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.

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