Take picture with drawable/paint on face using vision api

What I am trying?

I am trying to take picture with drawable/paint on face but, i am not able to get both on same picture.

What I have tried?

I have tried using CameraSource.takePicture but i am just getting face without any drawable/paint on it.

mCameraSource.takePicture(shutterCallback, new CameraSource.PictureCallback() {
            @Override
            public void onPictureTaken(byte[] bytes) {
                try {
                    String mainpath = getExternalStorageDirectory() + separator + "TestXyz" + separator + "images" + separator;
                    File basePath = new File(mainpath);
                    if (!basePath.exists())
                        Log.d("CAPTURE_BASE_PATH", basePath.mkdirs() ? "Success": "Failed");
                    String path = mainpath + "photo_" + getPhotoTime() + ".jpg";
                    File captureFile = new File(path);
                    captureFile.createNewFile();
                    if (!captureFile.exists())
                        Log.d("CAPTURE_FILE_PATH", captureFile.createNewFile() ? "Success": "Failed");
                    FileOutputStream stream = new FileOutputStream(captureFile);
                    stream.write(bytes);
                    stream.flush();
                    stream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });

I also tried using :

mPreview.setDrawingCacheEnabled(true);
        Bitmap drawingCache = mPreview.getDrawingCache();
        try {
            String mainpath = getExternalStorageDirectory() + separator + "TestXyz" + separator + "images" + separator;
            File basePath = new File(mainpath);
            if (!basePath.exists())
                Log.d("CAPTURE_BASE_PATH", basePath.mkdirs() ? "Success": "Failed");
            String path = mainpath + "photo_" + getPhotoTime() + ".jpg";
            File captureFile = new File(path);
            captureFile.createNewFile();
            if (!captureFile.exists())
                Log.d("CAPTURE_FILE_PATH", captureFile.createNewFile() ? "Success": "Failed");
            FileOutputStream stream = new FileOutputStream(captureFile);
            drawingCache.compress(Bitmap.CompressFormat.PNG, 100, stream);
            stream.flush();
            stream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

in this case i am only getting what i draw on face. Here, mPreview is the CameraSourcePreview.

Just added capture button and added above code in this google example.
