Kivy buildozer can't copy libs for armeabi-v7a
<p>I have been trying to fix this issue for days and I can't seem to find any answer. I'm using the Crystax NDK with python3. I've tried using it with python2.7 and the Google NDK as well but it doesn't make a difference. It seems like buildozer just can't find the .so files it needs to copy for armeabi-v7a. Here is the log:</p>
