Error while Launching activity

修改代码之后，点击运行，AndroidStudio没有进行重新编译，而是提示no changes to deploy，然后启动修改前的那个APP，代码修改完全没用。这个问题初步判断是由于AndroidStudio的Instant run功能出错导致的。目前只能在settings->Build,Execution,Deployment->Instant Run中将Enable Instant Run to hot swap code/resource changes on deploy选项的勾点掉。这是默认启用的。点掉之后就正常了，每次点击运行都会重新安装APP。
