title: PictureCallback.onPictureTaken never called
body: <p>I am writing an application that needs pictures taken with the camera. The problem occurs when I try to take an actual picture. Here's the code that is troubling me:</p>
  
  <pre><code>    final ShutterCallback shutterCallback = new ShutterCallback() {
          @Override
          public void onShutter() {
              Log.d(TAG, "onShutter");
          }
      };
  
      final PictureCallback callback = new PictureCallback() {
  
          @Override
          public void onPictureTaken(byte[] data, Camera camera) {
              Log.d(TAG, "onPictureTaken - jpeg");
              try {
                  //async task for storing the photo
                  new SavePhotoTask(CameraView.this.ctx, data).execute();
              } catch (final SavePhotoException e) {
                  //some exceptionhandling
              }
          }
      };
      this.camera = Camera.open();
      this.camera.setPreviewDisplay(surfaceHolder);
      final Camera.Parameters parameters = findBestParameters(w, h);
      this.camera.setParameters(parameters);
      this.camera.startPreview();
      Log.d(TAG, "takePicture now!");
      this.camera.takePicture(shutterCallback, null, callback);
  </code></pre>
  
  <p>On the emulator it seems to work out but on my phone (Motorola Defy - android 2.1). </p>
  
  <p>The actual problem: on the phone the picturecallback is never happening "onPictureTaken" gets never called. The Shuttercallback is executed but the other is not (and I tried with raw instead of jpeg, same thing).</p>
  
  <p>Does anyone know this problem? I just don't see where the difference lies to the emulator right now. I appreciate your help.</p>
