Buildozer (0.34) fails with this error when set up using Kivy's VM (2.0). I was able to replicate it in an unrelated environment (no VM) in Ubuntu 16.04 and the same spec file.
Log output:
[INFO]: STDOUT: /build/app-name/android/platform/build/build/bootstrap_builds/sdl2_gradle-python2/jni/sdl/Android.mk:8: *** Please define SDL_JAVA_PACKAGE_PATH to the path of your Java package with dots replaced with underscores, for example "com_example_SanAngeles". Stop.
This happened right after it switched to running the NDK build:
Log output:
RAN: /home/kivy/.buildozer/android/platform/android-ndk-r9c/ndk-build V=1
Does anyone have insight into why this error would appear exactly the same way in both the VM and when I set up the environment on my own? Is it Java-related somehow? I will elaborate with more detail, but I'm not sure what would be the most helpful. I can't find references to this error elsewhere, and I would appreciate any clues at all. This is my first question on SO, but this community has really helped me learn. Thank you.
