Code Samples

Accessing the onActivityResult method

When we call the startActivityForResult method, once our request has been called the onActivityResult will be called supplying details of our requestId, whether our request was successful and if so the data containing our image.

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent resultData) {
        if(requestCode == REQUEST_FOLDER_CODE && resultCode == RESULT_OK) {
            Uri uri = null;
            if(resultData != null) {
                uri = resultData.getData();
             }
        }
    }
