title: Camera crashes after taking photo in emulator
body: <p>I'm working on an app that brings the user to the camera via an <code>Intent</code>. I've been working inside the code of the Notepad demo. The problem occurs when I take a photo and confirm it. The app crashes and logcat gives me this:</p>

  <p>My only lead right now is that it has something to do with how I have <code>onActivityResult</code> configured or where I'm putting the code to save image files. Right now I have all of that in one activity:</p>
  
  <pre><code>public void takePhoto (View view) {
      // create Intent to take a picture and return control to the calling application
      Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  
      fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
      intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
  
      // start the image capture Intent
      startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
  
  }
  
  
  private static File getOutputMediaFile(int type){
      // To be safe, you should check that the SDCard is mounted
      // using Environment.getExternalStorageState() before doing this.
  
      File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES), "Notepadv3");
      // This location works best if you want the created images to be shared
      // between applications and persist after your app has been uninstalled.
  
      // Create the storage directory if it does not exist
      if (! mediaStorageDir.exists()){
          if (! mediaStorageDir.mkdirs()){
              Log.d("Notepadv3", "failed to create directory");
              return null;
          }
      }
  
  
      String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date(type));
      File mediaFile;
      if (type == MEDIA_TYPE_IMAGE){
          mediaFile = new File(mediaStorageDir.getPath() + File.separator +
          "IMG_"+ timeStamp + ".jpg");
      } else if(type == MEDIA_TYPE_VIDEO) {
          mediaFile = new File(mediaStorageDir.getPath() + File.separator +
          "VID_"+ timeStamp + ".mp4");
      } else {
          return null;
      }
  
      return mediaFile;
  }
  
  @Override
  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
          }
      }
  }
