Sometimes it works, sometimes it doesn't. I am sharing this picture on Facebook, and sometimes it is ok:
And sometimes it is partial black (only the Google map!):
I have a separate thread doing this screenshot:
new Thread() {
@Override
public void run() {
// Get root view
View view = mapView.getRootView();
view.setDrawingCacheEnabled(true);
// Create the bitmap to use to draw the screenshot
final Bitmap bitmap = Bitmap.createBitmap(
getWindowManager().getDefaultDisplay().getWidth(), getWindowManager().getDefaultDisplay().getHeight(), Bitmap.Config.ARGB_4444);
final Canvas canvas = new Canvas(bitmap);
// Get current theme to know which background to use
final Theme theme = activity.getTheme();
final TypedArray ta = theme
.obtainStyledAttributes(new int[] { android.R.attr.windowBackground });
final int res = ta.getResourceId(0, 0);
final Drawable background = activity.getResources().getDrawable(res);
// Draw background
background.draw(canvas);
// Draw views
view.draw(canvas);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
Bundle params = new Bundle();
params.putByteArray("source", b);
params.putString("message", "genie in a bottle");
try {
//String resp =
facebook.request("me/photos", params, "POST");
} catch (FileNotFoundException e) {
throw new RuntimeException(e);
} catch (MalformedURLException e) {
throw new RuntimeException(e);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}.start();
You can create the Bitmap
object directly from the screen using:
bitmap = Bitmap.createBitmap(view.getDrawingCache());
