获取桌面应用

获取桌面应用的关键点：

1.  ResolveInfo

2. new intent: Intent intent = new Intent(Intent.ACTION_MAIN, null);

                        intent.addCategory(Intent.CATEGORY_LAUNCHER);

代码如下：

public static List<ResolveInfo> getShortcutApps(Context context) {
PackageManager pm = context.getPackageManager();


Intent intent = new Intent(Intent.ACTION_MAIN, null);

   intent.addCategory(Intent.CATEGORY_LAUNCHER);  

     
   List<ResolveInfo> infoList = context.getPackageManager().queryIntentActivities(intent,PackageManager.GET_ACTIVITIES);
   
   //去掉重复项目
   HashSet h = new HashSet(infoList);
   infoList.clear();
   infoList.addAll(h);
   
    //get data
   for (ResolveInfo info: infoList) {
    String lableName = (String) info.loadLabel(pm);
    String pkgName = info.activityInfo.packageName;  


            String publisher = info.activityInfo.applicationInfo.publicSourceDir;
           
            
   }


   return infoList ;


}
