object is a sort of wrapper around an image that lets you draw on the image. They are usually temporary, and don't actually own the pixels that you're drawing.
In your case, <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<bitmap android:src="@drawable/ic_circle"
android:gravity="center" />
</item>
</layer-list>
is just providing the ability to draw onto mRecordButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
countDownTimer.cancel();
mIsRecording = false;
mIsTimelapse = false;
// Starting the preview prior to stopping recording which should hopefully
// resolve issues being seen in Samsung devices.
try {
startPreview();
mMediaRecorder.stop();
mMediaRecorder.reset();
} catch (Exception e) {
e.printStackTrace();
}
Intent mediaStoreUpdateIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaStoreUpdateIntent.setData(Uri.fromFile(new File(mVideoFileName)));
sendBroadcast(mediaStoreUpdateIntent);
goNext();
}
});
, which is where the image actually lives in memory.
You should throw away the Graphics and return the gfxScreenshot:
bmpScreenshotThen you can assign the bitmap to a Graphics:
Bitmap
