title: How to avoid saving picture at gallery or delete it automatically in Android?
body: <p>The device is Samsung Galaxy III. I developed an APP to run the camera activity and capture an image. After analyzing the image, I print out some text information. Right now every captured image is saved at gallery. I don't need the image to be saved in gallery or SD card. I think either of the following two solutions will work for me, but I don't know how to program it:</p>
  
  <ol>
  <li>avoid saving pictures to gallery. </li>
  <li>delete the picture somewhere in the APP.</li>
  </ol>
  
  <p>Any comments are appreciated. </p>
