Android Global Variables.

Those of you familiar with android programming will be used to using intents to pass data from activity to activity but there is a much easier way of storing state information. Using a global variable class.

1. Create a class

public class GlobalVariables extends Application {

    public String sResult = "";
}

This extends the application class.

Then edit your AndroidManifest.xml file

   <application android:name="GlobalVariables" android:theme="@style/CustomTheme" android:label="@string/app_name"
                 android:icon="@drawable/icon"  >

When you want access to one of those juicy globals in your application just use:-

  GlobalVariables gb = ((GlobalVariables) getApplicationContext());
  Log.i("Test Variable is "+gb.sResult);

Simples!
