Android 调式：Re-installation failed due to different application signatures.

如果Android程序已经在模拟器中运行，再次在eclipse中运行统一个程序，就会出现：

[2012-02-17 14:20:54 - AdroidTest1]Re-installation failed due to different application signatures.
[2012-02-17 14:20:54 - AdroidTest1]You must perform a full uninstall of the application. WARNING: This will remove the application data!
[2012-02-17 14:20:54 - AdroidTest1]Please execute 'adb uninstall com.nertica' in a shell.
[2012-02-17 14:20:54 - AdroidTest1]Launch canceled!

 

进入命令行,当然你要定位adb.exe的目录,我的是在D:\android_sdk_1.6\tools

cd D:\android_sdk_1.6\tools > adb uninstall com.example.android.apis
