如何每分钟在Android O中运行后台服务？

Question

I have an old application in which the service was invoked using the AlarmManager 's setExact every minute, but in the latest Android O , it is not allowing me to run the service in the same way. I couldn't use foreground service because I don't want to show any notification when my service is running.

I want help on tweaking my application architecture in a way so that my code should run in the Android O with minimum changes.

When I run my application in the Android, it is crash:(.Please find the stack trace of the crash below.

java.lang.RuntimeException: Unable to create application com.***.***.***ControllerApplication: java.lang.IllegalStateException: Not allowed to start service Intent

Caused by: java.lang.IllegalStateException: Not allowed to start service Intent { cmp=com.***.***.qa/com.***.***.services.AlarmService

Edit:

The task in my application is time critical therefore I used setExact in AlarmManager but none of the currently supported APIs is scheduling jobs at an exact time. With that said, If I use JobScheduler/ WorkManager then my application will malfunction.

You can use the Alarm manager which will be called after every 10 mins

        AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        Random random = new Random();
        int m = random.nextInt(9999 - 1000) + 1000;

        Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
        notificationIntent.setClass(this,AlarmReceiver_.class);
        notificationIntent.addCategory("android.intent.category.DEFAULT");

        PendingIntent broadcast = PendingIntent.getBroadcast(YourClass.this, r5, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                SystemClock.elapsedRealtime() + 300000L,
                600000L, broadcast);

ManiFest receiver Code where you will get a receiver response

<receiver android:name="com.yourpackage.AlarmReceiver_"

        >
        <intent-filter>
            <action android:name="android.media.action.DISPLAY_NOTIFICATION" />
            <category android:name="android.intent.category.DEFAULT" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
            <action android:name="android.intent.action.REBOOT" />
            <action android:name="android.intent.action.BOOT_COMPLETED" />

        </intent-filter>
    </receiver>

You will have to create Receiver where you will receive data as an above-specified name of AlarmReceiver_.class
