I need to start a service when the device starts up. I have searched the Internet and I have implemented what is necessary, but I get an error and I can not solve it, try not to start a service but an activity and it works then I do not know what may be happening.

Monitor Class

    public class Monitor extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        /*Intent i = new Intent(context, MainEventos.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);*/
        Intent service = new Intent(context.getApplicationContext(),  ServicioNotificaciones.class);
        context.startService(service);
    }
}

Android Manifest

  <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<application
    android:allowBackup="true"

Swagger-ui throws the error "TypeError: property is undefined" when rendering the file swagger.json How to generate report in Jasper if the WHERE condition is not met

To start a service when you turn on your device:

You are already doing this when defining the action to your BroadcastReceiver that is the one that starts the service, only add android:enabled="true" and permission android:permission="android.permission.RECEIVE_BOOT_COMPLETED" :

<receiver android:enabled="true" android:name=".Monitor" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

Remember that the full initialization ( BOOT_COMPLETED ), is done a few seconds after you see the device turned on.

I add a example of a service that starts on power up the device.

Regarding the error:

java.lang.RuntimeException: Unable to start receiver com.example.alex_.girardotaeventos.Monitor: java.lang.IllegalStateException: Not allowed to start service Intent { cmp = com.example.alex_.girardotaeventos / .ServicioNotificaciones}: app is in background uid UidRecord {5dec8da u0a103 RCVR idle procs: 1 seq (0,0,0)}

The Monitor class is the BroadcastReceiver that starts the service,

public class Monitor extends BroadcastReceiver {

and the service is class ServicioNotificaciones :

public class ServicioNotificaciones extends Service {

The problem is that the intent-filter BOOT_COMPLETED must be defined for the BroadcastReceiver but for the service you should not have it defined, delete that part :

<receiver android:enabled="true" android:name=".Monitor" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
   <service android:enabled="true" android:name="com.example.alex_.girardotaeventos.ServicioNotificaciones"
    android:exported="true">
   </service>

The BroadcastReceiver (class Monitor ) must be the one that starts the service , which is correct.

  @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context.getApplicationContext(),  ServicioNotificaciones.class);
        service.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startService(service);
    }
