@Nullable
@Override
public IBinder onBind(Intent intent) {

    return null;
}

@Override
public void onCreate() {
    super.onCreate();

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return super.onStartCommand(intent, flags, startId);
}

@Override
public void onDestroy() {
    super.onDestroy();

}

private void createChannel(){
}

private void sendNotification(String title,String content){

}
}

In StartNotificationReceiver.java

package com.ecsoft.zyymaintain.service;

public class StartNotificationReceiver extends BroadcastReceiver {


static final String ACTION = "android.intent.action.BOOT_COMPLETED";

@Override
public void onReceive(Context context, Intent intent) {
    Log.e(“sot”,”onReceive:"+intent.getAction());
    if (ACTION.equals(intent.getAction())){ 
        Intent intentService = new Intent(context, NotificationService.class);
        context.startService(intentService);
    }
