How to initialize an Application class and store getApplicationContext() in android?

I have declared an Application class inside my app:

public class application extends Application {

    String TAG="joshtag";//app.TAG;

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e(TAG, "Initializing APP");
        initializeSingletons(getApplicationContext());
    }

    protected void initializeSingletons(Context c){
        Log.e(TAG, "...preparing to Initialize Singleton");
        app.initInstance(c);
    }
}

As you may imagine, I want this class to run as soon as my App launches, with the objective of initializing a Singleton class (this singleton class does not extend any other class and will contain a variable to store getAppContext). However, the Log messages never trigger inside "onCreate" and "initializeSingleton", and the Singleton is not initialized. My ultimate goal is to store a global getAppContext variable that I can use inside classes who does not inherit it. If I am approaching the issue with the wrong mindset, let me know and mention why.

Was facing the same problem. To initialise an Application class we need to specify it in manifest file with corresponding package name inside application tag.

Don't forget to add the reference to your application class in AndroidManifest.xml.

<application ... android:name="com.yourPackageName.application ">
