p4a crash "Couldn't find the built APK"

• Python: 3.6
• OS: Ubuntu 18.04
• Kivy: N/A
• Cython: 29.0.1

Description

p4a crashes after gradle build, using master installed here 12/13/2018

Problem is p4a expects gradle output in:

~/.local/share/python-for-android/dists/ex/build/outputs/apk/debug

but gradle creates the .apk in:

~/.local/share/python-for-android/dists/ex/build/outputs/apk

I have no idea why this changed.

The workaround is on line 852 of toolchain.py

                # gradle output apks somewhere else
                # and don't have version in file
                apk_dir = join(dist.dist_dir,
                               "build", "outputs", "apk")
                               #args.build_mode)     ##WORKAROUND remove argument##

buildozer.spec

Command:

p4a apk

Did you build completely fresh, removing your old distribution?

New distributions will have a newer gradle, where the output path is indeed different. But if you're building an existing older distribution with the old gradle still lying around, that might be the problem.

--clean_all and reinstall p4a fixed the problem.
Gradle version makes sense to me.
Thanks
