我是在導入已經存在的項目時出現的錯誤Re-installation failed due to different application signatures
調試信息如下：
[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!
這時先運行android模擬機，進入命令行,當然你要定位adb.exe的目錄,我是放在E:\android\android-sdk-windows\platform-tools 下
E:\android\android-sdk-windows\platform-tools> adb uninstall com.example.android.apis.
重新運行就可以瞭
