If the user rotates the screen, the image & result will be lost. I suggest retaining the state of at least the TextView result.
If the user rotates the screen while the request is being processed, it will result in a NullPointerException crash. This is similar to #5 except this may actually still have valid data as it is delayed until the processing finishes.
