Android 6.0百度网盘下载
1、Android源码下载
参考了以下的下载失败重下载脚本：
[linuxidc@localhost android-src]$ cat myrepo.sh
#!/bin/sh
repo sync
while [ $? -ne 0 ]
do
echo "try repo sync again"
repo sync
done
[linuxidc@localhost android-src]$
下班前开始跑，第二天就有了。
2、编译第一次直接进入下载的源代码目录，运行make，过了3个多小时后，报错：

make之前还运行了下面的指令：
#source ./build/envsetup.sh
这个命令选择你的编译环境的硬件体系
#lunch
下面这个命令就开始编译了
#make
通过跟踪顶层makefile，找到有关jack的目录：prebuilts/sdk/tools，其中看到有个jack-admin，正是启动jack所在的shell。里面有个设置：
#
# Settings
#
JACK_HOME="${JACK_HOME:=$HOME/.jack-server}"
CLIENT_SETTING="${CLIENT_SETTING:=$HOME/.jack-settings}"
TMPDIR=${TMPDIR:=/tmp}
JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation}"
修改一下，增加-Xmx2048M:
#
# Settings
#
JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx:2048M}"
再次make，好像没起作用：

找到jack-admin中的start-server语句，直接在里面增加：
