問題：
Installation failed with message Failed to commit install session 563460486 with command cmd package install-commit 563460486. Error: 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.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
解決辦法：
1.在編輯器依次點擊File->Setting->Build->Instant Run（圖片非本人截圖）
2.再次運行程序，還會出現 Session 'app': Install failed.Installation failed ，Rerun
在手機開發者選項界面中，最後一排有個“啓用MIUI優化” ，默認是開啓，把這個選項關掉，會提醒重啓，重啓後就好了
