Kolibri app crashed on Android 5.0.1

[mrpau-richard]

Kolibri app crashed after I install and launch it on physical Android version 5.0.1 device. I'm using the installer built in this PR with this installer file name Kolibri_dist__armeabi-v7a-release-0.13.4a0.dev0+git.101.g01d7cf71-3d07473-dev-.apk.

@mrpau-richard Are you able to run adb commands in your testing environment? (i.e. is your Android device set up for debugging?) If so, could you plug your Android device into a computer via usb and run adb logcat, then start the build and send us any output from adb logcat?

@kollivier here's the adb logs on my Android device:

Did you run adb logcat and then start the Kolibri app? These logs don't indicate any attempt to start or run Kolibri in them.

[mrpau-richard]

Yeah that's what I did. I uploaded the compiled logs in the txt file for you to debug it. android-5.0.1-log.txt

I found this Kolibri related errors in the adb logs.

Ah, great, thanks! That log file has the error in it. Posting it here, for future reference:

Unfortunately, not sure what the cause for this might be. "is not visible" sounds different from "cannot be found". The only thing I can find related to this is:

https://stackoverflow.com/questions/211176/interface-is-not-visible-from-classloader-when-using-a-proxy

Will have to dig into this more!

any updates on this?

[jamalex]

We should try to replicate this on a 5.0.1 device at some point and close if we can't get the error to show up.

[rtibbles]

Our minimum API level is now 23, Android 5.1 is API level 22. Closing this as won't fix.
