@iaulakh can you please check that issue - please note that it happen if I press hangup very fast, right after call started

[iaulakh]

Hi @vovanb, We already fixed this issue in native SDK. I will let you know once SDK version is released, either this or next week. Then you can update SDK version. Thank you.

[iaulakh]

Please update to https://mvnrepository.com/artifact/com.azure.android/azure-communication-calling/2.11.0-beta.1.

[vovanb]

sorry @iaulakh how I can update SDK in existing project?

[iaulakh]

Please use implementation 'com.azure.android:azure-communication-calling:2.11.0-beta.1'.

[vovanb]

@iaulakh well, I modified attached downloadJarScript .txt to use azure-communication-calling-2.11.0-beta.1.aar then in CommunicationCallingSampleMauiApp.csproj and in AndroidMauiBindings\Android.CallingUI.Bindings\Android.CallingUI.Bindings.csproj changed to use azure-communication-calling-2.11.0-beta.1.aar

and then I got below errors on compile:

should I update all packages ?

[iaulakh]

Hi @vovanb , Thank you for trying the latest beta SDK. We will attempt to reproduce the issue on our side and will share our findings and resolution.

[iaulakh]

Hi @vovanb Please try Commit.

[vovanb]

Hi @iaulakh If I keep in Android.CallingUI.Bindings.csproj Jars\azure-communication-ui-calling-1.10.0-beta.1.aar it compiled correct but crashed in run-time But I can not found that it using new azure-communication-calling-2.11.0-beta.1.aar - where It should be referenced? can you please provide your CommunicationCallingSampleMauiApp.csproj?

[iaulakh]

Hi @vovanb , Please look at commit.

[vovanb]

compiled ok - no crash so far

[vovanb]

@iaulakh reopened case again - I found another problem (maybe not related to last commit, since it was in previous too) that speaker is not selected all the time - sometime it is, but sometime I need to change speaker-android->speaker and then it is working Could you please help?

[iaulakh]

Hi @vovanb, Please open new issue as this is not related to crash.
