“无法完成会话：INSTALL_FAILED_USER_RESTRICTED：无效的APK。”

Question

I am trying to install my app in mobile through android studio. It perfectly worked earlier but now it is returning this error

Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Invalid apk.

How to resolve this error?

Answer 1

I found my error and resolved it! In manifest file inside metadata element I had not mentioned valid value, by adding a value parameter the error got resolved. You will find detailed description here
