You can get the list of all installed apps like this :

 final List<ApplicationInfo> pkgAppsList = context.getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA);
for(ApplicationInfo app : pkgAppsList)
  {
          // here you will get all the properties of the app

           // Launch app
          Intent i=   getPackageManager().getLaunchIntentForPackage(app.packageName);
          startActivity(i);
   }
