Android ImportError

Navigator

Hello,

I am attempting to test an experiment on Android but it keeps crashing as soon as the experiment starts (after entering the subject ID and location for data). I'm running on Android version 8.1.0 and the experiment is built with OpenSesame version 3.1.8 with the backend set to droid and the resolution set to 1280 x 800. Given that the debug file says something about an ImportError to do with plugins I've tried disabling all the plugins, but it still doesn't work. Strangely the example experiment that comes with the Android runtime doesn't work either. Nor does a barebones experiment with only a sketchpad. Here's the debug file generated:

Any help would be greatly appreciated!

Hi Navigator,

The Android runtime isn't maintained anymore, and doesn't work at all on many devices. So (even though it may still work on some devices), I would recommend against using it. Perhaps running an online experiment with OSWeb in the Android browser is an alternative?
