整体编译aosp源码，并导入到Android studio中，
// 切换到源码目录
cd ～/aosp
source build/envsetup.sh
mmm development/tools/idegen/
执行下面命令的时候出现报错：
sudo ./development/tools/idegen/idegen.sh
解决办法：安装openjdk-11-jdk,安装成功后，再次执行
sudo ./development/tools/idegen/idegen.sh
执行完上述命令，会在AOSP目录下生成两个文件android.ipr和android.iml,修改android.iml，尽量减少引用
