Get Context in a Service

just in case someone is getting NullPointerException, you need to get the context inside onCreate().

Service is a Context, so do this:

private Context context;

@Override
public void onCreate() {
    super.onCreate();
    context = this;
}

Note:

Read: "Do not place Android context classes in static fields; this is a memory leak (and also breaks Instant Run)" Do you know what context classes are? Activity is one of them, and you should not store Activity as a static field, (or it will leak memory). However, you can store Context (as long as it is the application context) as a static field, since it outlives everything.

1. Service extends ContextWrapper
2. ContextWrapper extends Context

So....

Context context = this;

(in Service or Activity Class)

Service is a Context

Service extends ContextWrapper which extends Context. Hence the Service is a Context. Use 'this' keyword in the service.
