SDK authorization login successful without returning to the application

[zhaohang-soul]

What did you do?

Using linesdk for third-party authorization login

What did you expect?

After successful authorization login, return to the application and execute the login logic in the onActivityResult method

What happened actually?

After successfully logging in with SDK authorization, I still stay on the Line main interface and have not returned to my application

Your environment?

Android15，linesdk:5.8.0&linesdk:5.10.1

@zhaohang-soul ,
Thanks for reporting this issue.

I couldn't reproduce this issue using below setting:

1. Android 15 emulator: Pixel 8 Pro
2. LINE SDK v5.10.1 and LINE App v14.11
3. LINE SDK sample app (current repo)

Could you provide more details on:

1. Will it happen in LINE SDK sample app on your side?
2. What's the LINE App version you used? Will LINE App's latest version (ex: v14.10 or v14.11) solve this issue?
3. Does it work on Android 14 and below? If not, please provide Android version and the device you use. Thanks.
4. What's the Android 15 device you used?
5. The other reporter mentioned cocos creator, did you also use cocos creator? Reference issue: line app在已经登录的情况下，我的应用程序调sdk登录，登录完成，无法返回我的应用程序 #141
6. When that happened, did login succeed when you opened your application manually?

I still stay on the Line main interface and have not returned to my application

Many thanks.

@zhaohang-soul ,
Thanks for providing detail info.
I also was wondering:

1. Because Android 15 is not officially released yet, what beta version of Android 15 did you use? Was it Beta 3.1? https://developer.android.com/about/versions/15/release-notes
2. Will this issue happen on emulator of Android 15? Emulator image version: Google Play ARM 64 v8a System Image, Revision 6? I don't have a physical device with Android 15, so I'm using an emulator to reproduce it.

Thanks.

@YkSix
Is there log output and switch control in the SDK

[zhaohang-soul]

The code has been returned at this point, is there any good adaptation method
