解决错误：Re-installation failed due to different application signatures

在导入已经存在的项目时出现的错误Re-installation failed due to different application signatures

调试信息如下：

[2011-10-11 10:08:37 - ApiDemos] Re-installation failed due to different application signatures.

[2011-10-11 10:08:37 - ApiDemos] You must perform a full uninstall of the application. WARNING: This will remove the application data!

[2011-10-11 10:08:37 - ApiDemos] Please execute 'adb uninstall com.example.android.apis' in a shell.

[2011-10-11 10:08:37 - ApiDemos] Launch canceled!

这时先运行android模拟机，进入命令行,当然你要定位adb.exe的目录,我是放在E:androidandroid-sdk-windowsplatform-tools 下

E:androidandroid-sdk-windowsplatform-tools> adb uninstall ×××.×××.×××

（要卸载的程序所在的包名）

重新运行就可以了
