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

[android-developers] Re: upload image to php server problem

You need to tell us where the error is raised if any.

In your php you might want to try to use the realpath function to get
the true path to your upload folder :

I've resolved the issue. Not sure if this is a bug, feature, or is

you supply to your ExpandableListAdapter's constructor needs to
include the _ID field of the child table.

[android-developers] Re: Paid vs Free, My Early Experience

2010-08-27 Thread Zsolt Vasvari

Answers below:

 * Put some context around doubled.  From 1 to 2, 100 to 200, 1,000 to 2,000?

From about 7-8 to about 15-16.  The app is $7.  So it went from
probably not worth doing it to a nice chunk of pocket change.


 * How many cancels are in these numbers?  I've got to believe that with a
 less informative, and more catchy message, people know less about what
 they're buying and end up canceling when they find out it's not what they
 expect.

None, I only count money in the bank.  My cancel rates have actually
gone down to about 10%, from about %25 before.



 * It would be interesting to see the before and after descriptions you're
 using in the market for your app.

The app is called anMoney, you can see the current description.  The
previous one was basically just a feature list.


 But without the feature list, how will you catch people that are
 looking for your app 's features?
 This may work if your app is well ranked in the list maybe...

That's the point of this whole discussion.  My app is the highest
rated star-wise if I look in the Finance Paid category on AppBrain.


 Did you update at any point in this time frame?

No, I updated about 3 days earlier before the change in description.


 Did you happen to get featured at any point in this time frame?

I don't know, but I extremely seriously doubt it.


 Were there any new Android devices released in this time frame?

In the last week, I don't believe so.

The other things I noticed in the past week are:

- I have a lot more female purchasers.  Around 35%.
- Fewer support questions.  Went from 3-4 a day to 1-2.

[android-developers] Re: String being truncated when its long

2010-08-27 Thread Brion Emde

I'm pretty sure that if there is a limit, it is much bigger than what
people are saying here.

I wrote a little Twitter example on Android and just doing the
home_timeline query can return up to 200 tweets, each up to 140
characters, plus overhead. That's 10s of kilobytes per GET request.

See if looking at this code helps:

 My knowledge of the HTTP protocol is poor to begin with, and my bad

 normally the software used on each end should hide this sensitivity so
 that you can deal in complete data streams up to some significantly
 larger limit.

 It could be that something in your config is causing this transfer
 size to be exposed.  It's also possible that your coding style is
 opening you up to being sensitive to data stream values.  In
 particular, null may be being returned from readLine at the end of the
 block, even though there is more data in the transmission.  (I don't
 know that such is possible -- just speculating.)

 Finally, it's possible that the failure is occurring on the
 transmission end, perhaps due to an EOF character embedded in the
 source data or some such.

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

Yes what happens during an update is the app is first force stopped (all
processes killed, alarms unregistered, etc), then then the new version is
installed.

It seems promising that clear data would fix the problem; this is most
likely then an issue you can deal with in your app rather than something
systemic.  The first thing I would look for is any code writing data that
could cause problems if it was killed in the middle of executing.  Databases
should handle this, but you need to deal with it yourself for raw files...
 for example SharedPreferences does this in its commit by writing the
contents into a new file, and then switching from the old file to the new
file once the new one is complete.

 Might be. It's only a handful of people (well, more than a handful for me)
 but still few in comparison to the total install base, so there's definitely
 something they're doing that's triggering the problem.

 I would think the update process would kill the app if it's running, but
 maybe not.

 Also, got confirmation from the second person that clearing the data solved
 the problem.

[android-developers] Making sure that ... (not an ellipsis) is not wrapped

2010-08-27 Thread Fabrizio Giudici


-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

In some cases I have messages, typically shown in a toast message,
where there are three trailing periods. For instance, bla bla bla.
Please wait Note that this is _not_ an elipsis, as the string is
not truncated. The problem is that sometimes the string is wrapped at
the end of line and I get two periods in the first line, a newline,
and then a single orphaned period in the next line.

I'd like to have the ... not broken by any means. How can this be
done in a reliable way? E.g. is there any Unicode single char
guaranteed to be available in all Android appliances that
gets rendered as three periods?

[android-developers] Re: Read the data in Intent

2010-08-27 Thread Indicator Veritatis

As a newcomer to Android, you absolutely must read
http://developer.android.com/guide/topics/fundamentals.html. You must
not only read it, but study it thoroughly. Thoroughly enough that you
can answer, for example, reading questions such as the following:

1) What are the four application components out of which all Android
applications are built?
2) How does Android guarantee that application processes are isolated
from each other?
3) How do different application components of a single application
share data with each other? Name ALL the ways Android supports.
4) How do completely independent applications share data with each
other?
5) Can a Service and an Activity in the same application share a
thread?
6) What is the difference between a Service and a background/worker
thread? Or a Broadcast Receiver?
7) Which class is used to manage interprocess communication between an
Application and a ContentProvider?
8) Which application components are 'activated' by an Intent?
9) Some application components run quickly to completion, and then are
deactivated. Others must be explicity deactivated. Which are which?
10) How does an Activity/Service decode the data in an Intent?
11) What are the differences between the three activity states:
active=running, paused, and stopped? In which of this is the activity
visible, in which does the user have input focus?

If I understand your question correctly, 3, 4 and 7 are most directly
relevant to your question. But in order to understand the context for
the answers, you really do need to read all of
http://developer.android.com/guide/topics/fundamentals.html well
enough to answer all the above questions and more.

Good luck with your reading;)

[android-developers] Re: String being truncated when its long

2010-08-27 Thread Achanta

First of all thanks everyone for replying.

I just discovered that the problem is not with my code but with the
number of lines that the logcat is displaying.
The problem was that I got a problem in my json reply format and my
parsing code spits an error. So I started trying to debug it by
printing the response json string in logcat. This is being truncated
always and I was guessing till now that the reply itself is being
truncated.

So today I started plying with the response string builder and has to
write funny snippets to count characters and detect the characters at
positions I was expecting and I found that the response was being
returned completely.
I also tested my code on some other large stings and I discovered that
the logcat has a limit on the length of the string that it displays or
atleast it looked so. That was why my responses were being displayed
as truncated strings and I thought that its the problem with my code.

So it is working fine as the code is earlier and the only problem was
that the logcat doesnot display the complete string. But it does not
cother me anymore for this problem.

Thanks again everyone for trying to help.

[android-developers] Re: Problem with reading contacts on Samsung Galaxy Europa

2010-08-27 Thread Albert

Hi Zarah,

I have reports of the app launching a blank screen but not crash. I am
getting a Samsung Spica this week but you have already stated that it
works there so that won't be of any use. For my app is wan't so
critical so I just instruct Galaxy S users to insert those details
manually. The best is probably to contact Samsung development
department and find out what mess they have done and from there find a
suitable solution.

If you ever find a solution, please let me know.

[android-developers] Re: Read the data in Intent

2010-08-27 Thread Indicator Veritatis

I wonder if he meant 'Service' instead of 'Server'. Then the question
would at least be cogently phrased. But if he really meant 'Server',
then he probably does not realize he has to set up his own code to
access the server over the Net, isolated from the main UI thread. If
he wants to do that as a separate application component, as a Service,
then that is up to him. Then he can send messages back and forth
between the UI and the Service with Intents, but that will probably be
inadequate for passing data back. So he might be better off shuffling
all the Server/Http stuff to an AsyncTask in the same Application. I
don't see how we can tell him which way is best to go without knowing
more about the service served by the server.

Re: [android-developers] Re: String being truncated when its long

Might I suggest you try debugging in Eclipse instead of with logcat.
You can breakpoint and step through the code and inspect variables. It
gives you much better insight into what's happening in your code than
logcat or toast.

Zsolt, I work at a digital advertising agency and have been sharing

and of course, obvious. When I remarked that many Android developers
are, well, developers, they joked that maybe our agency should start
helping mobile app developers market their apps. Thanks again for

[android-developers] Debugging Droid X-specific issues

2010-08-27 Thread Paul Tongyoo

Hi Developers--

So I've run into a Droid X-specific issue but am not able to reproduce with
my emulator AVD's.  Is there a Droid X-specific AVD that I should be using?


Thanks in advance!

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

Thanks for the continued help.

On Fri, Aug 27, 2010 at 2:22 PM, Dianne Hackborn hack...@android.comwrote:

  The first thing I would look for is any code writing data that could cause
 problems if it was killed in the middle of executing.


That makes sense, but that's also why I'm confused. The main issue I've had,
for which I have nearly 30 reports now in each version of my app in the dev
console, has nothing to do with data access. Unless I'm really missing
something.

I have a base class reference that should be set to the appropriate instance
of a derived class type based on user selection.
These derived type instances come from a manager class, of sorts, that holds
the instances. There is one static instance of this manager class in the app
since it's global, constant data. So it should be initialized, along with
it's internal data it manages, at all times. None of this involves any data
access.

Some pseudocode if it helps:

// In Manager class
public Manager
{
 private MapString, BaseRef refs = null;

 public Manager()
 {
  refs = new TreeMapString, BaseRef();

  // Explicitly add derived instances of BaseRef
  refs.put(Key, new DerivedInstance());

  // add more ...
 }

 public BaseRef get(String key)
 {
  return refs.get(key);
 }
}

//In Static access class
public StaticClass
{
 private static Manager manager = new Manager();

 public static Manager getManager() { return manager; }
}

// Then, finally, in the class where the crash occurs
BaseRef baseRef = StaticClass.getManager().get(userSelection);


Userselection is the value chosen by the user from a list pre-populated by
the Keys in the Manager class to begin with.
So if the user was able to make the selection, the key was there at the
start of the Activity, and in the manager where it originated from.

baseRef, which is obtained from that single manager's list (which is
essentially hard-coded), is later used elsewhere and ends up being null.

There is no file data access involved anywhere in this Activity besides
using SharedPreferences for exactly one option.

Also, now that I've typed this out, this goes against the idea that statics
are the problem since I would have had the null pointer at the point where I
try to access the Manager class. Instead, it appears to be valid but for
some reason its internal data, which is set on construction, is not.

It's worth noting that I've seen this problem to a lesser extent before I
added this manager class stuff, but since adding it last week, the problem
seems to have exploded with a fury. But again, not sure if that's a result
of a larger user-base over two months since last major update.

I think at some point I'll start polling my users to see how many of them
continue to see the issue after updating. Since I've instructed them, in
nice big letters, to try uninstalling first, I expect not to hear any more
complaints for now, but I'd rather fix the problem than band-aid it like
this.

[android-developers] AccountManager auth token and user interaction

2010-08-27 Thread Federico Paolinelli

Hi all, I am trying some interaction with my phone and an appengine
server, and I have the following question: there may be a case in
which the account manager need the user to confirm that he wants to
authorize the account. Will it be just once for the installation of
the application? Or it can happen in any time that my app still need
the user interaction?

I need to know this because I would like to interact also in
background, and think the user would be disappointed if my app stops
doing its job because the authorization was sort of expired.
Unfortunately I did not manage to find any details in the docs, I just
noticed that if I run my code it asks for the authorization only the
first time is installed on a phone.

One more question: is there some place in the settings where I can
reset the authorization so I can try again the first interaction?

Thanks a lot.

Federico

Have the keys changed between releases of the application? Is the selected

[android-developers] T-Mobile G1 won't appear in 'adb devices' list

2010-08-27 Thread Mike

I'm trying to connect to connect to my T-Mobile G1 to test a simple
android app I an creating. I cannot get it to show up in the list of
connected android devices. Here are the details:

- 32-bit Windows XP
- I have enabled USB Debugging on my device
- I am not prompted with the New Hardware Wizard when I plug my device
in, it is merely seen as a new removable drive. It does not appear
under any other categories in Device Manager, nor is there a new
Unknown Device entry anywhere to be found
- I have tried Update Driver and select the driver that Google
provides for their official developer devices, but it says this
driver does not match your device or something to that effect.
Probably because it is expected a device type other than Disk Drive
- I have tried uninstalling the device under Disk Drives and
plugging it in again but it always gets reinstalled automatically as a
Disk Drive
- I have tried uninstalling the device, manually installing the Google
driver from the INF file and plugging in the device and it is still
only recognized as a Disk Drive
- Most importantly, I get a blank device list when I run adb devices
from the Android SDK tools directory before and after each step I
tried

After hours of scouring the web I get the distinct impression that a
new device category should be popping up in Device Manager if the
driver is installed correctly, but I have not been able to get the
device to come up as anything other than a new Disk Drive

Thanks in advance

Re: [android-developers] Re: Paid vs Free, My Early Experience



Hah.. yes.. I guess non developers have as many jokes about developers 
as developers have about them :).


But it should be obvious to any developer:

How many developers have experienced the other person's eyes glazing 
over and their mind shutting down effect when they are excitedly 
telling their friends and family about everything the latest 
technology/gadget/device can do. I would suggest that it's really close 
to 100% and if you haven't experienced it, it just proves that you are 
totally unobservant about other people :).


And yet they still want to list all the features in their marketing 
materials it just boggles my mind :).

[android-developers] Best background practices

2010-08-27 Thread Federico Paolinelli

Hi all, my application needs to perform some activities in background
(like interacting with the network and check the location and some
other stuff), having or not the main activity visible.

Which is the best way to achieve this? Should I write a service for
each kind of job? Or just one service that performs everything?

I am aware that I will need to launch threads / asynctasks in any case
because the service runs on the same thread of the ui, but maybe
having several services is a more clear and readable structure...

Thanks to everybody.

2010-08-27 Thread Zsolt Vasvari

 Yeah, I don't know if I'd be willing to claim this entire theory is
 validated based on 8 more sales in one week for one app  ...

8 a day, for a week.  But it the perecntage that matters.  And today
it's up to 19 so far. (21 - 2 cancelations)


 I hope you don't mind me linking, the old one is still on 
 cyrket:http://www.cyrket.com/p/android/com.zvasvari.anmoneyp/

Not at all.  Thanks.



 I was typing as Chris replied, and I agree that including big names like
 Quicken and Microsoft probably helped in driving people to your app. Which,
 ironically, is a great marketing tactic =). And yeah, you've got some typos
 / misspellings which are generally not good marketing =P (unless intended,
 before you point to me =P)

Thanks to everybody for pointing them out.  Fixed the errors -- that's
what happens when you try to edit your description in that tiny window
on the Market app page.


 I noticed you have a free version as well. Did you update that too? That's a
 marketing too in and of itself.
 I always update my free version at the same time and indicate what's new in
 the full version only so the freebiers will consider upgrading.

Yeah, the free version says the same thing, minus the 24hr thing.


 Worth a shot =P

How does somebody get featured?


 How did you determine this? Just curious.

Just by looking at the names in Google Checkout.  An overwhelming
(90+) percentage of my users are from the US and the UK, though I've
yet to see a female name from a non-US buyer.


 And of course he used the try it risk-free 24 hours refund argument :)
 And I have to say it is a very clever message Zsolt.

Thanks, Yahel, but I've read that before that very few people actually
ask for their money back on anything.  It seems to hold true even if
it entails a single click.

Nope, they're hard-coded and were introduced in the last update.
So where I have Key is a string literal I use to ID the derived instance.

So it's like:

refs.add(Option1, new Derived1());
refs.add(Option1, new Derived2());

and so on.

Then in a drop down, the user can select Option1 or Option2, each option
being obtained from the hard-coded list.
So yeah, no saving or restoring of the keys. All in the code.

[android-developers] Re: Optimizing list view scroll

2010-08-27 Thread ls02

I did some profiling and it turned out significant time is spent on
loading images. Each listview item has a distinctive image. i have
thousands of items in my listview so I cannot cache them. I tried to
create an image on card folder cache of either PNG or JPEG image files
of exactly the same dimension as the images I render in listview item
ImageView. It helped but still not ideal.

I thought about saving uncompressed bitmap data to a an image cache
file with hope it will be faster to load and render since the image
won't need to be decompressed. But i didn't find any class or method
to save and load uncompressed bitmaps. The only way I see to save the
image to a disk file is Bitmap.compress which can be either JPEG or
PNG (BTW, which one from these two is faster to load and render?).

I also thought about loading images in worker thread but this appears
to be very complicated and I am not sure it will help and won't create
other problems. I would have to create a queue if currently visible
items and have to load images inside that thread. I worry that while I
load a title image it is already scrolled out and becomes invisible.

I already optimized each list item view as much as I could. Now I am

Another approach is to build item view dynamically each time view is
requested in the adapter getView method. In this case I can only add
at run time those elements that are truly needed for current item
state but this requires inflating item view every time.

Finally  the third approach is most extreme is to have one custom view
and draw everything myself. This of cause requires a lot of work.

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

2010-08-27 Thread Greg Giacovelli

I think I see where you are coming from to a point however honestly I
dislike the global statement. I mean a wall of permissions is going to
turn into white noise to users (in which case the permission could be
for Brick for all they care leading to spam) or paranoid users (in
which case your platform dies from no use, but is perceived as lack of
creativity from developers). I am just saying it would be nice, from a
user perspective and from a developer perspective if I could
optionally request a permission and/or upgrade to a permission via
user interaction (through a system UI that could persist a No or a
Yes). I mean if it's at install time, how do you explain to a user why
the permission is needed (They aren't engineers remember, and it's
only like 256 characters in the market description field).

Just my two cents.

On Aug 27, 9:45 am, Dianne Hackborn hack...@android.com wrote:
 No it must be done at install time.  Honestly, this is better than prompting

 the task at hand is installing an app.

 You can't intercept URIs without going through a system UI where the user
 decides what to do.  Also at that point the task they are doing is look at
 this thing I selected, so the decision they are making (pick which will
 show the thing they are wanting to look at) is relevant to their task at
 hand.

[android-developers] Re: MenuItem with Spanned elements in their titles

2010-08-27 Thread Greg Giacovelli

Just to close this off, apparently in MenuItems for context menus you
need to use a string for the condensedTitle because the internal
EventLog is dumb.

On Aug 19, 7:28 pm, Greg Giacovelli miyamo...@gmail.com wrote:
 Hi I was just trying something and realized this doesn't seem possible
 due to the debugging code in the android OS.

 I register a context menu on an AdapterView, via
 registerContextMenu(mAdapterView), and then implement the
 onCreateContextMenu, like this:

 CharSequence title = context.getString(R.string.txt, userName);
 title = Html.fromHtml((String) title);
 MenuItem item = menu.add(ContextMenu.NONE, ContextMenu.NONE,
 ContextMenu.NONE, title);

 The context menu displays correctly, however when it is clicked I get
 an illegalArgumentException from the EventLog class when it tries to
 print out the condensedTitle.

 So I have found without setting the condensedTitle explicitly to
 something that is a String this occurs. Why is this marked as a
 CharSequence if it cannot handle it?

[android-developers] getContentHeight pixel density

2010-08-27 Thread Tom

i'm trying to use getContentHeight to compute how much scrollable
content i have remaining in a WebView.  when i run my app on devices
w/ different screen dimensions getContentHeight appears to return the
same value while the getHeight() on the container of the WebView
returns different values (larger for higher density screen, smaller
for lower density screen).

question: what units does getContentHeight return?  i would expect
this value is actual pixels, and thus would change for the same
content on different devices with different density screens.

thoughts?

[android-developers] Using Bouncy Castle with an Android app

2010-08-27 Thread fba

Has anyone managed to use Bouncy Castle in one of their apps?   I need
to be able to do detailed manipulations of x509 certificates (generate
CSRs, generate key pairs, convert between different certificate
formats, etc.), and BC seems the best way to do that.

I have tried putting the bcprov library in to my project, and then
just using BC like I normally would.   When the app is installed, a
large number of DexOpt: not verifying... messages pop up.  I suspect
this is because BC is already used in Android.  However, when I make
calls to certain methods in certain classes, I get errors like this :

java.lang.ClassCastException: org.bouncycastle.asn1.DERSequence


I suspect this is because of ambiguity between the classes that are
included in the OS, and the ones in my project.

Is there any way to get around this?  Maybe tell my program to use the
BC library that is included with it and ignore the one included in the
OS?

Or, could I get around this by making sure that I am using the same
version that is included in the OS?   (Or, in a nutshell, is the
ClassCastException likely to be a problem because the parameters
defined for the same method names don't match?)

Thanks for any help!

[android-developers] Re: T-Mobile G1 won't appear in 'adb devices' list

2010-08-27 Thread fba

I ran in to a similar issue last year.   After much searching and
messing around I managed to get it working by using bits and pieces of
various other people's blogs.  I went ahead and blogged about it
here : http://geektaco.blogspot.com/2009/10/of-androids-and-usb.html
.

Basically, it seems that Windows can sometimes incorrectly assign
drivers the first time the device is connected.   If you use something
like USBDeview you can clear all of that out, and get a second shot.
This method has worked for me on an ADP1 (basically a G1), Nexus One,
and myTouch3g Slide.

 - I am not prompted with the New Hardware Wizard when I plug my device

 - I have tried Update Driver and select the driver that Google
 provides for their official developer devices, but it says this
 driver does not match your device or something to that effect.
 Probably because it is expected a device type other than Disk Drive
 - I have tried uninstalling the device under Disk Drives and
 plugging it in again but it always gets reinstalled automatically as a
 Disk Drive
 - I have tried uninstalling the device, manually installing the Google
 driver from the INF file and plugging in the device and it is still
 only recognized as a Disk Drive
 - Most importantly, I get a blank device list when I run adb devices
 from the Android SDK tools directory before and after each step I
 tried

 After hours of scouring the web I get the distinct impression that a
 new device category should be popping up in Device Manager if the
 driver is installed correctly, but I have not been able to get the
 device to come up as anything other than a new Disk Drive

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

On the otherhand, I'd probably want to know if an app was ever going
to ask for a particular permission. Then again, it might be reasonable
if an app, at some point after it's installed, said if you grant me
this permission, I can do this additional function or to fulfill
your request, I will need to use this permission. I suppose, though,
that this would make the security functions of the OS more difficult,
because the OS would need to intervene and get the actual user's
approval of the request.

I don't fully understand what's happening to you because more details
are needed, and generally speaking I think that Android would prevent
you from embedding in your app classes which are already present in
the runtime, but your problem seems to definitely fall within this area.

One possible solution (but it's about the symptom, not necessarily the
real cause and thus not necessarily the best solution) is to use a
static bytecode manipulator that renames packages in a jar. I use
Maven and there is the maven-shade-plugin, but I'm sure similar tools
exist for Ant. The basic idea is that if you have L.jar containing
com.acme.MyClass and A.jar referring to it, with the tool you can
directly feed in L.jar and A.jar and achieve L2.jar and A2.jar where
both the original class and its references have been replaced by
something such as foo.bar.com.acme.MyClass. This works for me (not for
BouncyCastle but for other stuff). With this trick, your source files
stay as they are, but the binary code gets fixed before being
converted to dex.

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

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.

[android-developers] Re: Licensing server, app cracked.

2010-08-27 Thread Lance Nanek

There's lots of information on using ProGuard with Android apps if you
just Google those terms. I implemented it once with one of my apps to
see if it would help my frame rates, but decided not to ship it.
Wasn't much performance improvement in my case and not sure if I want
the extra annoyance of having to convert stack traces back.

  To ensure the security of your application, particularly for a paid

  Properly obfuscating your code makes it more difficult for a malicious

  removing the license check — and then recompile it.

  Several obfuscator programs are available for Android applications,

Re: [android-developers] Re: Optimizing list view scroll

This is an API demo for dealing with data that is slow to load:

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List13.html

You'll of course want to do this a little differently, filling in as much of
each item as you can when binding, and having a background thread loading
images to populate later when they are ready. (Instead of the stuff this
demo does with the scroll state changing.)

I thought about saving uncompressed bitmap data to a an image cache

PNG (BTW, which one from these two is faster to load and render?).

I also thought about loading images in worker thread but this appears
to be very complicated and I am not sure it will help and won't create
other problems. I would have to create a queue if currently visible

load a title image it is already scrolled out and becomes invisible.

[android-developers] Re: Sysinfo CPU load in DDMS not working with 2.2 devices?

2010-08-27 Thread Patrick

OK, looking through the ddmuilib/SysinfoPanel source code
http://bit.ly/amJRR0 it looks like the code just executes
a dumpsys cpuinfo command and then parses the output
to build the pie chart.

On a 1.6 emulator the output looks like this:

# dumpsys cpuinfo
dumpsys cpuinfo
Currently running services:
  cpuinfo
---
DUMP OF SERVICE cpuinfo:
Load: 0.13 / 0.3 / 0.14
CPU usage from 62119ms to 2119ms ago:
  system_server: 1% = 1% user + 0% kernel
  com.android.inputmethod.latin: 0% = 0% user + 0% kernel / faults:
2828 minor
  com.android.phone: 0% = 0% user + 0% kernel / faults: 9 minor
  adbd: 0% = 0% user + 0% kernel / faults: 16 minor
  qemud: 0% = 0% user + 0% kernel
 +sh: 0% = 0% user + 0% kernel
TOTAL: 2% = 1% user + 0% kernel + 0% softirq


but on a 2.2 emulator, the output looks like this:

# dumpsys cpuinfo
dumpsys cpuinfo
Load: 0.0 / 0.02 / 0.07
CPU usage from 111611ms to 51608ms ago:
  system_server: 2% = 1% user + 0% kernel / faults: 3 minor
  zygote: 0% = 0% user + 0% kernel / faults: 1 minor
TOTAL: 2% = 1% user + 0% kernel


i.e. the dashes and DUMP OF SERVICE text are missing,
as well as the softirq percentage in the TOTAL line.

I'll have to look through the code more to see if it's
this or something else in the dumpsys output that causes
DDMS to not show the chart.

In the mean time, at least I now know I can use the
shell and dumpsys cpuinfo to get the same info
(but without the nice chart...)

[android-developers] Re: Cannot get LED notifications to work on my Motorola Droid (with Froyo)

2010-08-27 Thread Brian Swartzfager

Never mind:  I figured out the issue.  Apparently after the 2.1
update, the notification light on the Motorola Droid only blinks when
the screen is blank (http://androidforums.com/motorola-droid/76585-
help-led-notification-light-stopped-working.html).  I never really
noticed the change, but I was able to confirm the fact.  Once the
screen is lit, the notification light goes off.


On Aug 22, 10:08 pm, Brian Swartzfager bcswa...@gmail.com wrote:
 I know others have posted with this general problem, but I've read the
 Android developer page on the topic, as well as several forum and blog
 posts (such

 and no matter what I do, the LED light will not blink.

 I've tried it with DEFAULT_LIGHTS:

 String ns = Context.NOTIFICATION_SERVICE;
 NotificationManager mNotificationManager = (NotificationManager)
 getSystemService(ns);
 int icon = R.drawable.icon;
 CharSequence tickerText = Test 1;
 long when = System.currentTimeMillis();
 ...
 Notification notification = new Notification(icon, tickerText, when);
 notification.defaults |= Notification.DEFAULT_LIGHTS;
 final int HELLO_ID = 1;
 mNotificationManager.notify(HELLO_ID, notification);

 ...and with custom lighting settings:

 String ns = Context.NOTIFICATION_SERVICE;
 NotificationManager mNotificationManager = (NotificationManager)
 getSystemService(ns);
 int icon = R.drawable.icon;
 CharSequence tickerText = Test 2;
 long when = System.currentTimeMillis();
 Notification notification = new Notification(icon, tickerText, when);
 ...
 notification.ledARGB = 0xff00ff00;
 notification.ledOnMS = 300;
 notification.ledOffMS = 1000;
 notification.flags |= Notification.FLAG_SHOW_LIGHTS;
 final int HELLO_ID = 1;
 mNotificationManager.notify(HELLO_ID, notification);

 ...but nothing happens (no error and no light).  I can get the same
 notification to play the default notification sound and to vibrate the
 phone, but the LED simply won't work (and I know the light physically
 works, as I see it flash for email and such).

 I thought perhaps it might be a color issue, but I've tried a few
 color values with no luck.

 I'm pretty much looking for any sort of suggestions, whether they be
 color values worth trying or any sample code from anyone who's
 successfully done LED notifications on a Motorola Droid running 2.1 or
 higher (I noticed one or two posts referenced some sort of bug with
 LED notifications on the Droid but no details were provided).

 I will also mention (in case it's relevant, though I doubt that it is)
 that I am defining a custom layout for my notifications.

 Thanks.

Re: [android-developers] Re: How do you force a reset just like rotation does?

2010-08-27 Thread Shawn Brown

 I have already searched all those links, but was expecting some basic call
 that is generic to every program.

 The call itself is generic, but the arguments have to specify what activity
 you're talking about and only you know that (assuming you're not handling
 some generic intent).

generic?

Can't you use :

Intent(Context packageContext, Class? cls)
Create an intent for a specific component.


So

startActivity(new Intent(this, this.class);

I haven't tested it though.  If this.class doesn't resolve to the
current activity class name, you'll have to figure out a way to get it
there.  I think it'll work.

[android-developers] Bug in Android 2.2 with move to sdcard home screen shortcuts?

2010-08-27 Thread Doug

I've discovered what may be a bug in the app2sd feature of Android
2.2.  I haven't been able to find any information about it using the
usual searches.

My app will create a home screen shortcut in the usual way.  Inside
its intent that to be launched is a few extras describing the action
to take.  One of the extras is a string array.  Now apparently, if
someone creates a shortcut with my app, then moves the app to the
sdcard, Android will strip out the string array intent from the
shortcut.  Other extras are left intact.  This of course renders the
shortcut useless to the app since key data is missing.  Moving the app
back to the phone doesn't restore the missing data.

If the app is already on the sdcard and a shortcut is then created,
it's OK.  But then if the app is moved back to the phone, the string
array extra is stripped again.

I'm just going to take a wild-ass guess and say that Android does
something to an app's shortcuts when it gets moved to and from the
sdcard (maybe re-constructing it?) but it's not copying the string
array extras.  Is there any merit to this guess?  Time to file a bug?

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

2010-08-27 Thread Robert Green

Hey guys,

I doubt there are too many people who run CDT in eclipse for native
apps also with ADT installed for Android, but in the off-chance that
someone here knows anything about this, my problem is that any time I
run any android app, my C builder kicks in for projects totally
unrelated.  I have no idea why and have been digging through settings
on everything, unable to find out why.  All I can think is that the
ADT pre-launch process triggers it via a refresh or some kind of catch-
all type call in eclipse API land that I'm unaware of.

Does anyone know anything about this?  It's very annoying to have a C
builder run for a different project than the one you're working on
every time you launch the app.

Extras are supported but not arrays. You can use String, int, long,
byte, char, boolean, double, float and short. Nothing else will be
persisted, nor is there any plan to support arrays. You can probably
see an exception in logcat logged when Launcher tries to save your
Intent in the database.

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



I would argue the opposite :)

One of the handiest features of Windows Firewall is that you have the 
option of Displaying a notification when it blocks a program, and when 
the dialog shows up, you have the option of granting that program 
access, and then it never bothers you again.


I do agree that the way it was done in Vista was absolutely horrible... 
but a one time Let this program do this works VERY WELL, and I think 
it gets around all the problems you mentioned.


In my opinion, the lack of this is the single most obvious failing in 
Android.

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

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.
