[android-developers] Re: Piracy Breakdown by Country

[Peter Webb]

I am also an Australian software developer.

I can state with absolute certainty that these figures are absolute
bullshit. 92% of apps running in Australia are not pirated. It is
absolutely ridiculous.

Anecdotally, as a developer I have sought our everybody I know with an
Android phone, maybe half a dozen techies and half a dozen "normal"
people. None of them are even aware of a pirate market in paid Android
apps. The chances of 12 people in a row being in  that 8% -
impossible.

More generally, my app is a live wallpaper. Here is an interesting
stat. My uninstall rate dropped by 20% when I included instructions
for how to run a live wallpaper. At least 20% of android market users
appear unfamiliar with how to run a Live Wallpaper. Yet the statistics
presented imply that 92% of Australians not only know how to install
pirate apps, but also do so. Sound plausible to you?

Australians are no more likely to pirate software than people in any
other developed country. 92% of Australian android phone users
obviously don't pirate android software. For that matter, 54% of
Austrians don't pirate software either, but whatever fraction it is
(I'm guessing a couple of percent at most), Australians and Austrians
aren't going to be that different.

The figures are clearly and obviously wrong. The most basic common
sense should tell you that.

[android-developers] Content-Encoding: gzip,deflate

[Arpit]

Hi All,

I am using the Apache HttpClient and added the header "Accept-
Encoding" and "gzip,deflate". But when I check the header of the
response I always get the Content-Encoding header as empty.

In the header array of the response I can see that "Content-Type:
application/xml; charset=utf-8" as one of the value.

My questions are:

a) Is there a way to check whether a server support gzip content
encoding?
b) If no, how can I find out from Apache HttpClient whether the
content received is in gzip content encoding?

Please help.

Thanks & Regards,
Arpit.

[William Ferguson]

Thanks for posting the psuedo code.
>From the symptoms, the code you posted and the assumption that this
section of code is multi-threaded, it looks like a race condition.

public StaticClass {
 private static Manager manager = new Manager();
 public static Manager getManager() { return manager; }

If 2 Threads simultaneously access the above its possible that the 2nd
will receive a partially configured instance of Manager.
It's one of the reasons I avoid statics like the plague.

Try changing it to:

public StaticClass {
 private static Manager manager = new Manager();
 public static synchronized Manager getManager() { return manager; }
}

Common sense is often a pretty unreliable metric.

Clearly stats based on a single app should not be generalised too much
especially (as gosh mentioned earlier) when the numbers involved are
fairly small.

Here's one theory: Pirate sites have far less apps than the Android
Market and so the apps that are there are far more discoverable. Users
are downloading them out of curiosity and would never have bought them
even if the pirate sites didn't exist. There could be just a few users
downloading a whole load of pirate copies and so skewing the results.
Here's a wild guess: most pirated downloads are discovered directly on
the pirate site (as opposed to users discovering the app on the Market
and then searching for a pirate copy).

Maybe the analytics show those users are regularly using the apps?
This doesn't mean they would have been prepared to fork out cash. For
many users, many apps are nice to have but not good enough to pay for.
Or maybe they simply can't pay for it.

Imagine this for every 10,000 android users in Australia:

8 buy your app
92 download a pirate copy

So it would only take at least 1% of users to actively use pirate
sites to make these numbers work. I'd expect the number to be more
like 10% (another wild guess) which would mean about 10% of those
users thought your app was at least "good enough to try".

The eclipse will also truncate your strings at some point or the
other. I would recommend to just look at the response codes and assume
that you are actually getting the whole long response. Or may be you
can write the response string to a file and check that.

Why would you want to do that? May be you can have a static class and

If data are dynamic or will be changed/updated, client server model is
suitable for your app.Store the data on server than create an interface (rpc

[android-developers] Re: ADT causing CDT to build all C projects on Android app launch??

[Jason]

Hi,

I am one of the elusive few running this exact setup, and I too have
been a bit annoyed by this "feature".

I did just find this:

Window->Preferences->C/C++

There is a checkbox option entitled:

"Build configurations only when there are Eclipse resource changes
within the project and its references"

I tried checking this at it seemed to eliminate these extra builds.

I also tried making a small change to a C++ source file in my project
and it picked up the change when I ran the app.. so seems to work.

Maybe I didn't explain correctly:
If I need to react to some location change for example, and notify the
user, I can't use _just_ an async thread. I need to to all the logic
in a service and throw for example a notification plus a broadcast
that will update the ui if it is on top.
What I was asking is: if I need to perform more than one task in
background (I mean when the phone screen is off, or when the user is
reading the times website while sitting on the toilet), does it make
any sense to create more than one service? Or should I just create one
service that performs many task like listening on the network as well
as being notified of position changes?

[android-developers] Re: Optimizing list view scroll

[Ed]

IMHO having a worker process is definitely worth the effort. It is a
little daunting at first but once you get your head around it it's
great fun to work on.

If you write your image loader worker process in a well structured way
then you will be able to reuse it from project to project. One day
mine might reach a state where I'm happy to release it but I would
want to use it on a few more projects first to ensure it's generic
enough. Plus if I just gave you the code you wouldn't learn anything
and you'd miss out on the feeling of success when it finally works at
3 o'clock in the morning.

I suggest you read this short thread where I commented on
SoftReference: 
http://groups.google.com/group/android-developers/browse_thread/thread/614281daa12a3fd8

I would also suggest watching:
http://www.youtube.com/watch?v=N6YdwzAvwOA
http://www.youtube.com/watch?v=wDBM6wVEO70

Once you've done all that come up with a plan for handling a queue of
requests (I used a PriorityQueue so I can fast track important
images), caching images, returning the images to the caller...etc...
Lots of fun to be had.

[android-developers] Google Maps: Let the user choose a location

[Dirk Vranckaert]

Hey all,

I've been working on an application lately that is using GMaps to
display a location that is stored in the devices database. However
when no location is available (no GPS signal is available) the user
can go through an edit wizard and at a certain point he can add a
location himself. I already have to code to display the stored
location, but is it possible to write something so the user get's to
see a map and when he clicks/touches on a certain area a map pointer
appears and the location is stored.
Is that possible in any way? Is there any good online documentation
available? I searched through this group and on Google but couldn't
find anything usefull.

Kind regards,

Dirk

[android-developers] User photo + latitude-like marker in Custom View

[Joao Luis]

Hi there.

I'm trying to add a marker to a custom view, where I want to show a
given picture --- pretty much like what is shown in latitude.

However, even though I've been working with the Android SDK for a
while, I have absolutely no idea how to do this.

Anyone care to give a hand? Would be really appreciated :-)

Thanks.

[android-developers] Re: How to connect android to Google App Engine

[JP]

I am using GAE/Java to be able to get the code off of GAE if I have to
or want to, and for file uploads, multipart POST, which is basically
the "standard" way of uploading files to Servlet based web servers (at
least AFAIK). There isn't anything "out of the box" that I am aware
of. As you found, there's tons of code fragments in the Interwebs if
you search for terms like "multipart POST" or "HTTPClient". Some
assembly required, which, from where you are at, should take you a
couple of weeks FTE to build and integrate this in your Android app.

[android-developers] Re: Piracy Breakdown by Country

[gosh]

Looking at your numbers again, your 'total installs' for Australia
seem way out-of-whack with the rest of the countries listed, i.e.:

* Take the UK versus Australia figures, your total installs are: UK=
335, Australia=321
* There are about 60 million people in the UK, and only 22 million in
Australia. Both countries speak a form of English as their primary
language, discounting the disproportionate uptake as a UI issue in
your app.
* Google has allowed app sales and app purchases in both the UK and
the US before all other countries globally (Feb 2009). It has allowed
'purchases' in Australia only since Oct'2009, and still doesn't allow
'sales' today.
* Google has had multiple Android developer/code/lab-days in the UK
(i.e. platform evangelism and market building momentum), while the
closest they ever got to Australia with one was Singapore (which is
not very close)… i.e. Google is Australia-averse. In fact, southern
hemisphere averse. For a company that sells globes and maps, it
doesn't seem to be able to peer over its own equators. Its much more
likely that Google will allow app sales from Afghanistan before they
do so in Australia. Android numbers in Australia reflect that Google
apathy.
* Google and the Android-brand have been totally 'unfocused'/blurred
wrt Australia as a market … the only place you see 'Google' in
Australia, is in a browser window. If you phone them, you don't get
past the front-desk staff. If you email them, nothing comes back. If
your write to them, nothing gets returned. It all disappears into a
big white rectangle. It reminds me of the public service in the 1980s,
before office PC productivity. They process all their accounting/sales
data and dollars from Australia through their Ireland office… while
its true that the Australian population was once 75% Irish, that was a
long time ago (in the early 1800s).
* Telstra, the major Australian telco (previously, a government-owned
monopoly, still with nation-wide mobile coverage), only started
selling an Android phone in April 2010 - just a few months ago.
Vodafone Aust. Ltd. has sold one for a while longer - but they are a
much much smaller company, with much less coverage nationally, and
they only sell it via high-end phone plans.
* I'm yet to meet (or even see) a person on the street (outside the IT
world) that actually has an Android phone.

In summary, both your published piracy rate for Australia, and also
your actual 'total number of installs' for Australia, are 'far from
representative' IMHO. I suggest to you that there is something very
odd going on there with your app installs (supposedly) coming from
Australia?

Cheers
Steve

[android-developers] Re: Market:// links in WebView

[Maps.Huge.Info (Maps API Guru)]

What you'll need to do is create a link from your webview into your
app by using a JavaScript command. Inside your app you create an
intent that opens the market app:

JavaScript:

// Launch Market App... (appid is package name)

function launchMarket( appId ) {
  webViewClass.launchMarket( appId ) ;
}

Java:

public void launchMarket(String appId) {
 Intent intent = new Intent(Intent.ACTION_VIEW);
 intent.setData(Uri.parse("market://details?id=" + appId));
  startActivity(intent);
  finish() ;
 }

You'll also need the requisite code to allow all this to happen, I
assume you know how to do that already. If not, Mark Murphy has an
excellent book that details all this out.

[android-developers] Re: Is there a way to request permissions from a user as you need them?

[Zsolt Vasvari]

Let me try this from an end-user perspective.  Obviously, the whole
permission feature was designed by a developer and, IMO, it's not a
very good system in a usuability sense.

As an end user, I only care one and ONLY one permission:  INTERNET.  I
only look for that one permission and the rest is just noise and might
as well not even be shown.  Why?  Because I know as long as the app
has no way of getting my personal info off my phone, I am good, as far
as I am concerned, the app can read all my passwords and credit card
info it wants, if it cannot do much with it anyhow.

That said, the way the Internet permission is implemented is poor and
doesn't really tell you anything useful on which I can make my
decision on.  Currently, if I see "Internet" and need to scan the
other permissions as to what else the app can do and send out to
whomever.

What I would like to see is the Internet permission broken up into:

- Full unrestrictued internet access:  This is fine for a replacement
browser, but if anything else requests it, I probably wouldn't install
that app.
- Local network access only (for printing or network management apps.)
- An spelt out protocol/domain list that the app declares it wants to
have access to and nothing else be allowed.  This should be the most
appropriate for the majority of the apps.

No, you get a single payment every work day.  If you don't like that
schedule, because who wouldn't like 22 small deposits a month, you are
out of luck.

[android-developers] Setting focus programatically in ExpandableListView

[OldSkoolMark]

I have subclassed ExpandableListActivity to create an activity that
presents a simple tree view of the 'world at large' and allows the
user to select one for further use by the app. I am having trouble
setting focus programatically. One thing that baffles me is that I can
use the D-pad to set focus on any of the child or group items in my
ExpandableListView, but inside my onChildClick() callback,
isFocusable() returns false. If I can set focus with the D-pad, how
can isFocusable() return false?

My goal is to avoid having the user have to touch individual
ExpandableListView entries to select them and to provide a couple of
buttons to move the focus up and down inside the list. I  want
selection to be easy for  folks with no D-pad or with a phone that
only presents the D-pad when in landscape mode (e.g. Droid) .

Is there some way I can programatically inject D-pad key clicks into
my app input event stream?

[jgclifton]

Thanks for the response! The other problem I have with this is I'm
showing ads with admob but within the webview rather than using the
android native code (theres a good reason for this) but would this
sort of code be scaleable to work with admob too? I'm not very
familiar with JavaScript.

[android-developers] Re: Market:// links in WebView

[Maps.Huge.Info (Maps API Guru)]

It would depend on the code admob uses. If the point of your question
is because of admob, then you may be able to figure out their call to
start the market and wrap that in a function that starts the intent
within your app. There may be other ways as well. The example I used
was how I do it.

[android-developers] Re: App breaks for some users after they update from the Market

[Zsolt Vasvari]

I would bet any money that this is very clearly going to be a race
condition somewhere.  Your code using a static Map and the user
symptoms are a dead giveaway.

I think the install/reinstall and clearing the user data are red
herrings.  The app might work again for the user if they just ran it
again.

Re: [android-developers] How to connect android to Google App Engine

[Tom Gibara]

I've just published an updated to my Betan application for sharing beta
copies of Android apps. It now includes a server-side app that I implemented
using GAE so that other developers can take advantage of it.

Do I use REST or simple HTTP post/get?


These aren't really in opposition. I would generally recommend REST on
several grounds, in part because it encodes what is being read/modified
within the URL, which is where that information is best recorded. If your
server-side API is not public then it isn't something I would get too
hung-up on it since it isn't necessarily architecturally significant - you
can evolve it easily.

Do I use JSON or XML?


I personally shy away from either for my Android applications. For mobile
applications, you're looking for two characteristics in my opinion:
compactness of representation and speed of parsing. If you're dealing with
very complex or very general data, or if it needs to be consumed by other
services (say AJAX) then either of these will be well suited, but often you
can be very specific within an Android application and a custom mode of
serialization can provide many benefits.

One grudge I have against JSON is that it encourages developers to tie their
serialization directly to their object model. This is very convenient in
your early iterations of a project. But when you need to evolve your
server-side domain objects maintaining compatibility with older versions of
your application can get sticky.

Do I use java or Python.


I think Python is very well suited to GAE. I use Java because it allows me
to maintain a separate 'model' jar containing the domain objects for my
application that I can reuse in both the Android application and on the
server. This is a great convenience.

Even though I have plenty of experience with both, I shy away from JDO and
JPA for GAE, and use the 'native' datastore API, I simply find it much more
convenient; I don't have to think my way through all the partial
abstractions.

Can anyone point me at a usable system for connecting my Android to the GAE?


I think at this stage, it's still a case of writing the connecting code
oneself. But you're communicating simple data, the good news is that it's
not really much work (in my experience).

Tom.

[android-developers] Re: Piracy Breakdown by Country

[Sam]

Let me give you a scenario that i really DOUBT is happening:

1) Users have Screebl lite installed and then decide they really like
it.
2) They then decide to upgrade and get Screebl Pro.
3) Rather than just pick it up off the market (easy) - they scour the
internet looking for it to save a few dollars...

This seems too far fetched for me. Yes for techies this may be "easy"
but for average Joe finding an app and installing it is not easy!

More likely the high piracy rate is due to it being featured on pirate
websites in "bundled packs". In that case you are not losing these
sales, these are sales that were never going to happen.

Just my opinion.

regards

Sam

Re: [android-developers] Google Maps: Let the user choose a location

[Brad Gies]

I assume you are using the "My Location" feature of Maps. Are you also 
attempting to use the network location if you don't have GPS? I find it 
works quite often. I use the code below in my OnCreate MapActivity and 
it doesn't fail very often.


lm = (LocationManager) 
getSystemService(Context.LOCATION_SERVICE);

if (lm != null)
{
Location loc = lm.getLastKnownLocation("gps");
if (loc == null)
loc = lm.getLastKnownLocation("network");

BUT, to just answer you question, you can use the "onTap" event of your 
overlay, determine your Lat/Lons and then use the Geocoder to get your 
address information. Really what you are doing is no different than the 
hundreds of Overlay examples you will find.

when no location is available (no GPS signal is available) the user

appears and the location is stored.
Is that possible in any way? Is there any good online documentation

[nation-x]

I am completely surprised at some of the responses here... but I am
not at all surprised with your results. I have been selling software
for over 10 years before I started developing Android apps and my
experience has been that the US always represents the highest amount
of piracy. Your "culture of piracy" label is absolutely deserved. The
sense of entitlement that people here have always amazes me and
that spans everyone from developers to consumers. They want everything
for free and everything done for them... Piracy aside, after releasing
free applications on the Android market and seeing the absolute
stupidity of the majority of comments and that same sense of
entitlement that I alluded to... I stopped releasing free apps... I
wrote my own anti-piracy measures (note how Astro does it with
expiring updates...) and I ignore stupid comments from users and
fellow developers.

You can also use this so that C is on the top instead of B so when you
click back it will go to A if you launch C from B :

On your Intent set it so the Activity you're launching is on Top which
means B will be removed from the previous position :

In B where you launch C add this flag :

Intent i;
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

[android-developers] Setup Multiple Alarms

[LatoGT]

Hi there,

I have some problems when I try to setup an alarm. I am using the
AlarmManager to set an alarm. This alarm is picked up by my Receiver
that creates a notification.

My first problem: When I setup two alarms, my notification thats init
by the alarm event always shows me the first input parameter. Whats
going wrong?

My second problem: I read that I should use an id for the notification
to cancel it, when its submitted. What is the best way to create
different ids? I just used javas math. Although the ids are not equals
in my tests, it is not really a good solution. Any ideas?

Here is my code. Although the titleString is not the same like in the
first init (my Log entry in initializeAlarm() shows that the first
input not equals a second input) the onReceive method tells me that
todoTitle is always the same.

private void initializeAlarm(String titleString, String alarmString){
if(alarmString != null && alarmString.length() == 16){
Intent intent = new Intent(this, AlarmReceiver.class);
intent.putExtra("todoTitle", titleString);
PendingIntent sender = PendingIntent.getBroadcast(this, 0,
intent, 0);

SimpleDateFormat sdf = new SimpleDateFormat("-MM-dd 
HH:mm");
Date date = new Date();
try {
date = sdf.parse(alarmString);
} catch (ParseException e) {
e.printStackTrace();
}
Calendar cal = Calendar.getInstance();
cal.setTime(date);

// Schedule the alarm!
AlarmManager am =
(AlarmManager)getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
sender);

Log.v("test",intent.getStringExtra("todoTitle"));
}
}


public class AlarmReceiver extends BroadcastReceiver {

@Override

Re: [android-developers] Re: Is there a way to request permissions from a user as you need them?

[Brad Gies]

Yeah... I agree with that, and I'd like to add that what I would really 
like to see is a(n easy) "Monitor this App" setting when you first 
install it if it has internet access. How I think it should work is that 
if the user wants to monitor the app, every outgoing packet (and maybe 
incoming) would be logged and then the user could view what was sent in 
the "Manage Applications" section of the settings. That way, it would be 
a sure thing that any malicious app would be caught very quickly by some 
user and then they should have an easy way to flag it so that it can be 
banned from the market (with some kind of review obviously).


Something like that would be a tremendous boost to Android as it would 
be perceived (even by the general public) to be very secure.

Let me try this from an end-user perspective.  Obviously, the whole

As an end user, I only care one and ONLY one permission:  INTERNET.  I
only look for that one permission and the rest is just noise and might
as well not even be shown.  Why?  Because I know as long as the app
has no way of getting my personal info off my phone, I am good, as far
as I am concerned, the app can read all my passwords and credit card
info it wants, if it cannot do much with it anyhow.

That said, the way the Internet permission is implemented is poor and
doesn't really tell you anything useful on which I can make my
decision on.  Currently, if I see "Internet" and need to scan the
other permissions as to what else the app can do and send out to
whomever.

What I would like to see is the Internet permission broken up into:

- Full unrestrictued internet access:  This is fine for a replacement
browser, but if anything else requests it, I probably wouldn't install
that app.
- Local network access only (for printing or network management apps.)
- An spelt out protocol/domain list that the app declares it wants to
have access to and nothing else be allowed.  This should be the most
appropriate for the majority of the apps.

I think there is enough evidence that asking permission at time of need
doesn't generally work -- see the MIDP experience, Windows Vista/7 security,
etc.  There is a fundamental problem that at the point you ask the
permission, the user is wanting to accomplish some task at hand, and all you
are doing is bugging them.
And it gets much worse when you consider applications being able to run in
the background.  Do permission requests pop up on users from the background?
  Does a notification get posted that they respond (or not respond) to at
their leisure?
If you have a wall of permissions, the first thing I would suggest is
looking at those and seeing if you can trim it down.  In fact, doing things
that make it easier for apps to make use of lots of permissions are to me
counter-productive -- it is a good thing to make lots of permission use a
harder road.
I just had a look through the apps installed on my phone, and the *vast*
majority of them only require a couple permissions.  So someone who is using
a large number of permissions is going to stand out from what user's
normally see, as well they should.
 From the platform side, we also need to avoid making it easy to have lots
of permissions.  We need to be continuing to design the platform to reduce
the permissions that apps need.  For example, the window flag to keep the
screen on avoids the need of the power manager permission for most
applications; we should beef up our intent interactions with the contacts
app so applications can work with the user to select and modify applications
through that without using permissions; etc.

Re: [android-developers] Re: Is there a way to request permissions from a user as you need them?

[Brad Gies]

Yes.. we do... and I normally don't disagree with you :). But, in this 
instance.. I REALLY do.


Let me expand on why I think it is a failing, and maybe you will see 
where I am coming from.


I'll use the Window Firewall as an example as it is the closest example 
I can think of. It deals with permissions and security. This may be more 
of a manifestation of how I use my computer, but I think many people 
share this :).


Assume I have a new install of Windows. I'm not very security conscious 
(I'm truly not.. if you want my email accounts, I have thousands more I 
can switch to, so I don't care), but I set my firewall to lock down 
everything because I do want some security, and otherwise I'm wide open. 
Then I start to install my programs. At this point none of them have 
internet access. Then one by one I start running them. Some of them will 
immediately popup the "Firewall is Blocking me" dialog. No problem 
I'm still in the installation phase anyway. When that happens, if it's a 
program I REALLY trust, I just grant the the "Allow Always" option. If 
it's a program I don't have complete faith in, I only grant the "Allow 
Once" option, and I pull out Wire Shark before I respond and monitor 
what it's doing. Then when (and if) I trust it, I give it the "Allow 
Always" option.


Doing it that way makes me feel very secure, even though I don't have 
big issues with security in the first place.


I really don't think I am the only person out there that feels this 
way I think Android would benefit from this.


Now.. do you get my point of view?... I'm not asking you to agree in 
terms of changing how you do things... you may work differently... but I 
think it's a valid point of view.


The way Android does it now. I just accept whatever the program asks for 
because until you use it, you don't really know how it wants to use the 
permission. By waiting until it wants to use the permission, I can make 
a (slightly) more informed choice on whether to grant the permission or 
not, especially if I have the option of saying "YES", "YES, but monitor 
it", or "NO", and that makes Android not only more secure but 
communicates that security to the user in a very effective manner.


Brad.

Re: [android-developers] Re: Best background practices

I suppose you'd be better off with a service per service instead of
one god service. The reason is that it make the code cleaner - you
don't need to manage multiple alarms and network connections in one
class. An exception would be a service that just does one kind of
thing, but handles a queue of requests. To avoid copy and pasting
common code, use a common abstract base class that extends Service.

Ok, it's what I wanted to do. One thing that I'd like to get better
explained is: I am aware that the service(s) run on the same thread of
the ui, so if I have more than one thread will they share the same
thread?? If they listen to the same broadcast for example, will the
intent be queued and served from one service at the time?

It's just curiosity, I know that the time consuming operations must be
performed in async tasks or threads.

Thanks for pointing this out.

I hadn't noticed that feature of Androlib before, but this is a great
feature. I had an "user" making repeated comments on my app, and I
couldn't quite decide whether he was a legitimate user or an idiot.
Checking his history of comments turns up 90% of his comments of the
type "Eh", "Gay", "Lame" and "Sux". Good to have that question sorted
out.

Re: [android-developers] Re: Best background practices

[Frank Weiss]

I'm not a total expert on this...

Threads are really just a way of running multiple stacks/program
counters in the same address space. It's fair to assume they are
time-sliced. Services and Activities are run in a single UI thread
(AFAIK) and the precessing model is typical UI thread which calls
event methods on them sequentially (they don't really run like
classical processes). AsyncTasks run from a thread pool. The first few
can run concurrently, but after that the next one can't start until
another one is finished. Network connections are also pooled (AFAIK),
so that after you open a few, additional ones queue up.

To get workable background processing/networking, you'll probably need
to use alarms/saved state, since an app's process can be summarily
dismissed any time by the OS when other apps need resources. Although
some background processing that takes just seconds you might as well
do with an AsyncTask in an activity instead of a service.

Don't expect SDK apps to get any processing done when the device is
sleeping or turned off (I'm sure you know that already).

[android-developers] Re: Is there a way to request permissions from a user as you need them?

[Greg Giacovelli]

So I am not saying use a dialog everywhere. I am saying on a per
application basis. The problem with Windows Vista was that it was
everywhere. I am saying in addition to a small wall of permissions
representing the what permissions are needed for the core
functionality of the application, you also allow a upgrade
permissions. A user should not be scared to install an application
because of optional features of an application that compliment, a core
functionality. Apple, a company that basically gives all developers
access to frightenly everything, still prompts users on a per
application basis for location, notifications, etc.

I would say I would like to shrink that permission list but in order
to have functionality enjoyed by some, I am forced to have permissions
granted by all. Also doing a quick look at your list on your phone is
not.a really good test, you are a developer, ask someone outside the
tech industry the something for some good feedback.

I am not trying to be difficult I am just basing this on being an
iPhone user previously. This platform has more potential I think but
the focus on tech more so than user experience is what prevents this
platform's growth.

Re: [android-developers] Re: Android Market, google checkout minimal sum to be collected before payment.

[Brad Gies]

Has anyone tried removing their bank account information and then when 
the amount is high enough that you would like it deposited, adding it 
back in just until you get the deposit? Or... maybe there is a way to 
disable/renable the account without removing it, so you don't have to 
set it up every time?


My apps are free so I don't have the problem, but it seems there should 
be some way to do it.

No, you get a single payment every work day.  If you don't like that
schedule, because who wouldn't like 22 small deposits a month, you are
out of luck.

I don't think so, at least I've not found a way from looking around.
Checkout was really tacked on to Android and in no way designed to support
small transactions for virtual goods.

Oh my, I so very disagree with this.

The current design is *very* much designed for end users.  In particular, it
is designed for *most* users.  Not geeks, like you and me and the others on
this thread.

In the vast majority of cases when people are unhappy with the way things
work, the requests being made are coming from geeks for them to do more
geeky things.  This thread is no exception.  And this is very much an
anti-goal.

Sorry but you are wrong.  When my wife got her Droid and started installing
apps, she quickly came to me asking about a game she was installing that
said it would read her contact data.  She knew what that meant, and wasn't
happy about it, and decided not to install the app.

In addition, there are so very many good reasons for an app to have access
to the internet, that basing all decision on that is ridiculous.  So you
aren't going to install multi-player games, or an app that lets you post to
twitter, or countless other things, or need to have strong faith in any such
app because you have no idea what stuff about you it will have access to?
 We aren't going there.

What does local network access on a cell phone even mean?  And how many
normal users are even going to really understand what this means?

I will claim again that this is another example of designing for geeks.

That said...  I would like to be able to have a way to enforce that apps can
only get to domains they declare they need.  In fact, we looked at doing it.
 You know what?  This is hard.  It is hard to enforce in the platform (think
about domains vs. IP addresses and how the kernel is going to figure out
that a particular socket is valid for the app).  It is hard to make
meaningful (think of the tricks you can make with safe looking domains that
redirect elsewhere).  It is hard to present to *normal* users in a
meaningful way that they can make a good decision about.

Of course if you figure out a good implementation of this, I'd be happy to
review the patch.

My focus right now is on simplifying permissions, giving apps other ways to
do things that are safe without requiring permissions, etc.  Making things
more complex for users is not desired.

[android-developers] Re: Negative comment causing drop in sales

[cyxb]

My favorite one-star Market comment: "Rate one star if you want the
full version to be free!".  Or another 1 star classic: "Make the full
version free cuz my mom won't let me buy it"

People are like lemmings.  A comment like that will cause an avalanche
of similar comments.  Likewise, a great comment may also trigger other
people to post nice comments.  I suppose it all evens out in the end,
or at least that's what I tell myself.

I can guarantee you that if this facilities exists, apps will use it
extensively.  We'd have a design that encourages it: showing an app's
permissions up-front before installing is a strong barrier where the user is
most inclined to decide the scope of what the app is doing is not worth
their desire for it and reject it; asking permission later is when the user
is just trying to do things and much more inclined to just say "yes" instead
of canceling or uninstalling the app.

So if I am an app developer...  of course I will declare no permissions at
install, and request them all as needed.  I have a huge incentive to that.

I will say specifically about location -- we should have some additional
facilities to control that, showing the user which apps are using it and
individually turning it off.  But location is a special case (note it is the
only thing that there is a global setting to turn off as well).

And of course we don't have or need a permission for notifications.  A
design that doesn't require a permission but is still safe and secure is of
course best.  That is why I say I'd like us to introduce more ways for apps
to interact with contact data without needing a permission.  To me that is a
much better way to spend time.

I am not trying to be difficult I am just basing this on being an

I will claim pretty strongly that our security is much better than the
iPhone, and is actually a user-centric design without relying on implying to
the user things it is not (such as reviewing apps providing much security).
 There are certainly things about Android UX that can be improved in
relation to others, but we aren't trailing here.

[android-developers] Popping up Toast (or something like it) from a thread

[Bret Foreman]

My user hits a button and kicks off a process that takes 3 steps in
about 10 seconds total. I'd like to pop up Toast messages "Step 1",
"Step 2", "Step 3", "Finished!" as the process progresses. I'm using
the standard Java Thread interface to run the process in a thread and
I've found that trying to pop up Toast from the thread causes an FC.
What is the best way to report this kind of progress - step by step
messages?

if the user never register it will send an event each time he use the

Re: [android-developers] Popping up Toast (or something like it) from a thread

Anything that touches the UI MUST be done on the UI thread.  This is
the main thread that starts your app.
If you start off a thread, you must use an inter-thread communication method.

[android-developers] Column headings in TableLayout

I'd like to have column headings in a TableLayout and I'd like those

headings but it's a little complicated keeping the column widths

She should have had the option of installing the app without that
questionable permission.

Right now, such sensible user control is only available to those who
can modify the .apk, ie geeks..

[android-developers] Cupcake(API3) friendly way to pause/stop sound loops in SoundPool? Any ideas?

[BryBam]

Quick note: I'm using the SoundPool class

http://developer.android.com/reference/android/media/SoundPool.html

What I have here is a simple button that plays a looped sound while
it's pressed. It works great. However, sounds.autoPause(); wasn't
introduced until API 8 and I really need something that is cupcake
compatible (API 3) So i was going through the dev reference site
filtered by API 3 stuff and i saw pause so i figured i'd try
sounds.pause(sound); but it doesn't stop the sound when i release it.
(Maybe i'm just using it wrong?) Does anyone know of a cupcake
friendly way to stop this sound? thanks!

edit: also tried sounds.stop(sound); that didn't work either.

The Code:

My onCreate:

sounds = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
sound = sounds.load(this.getApplicationContext(), R.raw.red_long_one,
1);
Then here's my touch event

@Override public boolean onTouch(View arg0, MotionEvent event) {

switch (event.getAction() ) {
case MotionEvent.ACTION_DOWN:
System.out.println("touch");
sounds.play(sound, 1, 1, 1, -1, 1);
break;
case MotionEvent.ACTION_UP:
System.out.println("up");
//autoPause does not work on anything lower than sdk8
sounds.autoPause();
break;
}

return false;
}
I don't understand why sounds.stop(sound); doesn't seem to work, that
seems to but what any article i read recommends to do

I think it's worth noting that if i use sounds.stop(sound); it works
ONE time then after that it won't stop after i let go. but the first
press and release it works as intended.

Now, I know on the andoird site it says streamID and not soundID but i
have no idea how to get the streamID

[android-developers] Re: how to set progress dialog time out

[Kumar Bibek]

Spawn a thread, wait for a few seconds, and then dismiss the dialog.
There's no default way to set a timeout.

May be you can over-ride the toast class to create one to stay afloat
longer.

[android-developers] Re: Is there a way to request permissions from a user as you need them?

[Mark Carter]

I've just released an app that requires READ_CONTACTS for the sole
purpose of displaying names instead of phone numbers (of SMS
messages). Its really not necessary at all but just looks better.
Being able to specify that permission as optional would be much
better. If the user rejects it then the app can happily just show the
phone number instead.

[android-developers] Re: Game math/logic calulating movement

[Jeffrey]

The problem is that it is only moving the image one direction along
the slope of the line. I've tried making a condition that checks to
see if the target area is to the left of the current position, and if
so then make the X/Y differences negative, but that works very
sporadically, and make the image move in crazy ways sometime.

Okay, figured it out. I had some remnants from an old system still in

correctly.

[android-developers] Re: Why is DialogPreference abstract?

[Kumar Bibek]

First of all, DialogPreference is not meant to show a normal dialog
anyway. This is used in Preferences.

I would suggest that you extend the Dialog class. That should help you
in all ways to show your license. You can customize the layout,
buttons, title etc.

[android-developers] Layout question

[Michael]

Hi,
I would like to create a layout that would have a Checkbox, then a
divider, then a listview with single choice mode.

I tried this


http://schemas.android.com/apk/res/android";>









with this


lView = (ListView) findViewById(R.id.ListView01);
//lView = (ListView) findViewById(R.id.list);
//  Set option as Multiple Choice. So that user can able to select
more the one option from list
lView.setAdapter(new ArrayAdapter(this,

android.R.layout.simple_list_item_single_choice, lv_items));
lView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

lView.setItemChecked(0, true);


but it didn't work.
I can't seem to get a checkbox on top of a listview properly. I also
would like for the words to be to the left of the checkbox. Any help
on this would be much appreciated!

The project is definitely worth completing, but it's discouraging to
not have a slick interface unit like a tree available. However, I'll
think about alternatives in the meantime.

RE: [android-developers] Popping up Toast (or something like it) from a thread

[Tommy]

check out runOnUiThread() its exactly what you need. I don't remember the
syntax right off the top of my head but if you google runOnUiThread android
you'll get an example.

Subject: [android-developers] Popping up Toast (or something like it) from a
thread

My user hits a button and kicks off a process that takes 3 steps in
about 10 seconds total. I'd like to pop up Toast messages "Step 1",
"Step 2", "Step 3", "Finished!" as the process progresses. I'm using
the standard Java Thread interface to run the process in a thread and
I've found that trying to pop up Toast from the thread causes an FC.
What is the best way to report this kind of progress - step by step
messages?

RE: [android-developers] Layout question

[Tommy]

Try using a relative layout linear from my understanding won't let you lay
objects on top of each other. Or an absolute layout but those aren't too
good when it comes to scaling up/down for different screen sizes.

Subject: [android-developers] Layout question

Hi,
I would like to create a layout that would have a Checkbox, then a
divider, then a listview with single choice mode.

I tried this


http://schemas.android.com/apk/res/android";>









with this


lView = (ListView) findViewById(R.id.ListView01);
//lView = (ListView) findViewById(R.id.list);
//  Set option as Multiple Choice. So that user can able to
select
more the one option from list
lView.setAdapter(new ArrayAdapter(this,

android.R.layout.simple_list_item_single_choice, lv_items));
lView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

lView.setItemChecked(0, true);


but it didn't work.
I can't seem to get a checkbox on top of a listview properly. I also
would like for the words to be to the left of the checkbox. Any help
on this would be much appreciated!

[android-developers] Cannot use explicit intents to call another application?

[Anil]

Was trying to call another application using an *explicit* intent, but
am finding it does not seem possible.
I do not wish to use implicit intents.
To test it out, try calling the YouTube main activity.

Intent i = new Intent();
ComponentName  cn = new
ComponentName("com.google.android.youtube","com.google.android.youtube.HomeActivity.class");
i.setComponent(cn);
startActivity(i);


I get this error:

08-29 00:54:26.598: ERROR/AndroidRuntime(7332): Caused by:
android.content.ActivityNotFoundException: Unable to find explicit
activity class {com.google.android.youtube/
com.google.android.youtube.HomeActivity.class}; have you declared this
activity in your AndroidManifest.xml?

Does anyone know whether this is possible? (using explicit intents to
call another application)
thanks,
Anil

Michael,

You didn't explain on how exactly this did not work, but...

I believe you want ListView height to be "fill_parent".

Re: [android-developers] Cannot use explicit intents to call another application?

[Kostya Vasilyev]

Don't need the trailing ".class", take it out (in component name).

Trailing .class is Java syntax to get the class object of another object,
that's why you often see it for starring activities and services in the same
application.

Class *names* however don't have ".class" at the end.

Re: [android-developers] Column headings in TableLayout

[Kostya Vasilyev]

What I ended up doing in my app, is:

I use a ListView instead, and, just like you, I created a header view that
doesn't scroll.

ListView items, as well as the header, use RelativeLayout. Some views are
positioned left to right, others, right to left, and one view in the middle
grows when in landscape mode.

I'd like to have column headings in a TableLayout and I'd like those
headings to remain visible when the table is scrolled vertically. One
option is to create a separate TableLayout just for the column
headings but it's a little complicated keeping the column widths
consistent between the two tables. Is there a better approach?

Re: [android-developers] Re: Negative comment causing drop in sales

[Kostya Vasilyev]

One of my apps received more than the usual number of "can't open" comments
within the last week.

I guess the word "widget" in its title isn't understood for some reason

My favorite one-star Market comment: "Rate one star if you want the
full version to be free!".  Or another 1 star classic: "Make the full
version free cuz my mom won't let me buy it"

People are like lemmings.  A comment like that will cause an avalanche
of similar comments.  Likewise, a great comment may also trigger other
people to post nice comments.  I suppose it all evens out in the end,
or at least that's what I tell myself.
