        List<PackageInfo> packageInfo = pm.getInstalledPackages(PackageManager.GET_PERMISSIONS);

            String[] requestedPermissions = info.requestedPermissions;
            if (requestedPermissions != null) {
                for (String permission : requestedPermissions) {
            if ("your_manifest_permission".equals(permission)) {
