Android studio编译出现Failed to finalize session : INSTALL_FAILED_INVALID_APK

1、问题

我把项目里面的部分java文件导成jar文件，然后复制这个项目然后用Androi studio打开，导入jar编译出现这个错误

Installation failed with message Failed to finalize session : INSTALL_FAILED_INVALID_APK: Split lib_slice_7_apk was defined multiple times.
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?

2、解决办法

找到项目的目录,删除下面的3个文件

rm -rf .idea/

rm -rf .gradle/

rm -rf build

然后点击Build,然后点击Clean Project, ok ok
