[android-developers] Alpha Buffer support on G1
Since Google groups doesn't let you add posts to threads more than 60 days old, and I want to leave a solution to the problem I encountered a while back, I'm posting this message with the same title in hopes that anyone running into the problem I had will find this message as well. I was having trouble getting my G1 to render an RGBA_ OpenGL context to the screen. Everything was twice the size it should be because the pixels were being interpreted as two 565 pixels. The colors were obviously wrong as well. I had missed a critical function call. You must configure the Surface that is being used by EGL using the SurfaceHolder method setFormat. The pixel format needs to be TRANSLUCENT, or more specifically you can use RGBA_. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Oh sure, if you are going to do some longer-running -continuous- work then use a service. Don't use a service to sit there and do nothing but schedule future work (which is what you seemed to be describing in your first post). The widget example on the developer blog uses a service as well, but > does not call Service.stopSelf() when done. Hm. Bad sample code! No cookie! I'll see about getting that fixed. In the meantime, consider stopping a service when it is done with its work to be a Good Thing. :} -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

You need to ask your carrier to provide the maps binaries in their system images (or did you create your own system images?) The SDK only helps you develop application that run with whatever API a given device has. Maps is not part of the "core" Android platform, it is part of the "Google Experience" devices with combine the Android system with a set of Google-specific applications. The SDK will not magically make these apps appear on a given device. Only a carrier can decide that. So the bottom line is: does your device have Maps on them?

Ubuntu 9.04 already has a rules/50-something file so you need to make

No, what you are supposed to do, is not return from onCreate until you are ready to show your GUI. I am not ready without these items. If it took, say, 2 or 3 seconds to load these items, maybe, but it takes a fraction of a second - the screen flashes 'LOADING' and then shows the items. It looks quite ugly.

If I do this, then I lose the benefits of running it in the UI thread.
I want to hang my application until it gets these items, because if
not, my view with id="android:empty" shows up for a second, and that
looks ugly.

The data is inside a List inside my service, already pre-made. It
should take basically no time at all.
How would I fix the deadlock?

Icky!
Move the "now retrieve from service using binder and set list adapter"
into onServiceConnected() and get rid of the sleep() infinite loop.

Is your service positively deterministic, such that it will *always*
take less than a second? Or does it take less than a second only in
normal conditions (e.g., connectivity is OK to some server you're
fetching data from)?

By default, yes. There are other ways of dealing with this.
> But, if I run it in a separate thread, it will not.
Sure it can. Either don't reload the state from the service (by using
onRetainNonConfigurationInstance() and having your state persist across
rotations), or fork another background thread (if these are
load-data-and-close threads), or tell a persistent background thread
"yo! load the stuff again!".

Correct.

Equally correct.

Spot on! In other words, icky!
> Sorry for such a long question,
I seem to have missed the question.
If the question is "how do I get rid of the infinite loop?", move the
"now retrieve from service using binder and set list adapter" into
onServiceConnected().
However, unless you're really really certain this will always occur very
very quickly, use a background thread, in addition to getting rid of the
infinite loop.

[android-developers] Android Loading listview items from service results in hang
Hello,
In my Android application, I have a ListActivity. This ListActivity
uses a SimpleAdapter that I fill with items from my service. So, in my
code, I do:
MySuperCoolService.Binder serviceBinder = null;
private ServiceConnection serviceConnection = new ServiceConnection()
{
public void onServiceConnected(ComponentName className,
IBinder service) {
Log.d(TAG, "Service connection: connected!");
serviceBinder = (MySuperCoolService.Binder)service;
}
public void onServiceDisconnected(ComponentName className) {
Log.d(TAG, "Service connection: disconnected");
serviceBinder = null;
}
};
bindService(new Intent(this, MySuperCoolService.class),
serviceConnection, BIND_AUTO_CREATE);
while(serviceBinder==null) {
Thread.Sleep(1000);
}
// now retrieve from service using binder and set list adapter
This whole operation takes hardly any time (less than a second), so I
want it to run in the UI thread. See my onCreate:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fillDataUsingCodeAbove();
}
The reason I want this to run in the UI thread is that if you have a
list item selected, or you have scrolled to a certain position in the
ListView, and you rotate the device or take out the keyboard or
something (to trigger a configuration change) when my activity is
restarted, Android will try to restore the state right after onCreate.
But, if I run it in a separate thread, it will not. Also there is a
cool fadein animation too :)
The problem I am having with running it in the UI thread is that when
I try to bind to the service, that service bind request gets put onto
the message queue. But then when I go into my loop, I stop the message
queue from looping. So my program hangs, because it's waiting for the
service to get bound, and the service won't get bound until the loop
ends (I think you call this a deadlock). I have thought of putting
Looper.loop() inside my loop, but that just hangs it at Looper.loop()
(I don't know why.)
Sorry for such a long question,
Isaac Waller

[android-developers] Re: get color from ImageView (x/y)?
You can do something like this:
public class MyImageView extends ImageView {
.
.
.
public boolean onTouchEvent(MotionEvent ev) {
BitmapDrawable bd = (BitmapDrawable)getDrawable();
Bitmap bitmap = bd.getBitmap();
int color = bitmap.getPixel((int)ev.getX(), (int)ev.getY());
// red --> Color.red(color)
// green --> Color.green(color)
// blue --> Color.blue(color)
return true;
}

[android-developers] Widget process lifetime: Why not stop the service?
I'm writing a widget that needs to update rather infrequently (say multiple hours). Following the source examples out there, it seems the common solution is to use a service to prepare the updates. However, after I am done, my process is still running on "service level", it looks like it's not being killed by Android in low memory conditions, and killing it manually causes it to restart. The same seems to be true for all other widgets I have installed so far - they stay in memory. Wouldn't it be better to have to service call this.stop() when it is done, at least if the widget knows it probably won't need to do another update any time soon? I'm doing this now, and it seem to work fine - my process is being killed when Android needs memory.

Use AlarmManager to broadcast an Intent at the time you want to do some work and have the device wake up.

[android-developers] Re: Unable to remove default launching of an application.
For a quick example, download Astro File Manager, click on a image file, you should see 2 actions: * ASTRO Image Viewer * View Picture (standard) And a check box "Use by default for this action", I choosed "View Picture". If you check it, a text explains (ok it does not "tell", don't play on words...) : "Clear default in Home Settings > Applications > Manage applications. If you go there, then click on Astro: the Clear defaults button is disabled. But I eventually realized that I misunderstood the feature, we have to clear the default launching in the choosed application, not the triggering one, e.g. Camera in my example... But my second question remains unsolved: there is an interesting flag in the Manifest: android:allowClearUserDataWhether or not users are given the option to remove user data — "true" if they are, and "false" if not. If the value is " true", as it is by default, the application manager includes an option that allows users to clear the data. It's enabled by default. Turning it to false (or explicitly to true) seems to have no effect at all. The application controls I have for any Market/Eclipse apps are: * Uninstall * Clear cache (what cache ? web cache ?) * Clear defaults (ok now) * Force stop In the built-in applications I have also an extra "Clear data" button. How to make this button appear for my app ? Is that "allowClearUserData" is supposed to do ? In this case there is a bug or a nasty limitation. 2009/5/23 Mark Murphy > > > I have the same bug for all non standard applications, whatever the > > phone I tested. > > What's going on with this feature ? > > It is difficult to answer this question, since you have not really said > what the "feature" is you are curious about. > > >> > I check the box, it tells me that I can clear the setting in > >> > Application -> Manage Applications. > > From your original post, my guess is that this is where you are starting > to encounter what you feel is unusual behavior.
