Android App Keeps Stopping

[comradesparklepony]

Hello,

I have an LOVE android app which I am moving to love 11.4. Everything compiles fine, but when I try to run it, it appears to stop instantly, and I get the notification "<app name> keeps stopping". I've tried clearing the app cache, and cleaning and rebuilding the project, but the issue persists. I tried attaching a debugger, but the app stops before the debugger can do anything. Any ideas?

Thank you!

Couple updates:

If I rebuild the project, I get the following error:

Code: Select all

But the submodule does appear to be present. When I run

Code: Select all

git pull --recurse-submodules

it says that I am up to date, and I did make sure to clone the submodules correctly when first downloading. I'm not sure why I was not getting this error before.

Thank you!

It seems like you do not have Python installed (so Python script is not able to run and thus is not able to detect love)...

Install Python (or if you have python3 installed, alias it to python)

[comradesparklepony]

I did have python3 installed, but not aliased to python. For some reason aliasing didn't work, probably because I'm using Android Studio, but manually changing the makefile to use python3 instead did. So thank you for catching that!

That said, I still am getting the issue with the app stopping. I did find a different tab in Android Studio with some debug information:

I found same error reported in the issue tracker and there seems to be some patch and solution
See https://github.com/love2d/love-android/issues/208

Thanks for the link, good find! Yep, looks like running it with an x86_64 emulator instead of an x86 emulator fixed it. Thank you!
