Fatal signal 6 (SIGABRT) when switching applications
Context:
- My application uses webview to display a report with some data.
- This webview has a toolbar on top with a print button.
- When you press the print button opens a menu that allows the user to choose from a list of applications that can print the report.
- Printing process: take a screenshot of the report, compress it to reduce its size, send the png to the printer application.
Problem:
- When the printer app opens with a printable image, I get an ANR saying my background app has stopped working.
- If I press the back button on android the app is still alive and I can navigate without any error, which is strange, I just got a warning that it stops working.
Some code for enlightenment:
Code that takes a screenshot and sends to the print application
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.print) {
Bitmap bitmap = Util.screenShot(mWebView);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
File file = new File(Environment.getExternalStorageDirectory() + File.separator + "screenshot.png");
try {
file.createNewFile();
FileOutputStream fo = new FileOutputStream(file);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
e.printStackTrace();
}
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/png");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}

Oh, I see your mistake. You are using this:
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
which creates a JPEG image in CompressFormat and in the intent you are sending the PNG image
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/png");
what is causing the error. To resolve this, use PNG instead of JPEG.
