title: android how to save captured image into phones gallery
body: <p>I have two activities. In one activity, I have an <code>ImageView</code> and an camera button.
  When I press camera button it goes to other activity where two buttons are there Capture and another is Select button. When I press capture it captures an image. But question is how to save this capture image to gallery. And after pressing the Select button the captured image should display on 1st activity's <code>ImageView</code>.
