How to edit Bitmap from gallery correctly?

In my app I get an image from the phone gallery, turn it into a bitmap and change its dimensions to match another bitmap that I'm blending it with. When I download a pic from the internet and access it from the gallery in my app everything works but when I choose a pic from the gallery which was taken on the phone the app craches.

my code:

            String stringUri = null;
            Bundle extras = getIntent().getExtras();
            if (extras != null && extras.containsKey("KEY")) {
                stringUri= extras.getString("KEY");
            }
            Uri uri;
            uri = Uri.parse(extras.getString("KEY"));

            try {
                 bmp = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            bmp=getResizedBitmap(bmp, operation.getWidth(), operation.getHeight());
            bmp.setDensity(c.getDensity());




            myView = new MainView(this, operation, bmp,brush);
            FrameLayout preview = (FrameLayout) findViewById(R.id.preview);
            preview.addView(myView);

}



   public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // CREATE A MATRIX FOR THE MANIPULATION
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);

    // "RECREATE" THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
    return resizedBitmap;
}

And here's my Stack:

Bitmap size will be so big that's why your application crash because of out of memory. In that case, You can compress bitmap before load it in application which may help you from out of memory error.
