AndroidHttp Exception NoClassDefFoundError

Question

Well am using eclipse to make an android app which accesses google calendar API am getting a NoClassDefFoundError Exception whenever i tried to execute this method

private void setupCalendarConnection(final String accessToken) throws IOException {

    HttpTransport transport = AndroidHttp.newCompatibleTransport();// Here where the exception 
    GoogleCredential googleCredential = new GoogleCredential().setAccessToken(accessToken);
    JacksonFactory jacksonFactory = new JacksonFactory();

also i tried to replace it with

HttpTransport transport = new NetHttpTransport () ;

and i got the same error

05-07 20:08:04.513: E/AndroidRuntime(781): java.lang.NoClassDefFoundError: com.google.api.client.extensions.android2.AndroidHttp

From my knowledge in Java.. This exception means that the class am trying to access is not defined by classLoader ALTHOUGH i checked the dependencies and JAR files included and it is included and imported

So any clue about how can i solve this problem Thank you in advance..

Go to your build path in Eclipse via Project >> Properties , then Java Build Path . Under the tab Order and Export , tick the library you are importing.

当我前往Netbeans而不是Eclipse并将我的Jars手动导入libs文件夹中时，问题就解决了……自动添加到Project中，它像火马一样运行。
