Description

Hi, could you please modify PythonActivity.java to either add additional options or to gracefully handle cases where the android.manifest.orientation parameter is already specified in the manifest? This adjustment would prevent conflicts and ensure smoother integration with buildozer.spec configurations.

Currently, users need to set it inside the app using mActivity.setRequestedOrientation. For example: mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_USER), full minimal code:

from android import mActivity

from jnius import autoclass

ActivityInfo = autoclass('android.content.pm.ActivityInfo')

mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_USER)

Screenshot from app's ipykernel (part of my sample in git repository):

Then everything works ok..

Spec file:

orientation = portrait
android.manifest.orientation = fullUser
