title: onActivityResult returned from a camera, Intent null
body: <p>I follow the instruction on Camera on <a href="http://developer.android.com/guide/topics/media/camera.html#custom-camera">Android dev site</a></p>
  
  <p>I just start the Camera Intent, not build my own camera. </p>
  
  <p>The sample code to handle result return after taking a photo is as follows. </p>
  
  <pre><code> protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
          if (resultCode == RESULT_OK) {
              // Image captured and saved to fileUri specified in the Intent
              Toast.makeText(this, "Image saved to:\n" +
                      data.getData(), Toast.LENGTH_LONG).show();
          } else if (resultCode == RESULT_CANCELED) {
              // User cancelled the image capture
          } else {
              // Image capture failed, advise user
          }
      }
  
      if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
          if (resultCode == RESULT_OK) {
              // Video captured and saved to fileUri specified in the Intent
              Toast.makeText(this, "Video saved to:\n" +
                      data.getData(), Toast.LENGTH_LONG).show();
          } else if (resultCode == RESULT_CANCELED) {
              // User cancelled the video capture
          } else {
              // Video capture failed, advise user
          }
      }
  }

  <p><code>resultCode</code> is OK, but <code>data</code> is always NULL, which causes a NPE. I looked into the sdcard, the photo was really saved there. Any tip? tks much.</p>
  
  <p>Update: logcat info as requested: </p>
