Completely clean install of minimal application fails to launch on Android 6

[dessant]

From @Hubro on May 19, 2016 14:49

I have crystax NDK 10.3.1 installed, and a completely clean Python 3.5.1 virtualenv with no packages installed except pip and setuptools.

I run:

pip install cython==0.21
pip install -r req.txt

Here is req.txt:

appdirs==1.4.0
buildozer==0.32
colorama==0.3.7
Cython==0.21
Jinja2==2.8
sh==1.11
six==1.10.0
kivy==1.9.1

And here is main.py:

from kivy.app import App
from kivy.uix.button import Button

class SignalApp(App):
    def build(self):
        return Button(text="Signal app!")

SignalApp().run()

It runs fine using python main.py.

Then:

buildozer android_new debug
buildozer android_new deploy
buildozer android_new run

Here is my buildozer.spec:

[app]

# (str) Path to build artifact storage, absolute or relative to spec file
# build_dir = ./.buildozer

# (str) Path to build output (i.e. .apk, .ipa) storage
# bin_dir = ./bin

It takes a while, but the build succeeds and deploys the app.

When the app runs on Android, it says "Loading..." for a second and then closes. If I try to bring the app to the foreground it says "Unfortunately, Kvantel Signal App has stopped."

Logcat output when running the app:
