android – Store application global data-ThrowExceptions

Exception or error:

What is the best way to store global objects/instances through out the application ?

How to solve:

Here is the following code which I use to store String in Application Context.

I make the class


public class GlobalVariable extends Application 
      private String myState;

      public String getState()
        return myState;
      }//End method

      public void setState(String s)
        myState = s;
      }//End method
}//End Class

In .Manifest I add the following code

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

Where I want to set the value of string I use the following code

GlobalVariable appState = ((GlobalVariable)getApplicationContext());

& where I want to Retrive the data I use

GlobalVariable appState = ((GlobalVariable)getApplicationContext());


Extend the Application object and store the references to your global objects in it.


What about Singleton pattern?
