title: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1888, result=0, data=null} to activity
body: <p>My app allows the user to press a button, it opens the camera, they can take a photo and it will show up in an <code>ImageView</code>. If the user presses back or cancel while the camera is open I get this force close - Failure delivering result ResultInfo{who=null, request=1888, result=0, data=null} to activity... so i am guessing the result=0 is the issue what would I need to insert to make this stop force closing?</p>
  <p>Below is my code. I know I am forgetting something but just cant figure it out! (Admittedly I am about 2 weeks into learning android development). Thanks for any help!</p>
  <pre class="lang-java prettyprint-override"><code>private static final int CAMERA_REQUEST = 1888; 
  private ImageView imageView;
  
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      this.imageView = (ImageView)this.findViewById(R.id.photostrippic1);
  
      ImageView photoButton = (ImageView) this.findViewById(R.id.photostrippic1);
  
  
  
      photoButton.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {
              Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
              startActivityForResult(cameraIntent, CAMERA_REQUEST); 
          }
  
      });
  
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
          if (requestCode == CAMERA_REQUEST) {  
              Bitmap photo = (Bitmap) data.getExtras().get(&quot;data&quot;); 
              imageView.setImageBitmap(photo);
          }  
  </code></pre>
  <p>I guess I would need a &quot;else&quot; in there somewhere but I dont exactly know to do that.</p>
