Adding libraries without resources

 

  1. Make sure you have downloaded the Android Support Library using the SDK Manager.
  2. Create a ​​libs/​​ directory in the root of your application project.
  3. Copy the JAR file from your Android SDK installation directory (e.g., ​​<sdk>/extras/android/support/v4/android-support-v4.jar​​) into your application's project ​​libs/​​ directory.
  4. Right click the JAR file and select Build Path > Add to Build Path.

 

Adding libraries with resources

参考setup文档,要先建立一个library project,然后再引用这个project
