MIT App Inventor 2 aiStarter error?

When running aiStarter, I receive the following error:

Bottle server starting up (using WSGIRefServer())...
Listening on http://127.0.0.1:8004/
Hit Ctrl-C to quit.

Shutdown...

I am trying to USB debug but aiStarter cannot find my device. The app inventor knows when aiStarter is running, but cannot see my tablet.

Yes I have USB debugging enabled, and I have never had this problem until now. I am using OSX.

This error is usually caused by two processes using the same port trying to connect to your Android device.

Cause

You are likely having multiple instances of aiStarter trying to use the default port to access your device. Make sure to remove all background ones. background.

Solutions

  • Locate the other aiStarter process(es), and stop them.
  • Reinstall aiStarter
