Re: [android-developers] Re: LoaderCallbacks.onLoadFinished unnecessarily called twice when rotating
There's a fair discussion on StackOverflow here: http://stackoverflow.com/questions/11293441/android-loadercallbacks-onloadfinished-called-twice/22183247 I saw the behavior when re-loading a Fragment in a ViewPager, which may be very similar to rotation... Basically, I solved the problem by removing the loader when I was done with it: getLoaderManager().destroyLoader(LOADER_ID); On Monday, July 2, 2012 4:49:50 PM UTC-4, Malcolm Evershed wrote: Your issue sounds like it could be different than mine since I'm generally seeing onLoadFinished() called in initLoader(). You might want to do more web or StackOverflow searching or search the Android bug database -- I think somewhere I read about a problem where onLoadFinished() would not be called, but I think it only happens if you don't do the stuff that CursorLoader does. In other words, to solve your issue, you might have to copy a bunch of code from CursorLoader. As to my issue, I never reported it since there didn't seem to be any interest in it.

listeners for most events (like video stopped or ended).

If yes how?

[android-developers] Re: bitmap magnification
I would advise calculating the scale of original image to screen
height/width, and adjusting your inSampleSize accordingly. When it's
2, you're always loading half of the source bitmap, so if it's huge,
you're still loading half of huge. You'll want to do something like
options.inSampleSize = srcWidth/screenWidth;
(maybe different, depending on your ratio, and if you want to fill the
screen, etc. You might also want to round inSampleSize to the nearest
power of 2.

It depends on what type of audio you want to play... If you're playing

That sounds most likely (bug in platform). I've only been able to reproduce it on 1.5 and 1.6, not 2.0 or 2.1... So I guess that returns me to my original question: Is there any way I can detect this state in my code (I guess I don't mind polling when viewing this Activity). If so, what's the right thing to do? Is there a way to release the lock? Can I just kill the app? I guess the main goal is to avoid timing out and show the wait/ force close message in this case. Thanks.

My guess is the video isn't the right size, so the device is struggling to scale the video and/or the bitrate is just too high... Try a lower bitrate, and check the dimensions of your video.

[android-developers] Re: Touch event noisy
I'm not positive, but maybe the issue is that you're getting touch events for each time you draw your scene? Try to skip drawing, and just print debug about when your finger is down... I think that will shed some light on the issue. You could also just capture the touchdown, record it's startTime, and if you haven't received an event in some delta (probably like 50ms?) assume you should stop the character. Good Luck.

I'm working on a simple game: when you press a button on the screen, a character will run to certain direction. it's easy to support keyboard input. but, some phone doesn't go with a keyboard or even no a track ball. so I decided to draw a virtual run key on the screen (with opengl). when the user press the virtual key, i apply a velocity to the character. and when the user release the key, i disable the velocity to stop the character. but there seems to be some touch event noisy. if my finger cannot press still, i will see millions of touch down and touch up events, instead of a single long pressing. and occasionally, my program captured the touch down event when i touch the screen, but didn't capture touch up event. so my character will keep moving, even no finger is on the screen. I'm wondering if there is some way to reduce the touch event noisy and tell if the user is currently pressing on the screen, instead of only getting an event when touch up and down happen. it seems the system ui can detect long pressing, for example when you put a finger on one item of the list view widget, the entire item turns to orange. i just don't know how to detect pressing in my opengl game. thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

I'm not sure why you can't just use a thread (no handler)?
If you do need a handler, you can just create a new runnable, and post
it to the handler with something like:
new Handler().post(new Runnable(){
public void run(){
image = new GLCamTest().extractimage(q);
}
});

doing with calls? Maybe you can get away with turning off/disabling
all radios? (I don't know how feasible this is).
Maybe you just want to block the notifications, and not the actual
messages?

Hello,
I want to block incoming and outgoing Text (as well as email). I am using
the broadcast receiver that is not blocking the text but its blocking the
outgoing calls. Can some one help me. Thank you.
Here is the piece of code that blocks the SMS.
-
public void onReceive(Context context, Intent intent)
{
mContext=this;
String actionType = intent.getAction();
if ((actionType.equals(Intent.ACTION_SEND)))
{
setResultData(null); // I tried
with abortBroadcast(); this didn't work either
}
}

[android-developers] Re: drawing lines on top of a image view
If you want to draw on top of an ImageView, I would extend it and override it's onDraw method. This provides you a [relative] canvas to draw on. Just be sure to call super.onDraw() if you want the image to show up also. On Jul 13, 11:23 am, Jags jag...@gmail.com wrote: I am trying to put a background image and draw on top of that screen.

[android-developers] Re: OpenGL texture wrapping flickers. Why?
I was able to solve this... I was calling the texture wrapping code on every draw, right before I bound the texture. Now, I set the texture parameters when the textures are generated, and I don't need to specify wrapping every time I draw a shape... No more flicker, and the code is probably more efficient. -- You received this message because you are subscribed to the Google Groups Android Developers group.

I found the solution here: http://groups.google.com/group/android-developers/browse_thread/thread/2de77043f32835aa/f2a1357bf1335461 It's basically: Add the following to your activity: getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] OpenGL texture wrapping flickers. Why?
I'm drawing 5 rectangles with OpenGL. They are texture mapped, and use the following parameters/binding: ... gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[textureid]); ... I then draw them like this: ... gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, smallTexBuffer); gl.glDrawElements(GL10.GL_TRIANGLE_FAN, VERTS, GL10.GL_UNSIGNED_SHORT, mIndexBuffer); ... When I start the activity, the shapes all flash as if the textures were supposed to wrap (ie, i see more than one texture per shape), then the screen quickly corrects itself. Is there some manual buffering I'm supposed to do while the textures get mapped and unwrapped? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Theme.NoTitleBar.Fullscreen not working when other activities use a custom title?
My test involves 2 Activities, one with a GridView, and one with a ListView. The GridView is defined as Theme.NoTitleBar.Fullscreen and works great on first launch. The ListView defines a custom title bar using: getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar); The app starts and you are presented with a GridView. For simplicity I added one item: http://picasaweb.google.com/lh/photo/twm8eQBvUAQcajNr5Z5RRQ?feat=directlink If you click the item you go to a ListView: http://picasaweb.google.com/lh/photo/sFI7SNMjIC0iXjmxQVqKLg?feat=directlink Now when I click back I'm back at the first Activity. If I press up on the dpad I can scroll up: http://picasaweb.google.com/lh/photo/eRx06OVXFtPccmtgT_b0pw?feat=directlink Is this because of the custom title? Can anyone give me advice to avoid this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Smooth Image Rotation with Gesture Control?
You should be able to override onDraw, and draw the bitmap using something like: canvas.drawBitmap(bitmap, matrix, paint) I haven't used drawBitmap with a matrix before, but you can check out some more info here: http://www.anddev.org/resize_and_rotate_image_-_example-t621.html You should be able to use a GestureDetector to control when it spins, etc. It might be easier to do this in OpenGL, but I think it's definitely possible with just Canvas if you're not familiar with OpenGL.

[android-developers] Re: organizing the code
Well, as far as I can tell, the only error-handling you're doing in
that whole block is to set picvalues to an empty object if you get a
JSONException... If all you're going to do on Exception is log a
message, there's probably no reason to call out each Exception
seperately. You can Log each step that might throw, and wrap the
whole method in a try/catch. You'll still be able to pull out
specific types of Exceptions if you need to... Maybe something like
this:
public void something() {
try {
nameValuePairs.add(new BasicNameValuePair(id, picId));
InputStream content = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(
http://www.pedroteixeira.org/thennnow/alg_showpopup.php;);
httpPost.setEntity(new
UrlEncodedFormEntity(nameValuePairs));
response = httpclient.execute(httpPost);
content = response.getEntity().getContent();
StringBuilder sb = new StringBuilder();
String line;
BufferedReader reader;
reader = new BufferedReader(new
InputStreamReader(content,
UTF-8));
while ((line = reader.readLine()) != null) {
sb.append(line);
String pic_values = sb.toString();
try {
picvalues = new JSONArray(pic_values);
} catch (JSONException e) {
// TODO Auto-generated catch block
picvalues = new JSONArray(); // just
so it's not null.
}
}
} catch (JSONException je) {
picvalues = new JSONArray();
} catch (Exception e) {
Log.d(TAG, Exception: + e);
}
}
