You can Find the List of installed apps in Android Device by using below code, "packageInfo" Contains Installed Application Information in Device. we can retrive Intent for the application installed from the packageinfo object and by using startactivity(intent), can start application. it is up to you how you organize the UI either Listview or Gridview. so on click event based on position, you can retrive intent object and start activity intent.

final PackageManager pm = getPackageManager();

List packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);


for (ApplicationInfo packageInfo : packages) 

{
 if(pm.getLaunchIntentForPackage(packageInfo.packageName)!= null &&   

                   !pm.getLaunchIntentForPackage(packageInfo.packageName).equals(""))


{

    System.out.println("Package Name :" + packageInfo.packageName);

    System.out.println("Launch Intent For Package :"   +  
                  pm.getLaunchIntentForPackage(packageInfo.packageName));

    System.out.println("Application Label :"   + pm.getApplicationLabel(packageInfo));

    System.out.println("Application Label :"   + 
                           pm.getApplicationIcon(packageInfo.packageName).toString());

    System.out.println("i : "+i);

    /*if(i==2)

    {
         startActivity(pm.getLaunchIntentForPackage(packageInfo.packageName));

     break;

    }*/

    i++;

}
