我今天一直在研究这个应用程序，我似乎无法弄清楚代码有什么问题。
当我检查时，没有语法错误。但是当我尝试运行并调试它时，它会说
"Source not found" on "ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2106`
它为我提供了选择其他路径的选项，但唯一可用的路径是默认设置。我编码错了吗？我该怎么做才能解决这个问题？
这是logcat：
12-20 22:12:29.722: I/System.out(1518): debugger has settled (1479)
12-20 22:12:30.172: W/Trace(1518): Unexpected value from nativeGetEnabledTags: 0
12-20 22:12:30.222: W/Trace(1518): Unexpected value from nativeGetEnabledTags: 0
下面是控制台错误：
[2012-12-20 17:19:45 - rockPaperScissorLizardSpock] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.rockpaperscissorlizardspock/.MainActivity }

听起来您需要将活动添加到AndroidManifest.xml中。它看起来像这样，位于清单的“应用程序”部分。您可以阅读此页面以获取更多信息：http://developer.android.com/guide/topics/manifest/manifest-intro.html
这是一个例子：
<activity
android:name=".rockpaperscissorlizardspock"
android:label="@string/app_name"
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
