In the "source" activity do this:

SharedPreferences settings = context.getSharedPreferences(
"yourfilename.bla", Context.MODE_PRIVATE);

SharedPreferences.Editor editor = settings.edit();

editor.putString("key", value);
editor.commit();


In the target activity do this:

SharedPreferences preferences = getSharedPreferences(
"yourfilename.bla", Context.MODE_PRIVATE);

String value= preferences.getString("key", "");


The second parameter in getString is the default value you want returned if "key" isn't found.
