NotificationListenerService 权限获取

通知监听 使用NotificationListenerService即可，但是要发送以下代码请求权限

Intent intent = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS);
    startActivity(intent);

想要不进入setting直接获取权限：

应用必须为系统应用，共享System的进程Id或者systemUI的Id应该也行，没试过，android:sharedUserId="android.uid.system"，

可以使用以下方式获取权限，不用弹出setting

/*
        获取权限BIND_NOTIFICATION_LISTENER_SERVICE
        * */
        public static void GrantNotificationListenerAccess(Context context, String packagename, String classname) {
    
            ContentResolver resolver = context.getContentResolver();
            String permissionList = Settings.Secure.getString(resolver, NOTIFICATION_LISTENER_PERMISSION_KEY);
            Log.i(TAG, "befor grand permission str = " + permissionList);
            StringBuilder serviceName = new StringBuilder(packagename);
            serviceName.append("/");
            serviceName.append(classname);
            String Service = serviceName.toString();
            if (permissionList == null) {
                permissionList = new String("");
            }
            if (permissionList != null && !permissionList.contains(Service)) {
                //权限没有获取时，添加
                StringBuilder resultBuilder = new StringBuilder(permissionList);
                if (!permissionList.equals("")) {
                    resultBuilder.append(":");
                }
                resultBuilder.append(serviceName);
                String result = resultBuilder.toString();
                Settings.Secure.putString(resolver, NOTIFICATION_LISTENER_PERMISSION_KEY, result);
            }
            Log.i(TAG, "after grand permission str = " + Settings.Secure.getString(resolver, NOTIFICATION_LISTENER_PERMISSION_KEY));
        }

例如在我的信息监听Service中，Utils.GrantNotificationListenerAccess(this,getPackageName(),getClass().getName());可以获得权限BIND\_NOTIFICATION\_LISTENER\_SERVICE

这个权限来监听系统的所有通知事件。
