do you want to check permission level of installed package ? If yes then check this API developer.android.com/reference/android/content/pm/…

You can use PackageManager class getPermissionInfo() method to get PermissionInfo object for any particular permission. PermissionInfo object has property Protection Lavel that can be used to check the protection level of any permission. You can check it against the constant defined in the PermissoinInfo class like PROTECTION_FLAG_SYSTEM .

Like following code :

for (PermissionInfo permission : packageInfo.permissions) < // Dump permission info String protectionLevel; switch(permission.protectionLevel) < case PermissionInfo.PROTECTION_NORMAL : protectionLevel = "normal"; break; case PermissionInfo.PROTECTION_DANGEROUS : protectionLevel = "dangerous"; break; case PermissionInfo.PROTECTION_SIGNATURE : protectionLevel = "signature"; break; case PermissionInfo.PROTECTION_SIGNATURE_OR_SYSTEM : protectionLevel = "signatureOrSystem"; break; default : protectionLevel = ""; break; > Log.i("PermissionCheck", permission.name + " " + protectionLevel); >

UPDATE:

To get the Protection level of requestedPermissions :

String[] reqp = info.requestedPermissions; String perm = reqp[i]; if (perm.contains("android.permission.")) < try < PermissionInfo pi = getPackageManager().getPermissionInfo(perm, PackageManager.GET_META_DATA); String protctionLevel = "unknown"; switch(pi.protectionLevel) < case PermissionInfo.PROTECTION_NORMAL : protctionLevel = "normal"; break; case PermissionInfo.PROTECTION_DANGEROUS : protctionLevel = "dangerous"; break; case PermissionInfo.PROTECTION_SIGNATURE : protctionLevel = "signature"; break; case PermissionInfo.PROTECTION_SIGNATURE_OR_SYSTEM : protctionLevel = "signatureOrSystem"; break; case PermissionInfo.PROTECTION_FLAG_SYSTEM : protctionLevel = "system"; break; default : protctionLevel = ""; break; > list_permission.add(perm + " "+protctionLevel); > catch (NameNotFoundException e) < // TODO Auto-generated catch block e.printStackTrace(); >> else

Following line would only work on API level 16 or above:

 case PermissionInfo.PROTECTION_FLAG_SYSTEM : protctionLevel = "system"; break;
