Summarize some of the problems encountered in the process

Version 1.repo. Unofficial repo tools may have secret key issues or download failures, please use the official version. The landlord with the old version of the repo for a long time, and later all deleted the new ...

2.VPN is unstable. This question does not explain many people all understand, LZ also did not buy more expensive line VPN. There is one solution, you can use Apple script to write a VPN automatic re-connect script, saved into the app. Please google for your own method. But occasionally there will be broken nets but the VPN is not broken, you can only manually re-connect.

3. The download and compilation time is too long. Download no statistics, estimates are not repo problem of that time, also more than 24 hours. Dalvik completely converted to art and added 5,000 APIs, compiling time significantly longer and compiling the total by 7 hours and 30 minutes.
