org/kivy/android/PythonActivity java.lang.NoClassDefFoundError

[jain18aditya]

Hi I am trying to implement Java in Python using Pyjnius

My code:

            PythonActivity = autoclass('org.kivy.android.PythonActivity')
            currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
            context = cast('android.content.Context', currentActivity.getApplicationContext())

While running i am getting below exception

>           PythonActivity = autoclass('org.kivy.android.PythonActivity')

Agree with @takipsizad about the log snipped captured by the original author.

@Blackysh , please open a new issue and provide the log snipped captured via adb logcat on your Android 13 device.
