Android Screen Recorder

I am trying to capture screenshots for Android when I draw something on the screen and after creating the video. It seems to me that I am doing this with a for loop, but I had problems when I called the getDrawingCache () method. In principle, it works correctly, but if I change something on the screen when I call the "drawing cache", the android application closes without an error message. Below is my source code.

public void run() {
        Bitmap screenshot;
        File file;
        FileOutputStream fileOutputStream;

        this.view.setDrawingCacheEnabled(true);

        for (long i = 1; record; i++) {

            screenshot = (Bitmap) Bitmap.createBitmap(view.getDrawingCache());

            file = new File(directory, "frm" + i + ".jpg");

            try {
                fileOutputStream = new FileOutputStream(file);

                screenshot.compress(CompressFormat.JPEG, 10, fileOutputStream);

                fileOutputStream.close();
                ScreenshotRecorder.sleep(50);

            } catch (InterruptedException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
        this.view.setDrawingCacheEnabled(false);

    }

I was looking for another way to get an Android registrar, but I did not find an open source application. If anyone knows how to get Android screen capture, I am grateful. Thanks to everyone.

Try:

view.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
view.buildDrawingCache(true);
