Installation failed with message Invalid File: C:\Users\yqekzb\Desktop\BiaoQingBao\app\build\intermediates\split-apk\debug\slices\slice_9.apk.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?

解决方案1:
clean 再编译
解决方案2:
Clean Project之后再试，如果还不行就在模拟器上面卸载该app，然后再试，还不行就重启AS和模拟器，再试，还不行，就重启电脑。
就这么简单
