hi粉丝朋友们：
在android高版本编译时候经常会遇到framework一个相关任务编译时候经常把内存吃满：
//frameworks/base:system-api-stubs-docs-non-updatable metalava merged
导致oom即内存不足这种，那么怎么解决呢在不加内存条情况下
<>1、官方建议方法减少编译线程
22:42:20 ************************************************************
22:42:20 You are building on a machine with 15.5GB of RAM
22:42:20
22:42:20 The minimum required amount of free memory is around 16GB,
22:42:20 and even with that, some configurations may not work.
22:42:20
22:42:20 If you run into segfaults or other errors, try reducing your
22:42:20 -j value.
22:42:20 ************************************************************
所以这个时候你就把：make 变成 make -j 1 (-j
1代表只用一个线程编译，太慢了，所以一般是耗内存打的报错那个任务编译完成后，你再停止重新make 默认线程数)
<>2、增加swap内存，通过增加虚拟内存的方法扩大内存
swap是啥大家自己百度哈，大概就是用电脑硬盘当内存用
2.1、创建文件
dd if=/dev/zero of=/var/swap bs=1M count=10240
of：文件的保存路径
bs=1M count=10240：文件的大小为1MB*10240 = 10GB
创建的时间可能会久一点，大概一两分钟。
2.2、将文件格式化为swap文件
mkswap /var/swap
2.3、挂载swap文件
swapon /var/swap
这样，虚拟内存就扩充好了，可以通过命令查看服务器的内存情况：
free -m
系统重启，则需要重新挂载swap文件
想要永久：
vim /etc/fstab
最末尾加入如下：
/var/swap none swap sw 0 0
