套件构建过程中出现异常如何解决?
我已按照以下步骤来测试我的应用程序。
- 我已经创建了 Android 项目。
- 我已经为我的示例应用程序和测试应用程序(需要测试)创建了调试签名
- 将sampleapp_debug.apk放在bin文件夹中(我的工作区在那里)
- 在模拟器中安装了testapp_debug.apk。
- 现在我正在将项目作为 Android JunitTest 运行。
我收到以下错误..如何解决这个问题..

I have followed the below steps to test my app.
- I have created Android Project.
- I have created the debug signature for my sample app and test app(which need to be tested)
- Place the sampleapp_debug.apk in the bin folder (where my workspace is there)
- Installed the testapp_debug.apk in the emulator.
- Now i am running the project as a Android JunitTest.
I am getting the below error.. How to resolve this..

我以前遇到过类似的问题。我通过在 Testcode 中使用默认构造函数而不是参数化构造函数解决了同样的问题。以下教程对我很有用
查看本教程
I faced similar type of problem before. I resolved the same by using default constructor in Testcode rather than parametrized constructor. The following tutorial was useful for me
See this tutorial
我遇到了同样的错误,这个解决方案对我有用:
正如 W.Elsinga 在他的评论中提到的那样 链接
I encounter the same error and this solution worked for me:
as what W.Elsinga mention on his comment found here Link
您引用的代码太旧了。
只需添加默认构造函数即可。
Your referenced code was way old.
Just add default constructor.
我认为问题出在方法:
android.test.suitebuilder.TestMethod.getAnnotation()
。尝试在活动的构造函数中调用方法
setName()
。请参阅:使用 ActivityUnitTestCase 时出现 RuntimeException,但在 ActivityInstrumentationTestCase2 时出现 RuntimeException
异常也是由
android.test.suitebuilder.TestMethod.getAnnotation()
引起的。I think the problem at method:
android.test.suitebuilder.TestMethod.getAnnotation()
.Try to call the method
setName()
at constructor of the activity.See: RuntimeException while using ActivityUnitTestCase, but not while ActivityInstrumentationTestCase2
The exception is caused by
android.test.suitebuilder.TestMethod.getAnnotation()
, too.
