What is specifically happening in your onCreate method at line 62? That's where the null exception is coming from.
Also, you might want to use the BitmapFactory.Options to help in image creation. You can easily tweak the options to get image dimensions without having to create the actual bitmap (see inJustDecodeBounds) and you can adjust the sample size to put less memory strain on your application. Try this: BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 2; options.inTempStorage = new byte[16*1024]; options.inJustDecodeBounds = false; Bitmap b = BitmapFactory.decodeStream(inputStream,null,options); Then test "b" to make sure it isn't null before loading it into your ImageView.
