NullPointerException while trying to create a new intent in WakefulBroadcastReceiver after reboot

Question

I have written a subclass of WakefulBroadcastReceiver that receives the "android.intent.action.BOOT_COMPLETED" action when user device is rebooted.

It is working fine in my Nexus device but not on some other devices like Samsung, Verizon etc. For those devices, I am getting a NullPointerException in onReceive() at this line Intent service = new Intent(context, MyAlarmOnBootService.class); as

java.lang.RuntimeException: Unable to start receiver com.android.myapp.receiver.MyWakefulAlarmOnBootReceiver: java.lang.NullPointerException

This is my receiver class:

public class MyWakefulAlarmOnBootReceiver extends
        WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.d("MyApp", "receiver started after reboot");                

        Intent service = new Intent(context, MyAlarmOnBootService.class);//this is the line where I am getting NPE.
        service.putExtras(intent.getExtras());

        startWakefulService(context, service);
    }

}

My Manifest file (only the parts related are shown in this file):

<?xml version="1.0" encoding="utf-8"?>
    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="25" />

    <service

Is this related to Smart Manager app of Samsung that kills apps and alarms? If yes, how is my receiver fired? Is there some problem in the context parameter in onReceive()? Please help me. It is working fine on my Nexus 5.

Answer 1

Intent service = new Intent(context, MyAlarmOnBootService.class);//this is the line where I am getting NPE.

actually this is not the line. the exception raised from next line

service.putExtras(intent.getExtras());

you created new intent which has no extras, and you pass it as a parameter to putExtra() this is where you are wrong.
