Read preference of other application android

i've read that shared preferences can be retrieved from outside my application . this code did not work:

try 
{
    myContext = createPackageContext("com.intervigil.micdroid", Context.MODE_WORLD_WRITEABLE); // where com.example is the owning  app containing the preferences
    SharedPreferences testPrefs = myContext.getSharedPreferences("test_prefs", Context.MODE_WORLD_READABLE); 
    Map<String, ?> items = testPrefs.getAll();
    nbenroullement= (Integer) items.get("enroullement");
    System.out.println("*********************" + nbenroullement);
} 
catch (NameNotFoundException e) 
{
    e.printStackTrace();
}

Please can any one help me . Thank you

That's probably because you aren't itereting the Maps items. So, try to do something like that : 

Map<String, ?> items = testPrefs .getAll();
for(String s : items.keySet()){
    String value =  items.get(s).toString()); //this is the key of preferences

}

Once you retrieve the key (enroullement, I presume) you got to use it like this : 

enroullement = Integer.valueOf(prefs.getString("enroullement", "0")); //0 is a default value

Hope it helps.
