Why do I get a emulator-5554 disconnected message




我在Eclipse中运行我的应用程序，并在控制台中找到以下结果

[2011-09-27 12:47:58 - AndroidBlackjack] Android Launch!
[2011-09-27 12:47:58 - AndroidBlackjack] adb is running normally.

[2011-09-27 12:51:12 - AndroidBlackjack] emulator-5554 disconnected! Cancelling 'com.android.blackjack.Setup activity launch'!

请帮我
我不明白。

解决方案（Eclipse IDE）

Select & Right Click on Android Project
Run Configurations
Go to tab Target
Enable option Wipe User Data on Emulator launch parameters
Run Application

如果使用其他IDE，则可以使用-wipe-data标志重新启动仿真器，以删除仿真器在先前运行中创建的所有临时文件。
