我正在尝试使用 ActivityInstrumentationTestCase2 测试从 FragmentActivity（来自 android-support-v4.jar）派生的 Activity。android-support-v4.jar 位于我的主项目（测试项目）的 libs 文件夹中。为了使测试项目通过构建，我使用命令“ln ../mainProject/libs/android-support-v4.jar ./libs/android-support-v4”添加了一个从主项目到测试项目的链接。 jar”在我的测试项目根目录中。由http://dtmilano.blogspot.com/2009/12/android-testing-external-libraries.html?showComment=1348480869133推荐。按照博客中的指南，我可以使用 Eclipse 成功运行测试。但是，当我尝试使用命令“ant clean debug install test”运行测试时，总是会遇到以下异常：

[exec] android.test.suitebuilder.TestSuiteBuilder$FailedToCreateTests:
[exec] Error in testSuiteConstructionFailed:

这是测试代码的快照：

 public class QuestionListActivityTest extends ActivityInstrumentationTestCase2<QuestionListActivity>{
    private Solo solo;
    private FragmentActivity activity;

 public QuestionListActivityTest() {  
     super(QuestionListActivity.class); **// the exception happened here**
 }
...
}

我正在使用android sdk R15。测试是用模拟器运行的。有人知道如何解决吗？我真的需要用 ant 运行它，以便与 hudson 集成。提前致谢！
