[2013-12-03 17:04:03 - ViewPaperTest] Re-installation failed due to different application signatures.
[2013-12-03 17:04:03 - ViewPaperTest] You must perform a full uninstall of the application. WARNING: This will remove the application data!
[2013-12-03 17:04:03 - ViewPaperTest] Please execute 'adb uninstall com.example.viewpapertest' in a shell.

解决办法
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D:\android\android-sdk-windows\platform-tools 下
D:\android\android-sdk-windows\platform-tools> adb uninstall
com.example.viewpapertest'
重新运行就可以了
