Buildozer: Couldn't find executable for CC

[John Anderson]

Trying to build an APK from a very simple kivy app. I am running on Ubuntu 18.04 using buildozer version 0.39.

In my buildozer.spec file, I have the following lines (in addition to the standard stuff):

requirements = kivy

android.api = 28

android.ndk = 19

log_level = 2

when I run "buildozer android debug", I get:

[ERROR]:   Build failed: Couldn't find executable for CC. This indicates a problem locating the arm-linux-androideabi-gcc executable in the Android NDK, not that you don't have a normal compiler installed. Exiting.

Searching path are: '/home/jra/.buildozer/android/platform/android-ndk-r19/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86/bin/:/home/jra/.buildozer/android/platform/android-ndk-r19/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/:/home/jra/.buildozer/android/platform/android-ndk-r19:/home/jra/.buildozer/android/platform/android-sdk/tools:/home/jra/.buildozer/android/platform/apache-ant-1.9.4/bin:/home/jra/Downloads/brlcad-build/bin:/usr/lib/jvm/default-java/bin:/home/jra/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/jra/bin'

I have attached the complete buildozer.spec and the complete log.

I have seen other complaints about this problem, but no fixes. Can anyone help me?

NDK 19 may not work yet, you should see a warning about that if you're using python-for-android master. Do you get the same issue with NDK 17?

[John Anderson]

That is exactly it. I downloaded ndk version 17c, and using that, the APK builds successfully.
