安卓LVL合理吗？
我即将发布我的第一个 Android 应用程序。
我正在考虑为我的应用程序使用 Android 的许可服务 (LVL)。但现在我不确定不使用任何许可服务是否会更好。
- a) LVL 无论如何都可以破解
- b) LVL 导致我的应用程序出现一些延迟
你们觉得怎么样？！您有使用/不使用 LVL 的经验吗？ 我还有其他选择吗？！
谢谢
I am about to release my first firsion of an android app.
I was thinking about using android's licensing service (LVL) for my app. But now I am not sure if it wouldn't be better just not to use any licensing service.
- a) LVL can be cracked anyhow
- b) LVL causes some delay of my app
What do you guys think ?! Do you have any experience with using / not using LVL ?
Do I have any alternatives ?!
Thanks

LVL 在老练的盗版/黑客面前绝对是一坨屎，但是，它确实为您的付费应用程序提供了一些基本的保护，防止普通用户共享和使用。如果没有 LVL，您的付费应用程序是完全赤裸裸的，任何能够获取您的 apk 文件（例如，使用 root 设备）的人都可以在线共享该文件，以便其他人可以免费下载、安装和使用它。
，我认为最佳做法是在从某处下载并安装应用程序并在设备上打开应用程序时，仅在第一次时检查许可详细信息。这里有很多问题讨论如何在应用程序第一次启动时仅运行一些代码一次。
我看到有些人实施自己的保护策略并在自己的网站上发布应用程序，这可能会增加被破解的复杂性。我个人认为这没有多大帮助。您的应用程序多久会被破解完全取决于您的应用程序的受欢迎程度，有许多由最专业的公司创建的应用程序，对于其中大多数您可以轻松地在网上谷歌搜索破解版本。我知道中国有一些社区/论坛，他们创建了自己版本的市场应用程序，并且每天都有一群人盗版流行应用程序（新添加或升级），并在他们自己的假市场应用程序中发布破解版本，如果您购买了中国的三星 Galaxy Tab 带有这种假市场应用程序，您可以从这里下载最流行的应用程序/游戏。所以面对事实吧。
LVL is definitely a piece of crap in front of sophisticated pirate/hacker, however, it does provide some basic protection on your paid application from being shared and used by normal user. Without LVL, your paid application is completely naked and anyone who can get your apk file (for example, with a rooted device) can share it online so other people can download, install and use it for free.
IMO the best practice is just check the licensing details only once at the very first time when your application is downloaded and installed from somewhere, and opened on the device. there are many SO question here discuss how to run some code only once when application started first time.
I have seen some people implements their own protection strategy and publish app on their own website, which probably increase the complexity from being cracked. Personally I don't think this help much. How soon your application will be cracked is totally determined by how popular your application is, there are many application created by the most professional companies, for most of them you can easily google the cracked version online. I know there are some communities/forums in China, They created their own version of market app and have groups of people pirate popular application (newly added or upgraded) daily and publish the cracked version in their own fake market app, if you buy a Samsung Galaxy Tab in China, it comes with this kind of fake market app and you can download most popular app/games from here. So face the facts.
