you are not wrong ? Best use of hard-coded , rear aspect also maintenance .

/ / check all the applications already installed
List listAppcations = pm
. getInstalledApplications ( PackageManager.GET_UNINSTALLED_PACKAGES );
Collections.sort (listAppcations,
new ApplicationInfo.DisplayNameComparator (pm)) ;/ / Sort
List appInfos = new ArrayList (); / / save the filter found in AppInfo
