  1. Export Library
    • Prepare source code
      • Create an Android project
      • Create source code, and fix all bug
      • Remove res/*
      • Remove unused source files
      • Edit AndroidManifest.xml to remove the statements that referes to resource, such as android:icon="@drwable/icon", android:label="@string/app_name"
    • Export library
      • On Package Explorer Panel of Eclipse, right-click the project, and select Export
      • Select Jave -> JAR file, then press "Next". At this time a dialog pops up.
      • On the right panel of "Select the resources to export:" group, unselect all items (such as .classpath, .project, AndroidManifest.xlm, default.properties), then press "Next"
      • Press "Next"
      • Press "Finish"

        Then the library is created.

  2. Import Library
    You can use a third party JAR in your application by adding it to your Eclipse project as follows:
    • In the Package Explorer panel, right-click on your project and select Properties.
    • Select Java Build Path, then the tab Libraries.
    • Press the Add External JARs... button and select the JAR file

    Alternatively, if you want to include third party JARs with your package, create a new directory for them within your project and select Add Library... instead.
    It is not necessary to put external JARs in the assets folder.

   通过上面的方法能够生成jar,使用的时候compile也能成功,但是运行的时候会出错,原因是需要用到的jar没有打包到apk里面。要把jar打包到apk里面还需要下面的步骤。

1、在Android项目根目录下新建一个libs文件夹;
2、把你需要的导入的第三方Jar包复制进这个目录;
3、在libs目录上点右键,选Bulid path –> Use as source folder。
