The android studio git creating applying patches tutorial explains how to use android studio for generating patches which would generally be used for code fixes. And then the tutorial will demonstrate how to apply a patch in the form of a code fix.

This android developers tutorial will be using this tutorial as a real life example.

Code to be used for the patch

The details for the bug fix are to change references to Manifest.permission.CAMERA to android.Manifest.permission.CAMERA.

        try {
            if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if(ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA) ==
                        PackageManager.PERMISSION_GRANTED) {
                    cameraManager.openCamera(mCameraId, mCameraDeviceStateCallback, mBackgroundHandler);
                } else {
                    if(shouldShowRequestPermissionRationale(android.Manifest.permission.CAMERA)) {
                                "Video app required access to camera", Toast.LENGTH_SHORT).show();
                    requestPermissions(new String[] {android.Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION_RESULT);

            } else {
                cameraManager.openCamera(mCameraId, mCameraDeviceStateCallback, mBackgroundHandler);
