getLaunchIntentForPackageがアプリの場合はnull

Question

1. インストールされているアプリケーションを警告グリッド表示でビルドしています。私は いくつかのお気に入りのアプリを選択していて、その後に別のグリッドビューを追加している場合 新しいGridviewアプリからアプリを選択すると、そのインテント値（getLaunchIntentForPackage）がnullです。

   quick_links_alert.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int whichButton) { 
         List<String> mArrayProducts = clad.getCheckedItems(); 
         final QuickLinksGridViewAdaptor selected_apps = new QuickLinksGridViewAdaptor(HomeActivity.this, mArrayProducts); 
         gv_shortcut.setAdapter(selected_apps); 
         Toast.makeText(getApplicationContext(),"Selected Items-->:"+mArrayProducts,Toast.LENGTH_LONG).show(); 
         PackageManager pm = HomeActivity.this.getPackageManager(); 
         Intent quick_intent = new Intent(Intent.ACTION_MAIN, null); 
         final List<ResolveInfo> list = pm.queryIntentActivities(quick_intent, PackageManager.PERMISSION_GRANTED); 
         gv_shortcut.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
          @Override 
          public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
           final String packageName = list.get(position).activityInfo.packageName; 
           Intent PackageManagerIntent = getPackageManager().getLaunchIntentForPackage(packageName); 
           if (PackageManagerIntent != null) { 
            startActivity(PackageManagerIntent); 
           } 
           else { 
            Toast.makeText(getApplicationContext(),"NULL",Toast.LENGTH_LONG).show(); 
           } 
          } 
         }); 
        }

私は、問題を解決した：

String s = mArrayProducts.get(position).getPackageName(); 
Intent PackageManagerIntent = getPackageManager().getLaunchIntentForPackage(s); NULL 
startActivity(PackageManagerIntent);
