Buildozer fails to build apk - Error: Cannot allocate memory

[Roby Zaffa]

I'm trying to build an APK using Kivy and Buildozer, and when I run "buildozer android debug" I receive this error as a response:

#[DEBUG]:        **> Task :**mergeDebugAssets FAILED****
#[DEBUG]:       ERROR:Resource and asset merger: 1 exception was raised by workers:

Here memory status:

I'm running Ubuntu 18.04.5 LTS on Windows 10 WSL 1 and bulldozer.spec is the default.

main.py it's very simple "Hello World" script.


I tried removing WSL and reinstalling everything from scratch but the errors are always the same. Can someone help me? Thank you

Key point : no idea, but I'd suspect the environment.

For unrelated reasons it is probably important to upgrade to wsl2 https://github.com/Android-for-Python/Android-for-Python-Users#usrbingzip-1-elf--not-found

I'd also suggest upgrade to Ubuntu 20 or 22 https://github.com/kivy/buildozer/blob/master/docs/source/installation.rst#android-on-ubuntu-2004-and-2204-64bit

There is one similar too terse error report that is also Win 10 https://github.com/kivy/buildozer/issues/1504 No way to know if this is related.

It is possible the newer versions of Gradle use more memory, so you could try messing with this https://learn.microsoft.com/en-us/windows/wsl/wsl-config but that might just be postponing the inevitable. No way to know.
