While creating a bitmap, you should probably scale down the image
size. This is how you should do it.
BitmapFactory.Options bmpFactory = new BitmapFactory.Options();
bmpFactory.inSampleSize = 4;
Bitmap bmp = BitmapFactory.decodeFile(path, bmpFactory);
The sample size 4, will scale down the bitmap to 1/4 of the original
size. This will, in turn, reduce the size of the Bitmap object by a
factor of 4. Hope this helps.
Thanks and Regards,
