Overview

• When this library is applied to Fragment and run on Android 8.0, "System UI has stopped" is displayed.

Expected

• Works on Android 8.0

Actual

• Doesn’t work on Android 8.0.

Environment

• Which library version are you using?

  • 4.5.0

• On which devices do you observe the issue?

  • Android8.0

• Note any other information that might be useful

  • The following versions will work:
    • 6.0.1
    • 7.0
    • 7.1.1
    • 8.1
    • 9.0
    • 10
  • I think you should use ActivityCompat#requestPermissions method on Fragment
    • https://github.com/permissions-dispatcher/PermissionsDispatcher/blob/master/processor/src/main/kotlin/permissions/dispatcher/processor/impl/kotlin/KotlinFragmentProcessorUnit.kt#L22
    • On Activity, you use it
      https://github.com/permissions-dispatcher/PermissionsDispatcher/blob/master/processor/src/main/kotlin/permissions/dispatcher/processor/impl/kotlin/KotlinActivityProcessorUnit.kt#L23

Reproducible steps

1. Ready on Android8.0 device ( What I saw was an emulator.)
2. Run the following branch.
   https://github.com/kwmt/PermissionsDispatcher/tree/system-stop-on-fragment

This is a difference.

Thx! In summary in Android 8.0 Fragment#requestPermissions has a bug and causes a crash? 👀 Let us check anyway 🙇

I've tried kwmt#1 with 8.0.0 emulator but somehow couldn't see the error. Could we get more detail or error message if possible? 🙇 @kwmt

Hi, @hotchemi
Thank you for trying. It's a mystery 🤔

• As you can see, no error log.
  

I hope this will help.

In PermissionsRequestFragment onAttach Method
activity?.requestedOrientation = if (context.resources.configuration.orientation == ORIENTATION_PORTRAIT) ActivityInfo.SCREEN_ORIENTATION_PORTRAIT else ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE

Android8.0 can't set orientation sometime ,Please fix this bug

Caused by: java.lang.IllegalStateException: Only fullscreen activities can request orientation
