Maybe this helps.


Hello! And welcome to the AppyBuilder Community and the AppInventor World! Here you can learn a lot, enjoy a very satisfying journey and productive way to develop applications.

About your question, I recommend @mirxtrem_apps’ extensions as you can find in these posts:

Also, mirxtrem has videotutorials in youtube (in spanish, but I think you can activate subtitles) to do this.

Other method you can achieve that is @Ben’s Extended WebViewer with oauth (use EnableOAuth block).


Thank you for help sir.
I’ll try it. But if i have trouble , I’ll ask that again sir.

How to avoid runtime errors with the companion app

  1. After importing an extension, please restart the companion app.
  2. If you like to use an extension on a different screen, in Screen1 additionally drag the extension into the working area.

While starting the companion app, all necessary assets and also the imported extensions of your project will be copied to your device. So in case the no such class error shows up, the extension code to run the extension is not available on your device. Without that code the companion app is not able to execute methods from the extension.



Thanks for help sir.
