你好 Android 测试错误

Question

嗨，当我运行你好 Android 测试 http://developer.android.com/resources/tutorials/testing/helloandroid_test.html

我收到以下错误

java.lang.RuntimeException: Unable to resolve activity for: Intent { act=android.intent.action.MAIN flg=0x10000000 cmp=com.example.helloandroid/com.ex.helloAndroid.HelloAndroid }
at android.app.Instrumentation.startActivitySync(Instrumentation.java:447)

at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:425)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1520)

我不明白为什么会出现这些错误并给我一些建议。在此先感谢

我猜你没有在 AndroidManifest.xml 文件中指定 Activity 名称

<activity android:name=".ClassName"
        android:label="@string/app_name">
    </activity>

类似于上面提到的代码。

希望对你有帮助！！
