How to listen to Boot Complete broadcast in Oneplus?

Create a BroadCastReciver class like this :

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class RebootService extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context,"Service is running", Toast.LENGTH_LONG).show();

    }
}

Define your service in AndroidManifest.

<receiver android:name=".RebootService">

    <intent-filter>


        <action android:name="android.intent.action.BOOT_COMPLETED"/>

    </intent-filter>

</receiver>

And finally :

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