[android-developers] debugging with a different keystore
Hi, I know that, to be able to sign a package with your own keystore, you have to use the export from eclipse. However, its not easy to keep doing this when you're still debugging the application. Since i have external libraries that uses another keystore and use the shareUserId, it would be reasonable to let, in eclipse plugin, you debug an application using any keystore. Any tips of how to make debugging easy with a private keystore? thx guich -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] changing the background color of an activity
Hi, When i launch Activity A, the screen goes black, then dark-gray. Then A launches B, and the screen goes black and dark-gray again. Is there a way to set the default background color to black?

[android-developers] Re: OpenGL poor performance with textures?
Hi Federico,
I tried during weeks to get a working code for the opengles. The idea
was to draw an offscreen bitmap into the screen (i do all the graphics
rendering by myself). Then someone told me that using textures for
this was not a good idea, because it takes time to make the texture
get into the video card and then displayed.
Since my knowledge of opengl is near 0, i gave up and used the
SurfaceView approach. I also published the code here:
This goes at surfaceChanged:
sScreenBuff = ShortBuffer.allocate(w * h);
sScreenBitmap = Bitmap.createBitmap(w, h,
Bitmap.Config.RGB_565);
And this is my updateScreen method:
static void updateScreen()
{
try
{
if (sScreenBitmap == null)
return;
Canvas canvas = surfHolder.lockCanvas();
if (canvas == null)
return;
instance.nativeOnDraw(sPixels); // call Native C code
sScreenBuff.put(sPixels);
sScreenBuff.rewind();
sScreenBitmap.copyPixelsFromBuffer(sScreenBuff);
canvas.drawBitmap(sScreenBitmap, 0, 0, null);
surfHolder.unlockCanvasAndPost(canvas);
}
catch (Throwable t)
{
debug(Log.getStackTraceString(t));
}
}
Have you done something different to achieve the 60fps?
Btw, i can test your code in two devices, the G2 Ion and the Motorola
Milestone (A853).
thanks and regards,
guich

[android-developers] changing the default theme of an intent that is being launched
Hi Folks, I have activity A that calls intent B. The user may set A to full screen, so currently i pass a parameter to B (which, by default, is NOT fullscreen) in order to make it fullscreen. This works fine, except that the top bar disappears, appears and then disappears again.

[android-developers] getting the serial number
Hi, Yes, i know this was already often asked, but no one ever posted the solution. Seems that the "android id" is NOT the serial number, because it requires you to access the Market before it is assigned. The serial number is displayed when you type: > adb devices The number displayed **is** the serial number of the device. I could confirm that because the same number that appears in the adb list is written behind the battery as "S/N". Does someone know how to get access to that number in the device?

Hey, thanks
Worked fine on G2. This is the code i used:
#include "sys/system_properties.h"
char buf[32];
buf[0] = 0;
__system_property_get("ro.serialno",buf);
Interestingly enough, i also tried this:
char buf[2048];
if ((in = open("/proc/cpuinfo", O_RDONLY)) < 0)
debug("can't open"); // 2mb at least, or some litebase tests
will just skip over.
else
{
if (read(in, buf, sizeof(buf)) < 4)
debug("can't read");
else
close(in);
and it outputs:
can't read

[android-developers] Modal Dialogs: the definitive solution
Hi,
I decided to share the solution i found to the problem of Android not
supporting real modal dialogs.
The solution was to draw the dialog by myself. :-( Well, at least
worked fine, besides the problem that its a bit ugly. :-)
Here's the code i used:
static boolean alertShowing;
public static void alert(String msg)
{
int scrW=instance.getWidth(),scrH=instance.getHeight();
alertShowing = true;
final int fh = 18;
// note: we have to draw the dialog on screen, otherwise if we
use Dialog, the application just quits
String[] msgs = msg.split("\n");
Canvas canvas = surfHolder.lockCanvas();
// fill with white
Paint p = new Paint();
p.setColor(0x);
canvas.drawRect(0,0,scrW,scrH,p);
p.setColor(0xFFAA);
int ly = fh+fh/2;
canvas.drawRect(0,0,scrW,ly,p);
// draw caption in black
p.setColor(0xFF00);
p.setStyle(Paint.Style.STROKE);
canvas.drawRect(0,0,scrW-1,scrH-1,p);
p.setAntiAlias(true);
p.setTextSize(fh);
p.setTypeface(Typeface.DEFAULT_BOLD);
p.setTextAlign(Paint.Align.CENTER);
canvas.drawText("ALERT",scrW/2,fh+fh/4,p);
canvas.drawLine(0,ly,scrW,ly,p);
// draw message
int maxy = scrH-fh*2;
p.setTypeface(Typeface.DEFAULT);
for (int i =0,y=fh*3; i < msgs.length && y < maxy; i++, y += fh
+2)
canvas.drawText(msgs[i], scrW/2, y,p);
String ok = "Ok";
int tx = scrW/2;
int ty = maxy+ly;
canvas.drawText(ok,tx,ty,p);
Rect bounds = new Rect();
p.getTextBounds(ok, 0, ok.length(), bounds);
int ww = bounds.width();
int hh = bounds.height();
canvas.drawRect(tx-ww,ty-hh-3,tx+ww,ty+3,p);
surfHolder.unlockCanvasAndPost(canvas);
while (alertShowing)
try {Thread.sleep(200);} catch (Exception e) {}
}
public boolean onTouchEvent(MotionEvent event)
{
if (alertShowing)
{
alertShowing = false;
return true;
}
}

[android-developers] rebooting programatically / platform certificate
Hi,
I read that, to be able to reboot programatically, you have to:
1. Sign your app with the "platform certificate"
2. Do this:
Intent i = new Intent(Intent.ACTION_REBOOT);
i.putExtra("nowait", 1);
i.putExtra("interval", 1);
i.putExtra("window", 0);
sendBroadcast(i);
Questions: can any app be signed with such certificate? Can we install
it in non-development devices? Can such app be published in the
market?
In case the answer is NO, i'll like to propose Android developers to
let the app issue this and then the system would ask the user "do you
want to reboot?". This would make us happy.
thanks

[android-developers] problems using SCREEN_DIM_WAKE_LOCK

I'm trying to programatically turn the screen off and on, while keep

If i try this code:
final PowerManager pm = (PowerManager)
loader.getSystemService(Context.POWER_SERVICE);
AndroidUtils.debug("creating lock");
screenLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK,
"TotalCross");
AndroidUtils.debug("lock: "+screenLock);
screenLock.acquire();
AndroidUtils.debug("acquired: "+screenLock);
... then the application stops at the "acquire" method call
("acquired" is never printed).
If i change to:
PowerManager pm = (PowerManager)
loader.getApplication().getSystemService(Context.POWER_SERVICE);
(note the getApplication()), then i get:
java.lang.SecurityException: Neither user 10030 nor current process

Hi, I'm now trying to change the current date and time of the device.

[android-developers] Re: Modal Dialogs: the definitive solution
My application is not a standard application. Is a virtual machine.
This is the schema:
totalcross application <-> totalcross vm <-> native code <-> dalvik vm
<-> totalcross' android classes
When the TotalCross application calls Vm.alert("hi!"), it is expecting
that the call will resume ONLY after the alert is closed.
I didn't find another way to do this.

[android-developers] java.io.Exception in AssetManager.readAsset (Android BUG)
Hi, This is a new thread about an old bug. There's a bug in the AssetManager that, if you try to read using a byte buffer a raw resource bigger than 512k (in G2), it will throw this exception: java.io.IOException at android.content.res.AssetManager.readAsset(Native Method) at android.content.res.AssetManager.access$800(AssetManager.java: 36) at android.content.res.AssetManager $AssetInputStream.read(AssetManager.java:542) If you call is.read(), reading one byte per time, it WORKS. However, for a 6MB file, it takes just too long reading 6 million bytes. Questions: 1. Was this bug already fixed in later android devices? My G2 is 1.6. 2. Are there any *usable* workaround for it? 3. Is there a way to access the raw resource from C? thanks guich -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] how much time we have at onPause until we are killed?
Hi, When the user press the home key, the onPause method is called. At this time, the application is supposed to save its state so it can be properly recovered later. However, and if the state is taking too much time? For example, issuing a closeAllNetworkConnections that was waiting a feedback from the server, or just if the amount of information we're writting to disk is a lot of info... what would happen? In my tests, i'm getting from 300-500 ms of time until the process is killed.

Hi, When i first launch my main intent, i check if the application was updated and, if yes, i decompress some asset files. This task can take up to 15 seconds (to decompress a 6MB zip file).

Hi Mark, Thanks for the information. What i was thinking to do was to write a service that was automatically started and just keep running in the background, even with no other intents alive. So, it would be a service-only application; no user interface at all. It would run and, from time to time, connect to a server, download data, and sleep again. guich -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: services x threads
Hi, I already read the diamonds article. The problem here is that the Android team forgot that some phones will be of exclusive dedication to some programs. For example, there are many Sales Force programs that will allow only itself to run in the phone. To these programs, the idea of NOT intercepting the HOME key is unacceptable. This may lead these users to abandon Android in favor of platforms that allow that (like windows mobile, palm, blackberry). An idea behind the service was to let the app keep polling the data server from time to time, in the background. Actually, this can also be done by using server socket, so the service would just sit and listen for a server connection. Almost no processing at all. I think that Android is a great platforms, however, it has some bugs that must be fixed. The dont_intercept_the_home_key is one, the kill_the_app_when_turning_off is another, the dialog_that_appears_asking_to_unblock_the_phone is another issue, and finally, the no_real_modal_messageboxes. I also undertand that Android apps has a specific lifecycle, however, for SF applications, this is really a no-go. regards guich -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[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:
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);
}
}
};
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

[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.

[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.

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.

[android-developers] officially supporting dual-sims
Hi, There are lots of dual-sims phones being dropped at the market and Android has no official support for them. Will this be added in the near future to the android api?

[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
guich

[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] 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. May i ask PLEASE to Android developers to add an API in a future version of Android to get the size as before? Currently, i have to check if its android 3.2 and force a screen rotation, get the size in both directions, then cache this value.

[android-developers] Re: display.getWidth bug "fixed" in android 3.2
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] supporting 16M colors
Hi, We can see many new Android devices with 16M colors. The most used color depth when drawing on offscreen bitmaps is 16bpp, which results in 64K colors. Is there a way to take benefit of all 16M capable colors of these devices? In iOS i create a 32bpp bitmap and the results are far better than if i created a 16bpp bitmap. I tried to do the same on Android, creating a Bitmap.Config.ARGB_, but the results are the same of creating a RGB_565.

This bug was added in 2009 in the Android bug report system! It was first noticied in Android 1.5 and also occurs in 3.1.

If i'm a programmer that created an application that is in full screen, its obvious that i would not add such flag to the manifest.

[android-developers] showing the default A icon on google maps
Hi,
I would like to know how can i place the default (A) baloon icon that
Google Maps has at the point i asked it to open. I don't need custom
icons, neither a custom text, just an icon or something showing the
center of the screen. My code is this one. I saw some things about
ItemizedOverlay but its proving to be just too complex.
public class MapViewer extends MapActivity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// setup the viewe
MapView mapview = new MapView(this,"...");
mapview.setBuiltInZoomControls(true);
mapview.setClickable(true);
mapview.setStreetView(true);
setContentView(mapview);
if (Loader.isFullScreen)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
// get passed parameters
Bundle extras = getIntent().getExtras();
double lat = extras.getDouble("lat");
double lon = extras.getDouble("lon");
mapview.setSatellite(extras.getBoolean("sat"));
int ilat = (int)(lat * 1e6);
int ilon = (int)(lon * 1e6);
// move the map to the given point
MapController mc = mapview.getController();
if (ilat != 0 || ilon != 0)
mc.setCenter(new GeoPoint(ilat,ilon));
mc.setZoom(21);
}
protected boolean isRouteDisplayed()
{
return false;
}
}
