Error:Re-installation failed due to different application signatures. You must perform a full uninstall of the application. WARNING: This will remove the application data! Please execute 'adb uninstall com.gesoft.qualitycontrol' in a shell.

解决方案:

确保你有一个调试工具（模拟器或者手机只能选一个，有多个时先关闭） 运行-cmd 定位与Android SDK中platform-tools目录，也就是在adb.exe文件的父目录下 定位完成之后，在命令行中输入： 报错内容第三行中引号内的内容'adb uninstall com.gesoft.qualitycontrol' 执行后提示成功，重启模拟器，运行程序即可解决问题。
