Hi! Try to add

    <uses-permission android:name="android.permission.BIND_TELECOM_CONNECTION_SERVICE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />

and

        <service android:name="io.wazo.callkeep.VoiceConnectionService"
            android:label="Wazo"
            android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE">
            <intent-filter>
                <action android:name="android.telecom.ConnectionService" />
            </intent-filter>
        </service>

to AndroidManifest

[muhammedrashidm]

Thank you reko . But I've already added the permission. And there is two problems, 1 it says the telecom binding permission is for system app only, And I've added android name as io. flutter. Wazo.....

As said in pub.dev doc. Still it just opens the app and not showing the accept screen

[muhammedrashidm]

[muhammedrashidm]

it says the io.wazo.callkeep.voiceCo.... class dose not available

[xyzbilal]

I assume you added Application.java according to firebase_messaging instructions. Because background message is a different isolate and runs as I service, you should make modifications in android side.

first modify Application. java according to your project. I share mine as example

package yourpackename;

import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService;
import io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin;
import com.github.cloudwebrtc.flutter_callkeep.FlutterCallkeepPlugin;
import io.flutter.plugins.pathprovider.PathProviderPlugin;
import fr.g123k.flutterappbadger.FlutterAppBadgerPlugin;
public class Application extends FlutterApplication implements PluginRegistrantCallback {

    @Override

    public void onCreate() {
        super.onCreate();
        FlutterFirebaseMessagingService.setPluginRegistrant(this);
    }

    @Override
    public void registerWith(PluginRegistry pluginRegistry) {

        FirebaseMessagingPlugin.registerWith(pluginRegistry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
        FlutterCallkeepPlugin.registerWith(pluginRegistry.registrarFor("com.github.cloudwebrtc.flutter_callkeep"));
        PathProviderPlugin.registerWith(pluginRegistry.registrarFor("io.flutter.plugins.pathprovider"));
        FlutterAppBadgerPlugin.registerWith(pluginRegistry.registrarFor("fr.g123k.flutterappbadger"));
    }
}

add firebase dependency to /android/app/build.graddle

dependencies {

    implementation 'com.google.firebase:firebase-messaging:21.0.1'

}

check if belov permissons are added to AndroidManifest. xml

  <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
    <uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />

    <uses-permission android:name="android.permission.BIND_TELECOM_CONNECTION_SERVICE"/>
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.CALL_PHONE" />

ıt must work properly then

[muhammedrashidm]

this is application.java . as you see most of the imports including the callkeep are not used, if i am wrong, i am a beginer. why there is errors and still firebase messaging works basically. and the call keep is not working

[muhammedrashidm]

![Uploading manifest error call keep 2.PNG…]()

[muhammedrashidm]

this is the what i am getting after running it. the printed "Display incoming call Now " if from a function in call keep setup, in th official example,

[muhammedrashidm]

Wen app is in background, it opens the home screen, and in run tab:-

add firebase dependency to /android/app/build.graddle

dependencies {

    implementation 'com.google.firebase:firebase-messaging:21.0.1'

}

You can do this now so keep up to date with versions:

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    // As per https://firebase.google.com/docs/cloud-messaging/android/client
    // Import the BoM for the Firebase platform
    implementation platform('com.google.firebase:firebase-bom:26.7.0')

    // Declare the dependencies for the Firebase Cloud Messaging and Analytics libraries
    // When using the BoM, you don't specify versions in Firebase library dependencies
    implementation 'com.google.firebase:firebase-messaging'
    implementation 'com.google.firebase:firebase-analytics'
}

Hi! Have you solved issue?

[muhammedrashidm]

Hi! Have you solved issue?

Not yet, The problem is the myBGMH function is on another Thread, Not in the main Flutter Activity. Do You Have any updates?

[shreyansh2211]

I am also facing same issue, have anyone found the solution?

[ScottLee97]

Hi! Try to add

 <uses-permission android:name="android.permission.BIND_TELECOM_CONNECTION_SERVICE" />
 <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
 <uses-permission android:name="android.permission.READ_PHONE_STATE" />
 <uses-permission android:name="android.permission.CALL_PHONE" />
 <uses-permission android:name="android.permission.RECORD_AUDIO" />

and

        <service android:name="io.wazo.callkeep.VoiceConnectionService"
            android:label="Wazo"
            android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE">
            <intent-filter>
                <action android:name="android.telecom.ConnectionService" />
            </intent-filter>
        </service>

to AndroidManifest

I tried @rekonvald solution and it worked. Thanks!

There are some error messages like

Class referenced in the manifest, io.wazo.callkeep.VoiceConnectionService, was not found in the project or the libraries

Permission is only granted to system apps

But I simply ignored them and close my app and restarted it. It worked thereafter.

Remember to do the callsetup stated in the callkeep documentation too.

[miracle101000]

@muhammedrashidm Hey bro, so I had the same issue as you.

I think you should make sure you add this somewhere in your app:

   final bool hasPhoneAccount = await _callKeep.hasPhoneAccount();
    if (!hasPhoneAccount) {
      await _callKeep.hasDefaultPhoneAccount(context, <String, dynamic>{
        'alertTitle': 'Permissions required',
        'alertDescription':
            'APP needs to access this permission to accept phone calls',
        'cancelButton': 'Cancel',
        'okButton': 'ok',
        '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',
        },
      })
    }

After adding the necessary permissions in your manifest file as stated above
