Bitmap byte-size after decoding?

by

getRowBytes() * getHeight() seems to be working fine to me.

Update to my ~2 year old answer:
Since API level 12 Bitmap has a direct way to query the byte size:
http://developer.android.com/reference/android/graphics/Bitmap.html#getByteCount%28%29

—-Sample code 

    @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR1)
    protected int sizeOf(Bitmap data) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB_MR1) {
            return data.getRowBytes() * data.getHeight();
        } else {
            return data.getByteCount();
        }
    }
