Crash on startup

[tlc630]

I'm running android 4.4.4 (kitkat) on a hacked 1st gen Kindle (otterx). All three available versions crash on startup (Gelli has stopped). Would love to try this out. How can I diagnose the issue. I'm new to debugging on android and would be thankful for any and all pointers

If you are comfortable using adb you can use adb logcat to get a log file and post it here. There are also some logcat reader apps on the Play Store. There should be a stack trace from the crash in there.

I was able to reproduce this running kitkat in the emulator. Not sure yet what the issue is though. This seems to be isolated to kitkat (API 19). Can't reproduce this on API 21 and above.

Thanks for the update. I never got that far in my debugging. Hopefully and developer/maintainer will take a look.

Making the App class extend MultiDexApplication makes it start up in a KitKat emulator but on login it crashes because apparently isIgnoreBatteryOptimizations is not found (NoSuchMethodError). Makes sense since this was only added in API 23.
Not sure if we can make it fully compatible with KitKat or anything below Marshmallow, might be too much work/not feasible.

Maybe try a different ROM for your kindle. I think there's a 6.0 available: https://forum.xda-developers.com/t/rom-resurrection-remix-5-7-otterx-6-0-1-marshmallow.3308676/

@dkanada I'm guessing the minSdkVersion should probably bumped to 23?

Thanks for looking into this. I have moved on from Jellyfin/gelli on my android boxes.
