APK通过USB 安装失败

按运行后，安装时：

 

Installation failed with message Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

Log信息为：Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user

 

解决步骤：

　　1：clean project
