for (int i = 0; i < usespermissionsarray.length; i++) {

Get the name of each permission, such as: Android.permission.INTERNET

String Usespermissionname=usespermissionsarray[i];

System.out.println ("usespermissionname=" +usespermissionname);

Get the details of this permission through Usespermissionname

Permissioninfo permissioninfo=packagemanager.getpermissioninfo (usespermissionname, 0);

Obtain which permission group this permission belongs to, such as: network traffic

Permissiongroupinfo permissiongroupinfo = packagemanager.getpermissiongroupinfo (permissionInfo.group, 0);

System.out.println ("permissiongroup=" + Permissiongroupinfo.loadlabel (Packagemanager). toString ());

Gets the label information for the permission, for example: Full network access

String Permissionlabel=permissioninfo.loadlabel (Packagemanager). toString ();

System.out.println ("permissionlabel=" +permissionlabel);

Gets a detailed description of the permission, such as: Allow the application to create a network socket and use a custom network protocol

Browsers and other applications provide a way to send data to the Internet, so applications can send data to the Internet without this permission.

String permissiondescription=permissioninfo.loaddescription (Packagemanager). toString ();

System.out.println ("permissiondescription=" +permissiondescription);

System.out.println ("===========================================");
