android - 开发石头、布、剪刀、蜥蜴、斯波克问题

Question

我今天一直在开发这个应用程序，但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。但是当我尝试运行它并调试它时，它说

"Source not found" on "ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2106`

它让我可以选择另一条路径，但唯一可用的是默认设置。我编码错了吗？我该怎么做才能解决这个问题？

这是日志:

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

这是控制台错误:

听起来您需要将 Activity 添加到您的 AndroidManifest.xml。它看起来像这样，位于 list 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

举个例子:

    <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>
