Most of it seems to be disclosing your use of the library and making sure you adhere to the rules of distribution according to the license.

blocks|key|797722|text|我一直认为LGPL是一个非常“灰色地带”。虽然有关于如何使用LGPL代码/库等的细节，但它不一定反映作者的确切要求。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|797723|就我个人而言，我建议联系作者，解释你的担忧，并询问他们是否乐于允许你使用它。|797724|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|$]]

I've always thought LGPL was very much a 'grey area'. Although there are specifics on how LGPL code/libraries etc should be used, it doesn't necessarily reflect the exact requirements of the author(s).

Personally I would recommend contacting the author(s), explaining your concerns and asking if they are happy to allow you to use it.

blocks|key|797800|text|如果你在做一个付费的安卓应用，你可能会遇到LGPL的一个特定问题:可替代性。通常，它规定，当您发布组合作品时，您必须为用户提供用不同版本(例如较新版本)替换库的可能性。在DEX文件的情况下，非常值得怀疑，如前面的评论所述。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|797801|一种替代单个DEX文件的方法是从依赖库中创建一个单独的应用程序，该应用程序在LGPL上发布。在这样的应用程序中，您可以创建一个从付费应用程序连接到的服务。然后，要用新版本替换LGPL库，只需重新编译和重新安装库的APK即可。|797802|当然，麻烦的是，现在您需要安装多个APK。|797803|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

If you're making a paid Android app you'll probably have problems with a specific issue of LGPL: substitutability. Generally, it states that when you distribute a combined work you have to provide a user with possibility to substitute the library with a different version (e.g. newer). Very doubtful in the case of DEX file, as mentioned in previous comments.

An alternative to a single DEX file is to make from a dependent library a separate application, released on LGPL. In such an application you create a service to which you connect from your paid application. Then, to substitute the LGPL library with newer version only recompilation and reinstalling the library's APK is required.

The hassle is, of course, that now you have more than one APK to install.

blocks|key|1012129|text|droidText库(用于在Android上导出为PDF格式，并在LGPL下发布)详细解释了如何使用他们的库并仍然符合LGPL：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1012130|http://code.google.com/p/droidtext/wiki/LGPLCompliance|offset|length|1012131|我发现它很有帮助。基本上，您使用一个实用程序(dex2jar)将库的jar从dex文件中取出-这样，如果他们愿意的话，允许和最终用户使用较新版本的droidText库进行更新。|1012132|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1I|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@$D|Q|E|R|1|S]]|A|$]]|$1|F|3|G|5|6|7|T|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|C]]]]

The droidText library (used for exporting to PDF format on Android and released under LGPL) has a detailed explanation of how to use their library and still comply with the LGPL:

<a href="http://code.google.com/p/droidtext/wiki/LGPLCompliance">http://code.google.com/p/droidtext/wiki/LGPLCompliance</a>

I found it very helpful. Basically you use a utililty (dex2jar) to take the jar of the library OUT of the dex file- thus allowing and end user to update with a later version of the droidText library if they want to.

Can I use a LGPL library in my paid android application? I am not going to modify the LGPL lib, I just want to use it. Is it legal?
