Android scaling copy of image instead of changing source image

I have the following code for getting small sized avatar image:

    Bitmap b= BitmapFactory.decodeFile(selectedImagePath);
    File file = new File(selectedImagePath);
    Bitmap out = Bitmap.createScaledBitmap(b, 128, 128, false);
    FileOutputStream fOut;
    try {
        fOut = new FileOutputStream(file);
        out.compress(Bitmap.CompressFormat.PNG, 100, fOut);
        fOut.flush();
        fOut.close();
        b.recycle();
        out.recycle();
    }

The problem is that after executing this code, my image in gallery is rescaled too, but I must leave it without any changes. I tried to use copy of Bitmap image like this:

Bitmap bmp2 = b.copy(b.getConfig(), true);
Bitmap out = Bitmap.createScaledBitmap(bpm2, 128, 128, false);

or

Bitmap bmp2 = Bitmap.createBitmap(b);
Bitmap out = Bitmap.createScaledBitmap(bpm2, 128, 128, false

But my original image still changes. How could I obtain new, independent copy of this image?

You are loading the image from "selectedImagePath" and then your output file points to the same path, when you call compress() you overwrite your original image.

Try making a new name for the resized image.

fOut = new FileOutputStream(renamedFile);
