Cannot grant permission(interact_across_users_full) to run app

[crowo]

App doesn't start as it tries to launch nonexistent intent to obtain permissions as I explained in another issue.
I try to give all permissions manually but executing sudo pm grant dev.legendsayantan.extendroid android.permission.INTERACT_ACROSS_USERS_FULL but no luck. even converting it system app didn't help. as I understand it's only possible if the app is signed by platform key. any ideas to use this app? BTW I don't care about user management functionaly

You don't need to grant any permission manually, other than the Xiaomi floating window permission if running on MIUI. The app uses shizuku access to manage its own permissions.

[crowo]

then why it tries to open miui's permission intent thus doesn't start? said permission is only permission the app lacks currently and shizuku part is also ok.

[legendsayantan]

That permission is only required for MIUI, won't be needed otherwise. Currently it's crashing on your custom rom because of a development bug which will be fixed soon.

I'm looking forward to it because it's the only app which promise to solve my problems about freeform and simultaneous playback.
