Don't crash if WallpaperCropActivity isn't passed a URI

        mCropView = (CropView) findViewById(R.id.cropView);

        Intent cropIntent = this.getIntent();

        Intent cropIntent = getIntent();

        final Uri imageUri = cropIntent.getData();

        if (imageUri == null) {

            Log.e(LOGTAG, "No URI passed in intent, exiting WallpaperCropActivity");

            finish();

            return;

        }

        int rotation = getRotationFromExif(this, imageUri);

        mCropView.setTileSource(new BitmapRegionTileSource(this, imageUri, 1024, rotation), null);

        mCropView.setTouchEnabled(true);
