Android: What is the folder name of the jar files (LIB or LIBS)?

Solution 1:

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.

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.

Solution 2:

It doesn't matter actually. It can be lib or libs. Whether jar files are in lib or in libs, you just need to do right click on project, select "Build path => Add to build path" , thats it.
