NullPointerException while retrieving image form camera activity

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

While Trying to save my image from Camera activity from here i am getting the following error at the last line of the function i.e. imageView.setImageBitmap(photo);

11-03 03:27:21.928: E/AndroidRuntime(27303): Caused by: java.lang.NullPointerException

Chances are that the image is correctly been retrieved from camera, but your imageView object is null. You should do somewhere before accessing it something like this.-

imageView = (ImageView) findViewById(R.id.yourImageId);

Also, make sure you're not shadowing the instance variable imageView redefining it in another method (such as onCreate) like this.-

ImageView imageView = (ImageView) findViewById(R.id.yourImageId);
