如何在Android中过滤用户安装的应用程序？

Question

I am creating a method to displays the installed applications in android. I gave the following lines of code to get the application list

PackageManager packageManager=this.getPackageManager(); 
        List<PackageInfo> applist=packageManager.getInstalledPackages(0);
        Iterator<PackageInfo> it=applist.iterator();
        while(it.hasNext())
            {
                PackageInfo pk=(PackageInfo)it.next();
                    if(PackageManager.PERMISSION_GRANTED==packageManager.checkPermission(Manifest.permission.INTERNET, pk.packageName)) //checking if the package is having INTERNET permission
                        {
                            //some processing
                        }
            }
}

Here everything is working fine but the list includes the system packages too. I need to get only the list of user installed packages. Is there any way to do??

What flag should we set in getInstalledPackages() to get the user installed packages?

如果已将ApplicationInfo对象安装在固件上，则它将具有FLAG_SYSTEM ，因此您可以使用它来过滤掉那些对象。
