no notification for swapped out app

[fangzhzh]

Description

Hey Twilio!

Mobile devices not receiving incoming call notifications has definitely been an issue for us at Cradle.

We’ve found a specific case that reliably causes an issue on some phones, Specifically Samsung Galaxy phones and also all the Huawei phones we’ve got. The Google Pixel and any simulator phones don’t experience the issue

When we open the the recent apps list then swipe to kill our app, we will not receive notifications at all.

In the logcat, when the app was killed, we get:

I/ActivityManager: Killing 16379:cradle.android.io.cradle.debug/u0a374 (adj 900): stop cradle.android.io.cradle.debug,from pid 3649
W/BroadcastQueue: Background execution not allowed: receiving Intent { act=android.intent.action.PACKAGE_RESTARTED dat=package:cradle.android.io.cradle.debug flg=0x10 (has extras) } to android/com.kddi.android.CpaNotiReceiver

From now on, if this user is called, it will show

GCM: broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE flg=0x10000000

This is all using Twilio Voice 2.0.7 (we look forward to the v3 of the SDK to be production ready!!), we also setup the test using the voice-quickstart-android project and had the exact same experience. Kill the app then you stop getting call notifications.

Is this something you’ve experienced or noticed before? Is it something you’ve tested for? Do you have any suggestions or best practice guidelines as to how best use the SDK and reliably receive incoming call notifications?

I searched the error message and got the issues at firebase-quick-android project, but they didn’t help much.

firebase/quickstart-android#89
firebase/quickstart-android#378

Twilio Android Bug. (We are using GCM)
While making a Call to User, Sometimes On Receiving End, On the below function, Flow is not moving Forward. But the receiver gets the Notification but Not getting Callback on both methodes(onCallInvite & onError).
Voice.handleMessage(context, remoteMessage, new MessageListener() {
@OverRide
public void onCallInvite(CallInvite callInvite) {
Log.v("responce_voice","CallInvite");

}

@Override
public void onError(MessageException messageException) {
    Log.v("responce_voice","CallInvite err");
}

});

@AakashBabu What version of the SDK are you using? Can you please share logs?

[kbagchiGWC]

@AakashBabu Can you file a separate issue for this? This seems like a different than the issue this was opened for.

[AakashBabu]

Twilio SDK : 2.1.0
Android version tested: Lolipop and marshmellow

Did you ever find a solution to this issue? Having the exact same problems with Samsungs for my app.

We have updated our quictstart application. Please refer to the latest and let me know if you have additional question.

For now, I am closing this ticket due to inactivity.
