Answer 1

You have to put mCamera.startPreview(); inside your onPictureTaken() function to restart preview again, because it stops automatically when the picture is taken.

Answer 2

Maybe this will help. From Android SDK documentation on takePicture():

After calling this method, you must not call startPreview() or take another picture until the JPEG callback has returned.

The JPEG callback is implementation of onPictureTaken(), as I understand. So you should defer your call to startPreview.

Answer 3

mCamera.takePicture(null, null, mPicture);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
//Do something after 1000ms
       mCamera.startPreview();
           }
     }, 1000);
