android - 如果我在我的 Android 应用程序中使用 3rd 方库，我应该把许可证放在哪里

Question

我在我的 github android 应用程序中使用了一些第 3 方库(例如 https://github.com/Clans/FloatingActionButton)。这是在 Apache 许可下，版本 2.0。我的问题是我应该在我的应用程序中放置许可证，它应该对最终用户可见吗？是否需要在我的应用中添加 libaray 许可证？

Answer 1

首先，在这种情况下，该库的所有者忘记将日期和他的名字添加到 Apache 许可文本文件中。

基本上，您必须服从版权所有者希望您做的事情。这可能意味着您不需要向项目中添加任何内容。参见例如 Terms of Service的 Pixabay :

You are free to adapt and use them for commercial purposes without attributing the original author or source. Although not required, a link back to Pixabay is appreciated.

如果版权所有者使用许可证，您必须遵守许可证告诉您的内容。这可能因许可证而异。如果是 Apache 许可证，请参阅 this information :

It allows you to: freely download and use Apache software, in whole or in part, for personal, company internal, or commercial purposes. use Apache software in packages or distributions that you create.

It forbids you to: redistribute any piece of Apache-originated software without proper attribution; use any marks owned by The Apache Software Foundation in any way that might state or imply that the Foundation endorses your distribution. use any marks owned by The Apache Software Foundation in any way that might state or imply that you created the Apache software in question.

It requires you to: include a copy of the license in any redistribution you may make that includes Apache software. provide clear attribution to The Apache Software Foundation for any distributions that include Apache software.

It does not require you to: include the source of the Apache software itself, or of any modifications you may have made to it, in any redistribution you may assemble that includes it. submit changes that you make to the software back to the Apache Software Foundation (though such feedback is encouraged).

顺便说一句:为了安全起见，我总是会做些什么。我的应用程序“法律声明”中有一个链接，用户可以在其中查看我使用的所有许可证。就算我用pixabay的图片。我也把这些信息放在那里。实际上，免费使用他人的作品是你最起码可以做的事情。如果有人像您一样忘记添加他的凭据，我会在将其放入我的应用程序时将他的名字添加到许可证文件中。否则许可证毫无值(value)。
