I am using python 2.7 ubuntu 17 and I already tried Buildozer 0.32 fails to build

I don`t know what is missing. Thanks in advance

Find solution myself

Error:

The error is in building sdl2 for armeabi-v7a ,because your current version of sdk ndk or ndk in .buildozer has incomplete downloaded or some other error

Building sdl2 for armeabi-v7a
[INFO]:    -> directory context /home/kallz/Project/AndroidLib/examples/FaceD/.buildozer/android/platform/build/build/bootstrap_builds/sdl2-python2/jni
[INFO]:    -> running ndk-build V=1
Exception in thread background thread for pid 5175:
Traceback (most recent call last):

Solution:

1. delete .buildozer directory in the home directory for Linux( where android SDK ndk or ant installed)
2. delete .buildozer directory from your project or app
3. delete buildozer.spec file

Now start again, run following command in project directory

1. buildozer init
2. buildozer -v android debug # to make the only apk

Last command auto download sdk ndk or ant again in .buildozer in home directory
