推荐答案

在＆LT;活性GT; 要启动通过应用程序列表上的图标的活性元素必须包含的的意图过滤器以下几部分组成两个的：

The <activity> element of the activity you want to launch through the icon on the app list must contain both of the following parts of the intent-filter:

<intent-filter>
    <category android:name="android.intent.category.LAUNCHER" />

    <action android:name="android.intent.action.MAIN" />
</intent-filter>

您当前的清单与目录 LAUNCHER 和行动主的活动，但在不同的活动。一个在应用程序列表中的图标必须有他们两个。

Your current manifest has an activity with category LAUNCHER and action MAIN, but in different activities. The one with the icon in the app list must have them both.
