错误弹窗如图:

Installation failed with message...It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

Installation failed with message Failed to finalize session: INSTALL_FAILED_TEST_ONLY:installPackageLI.

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?

 

解决方法:

1、打开菜单File——Settings——Build,Execution,Deployment——Instant Run

2、不选中Enable Instant Run to hot swap code/resource changes on deploy(default enabled)

3、依次点击Apply——OK,重新运行程序,大功告成。 

Installation failed with message...It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

 

 

备注:笔者所用手机是华为荣耀7,百度发现有人用小米手机也遇到这样的问题,解决方式是通用的,如果其他手机也遇到这种问题,欢迎大家留言讨论。

 

如果你没有成功,接下来使用第二招。

1、打开Edit Configurations...

2、在Install Flags中写上“-t”

3、依次点击Apply——OK,重新运行,大功告成。

Installation failed with message...It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

到此问题已经解决。

如果你还没有解决,我也没有第三招了,如果你有了第三招,请记得留言告诉我一下~~~
