistery for me.

 Neil,

Perhaps you could try using AndroidHttpClient - supposedly, it has some 
tweaks specifically for the https/ssl protocol so works more smoothly.


Since this class derives from Apache's HttpClient, you'd be able to use 
most of your code on the desktop, as well (you seem to imply that you 
also have a desktop application).

That link was very useful to understand how the pivot point works, now
I understand it perfectly.
I was using 48, 48 as pivot and I didn't realized that was the middle
X and middle of my drawable (it sizes 96x96) so that's because it
rotate properly.

Thank you very much.

IntentService already uses a background thread for onHandleIntent().
Hence, do not use AsyncTask -- just execute your code in
onHandleIntent().

Do not use AsyncTask -- just execute your code in onHandleIntent().

Also, you might consider using a WakefulIntentService, or your own

What exactly is the "it" that they are doing?

Running android on top of a bsd-derived kernel?  Sounds plausible if
they are careful to check and honor licensing for or rewrite if
necessary anything kernel mode like binder or ashmem brought over from
linux android.

Doing something unrelated to android?

[android-developers] Re: How much money do you make?

[DanH]

It's hard to compete against free.  I've not installed many phone
apps, but in terms of desktop apps I find that quality/fit is so
variable that I'm reluctant to pay up front for an app (have only done
it on a couple of occasions), and I would imagine the same is true for
phone apps.  I have on a handful of occasions (maybe 25% of those that
give the option) upgraded a free desktop app to paid to gain more
features (and a little bit out of guilt, I suppose).  I don't ever
recall upgrading a "trial period" app -- for some reason they never
seem that valuable to me when the trial period expires.

One problem that phone apps have, I suspect, is that it's difficult/
impossible (depending on the market) to directly provide interfaces to
upgrade to a new version, whether free or paid, while desktop apps can
do it seamlessly.

[android-developers] Re: HttpClient routine works but w/o connection, it times out?

[davemac]

In addition to putting your http calls into a separate thread, you
could also add HttpParams to your HttpGet object to set timeouts, both
for the connection and for the operation. Something like the
following:

HttpParams params = new BasicHttpParams();

HttpConnectionParams.setConnectionTimeout(params, 2000);// 2
seconds
HttpConnectionParams.setSoTimeout(params, 15000); // 15 seconds

httpget.setParams(params);

If a timeout occurs during execute(), you'll get an IOException,
technically a subclass of IOException depending on which timeout
tripped.

Re: [android-developers] Same color specified in xml file and png appear differently?

[Mark Wyszomierski]

I'm not quite sure what's going on - if I specify the color in my layout xml
like so with alpha = FF:

   #ffebebeb

then at least in the layout editor it now matches the color of my png
(created in photoshop, with the same #ebebeb specification). When I run the
app though, the emulator is showing it as a different type of grey. Did I
miss what you meant by alpha channel difference, Mark?

Well, you are halfway there.

For starters, you need the alpha value of your background color to be
the same as the alpha value of your PNG file. You know what the alpha
value of your background color is, because you are setting it. Now,
you need to determine the alpha value that Photoshop used with your
PNG file.

Also, if you choose a non-opaque (i.e., less than FF) alpha, things
get more complicated, as you have to take into account the stuff the
alpha channel is blending from behind the respective widgets.

Re: [android-developers] Same color specified in xml file and png appear differently?

[Mark Wyszomierski]

Yeah I guess that's why I'm confused, the alpha of my png is 100%. So when I
set the background color in the xml file to explicitly have alpha = ff, then
the layout editor shows the two colors matching. It's just that when I run
the app, the emulator (and n1 at least) show the background color (not the
png) as the different grey, same as when I was previously *not* setting the
alpha = ff. To sum it up:

   before:
  background="#ebebeb"
  drawable in photoshop (100% alpha, ebebeb)
  layout editor and emulator show background as a purplish-grey.

   now
  background="#ffebebeb"
  drawable (unchanged from before)
  layout editor shows background now matching my drawable,
  but at runtime it looks like the purplish grey from before.

I'm not modifying the color at runtime (which could explain the difference),
I'll make a separate test app to try and demo it,

Thanks

Perhaps you can use a small PNG drawable for the view where you currently

[android-developers] StateListDrawable and activity-menu-shown state?

[Mark Wyszomierski]

Hi,

I have a linear layout that is focusable, I'd like it to use the same
background drawable as found in listview items:

StateListDrawable sld =
(StateListDrawable)context.getResources().getDrawable(
android.R.drawable.list_selector_background);
linearLayout..setBackgroundDrawable(sld);
linearLayout.setFocusable(true);

The default state of this selector is to be transparent, but I want a
specific background drawable used in an unselected state. It would be
ideal if we could just "override" this one state, and leave everything
else the same:

sld.addState(new int[] { -android.R.attr.state_window_focused },
context.getResources().getDrawable(R.drawable.my_background));

That seems to work - but if I display a menu in the parent activity,
the background reverts to transparent again. When the menu is hidden,
the background comes back to the drawable I had used for the override.
I'm not sure what states I could override to fix the menu-display-
state-issue - but I'm not sure if this is even a proper use of
StateListDrawables. I could just make my own sld to mimic what the one
bundled with android does, but if I make its highlight state orange
for example, it'll look strange on some devices that have changed the
focus color to green for example with listviews (droid eris for
example). It'd be great to keep everything consistent.

Below is the xml def for android.R.drawable.list_selector_background.
If anyone knows what states to change for the menu display, that'd be
great.

Thanks

[Prakash Iyer]

Just my 2c - the freemium model when executed well could be one answer.
Basically the free app version should do enough to not invite removal due to
either "not compelling" or "too irritating". But it should also entice
enough so that the user just bites - again patience is key as not every one
will bite the very first time.

One app that does this well is Tapatalk (I am not associated with them in
any way other than being a happy, paying consumer). Their free version
allows me to read from forums, supply login, read private messages etc. but
then if I want to post/reply/click thru to bigger images etc I must upgrade.
They didn't keep telling me I was a cheapskate just when I tried a premium
feature. Loved it enough to pay up.

More than the platform it is the individual app I think. As an example, the
free virus scan software that Google Pack installs on the desktop is
irritating me to the point I am going to replace it - asks me to upgrade
whenever it can as opposed to when it makes sense.

Re: [android-developers] Re: What's happening to my posts here? Is someone deleting them?

[Prakash Iyer]

I agree - Google hasn't figured out scale yet. After all they deal with what
a few 10's of searches and emails a day...

Some times I wish there would be some one who actually did what Chris is
referring to. Coming back in a few hours to email and finding out the top
posts are
- where are all my posts? well if none of them made it here then this one
wouldn't as well. if this one did then maybe others did as well...
- i am trying to do something that is well documented for a change. i am too
busy to read, so here let me ask the collective wisdom to solve it for me...
- i have screwed up by actually doing something before reading. now let me
find out if any one here can read logcat output because I sure as hell can
only paste it...

Re: [android-developers] Is it possible to rotate screen by program code but not accelerometer sensor?

[Prakash Iyer]

Not sure what you want to do here. Without the accelerometer the system
wouldn't recognize that the screen has rotated. You (the user) can disable
orientation change in the settings but then no app would ever know the
orientation has changed.

Now, the app can trap the orientation change and decide to do nothing about,
or set a timer and ignore successive notifications to overcome sensitivity
etc.

Re: [android-developers] Re: Eclipse not installing Android Application on Emulator

[Prakash Iyer]

try getting logcat output or use adb to install your package on the emulator
and see what's happening. my guess would be the minSDK version is higher
than what is supported on the emulator...

[android-developers] Exception Logging

[Brad Gies]

 This is a bit long winded (sorry, but I need to explain what I'm doing 
before I can ask the question).


Just wondering if I could get a few (hopefully few hundred) opinions on 
this :


I developed an Exception Handler for my first Android app (released the 
first month the market opened), which logs all uncaught exceptions to my 
server, and since then I have gradually refined it and improved. I'm now 
using it in my 4th public Android app and a few private apps, and I find 
it extremely helpful to find bugs that don't happen to me when I'm testing.


One thing I added that is proving to be extremely useful is an 
AlertDialog when the exception occurs asking the user if it is OK to 
contact him/her if I need more information to be able to fix the 
problem, and a box for them to enter their email address if they agree. 
I don't have good numbers for you on the acceptance rate because most of 
my public apps already have the users email address and for the private 
apps the company enforces their compliance (or supplies the emails for 
me to use). BUT... it looks like about 20% of users do enter their email 
address if asked, and that is more than enough to be very useful.


I think I can increase the percentage of users that do supply their 
emails addresses, and that is what my question is about :).  (I will ask 
it soon)


First, It has occurred to me that my Exception Logger might be even more 
successful for me if other developers were also using it because users 
might have seen it before and trust it when they first see it in my 
apps. That obviously would only happen if quite a few developers were 
using it.


Anyway... sorry it's already getting long, and I AM trying to keep it 
from becoming a book. I have repackaged my Exception Logger and will 
release it in the next couple of days for other developers to use (the 
price is the good one - FREE). I will host the thing on my server (FYI 
it's a Cloud based server so we can increase capacity if needed) and any 
developers using it will be able to log in and view the exceptions their 
app has generated, and sort by time/date, user, and other fields.


NOW.. the question: I think the Exception Logger would be more 
successful getting the users to agree to be contacted IF their email 
addresses were kept confidential. Actually, I don't think there is much 
doubt that would be the case. BUT, there is a tradeoff. Obviously, most 
developers would prefer to see the email addresses so they can manage 
the contacts a bit more effectively without using my website to do it, 
BUT if the email addresses are not confidential, fewer users will give 
them.


So here are what I think are the options:

a)keep the email addresses confidential, but developers can send the 
user an email using my website, include both a reply address which goes 
to my website and then forwards the email to the developer, and also the 
developers email address so the user could respond directly to the 
developer if they choose. I'm sure this would have by far the highest 
success rate for getting contact info  but means devs have to use my 
website to send the first email at least.


b)give the user a choice of keeping the email address confidential 
or just giving it to the developer. This should also have a fairly high 
acceptance rate by the user, but complicates the process for them 
because they would actually have to read the instructions to figure out 
how it works, and quite possibly a few users would think they asked for 
their email addresses to be confidential, when they actually checked the 
other option, and would be upset if they found out later. It's also a 
bit more work for me, for maybe very little benefit.


c)Don't bother keeping the email addresses confidential. All my own 
apps work this way, and it is useful, but I'm sure either of the other 
two options would have a better success rate of obtaining the email 
addresses, and therefore would be better for most devs to get 
information about problems in their apps.


I don't try the a) or b) options for myself because obviously I could 
see the email addresses in my log files if I wanted to look, and it 
would be a little deceitful to tell the user their email would be 
confidential in that case, even if I did use them properly ... BUT, I 
can do that for other developers without stretching the truth at all, so 
I think it's worth the effort if other devs want to use it.


So, please let me know what your opinions are.

I'm also hoping to get some idea of how many developers might want to 
use this. I've already done almost all the work, so it will be released 
even if nobody wants to use it. It freaks me out a little to open up my 
server to an unknown amount of use, but I am well setup to increase 
server capacity quickly if needed, and I don't think the cost of doing 
this will be too horrible (I hope). ...



Sincerely,

Brad Gies

Re: [android-developers] Exception Logging

I have thought along similar lines. I think it should just be option a.
Don't confuse the user with options. In fact don't even allow user to reply
back directly.

and would be upset if they found out later. It's also a bit more work for
me, for maybe very little benefit.

c)Don't bother keeping the email addresses confidential. All my own apps
work this way, and it is useful, but I'm sure either of the other two
options would have a better success rate of obtaining the email addresses,
and therefore would be better for most devs to get information about
problems in their apps.

I don't try the a) or b) options for myself because obviously I could see
the email addresses in my log files if I wanted to look, and it would be a
little deceitful to tell the user their email would be confidential in that
case, even if I did use them properly ... BUT, I can do that for other
developers without stretching the truth at all, so I think it's worth the
effort if other devs want to use it.

So, please let me know what your opinions are.

I'm also hoping to get some idea of how many developers might want to use
this. I've already done almost all the work, so it will be released even if
nobody wants to use it. It freaks me out a little to open up my server to an

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[Peter Sinnott]

Received this update this morning :

Hello,

We'd like to give you an update on this issue. We've previously stated
that some application updates are incorrectly being counted as pure
uninstalls rather than updates, causing the active installs metric to
drop. We have now identified the root cause, and are working on a fix
that we hope to release next week. However, due to the nature of the
interaction between the Market client and our reporting
infrastructure, it may take up to several weeks for your metrics in
the Developer Console to return to normal. Again, we apologize for any
inconvenience, and will keep you posted on our progress.

Thank you for your continued patience.

[android-developers] Re: Android Market Licensing Service

[gcstang]

Are there any examples of how you implemented it that you're willing
to share?

Even psuedocode would be helpful as an example:

Copied java files 1,2,3 into my project as a pkg
Implemented methods A,B,C
Added X of LVL to onCreate of my main point of access on the
application and did X,Y,Z etc...
if return of G fails I did D to exit my application

Or do you have anything you used online that could take you through it
step by step, the blog post is a bit over whelming to someone just
starting and since you have successfully implemented it I think it
would be of great help to the community and myself to know the proper
way to implement the procedure you used.

If you can't I understand but it would be helpful if you could.

Thank you,

[android-developers] Re: How much money do you make?

[Michael A.]

Keep in mind that there is a huge gap between the price to upgrade a
desktop app and a phone app. The usual price range ($1-5) is generally
so small that under normal circumstances, you should see good
conversion rates.

The problem is not that phone apps are difficult to upgrade to a new
version - the problem is that the Android market does not provide the
toolset to allow us to provide smooth in-app purchases and that one
will break the terms of service if one implements it oneself. But this
griping is nothing new, of course.

Re: [android-developers] Exception Logging

I believe option A is the best.

One thing you might consider as a premium option for developers is reporting
showing which crashes are more prevalent than others. I know Microsoft does

[android-developers] Re: Exception Logging

[DanH]

First off, you are to be commended for putting this much effort into
diagnostics.  Even the big players are just catching onto this (as
witnessed by the fact that there's no facility for this built into the
phone).  "Real time" diagnostics are much friendlier for the user than
saying "Please reproduce with logging turned on" or whatever, and
generally the information you obtain is more comprehensive and helpful
(since you're more apt to see several instances of essentially the
same bug, but with slightly different symptoms).

There is a slight danger that the paranoid among users will believe
that you're secretly collecting data on them.  It's probably better to
somehow obtain their permission to send the failure report to you, vs
doing it silently and unconditionally.  Asking them at the same time
if they want to provide an email address is good, though.

In terms of options, I'd say "KISS" -- keep it simple.  Unless the
facility is going to be picked up by a "trusted authority" (say,
Google), just have email address be reported back to the developer.
Promise, of course, that the email address will be kept private (and
make any users of your facilities aware that they're making this
promise) but don't bother with the complex forwarding service -- users
are no more apt to trust it than they are to trust the individual
developers, and in fact they're probably more likely to be confused by
the options and not agree at all.

There's a way, using one of the tools shipped with the emulator, to
determine what color is actually being displayed.  (The tool, which
I've never used, is described in "Pro Android 2" -- don't remember the
name.)  Probably some 3rd party tools can be used for this as well.

Please do *not* use Serializable.  It is really inefficient.

If you want to implement custom marshalling/unmarshalling, implement

efficient.

Use OpenGL ES.

Seriously, you generally can't just accelerate one function and nothing
else.  What you will end up with is the worst of both worlds, as you take
the hit of switching between hardware and software rendering all the time.

If you just want to draw bitmaps to the screen, this can certainly be
accomplished with Open GL ES, and you don't need to rely on the platform to
provide you with essentially helper APIs to make it easier to do that
particular special case.  You can ask anyone here to write such a thing for
you.  Waiting for the platform to provide it is a really bad option because
you don't know when it will be available (we don't really, either), and even
once it does become available you can't really take advantage of it until it
is available on the majority of the devices.

There are so many things people can do without relying on the platform to
give it to them in a nice little bundle.

Use OpenGL ES.
As I stated, using OpenGL ES requires extra code.  You to manage

Activity life cycle this is even more of an issue than other platforms.  
This isn't trivial.  It also exposes you to driver bugs/oddities.


Seriously, you generally can't just accelerate one function and 
nothing else.  What you will end up with is the worst of both worlds, 
as you take the hit of switching between hardware and software 
rendering all the time.
You can actually.  I don't think it's being suggested that you use the 
OpenGL driver to implement a basic bitblt.  Its being suggested that the 
Android OS supports the ability for hardware to accelerate the bitblt.  
Maybe it already does, I don't know.


If you just want to draw bitmaps to the screen, this can certainly be 
accomplished with Open GL ES, and you don't need to rely on the 
platform to provide you with essentially helper APIs to make it easier 
to do that particular special case.  You can ask anyone here to write 
such a thing for you.  Waiting for the platform to provide it is a 
really bad option because you don't know when it will be available (we 
don't really, either), and even once it does become available you 
can't really take advantage of it until it is available on the 
majority of the devices.


There are so many things people can do without relying on the platform 
to give it to them in a nice little bundle.
I don't think anyone is waiting.  I believe it was just a 
request/suggestion.

Re: [android-developers] Exception Logging

[Brad Gies]

If enough other devs do use it, I would put some effort into producing 
reports to make it more useful, but one option that I will do 
immediately is to put a button on the form listing your last ?? 
exceptions to download it in a comma delimited format so you can import 
it into a spreadsheet and do anything you want with it.


The only paid option I am even considering is putting an optional Pay 
Pal donate button on the web page the devs use to view the logged 
exceptions. I'd be happy if that even covered the additional server 
expenses.


I should also mention that devs will (soon) have the choice to send the 
exceptions to their own server if they prefer (the option is already in 
the code), but they will have to agree to some very specific provisions 
not to spam users before using it. When I have time to figure out the 
licensing, and set it up, I will put the code up on one of the open 
source sites so that other people can improve it.


Sincerely,

Brad Gies

 This is a bit long winded (sorry, but I need to explain what I'm
doing before I can ask the question).

Just wondering if I could get a few (hopefully few hundred)
opinions on this :

I developed an Exception Handler for my first Android app
(released the first month the market opened), which logs all
uncaught exceptions to my server, and since then I have gradually
refined it and improved. I'm now using it in my 4th public
Android app and a few private apps, and I find it extremely
helpful to find bugs that don't happen to me when I'm testing.

One thing I added that is proving to be extremely useful is an
AlertDialog when the exception occurs asking the user if it is OK
to contact him/her if I need more information to be able to fix
the problem, and a box for them to enter their email address if
they agree. I don't have good numbers for you on the acceptance
rate because most of my public apps already have the users email
address and for the private apps the company enforces their
compliance (or supplies the emails for me to use). BUT... it
looks like about 20% of users do enter their email address if
asked, and that is more than enough to be very useful.

I think I can increase the percentage of users that do supply
their emails addresses, and that is what my question is about :).
 (I will ask it soon)

First, It has occurred to me that my Exception Logger might be
even more successful for me if other developers were also using
it because users might have seen it before and trust it when they
first see it in my apps. That obviously would only happen if
quite a few developers were using it.

Anyway... sorry it's already getting long, and I AM trying to
keep it from becoming a book. I have repackaged my Exception
Logger and will release it in the next couple of days for other
developers to use (the price is the good one - FREE). I will host
the thing on my server (FYI it's a Cloud based server so we can
increase capacity if needed) and any developers using it will be
able to log in and view the exceptions their app has generated,
and sort by time/date, user, and other fields.

NOW.. the question: I think the Exception Logger would be more
successful getting the users to agree to be contacted IF their
email addresses were kept confidential. Actually, I don't think
there is much doubt that would be the case. BUT, there is a
tradeoff. Obviously, most developers would prefer to see the
email addresses so they can manage the contacts a bit more

That's crazy. I'm really curios why they are not able to deliver reliable
metrics. First issue of such a nature occurred four or five months ago and
still not fixed.

What is so difficult on this metric? I always thought that Google employs
first class brains, best in the industry. They are able to do a lot of
magics in other products so why they are not able to sum a few numbers? What
is the architecture that makes the trouble?

Re: [android-developers] Re: Exception Logging

[Brad Gies]

It's probably better to
somehow obtain their permission to send the failure report to you, vs
doing it silently and unconditionally.  Asking them at the same time
if they want to provide an email address is good, though.


Just so you know... how it works now is that the exception is logged 
immediately without the email address the first time an exception 
occurs. The server returns the id number of the exception, and THEN the 
dialog pops up and asks if they would mind supplying an email address. 
The user has the choice of supplying the email address and choosing "Yes 
Always send it", "Send it this time" (in which case they will be asked 
again on the next exception, but their email address is kept so they 
never need to enter it again, or the third option is "No, and don't ask 
again" in which case they will never see the dialog again for the life 
of the app.


If they answer "Yes, always" then they will never see the dialog again 
either, and the email address is just included in the original post when 
it's sent.


Note that it is programmed this way because there are occasions when an 
exception occurs in the onCreate of your activity and the user interface 
is unstable, so even if I try to pop up the dialog then, the user won't 
see it. When the exception is logged, I use a couple of Preferences to 
keep track of what's sent, and all info needed for the dialog box, and 
when the Class is created, I check to see if an Exception occurred and 
the dialog will popup then (on the next activity created) OR I also have 
a function that can be called in the onResume event of each activity to 
check to see if a dialog is needed. If you use that function then the 
user will get the dialog box almost immediately after the exception 
occurs even if they use the back button to get out of the activity that 
caused the problem (the only time this doesn't work is if the exception 
happens on the onCreate of the main entry activity), and I would hope 
most devs have that covered already. The Exception would still be 
logged, but the user would never see a dialog box because the user 
interface would never be stable.


There is also a "Let me see what's sent" button and a Help/Info button 
to give some information on what it is, and what it's doing.


>users are no more apt to trust it than they are to trust the 
individual developers


That's a good point, and certainly true right now. I would hope if the 
Exception Logger is used by enough devs though that users would see it 
and learn to trust it. BUT... if the user clicks on the Help/Info button 
I already have the statement that the dev has agreed NOT to spam them, 
and maybe that is enough for option c) to be a good option. It's 
certainly a lot less website work for me because I already have all of 
that code working for myself... I'm just in the process of making it 
multi-dev friendly :).


I do use option c) myself, and it works well I just have it in my 
mind that the other options would be even more effective...but, I'm not 
positive and that's why I'm asking for other opinions. The unstated part 
of the question is what would other devs find most acceptable?

Actually, I am very impressed with the response, and I hope you thanked

kind of stuff :).


It's also a bit of relieve to me. I released a Beta app about 3 weeks 
ago, and several updates since then fixing problems, and the quoted 
install percentage was a bit disconcerting to me :). BUT... from what it 
sounds like my numbers are not going to be nearly as bad as they look 
right now. I'm guessing that the short turnaround for updates in the 
Beta app was really contributing to the bug in the numbers :).

Probably not. It's not that it's a hard problem, it's probably more that
it's not "interesting". Google seems to have a philosophy of "tinkering"
with stuff, getting things to a point where they kinda work, but have issues
- then they get bored and move on to the next thing and can't be bothered
with fixing the lingering problems.

Just guessing, but:
1 - Clearly the Market is not the most elegant mechanism for discovering
apps, so that's probably issue #1 right there

2 - Competition - how many task killer, tip calculator, ToDo, or file
manager apps are there? Given problem #1, how do you stand out amongst your
competitors? How do you convince people to pay for you app when others are
free? I've seen $0.99 Flashlight apps and just laugh. C'mon, seriously?

3 - The system is skewed to the "big guys". The only apps I ever see
"featured" are those by big name companies (including Google themselves)
that steal all the attention and really don't need the promotional help to
begin with.

4 - As a user, one reason I hesitate to buy an app is the lingering question
- "is there something better out there now or will there be soon?" Yes, it's
only $1 - $5, but it's still a "commitment" - once you purchase that app
it's yours for life and there's no getting rid of it (on your current
account anyway) so it better be all you hoped for.

It probably is. I've seen many, many user posts on apps requesting an
ad-free paid version. There are quite a few people that are willing to pay
to remove the adds and / or support the developer. Yes, these people often
seem like myths, but they do exist. You really don't have much to lose and a

Only if you're not offering much more, if anything, above what the free
competition is offering. If your app has some killer features not found
anywhere else that people really want, they'll pay for it.

This is what I do and I do think it works quite well. I get way more
positives on the free version then negatives for being limited. And it means
a huge base of potential new buyers.

Hm currently featured on my phone...

"Kids Shape Puzzle" by anahoret
"ESPN Fantasy Footbal" by ESPN Inc
"Glyder 2" by Glu Mobile
"Deadly Chambers" by Battery Powered Games
"Shanghai Travel Guide" by Urban, Inc
"Radio Ball 3D" by Awesome Software
"Kaplan GRE Exam Vocabulary" by gWhiz Mobile
"On the Go" by Five Pumpkins
"Miami Dolphins" by Mobile Roadie
"Sporting News Pro Football" by The Zumobi Network
"Tumblr" by Tumblr
"Tank Recon 3D" by Lone Dwarf Games Inc
"Amtalee" by frostream
"RD3 - Groovebox" by mikrosonic
"Taylor Swift" by Mobile Roadie

Granted, most of those companies I've not really heard of, so I can't say
for sure whether they are "big guys," but it seems reasonably balanced to
me.

And not a Google app in sight. ;)

I tend to agree with Dianne.  I've seen a plethora of "big name" apps as
well as unknowns show up.  I think the real issue is that all of us who have
apps in the Market feel that our apps are the best of the best and should be
featured.  Any time we see a "big name" app on the Market we immediately
think "Well, there you go!  Google is catering to those with $$$."  Any time
we see unknown, indie apps featured we immediately think "What the heck!
 That app is no where as good as mine!!  How did it get featured and mine
didn't?"  So, those in charge (or the algorithm in charge) of what apps get
featured are pretty much damned if you do, damned if you don't.  None of us
will be completely happy until OUR app has been featured.  I have personally
gone through this whole thought process and have come out feeling that I
should just be happy for those apps that do get featured and work my ass off
to try to write an application that could be worthy of one of the featured
slots.

[android-developers] Re: Why aren't the 2D graphics API & UI toolkit hardware accelerated?

[Robert Green]

Bah, 2D in OpenGL really isn't that hard and there's not that much
extra code.  If someone were to just write a simple spriterenderer
class that takes a set of bitmaps and lets you draw them wherever you
want by index then improve it to handle an atlas of images for faster
drawing and you've got 90% of most 2D game rendering code done right
there, all in under a couple hundred or so lines.

The lifecycle isn't that bad - all you ever have to do is reload vram-
stored stuff like textures and VBOs, which I just have a method called
vInit() that does that for any given renderer in the game, and when
the gl context has changed, my main renderer just calls vInit() on all
the subrenderers and all is back into the context and ready.  I think
that took me all of a few hours to get working correctly.
