DBAccessError permission denied in app

[Firnagzen]

Having successfully built and pushed the app to my phone, a Samsung Galaxy Nexus (maguro, GSM version), the app displays a kivy loading screen before crashing. The logcat, from buildozer android logcat, is as follows:

Traceback (most recent call last):
  File "/usr/local/bin/buildozer", line 5, in <module>

There are currently no read/write operations in my app; I commented them out for testing purposes. Furthermore, I have given the permissions READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE in the buildozer.spec, just in case.

Hi, This issue wasn't about a read/write in your app, but Buildozer's database that fail to be opened for an unknow reason. We changed the storage to json now, and it has another read/save mechanism, so it might help.

Ensure you have no runned the buildozer with sudo one time, and without sudo next time. You must NEVER use sudo with buildozer.
