[Original] Compile the Android source process encountered problems

The process of compiling Android source code refer to the Android website:

1, download the Android source code step: https://source.android.com/source/downloading.html

2, compile the Android source code step: https://source.android.com/source/building-running.html

Here are some of the problems I have encountered:

1. JDK-related error when Compile Android Source:
