Android 如果代码中没有错误，但应用程序没有在模拟器上运行，该怎么办？

我正在开发一个非常简单的android应用程序，包含活动和意图。代码中没有错误

控制台显示：

[2013-06-04 15:21:38 - Shoppapp] Android Launch!
[2013-06-04 15:21:38 - Shoppapp] adb is running normally.
[2013-06-04 15:21:38 - Shoppapp] Performing com.example.shoppapp.MainActivity activity 

发布：

[2013-06-04 15:21:48 - Shoppapp] Uploading Shoppapp.apk onto device 'emulator-5554'
[2013-06-04 15:21:53 - Shoppapp] Installing Shoppapp.apk...
[2013-06-04 15:22:49 - Shoppapp] Success!
[2013-06-04 15:22:50 - Shoppapp] Starting activity com.example.shoppapp.MainActivity on 

设备仿真器-5554

当我在emulator中打开应用程序时，会出现一个空白屏幕，然后它会随着消息关闭

不幸的是，您的应用程序已停止工作，并且应用程序已关闭

您是否将您的欢迎活动声明为清单文件

---

它显示ActivityNotFoundException:No Activity found to handle Intent

com.example.shoppap.WELCOME

异常清楚地自我解释：“原因：android.content.ActivityNotFoundException:No Activity to handle Intent{act=com.example.shoppap.WELCOME}”您没有在清单中声明活动
