解决android调试是出现：Re-installation failed due to different application signatures

调试信息如下：
[2011-06-09 10:08:37 - ApiDemos] Re-installation failed due to different application signatures.
[2011-06-09 10:08:37 - ApiDemos] You must perform a full uninstall of the application. WARNING: This will remove the application data!
[2011-06-09 10:08:37 - ApiDemos] Please execute 'adb uninstall com.example.android.apis' in a shell.
[2011-06-09 10:08:37 - ApiDemos] Launch canceled!

在网上查是这样的：
这时先运行android模拟机，并在cmd内运行,当然你要定位adb.exe的目录,我是放在D:\android-sdk-windows\platform-tools 下

D:\android-sdk-windows\platform-tools> adb uninstall com.example.android.apis.

重新运行就可以了
