As swayam suggested, i will suggest you yo go for a DB or Shared prefs, Especially Shared prefs suits best for your scenario;

You can use something like as follows:

To Put:

SharedPreferences sharedPreferences = getSharedPreferences("PREFS_READ",
                Context.MODE_WORLD_READABLE);
        Editor prefsPrivateEditor = sharedPreferences.edit();
        prefsPrivateEditor.putString("yourkey", userName);
prefsPrivateEditor.commit();

To Get:

SharedPreferences sharedPreferences;
        Context otherAppsContext = null;
        try {
            otherAppsContext = getApplication().createPackageContext(
                    "your.package.name", 0);
        } catch (NameNotFoundException e) {
            Toast.makeText(Email.this, e.toString(), Toast.LENGTH_LONG).show();
        }
        sharedPreferences = otherAppsContext.getSharedPreferences("PREFS_READ",
                Context.MODE_WORLD_WRITEABLE);

        String getusername = sharedPreferences.getString("yourkey","default_value");
