java - 在 Android 模拟器中，Android 应用程序安装成功并显示在“设置”->“应用程序”下，但未显示在“应用程序”主屏幕上

Question

我安装了该应用程序，并收到以下消息

------------------------------
[2014-02-17 13:02:42 - Stealth1] Android Launch!
[2014-02-17 13:02:42 - Stealth1] adb is running normally.
[2014-02-17 13:02:42 - Stealth1] No Launcher activity found!
[2014-02-17 13:02:42 - Stealth1] The launch will only sync the application package on the device!
[2014-02-17 13:02:42 - Stealth1] Performing sync

我可以在“设置”-->“应用程序”下找到模拟器中安装的应用程序。但我应该如何运行该应用程序。我尝试从 eclipse 运行它。但我还是跑不了。当我从命令行运行时，我得到

您需要在 AndroidManifest.xml 中为您的主要 Activity 提供 LAUNCHER 类别。示例:

        <intent-filter android:label="@string/app_name">
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
