This specific permission must be granted manually by the user in android Settings, after that your service will be executed as you bound the permission to your service in AndroidManifest.xml with this:

    <service android:name=".PcNotification"
    android:label="PCNotificationService"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" />
        </intent-filter>
    </service>

The problem is that most users won't know where to grant this permission (e.g inside android Settings), so you can open it for them with this:

    startActivity(new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"));

From the documentation on how we Inject dependencies into Android classes, we can learn the following:

Hilt can provide dependencies to other Android classes that have the @AndroidEntryPoint annotation.

Hilt currently supports the following Android classes:

Application (by using @HiltAndroidApp) ViewModel (by using @HiltViewModel) Activity Fragment View Service BroadcastReceiver

So when you subclass any of these Android classes, you don't ask Hilt to inject dependencies through the constructors. Instead, you annotate it with @AndroidEntryPoint, and ask Hilt to inject its dependencies by annotating the property with @Inject:

    @AndroidEntryPoint
    class ExampleActivity : AppCompatActivity() {
    
        @Inject
        lateinit var mAdapter: SomeAdapter 
        ...
    }

So, in your case you should inject MyRepository in MyActivity and MyService like this:

    @AndroidEntryPoint
    class MyService: Service() {
    
        @Inject
        lateinit var myRepository: MyRepository
        ...
    }
    
    @AndroidEntryPoint
    class MyActivity: AppCompatActivity(R.layout.my_layout) {
    
        @Inject
        lateinit var myRepository: MyRepository
        ...
    }

And remember:

Fields injected by Hilt cannot be private

That's it for Android classes that is supported by Hilt.

If you wonder what about classes not supported by Hilt (ex: ContentProvider)?! I recommend learning how from this tutorial @EntryPoint annotation on codelab (also don't forget to check the documentation for how to Inject dependencies in classes not supported by Hilt).

If you're working with Android 7.0+, WhatsApp uses MessageStyle Expanded Notifications. Here - https://developer.android.com/training/notify-user/expanded.html#message-style

To retrieve all 5 messages from a notification like

MyFriend (5 messages) testt

Do this:

    Bundle extras = mysbn.getNotification().extras;
    if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)){
    Parcelable b[] = (Parcelable[]) extras.get(Notification.EXTRA_MESSAGES);
    
            if(b != null){
                content = "";
                for (Parcelable tmp : b){
    
                    Bundle msgBundle = (Bundle) tmp;
                    content = content + msgBundle.getString("text") + "\n";
    
                    /*Set<String> io = msgBundle.keySet(); // To get the keys available for this bundle*/
    
                }
            }
        }
