为什么Android应用程序中有“libs”文件夹？

Question

我无法理解Android下应用程序中libs文件夹的用途。

Answer 1

它是存储应用程序引用的所有库的位置

Answer 2

如果您使用第三方库，则会将jar添加到libs文件夹中。

Answer 3

If you use the Android command line to create your project, it'll default to libs/. It turns out that the Android Ant tasks are set to look in libs/ by default.

See $ANDROID_HOME/tools/ant/main_rules.xml:

<property name="jar.libs.dir" value="libs" />

If you just care about Eclipse, you can use whatever you want. It contain all the libraries referenced by your application are stored

In newer revisions of ADT (revision 17 onwards), the Ant-based build system and the Eclipse plug-in are aligned so that they behave the same way. This means, by default, only the jars that are present in the libs folder are included in the final apk file. These jars would automatically appear under "Android Dependencies" in your Eclipse project.

Answer 4

Please review the following from the android developer site:

http://developer.android.com/tools/projects/index.html#ApplicationProjects

libs/ Contains private libraries.

You can find a lot of additional helpful information there as a new developer!

Answer 5

因为Google说我们应该将jar添加到/ libs文件夹，而/ lib文件夹用于可执行文件使用的共享库文件。
