here input te function arraylist of permissions corresponding group needs found. getting pm.getpermissiongroupinfo(entry,0) null. dont know mistake. pls correct me.

thanks in advance.

to "short name" example "location" can use

packagemanager packagemanager = getapplicationcontext().getpackagemanager(); permissioninfo permissioninfo = packagemanager.getpermissioninfo(manifest.permission.access_fine_location, 0); permissiongroupinfo permissiongroupinfo = packagemanager.getpermissiongroupinfo(permissioninfo.group, 0); log.w("11_app", ""+permissiongroupinfo.loadlabel(packagemanager));
