Using pyjnius leads to crash (sometimes?) if app built by new toolchain

[germn]

There's no crash message in logs, but we'll see this lines while app initialization:

[ERROR ] Input: AndroidJoystick is not supported by your version of linux

Traceback (most recent call last):

File "/home/kivy/test/.buildozer/android/platform/build/dists/test/private/lib/python2.7/site-packages/kivy/input/providers/__init__.py", line 57, in <module>

File "/home/kivy/test/.buildozer/android/platform/build/dists/test/private/lib/python2.7/site-packages/kivy/input/providers/androidjoystick.py", line 20, in <module>

Exception: android lib not found.

and

[WARNING] Base: Unknown <android> provider

Here's full typical log.

Problem was originally discovered here, but affects also Python 2.7 builds with Android NDK.

There's no such problem with old toolchain.

I got it working!

Based on discussion here I created ugly patch that replaces org.renpy.android.PythonActivity with org.kivy.android.PythonActivity inside pyjnius:

def autoclass(clsname):
+    if clsname == 'org.renpy.android.PythonActivity':
+        clsname = 'org.kivy.android.PythonActivity'

And after that pyjnius works without crashes. You can test it here:

I don't know how pyjnius/Java work, so it's hard for me to create normal fix.
May be information above will help someone who'll try to do it.

These are three separate issues, two of them affects log, one of them about pyjinus:
