While consumers bypassing the marketplace and copying a free app will obviously not directly affect profits, keeping track of the number of people using your app can be very important in terms of building the reputation both of the app itself and of your company / you as an indie developer.

If your app communicates with a server or central database as part of its natural functionality, then usage tracking can be implemented through that channel. But if not, then download information on the marketplace is the next best way to get a rough estimate of its popularity.

As for security, I'm not aware of any way forward locking directly makes your app more secure, preventing illicit copying could certainly serve to discourage untoward manipulation of the package files.

blocks|key|2245916|text|不，但它并不是特别受保护-无论应用程序开发人员喜欢什么，它都可以从大多数android手机上复制所有数据，一旦你有了字节，你就可以反汇编成你的核心内容。(您的特定应用程序是否可能发生上述情况是一个完全不同的问题)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2245917|锁定它还有其他原因--更准确地计算用户群，等等--但它们通常不值得对整体用户体验造成影响。如果您的应用程序偶尔给家里打电话统计已安装的手机数量，这比试图强制执行某种方式来信任Marketplace计数要好得多。|2245918|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

No, but it isn't particularly protected either way - it's possible to copy all the data off most android phones regardless of what the application developer would prefer, and once you have the bytes you can disassemble to your hearts' content. (Whether any of that is likely to happen to your particular application is an entirely different question).

There are other reasons to lock it - more accurate counting of userbase, etc. - but they're generally not worth the impact to the overall user experience. If your app phones home occasionally to count installed handsets, that's a much better plan than trying to enforce some way to trust the Marketplace count.

blocks|key|1388533|text|所谓“转发锁”，我假设你的意思是“防止用户将应用程序转发给另一个人”，而所谓的“免费”，我假设你的意思是“零钱可用”。如果是这样的话，是的，有理由这样做。首先，这将确保应用程序只能从单一来源获得，用户不必担心应用程序是真的还是被篡改的版本。有人使用免费提供的应用程序，添加自己的广告或恶意代码，然后重新分发应用程序，就像它是原始版本一样，这并不是闻所未闻的。毫无戒心的用户最终会在不知情的情况下运行广告软件/恶意软件。这也(不公平地)给最初的应用程序带来了坏名声。因此，许多免费应用程序阻止转发/复制的唯一原因是确保真实性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1388534|此外，仅仅因为一个应用程序不花费任何费用并不意味着它里面没有商标/版权保护的材料(或其他类型的受保护的知识产权)，这些材料是不可合法复制的。能够轻松地复制或拆卸应用程序可能会使创建者面临法律问题(特别是如果他们从第三方获得了一些内容的许可)，因此免费的应用程序不一定能够被拆分。也就是说，二进制代码总是可以在十六进制编辑器中查看的，如果你有时间和耐心，任何东西都可以被分解……|1388535|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

By "forward lock" I'm assuming you mean "prevent a user from forwarding the app to another person", and by "free" I'm assuming you mean "available for zero money". If that is the case, then yes, there are reasons to do so. First and foremost, this will ensure that the app is only available from a single source and that users don't have to worry about whether the app is genuine or a tampered version. It is not unheard of for someone to take a freely available app, add their own ads or malicious code, and re-distribute the app as if it was the original version. Unsuspecting users end up running adware/malware without knowing it. This also (unfairly) gives the original app a bad reputation. Therefore, many free apps prevent forwarding/copying for the sole reason of ensuring authenticity.

Also, just because an app does not cost anything doesn't mean that there aren't trademarked/copyrighted materials (or other types of protected intellectual property) inside it that aren't legally copy-able. Being able to easily copy or dis-assemble the app could open the creator to legal issues (especially if they licensed some of their content from a third party), so a free app isn't necessarily able to be taken apart. That being said, binary code is always viewable in a hex editor, and anything can be dis-assembled if you have the time and patience...

blocks|key|639724|text|没有办法保护任何东西不被反编译。除非没有可以运行它的平台。但你可以让它变得更难，使用混淆之类的东西。但对于一个免费的应用程序来说，这可能不值得你花这么大力气。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|639725|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

There's no way to protect anything from decompilation. Except if there's no platform that can run it.
But you can make it harder, with obfuscation and stuff.
But fo a free app it is probably not worth the effort.

blocks|key|1384555|text|不，因为Android+Market提供的实现是多重破坏的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1384556|安卓应用市场版权保护并不能阻止盗版，因为有扎根手机的人仍然可以进入并获取APK，就像他们一直在做的那样(而且，AFAIK，它不会阻止decompilation)|1384557|Using+|unordered-list-item|1384558|版权保护有时会让你的应用程序被市场拒之门外，例如当新设备推出时|1384559|1384560|1384561|如果你想要版权保护，那是你的决定，但使用Android市场提供的以外的东西。|1384562|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$]]|$1|G|3|H|5|F|7|R|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|S|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

No, because the implementation that the Android Market offers is multiply broken:

<ul>
<li>It does not stop piracy, as people with rooted phones can still go in and grab the APKs, as they do all the time (and, AFAIK, it does nothing to stop decompilation)</li>
<li>Using Android Market copy protection has a tendency to keep your app out of the Market on occasion, such as when new devices are being rolled out</li>
</ul>

If you want copy protection, that's your call, but use something other than the one supplied by the Android Market.

Is there any reason to forward lock a free app? If the user copies the app from the phone, is it protected in any way from decompilation, etc?

Any reason at all to forward lock a free app?
