"Activity doesn't exist" #90

Closed Rob-Mat94 closed 3 years ago

Rob-Mat94 commented 3 years ago

Hi, I'm trying to receive call in background, so i follow the example, i add all the permission, etc ... I'm testing with FCM online tester. When i received the push notification, i'm trying to call "displayIncomingCall" but i got the following error : "Activity doesn't exist". Here is the log :

I/flutter (26016): Handling a background message: 0:1626366993137601%dc8262c0dc8262c0 I/flutter (26016): backgroundMessage: displayIncomingCall D/RNCK:VoiceConnectionService(26016): setAvailable: false D/RNCK:VoiceConnectionService(26016): setAvailable: true D/FLT:CallKeepModule(26016): backToForeground, app isOpened ?false

What can i have to add in android folder or dart code in order to work ... ?

Hi @Rob-Mat94,

I've opened a pull request with an updated example and instrustions. Could you test that and see if you get the same result. See #91

RobotMaths commented 3 years ago

Hi, thanks for your reply ! I will test that tomorrow. This error happens when the app is in background (Android) or terminate state. I didn't know if it was normal. Did you also fix the iOS crash in background ? I see many people which have this problem.

All the firebase message callers have been refactored to support the newer libraries. When I tested iOS you can push the notification fine. The call will just fail to pick up as ios requires an audio stream for a call to continue.

Also iOS apps will have to be installed for background tests and iOS doesn't allow debug apps to run without an xcode connection.

Hi @AntonyLeons, i tested your update and all worked well. backToForeground(); is working now. I will soon try to pair callkeep with a webrtc call from 'flutter dart_sip_ua' to be sure. I just have one remark, when i used await callKeep.answerIncomingCall(event.callUUID); in the callback function. It seems that the is a infinite loop.

HI @Rob-Mat94

I believe i fixed this in a commit 2 days ago, i cant replicate it

Rob-Mat94 commented 3 years ago

I used your repository https://github.com/AntonyLeons/callkeep.git with your commit but, maybe i have to use _callKeep.startCall(event.callUUID!, callerId, callerName); i think like the example.

I'm trying to do the same thing.

if you have this commit fix recursive call bfdde71

it should have worked, let me know how you get on

RobotMaths commented 3 years ago

Hi, so like you suggest I follow your commit bfdde71. With Function(CallKeepPerformAnswerCallAction) answerAction = (event) async { // SIPController.controller.signalAnswer(); await callKeep.setCurrentCallActive('608'); }; And it's working, thanks !.

Note (if its useful) : The function answerIncomingCall() still be recursive and startCall() throw me a exception : java.lang.NullPointerException: Attempt to invoke virtual method 'int android.content.Context.checkPermission(java.lang.String, int, int)' on a null object reference My callkeep functions are in top main.

Another things, there is a way to have the timer in callscreen ?

RobotMaths commented 3 years ago

Hi @AntonyLeons, so i finished with Android (great work !). Now I'm trying to do to the same things on iOS but I need your help :/. All my project is configured well (VoIP Certificates, background process enable, etc ...). On background state, I would like to display incoming call but an error that I don't understand fired on callkeep deployment.

I'm testing on an iPhone 6S (debug mod), with iOS 12. I keep the same background callback as Android :

`static Future firebaseMessagingBackgroundHandler( RemoteMessage message) async { await Firebase.initializeApp(); //SIPController.controller.register(listener); print("HANDLING BACKGROUND message !"); if (!callKeepStarted) { try { await callKeep.setup(CallKeepCallbacks.callSetup); callKeepStarted = true; } catch (e) { print(e); } } callKeep.on( CallKeepPerformAnswerCallAction(), CallKeepCallbacks.answerAction); callKeep.on(CallKeepPerformEndCallAction(), CallKeepCallbacks.endAction);

await callKeep.displayIncomingCall('608', 'Portier 608', hasVideo: false);
callKeep.backToForeground();

}`

I get the same error with the callKeep.setup using callkeep: ^0.3.1:

Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
  final callKeep = FlutterCallkeep();
  callKeep.setup(null, <String, dynamic>{
    'ios': {
      'appName': 'CallKeepDemo',
    },
    'android': {
      'alertTitle': 'Permissions required',
      'alertDescription':
      'This application needs to access your phone accounts',
      'cancelButton': 'Cancel',
      'okButton': 'ok',
      'additionalPermissions': <String>[],
      'foregroundService': {
        'channelId': 'com.company.my',
        'channelName': 'Foreground service for my app',
        'notificationTitle': 'My app is running on background',
        'notificationIcon': 'Path to the resource icon of the notification',
      },
    },
  });
}

@Rob-Mat94 did you pass permissions to the setup config or did you add them in the AndroidManifest.xml. Also could you share what permissions you added?
