3.解压代码+git apply导入patch
git apply xxx/xx/xx/x(patch所在的文件路径)
【精选】Git生成和导入Patch_git导入patch_ChampionDragon的博客-CSDN博客
4.编译
4.1 FAILED:setup-jack-server
解决：参考Ubuntu aosp 编译过程中Jack server SSL error 错误解决方法_ubuntu ssl error-CSDN博客
4.2 FAILED: out/target/common/obj/JAVA_LIBRARIES/core-all_intermediates/with-local/classes.dex

解决方案一（执行命令：ulimit -c unlimited）
命令解释
ulimint -a 用来显示当前的各种用户进程限制
Linux对于每个用户，系统限制其最大进程数，为提高性能，可以根据设备资源情况，
设置个Linux用户的最大进程数，一些需要设置为无限制：
数据段长度无限制
ulimit -d unlimited
最大内存大小无限制
ulimit -m unlimited
堆栈大小无限制
ulimit -s unlimited
core文件大小无限制
ulimit -c unlimited
