java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1888, result=0, data=null} to activity

Question

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 imageview. 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?

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!

    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("data"); 
        imageView.setImageBitmap(photo);
    }  

I guess I would need a "else" in there somewhere but I dont exactly know to do that.

below is the logcat

Adding this first conditional should work:

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if(resultCode != RESULT_CANCELED){
        if (requestCode == CAMERA_REQUEST) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
        }
    }
}
