[android-developers] opengl and requestRender update order
Hi, I'm changing a program from standard graphics to opengl. The way that my program behave was: 1. Update internal bitmap information. 2. Draw on the offscreen. 3. Draw the offscreen image on screen. On opengl, i just noticied that anything that you draw before calling requestRender is IGNORED. My idea was to first send opengl commands and then request opengl's surface to draw these. Is there a way to let it work like this? Another way to look at the problem: suppose two threads are updating part of the screen using opengl. How exactly can one thread update the part of the screen that it is drawing, leaving the other part untouched? thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: opengl and requestRender update order
Hi, I'm using GLES20. I'm not sure about how the opengl es 2 works. For me, the requestRender should update the screen with the contents sent by the last opengl commands. However, it seems to do the opposite: start looking for commands and then (at some misterious moment), update the screen. thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: GL_POINTS not drawing points
Hello! Thanks for answering. Actually, i already know how to draw lines and rectangles, but i would like to draw points. Can you provide me with the calls to the Matrix methods that would achieve the 2D projection using screen coordinates for the given surface width and height? I made some tests with just a few points and it looks really strange. For example, if i call this: coords[0] = 10; coords[1] = 10; coords[3] = 11; coords[4] = 10; vertexBuffer.put(coords); vertexBuffer.position(0); GLES20.glVertexAttribPointer(mPositionHandle, 3, GLES20.GL_FLOAT, false, 3 * 2, vertexBuffer); // Prepare the triangle coordinate data GLES20.glDrawArrays(GLES20.GL_POINTS, 0,2); Then i get a point at 0,0 and another at 10,10. If i add a new coordinate at 12,10, i get two points side by side, but if i add a new point at 13,10, i get only 1 point again! thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] using pixel coordinates in opengl es 2
Hi,
I downloaded and played with the opengl sample at
http://developer.android.com/training/graphics/opengl/draw.html
However, it uses the standard coordinate system for opengl, where 0,0
is at the center of the screen and -1,-1 at top-left and 1,1 at bottom-
right.
I want to use the screen's coordinate, where 0,0 is at top-left and
width,height is at bottom-right.
I already tried a dozen things, read about 30 articles, but since i'm
a newbie at opengl, i'm still stumped.
Can someone tell what it has to be done to change the coordinate so
that the given rectangle
static float squareCoords[] = { 10f, 10f, 0.0f, // top left
10f, 20f, 0.0f, // bottom left
20f, 20f, 0.0f, // bottom right
20f, 10f, 0.0f }; // top right
... is shown at screen?
thanks

Hi, So, the permission is written as-is and found only at runtime? I'm asking this because my applications are having problems accessing the sdcard of some tablets like Xoom and Galaxy. From this article: http://www.afternote.net/2012/03/sdcard-write-problem-fix-for-samsung.html , i added these two to my manifest: uses-permission android:name=android.permission.WRITE_MEDIA_STORAGE / uses-permission android:name=android.permission.WRITE_EXTERNAL_STORAGE / and, even with these, i cannot write to the external storage. So, i made a test adding a leading a to a permission to find if android was understanding that permission.

[android-developers] Re: something better than 16bpp
Hi I made a test on a Defy with Android 3.2. The pixel format is 5, 32bpp. In a benchmark program, with 16bpp, i have 6.5s, in 32bpp, i have 7.7s. Also, its clear for me, by looking at the screen colors, that the device is mapping 32 bits to 16 bits, since i can easily see gray shades, which don't appear in my 32bpp windows screen.

Hi, Actually, i'm not sure at all. What i do know is that the Android OS is returning incorrect information.

[android-developers] Cannot start service - yes, this problem again
Hi,
I already searched stackoverflow, this forum and google itself.
Followed all instructions, but i still cannot get my service to be
started at the BOOT_COMPLETED.
The sample i'm using came from
http://marakana.com/forums/android/examples/108.html
This is the service:
package totalcross.appqiri;
...
public class TCService extends Service
{
public IBinder onBind(Intent intent)
{
return null;
}
public void onStart(Intent intent, int startId)
{
super.onStart(intent, startId);
}
public void onCreate()
{
super.onCreate();
}
public int onStartCommand(Intent intent, int flags, int startId)
{
return START_STICKY;
}
public void onDestroy()
{
super.onDestroy();
}
}
This is part of the manifest.xml:
application android:icon=@drawable/icon
android:label=TotalCross Virtual Machine
android:theme=@android:style/Theme.Black.NoTitleBar
activity android:name=.Loader android:label=Loading
application...
android:configChanges=keyboardHidden|orientation|screenLayout|
fontScale|keyboard
android:windowSoftInputMode=adjustResize
/
activity android:name=.WebViewer /
activity android:name=.CameraViewer /
activity android:name=.MapViewer /
uses-library android:name=com.google.android.maps
android:required=false /
service android:name=.TCService android:exported=true /
/application
This is the startup intent that receives the BOOT_COMPLETED:
public class StartupIntentReceiver extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
try
{
AndroidUtils.debug(*** 1);
Class cc =
Class.forName(totalcross.appqiri.TCService);
AndroidUtils.debug(*** 2);
Object o = cc.newInstance();
AndroidUtils.debug(*** 3: +o);
AndroidUtils.debug(*** 4: +context.getPackageName());
Intent i = new Intent(context, cc);
AndroidUtils.debug(*** 5: +i);
Object ret = context.startService(i);
AndroidUtils.debug(*** 6: +ret);
}
catch (Throwable e)
{
AndroidUtils.handleException(e, false);
}
}
}
And, finally, this is the output:
ActivityManager: Start proc totalcross.appqiri for broadcast
totalcross.appqiri/.StartupIntentReceiver:
TotalCross: *** 3: totalcross.appqiri.TCService@404edb18
TotalCross: *** 4: totalcross.appqiri
TotalCross: *** 5: Intent { cmp=totalcross.appqiri/.TCService }
ActivityManager: Unable to start service Intent
{ cmp=totalcross.appqiri/.TCService }: not found
As you can see:
1. The service is inside application in the xml
2. The context' package is the same of the service (line ***3 and
***4)
3. I can load the service using introspection
However, the service cannot be found.
any help is greatly appreciated.
thanks
guich

Ahm The Loader is indeed an activity.

[android-developers] Re: creating a window-close animation effect
Hi, Thanks for the reply. My whole problem is that my application is not a standard one. I don't use xml files; i create all the user interface (which is quite small) by hand. I already tried many things, but no animation is done at all. All i see is the new view appearing at once at the screen. So, i have a current view with a bitmap, then i update the bitmap natively, then i want to show the new bitmap appearing at the top of the other one. thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: creating a window-close animation effect
Hi Mark, Unfortunately, that's not an option. I don't create programs for Android, i create a virtual machine that runs side by side with Dalvik. All i need from Android is to start the program, handle pen and keyboard events, and show the contents drawn by my VM on the screen. Too bad that this can't be done fully in native mode, like in iOS, Windows Mobile and (dead) Palm OS. Anyway, i got some evolution by calling the runOnUiThread method. I can start the animation, i can see it has stopped, but nothing happens on screen. I'm pretty sure its because of my very small knowledge about the Android UI stuff (as i said, i use very few of the UI). This is the situation: 1. I have a SurfaceView that calls a native code that draws on a bitmap. The native code then asks the screen to be repainted. 2. Sometimes, the native code may ask to paint it with some effects, like a transition between screens. So, it fills the offscreen bitmap and asks dalvik to show it on screen with some effect. I searched the net to find if there's a way to let a bitmap be applied over another bitmap with animation, but found nothing. So, i realized that a view can be shown on the top of another view with animation. The idea is to write to the offscreen bitmap, create an ImageView, draw the bitmap on it, and apply the animation transition from the SurfaceView to the ImageView. So, I tried this code: 1 if (iview == null) 2iview = new ImageView(instance.getContext()); 3 iview.setImageBitmap(sScreenBitmap); 4 ScaleAnimation anim = trans == TRANSITION_CLOSE ? new ScaleAnimation(1f,1f,0f,0f) : new ScaleAnimation(0f,0f,1f,1f); 5 anim.setDuration(2000); 6 anim.setAnimationListener(this); 7 iview.setVisibility(ImageView.VISIBLE); 8 instance.startAnimation(anim); I already tried iview.startAnimation, but nothing occurs visually. Any help is appreciated. thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: creating a window-close animation effect
I got one of the animations working: the old view is visible, then a new view grows from center to the border. However, in the opposite situation, i'm unable to get the desired results: i want that the old view be shrinking while the new view appears. Not sure if i was understood: is like if the new view is behind the old view, which shrinks from the border to center. What happens is that the old view appears on the top of the new view, instead of the desired situation, where the new view is behind the old view.

I'm still searching. I found that with the ScaleAnimator i can achieve what i need, but still trying with no success.

This image is updated by a native function. ImageView image = new ImageView(instance.getContext()); image.setImageBitmap(sScreenBitmap); image.setVisibility(ImageView.VISIBLE); image.startAnimation(anim); This is called from another view.

[android-developers] resintalling application due to data corruption
Hi, Some users are having a very serious problem with some android devices (motorola, samsung): after running the application for several hours, some data files are being corrupted by the OS. The most strangest thing is that these files are opened using fopen(.., rb), thus, in read-only mode. They are never written from our code. I can easily detect that the corruption occured when the program starts. I was thinking, in this case, to call the installer again. I know that the installer are stored at /data/app/*.apk. Is it possible to call the installer from the application in a non-rooted android device or is this blocked? thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi Dianne, Lemme explain my problem. All my application is drawn in an offscreen bitmap. When the application starts, i get the maximum width/height of the screen and create a square bitmap. This way, when screen rotates, i don't have to create another bitmap. This prevents some crashes in my application. I'm aware of the bug fix, i saw your comments in another thread. What i'm asking is if Google can create a way to retrieve the size with something like this: public Size getSizeOfScreenIncludingTaskbarArea() or public Size getSizeOfScreenForOrientation(int orientation) // VERTICAL or HORIZONTAL This would help a lot. thanks for your time.

[android-developers] display.getWidth bug fixed in android 3.2
Hi, There's a change in Android 3.2 that made the following code stop to work as expected: WindowManager wm = (WindowManager)instance.getContext().getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); int screenHeight = display.getHeight(); Prior to 3.2, the width/height informed included the task bar. Then, in 3.2, it EXCLUDES THE TASKBAR. Its mandatory for my application to know in advance the value of the screen WITHOUT THE TASKBAR.

Hi, I'm searching already for a couple of hours and was unable to find a simple sample that shows how to open MapView with an address, like, the bull at wallstreet. I know i have to use location.Address class, but it has several parameters and i just don't know set them. Can someone provide me a sample that open a MapView and shows the bull at wallstreet location? Or even just how o get the bull (wallstreet, new york, usa) coordinates. many thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] how to detect an invalid pin was given by the user when connecting to bluetooth
Hi, I'm implementing bluetooth support for my application. When i try to connect to the device, Android shows me the dialog that asks for the pin. Now i have two questions: 1. How to detect that the dialog was closed? The user could press cancel, and i need to detect this 2. How to detect that the password was wrong? I realized during the tests that if the user enters a wrong password, i receive an IOException with unable to find services (or something like this). If the pin is correct, this exception is not thrown. Isn't there a better way? Also, even if a wrong password is given, the device is added to the BONDED list, and can be retrieved with the BluetoothAdapter.getBondedDevices. I'm using an Android 2.2.1 device and a Zebra printer with bluetooth 2.0 specification.

[android-developers] Connecting to a Zebra MZ 320 over bluetooth - without PIN
Hi, I'm trying to connect an Android with such printer. The printer has this information retrieved by BluetoothClass: Class: 1664/1536: Render What (BluetoothClass.Service.)Render means? Is there a specific UUID for it? I tried to connect to the device using the well known SPP UUID, however, Android keeps asking me for a PIN. The printer, with BT 2.0, has authentication mode turned off. I read in some places that Android requires a PIN to pair with a device. I tried and 1234 as suggested by the pairing dialog but the connection fails. Isn't really a way to pair without setting a PIN? Otherwise, i'll have to connect all 300 printers to a pc just to set a PIN so Android can connect to it. thanks in advance, guich www.totalcross.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

I was able to print by changing the printer to have a PIN. However, doing this in 300 devices will be a headache. :-( guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Strange effects on Android's truetype decoder
Hi,
If you call Paint.setTextSize and set it to a wide range, like 7 to
40, you will note that the transition is not smooth. Sometimes it
repeats the same height.
The code below illustrates what i mean (testing on an emulator for
android 2.2):
Paint paint = new Paint();
paint.setAntiAlias(antialiased);
paint.setTypeface(Typeface.SERIF);
paint.setColor(Color.BLACK);
Rect r = new Rect();
for (int i = 7; i 40; i++)
{
paint.setTextSize(i);
paint.getTextBounds(Ãg_,0,3,r);
maxH = (int)(Math.abs(paint.descent()) +
Math.abs(paint.ascent()));
int realH = Math.abs(r.top - r.bottom);
println(size: +i+, height: +maxH+, realH: +realH);
}
And the output is:
size: 7, height: 8, realH: 9
size: 8, height: 9, realH: 10
size: 9, height: 10, realH: 10
size: 10, height: 11, realH: 13
size: 11, height: 12, realH: 13
size: 12, height: 13, realH: 15
size: 13, height: 15, realH: 15
size: 14, height: 16, realH: 17
size: 15, height: 17, realH: 17
size: 16, height: 18, realH: 19
size: 17, height: 19, realH: 19
size: 18, height: 20, realH: 20
size: 19, height: 22, realH: 23
size: 20, height: 23, realH: 23
size: 21, height: 24, realH: 26
size: 22, height: 25, realH: 26
size: 23, height: 26, realH: 28
size: 24, height: 27, realH: 28
size: 25, height: 29, realH: 29
size: 26, height: 30, realH: 29
size: 27, height: 31, realH: 32
size: 28, height: 32, realH: 32
size: 29, height: 33, realH: 33
size: 30, height: 34, realH: 35
size: 31, height: 36, realH: 35
size: 32, height: 37, realH: 38
size: 33, height: 38, realH: 38
size: 34, height: 39, realH: 40
size: 35, height: 40, realH: 40
size: 36, height: 41, realH: 42
size: 37, height: 43, realH: 42
size: 38, height: 44, realH: 44
size: 39, height: 45, realH: 44
Am I missing something? Why the gaps between the font sizes and the
heights? For example, size=30-31 has size 34-36. How can i achieve
height 35?
Even if i use a smaller increment for i, like 0.1 or 0.01, i don't
actually get a smooth scale for the font.
thanks
guich

[android-developers] How to find available services in a bluetooth connected device
Hi, I'm trying to establish a connection between an Android device and a cell phone (this is my first test, in the real world, i'll be connecting to any device, like a printer). I was already able to discover the device, and now i'm trying to connect to it. However, i didn't find in the android API a way to retrieve the services available and their UUIDs, so i can communicate to each one separately. Is there a way to do this on Android? Just as a simple test i tried to use the SPP UUID but it failed to connect (yes, all devices have bt on and are discoverable).

[android-developers] TIP: An approach for creating backward-compatible classes
Hi,
I'm implementing Bluetooth support on my application, which is
compatible with Android 1.6 (and must remain since in Brazil we still
have those devices running out).
By reading this article:
http://developer.android.com/resources/articles/backward-compatibility.html
I found an easy way that allow you to create classes that can be used
in new and old devices.
The idea is the creation of a DUMB class, that would work in devices
that are not compatible, and an IMPLementation class that extends the
DUMB class and would work on devices that are compatible.
So, this is the dumb class:
public class Level5
{
public static Level5 instance = android.os.Build.VERSION.SDK_INT =
5 ? new Level5Impl() : new Level5();
public boolean btIsSupported()
{
return false;
}
}
And here the implementation class:
public class Level5Impl extends Level5
{
public boolean btIsSupported()
{
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
return bluetoothAdapter != null;
}
}
Then, you can call:
Level5.instance.btIsSupported();
All public fields that are used inside Level5Impl must be declared
inside Level5, and all public methods must be declared in Level5 too,
so they are overriden in Level5Impl.
Hope this helps,
Guilherme C. Hazan (guich)

[android-developers] black camera jpeg on Defy
Hi,
I have a code that works fine in all Android devices i tested (over
10), but fails on a Defy. The resulting jpeg file is just a set of
black pixels (all image is black).
Here's a piece of code:
pre
class Preview extends SurfaceView implements SurfaceHolder.Callback
{
Preview(Context context)
{
super(context);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
// Install a SurfaceHolder.Callback so we get notified when
the
// underlying surface is created and destroyed.
holder = getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
// Called once the holder is ready
public void surfaceCreated(SurfaceHolder holder)
{
startPreview();
}
// Called when the holder is destroyed
public void surfaceDestroyed(SurfaceHolder holder)
{
stopPreview();
}
// Called when holder has changed
public void surfaceChanged(SurfaceHolder holder, int format, int
w, int h)
{
if (camera != null)
{
Camera.Parameters parameters=camera.getParameters();
parameters.setPictureFormat(PixelFormat.JPEG);
camera.setParameters(parameters);
camera.startPreview();
}
}
}
private void startPreview()
{
if (camera == null)
try
{
// The Surface has been created, acquire the camera and
tell it where to draw.
camera = Camera.open();
camera.setPreviewDisplay(holder);
}
catch (Exception e)
{
AndroidUtils.handleException(e,false);
}
}
private void stopPreview()
{
if (camera != null)
{
try {camera.stopPreview();} catch (Exception e) {}
try {camera.release();} catch (Exception e) {}
camera = null;
}
}
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
preview = new Preview(this);
((FrameLayout) findViewById(R.id.preview)).addView(preview);
final Button buttonClick = (Button)
findViewById(R.id.buttonClick);
buttonClick.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
try
{
camera.takePicture(null, null, jpegCallback);
}
catch (Exception e)
{
AndroidUtils.handleException(e,false);
stopPreview();
setResult(RESULT_CANCELED);
finish();
}
}
});
// Handles data for jpeg picture
PictureCallback jpegCallback = new PictureCallback()
{
public void onPictureTaken(byte[] data, Camera camera)
{
try
{
FileOutputStream outStream = new
FileOutputStream(fileName);
outStream.write(data);
outStream.close();
setResult(RESULT_OK);
finish();
}
catch (Exception e)
{
AndroidUtils.handleException(e,false);
}
}
};
/pre
I checked the adb logcat output but no errors were displayed. Also, i
checked if the onPictureTaken was called more than once, but it was
not (only one call).
Any help is appreciated.
TIA
