Question

I have created some business objects which are created with the data from the database. I am doing this so that I don’t want to hit the DB again and again. The business objects implements parcelable interface. So I can put the arraylist of business objects to the next activity. I am using APILevel 8 so there is no point of using SharedPreferences.editor putExtraSet. Even if I am using API level 11 or above. PutExtraSet can have only set of Strings.

How can I make the arrayList or some collection of business objects available for the entire application rather than forwarding from one activity to another?

Thanks in advance for your help.

Answer 1

Extend the Application class.

class SomeName extends Application{

    private Object obj;
    public Object getObj(){
        return obj;
    }
    public void onCreate(){
        super.onCreate();
    }
}

The application class is global to your application and can be accessed by any activity by calling

((SomeName)getApplication).getObj();

or just keep a reference in you Activity if you use it a lot

SomeName someName = (SomeName)getApplication();
someName.getObj();

In the androidManifest.xml the following has to be done.

<application android:icon="@drawable/icon" android:label="@string/app_name" android:name="SomeName">
