Getting the Application Context

Question

This might be a simple question but I just wanted to make sure I am right.

In my android application I have a constructor that uses:

activity.getApp         


        

Answer 1

The easiest way to get the application context is:

Create a class App that extends android.app.Application

public class App extends Application {
    public static Context context;

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

Modify your AndroidManifest.xml 's tag to have the attribute android:name="your.package.name.App".

Any time you need the application context, just get it from App.context.

Application is always initialized first whether your process runs, whether it's an activity, a service, or something else. You will always have access to the application context.
