CallKeepPerformAnswerCallAction handler not involked on Android

[KienDangTran]

I've successfully received incoming call using FCM push on android device & default call screen of the OS has been shown, but when I click answer call button, CallKeepPerformAnswerCallAction handle is not invoked, it stays in call screen. The reject button works well. CallKeepPerformEndCallAction handler is invoked

On iOS both button work well when received a foreground push.

This is my code

      await _callKeep.setup(mainAppNavKey.currentContext, callSetup);
      final hasPhoneAccount = await _callKeep.hasPhoneAccount();
      if (!hasPhoneAccount) {
        await _callKeep.hasDefaultPhoneAccount(
          mainAppNavKey.currentContext!,
          callSetup,
        );
      }

      _callKeep.on(CallKeepPerformAnswerCallAction(),
            (CallKeepPerformAnswerCallAction event) async {
          final callUUID = event.callUUID!;
          print('[answerCall] $callUUID, number: +8418612345678');
        });

      FirebaseMessaging.onMessage.listen((msg) async {
        log('onMessage: ${msg.data}', name: '$runtimeType');
        // Handle data message
        final callerId = msg.data['caller_id'];
        final callerName = msg.data['caller_name'];
        final uuid = msg.data['uuid'];
        final hasVideo = msg.data['has_video']?.toString() == 'true';
        await _callKeep.displayIncomingCall(
          uuid,
          callerId,
          handleType: 'number',
          localizedCallerName: callerName,
          hasVideo: false,
        );
      });

I'm using version 0.3.1
