title: Why doesn't my Toast show up?
body: <p>My toast doesn't show up until after the file has completed downloading (I commented the download function). Any ideas why?</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      ImageView main_image_view = (ImageView)this.findViewById(R.id.main_image_view);
      TextView text_view = (TextView)this.findViewById(R.id.main_text_view);
  
      Context context = getApplicationContext();
      CharSequence text = "File Not Found. Downloading... Please be patient, it's a large file!";
      int duration = Toast.LENGTH_SHORT;
  
      Toast toast = Toast.makeText(context, text, duration);
      toast.show();
  
      // This function fetches a file from a URL.
      brain = get_frame_fl(file_name, mActive_slice);
      brain_slice = Bitmap.createBitmap(brain_pixels, frame_width, frame_height, Bitmap.Config.ARGB_8888);
  
      // display
      main_image_view.setImageBitmap(brain_slice);
  }
  </code></pre>
