Hi, Currently I updated agora rtm to 1.4.10 version. But my customer face crashes like this:
Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x4200010 (has extras) } in io.agora.rtm.internal.ConnectionChangeBroadcastReceiver@48409d at android.app.LoadedApk$ReceiverDispatcher$Args.lambda$getRunnable$0$LoadedApk$ReceiverDispatcher$Args(LoadedApk.java:1629) at android.app.-$$Lambda$LoadedApk$ReceiverDispatcher$Args$_BumDX2UKsnxLVrE6UJsJZkotuA.run(-.java:2) at android.os.Handler.handleCallback(Handler.java:938) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:257) at android.app.ActivityThread.main(ActivityThread.java:8185) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:626) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1015)

More info:
- Agora RTM 1.4.10 using jar file
- Devices: many devices samsung, OPPO, realme, xiaomi,...
- Android OS: 10. 11. 12
May be this happened when network is unknow, because in class ConnectionChangeBroadcastReceiver -> CommonUtility -> Connectivity -> connectivityManager.getLinkProperties(network); will return null if the network is unknown (as this document say https://developer.android.com/reference/android/net/ConnectivityManager#getLinkProperties(android.net.Network) )
Please help me some solution for this Thanks a lot!
@mrkazansky @Kadkad195 i'm talking to SDK team. will update once i get response.
@mrkazansky @Kadkad195 this is a known issue. we will fix the issue in next release 1.4.11, which will be released in early june. before that you may downgrade to 1.4.9 to workaround this issue.
