来自 release notes for Android 3.1:

Starting from Android 3.1, the system's package manager keeps track of applications that are in a stopped state and provides a means of controlling their launch from background processes and other applications.

Applications are in a stopped state when they are first installed but are not yet launched and when they are manually stopped by the user (in Manage Applications).

您应该包含一个可以由用户启动的 Activity,否则您的应用将永远不会退出此停止状态。
