全志A40I安卓系统编译

简介

最近有项目需求需要使用安卓系统安装APP来实现项目需求，所以就选了全志的A40I平台，符合工业控制的要求，下面是安卓系统的编译过程还有遇到的一些问题，特此记录一下

编译环境我使用的是飞凌嵌入式提供的Docker环境，因此不需要安装过多编译和依赖软件，具体的环境搭建这里先不做介绍，后边我再具体讲一下如何配置Docker环境以及基于Ubuntu搭建编译环境

android7.0源码编译问题总结

我使用的是飞凌使用Docker搭建的编译环境，在编译过程中出现一些问题

USER问题(由于运行的 docker 容易没有配置 USER 环境变量)

JACK VMCOMMAND =" java - Dfile . encoding = UTF -8-Xms2560m- XX :+ TieredCompilation - jar out / host / linux -x86/framework/ jack - launcher . jar " JACK _ JAR =" out / host / linux -x86/framework/ jack . ja " outhost / linux -x86/bin/ jack - admin start - server out / host / linux -x86/bin/ jack - admin : line 27: USER : unbound variable 

这是由于 docker 没有设置 USER 环境变量导致,手动添加后继续编译即可

export USER=$(whoami)

也可以在 docker 构建文件 Dockerfile 中加上如下语句:

ENV USER root /或者自己需要的名字

编译android7.0出现的错误ninja: build stopped: subcommand failed.

ninja: build stopped: subcommand failed.

解决方法：

$ vi prebuilts/sdk/tools/jack-admin

1.找到如下语句：

JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR 	$JACK_SERVER_VM_ARGUMENTS -cp $LAUNCHER_JAR $LAUNCHER_NAME"

2.将上述语句修改为：

JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS -Xmx4096m -cp $LAUNCHER_JAR $LAUNCHER_NAME"

主要是添加了-Xmx4096m参数，接下来在源码目录下执行如下命令重启jack-admin服务：

$ ./prebuilts/sdk/tools/jack-admin stop-server 
$ ./prebuilts/sdk/tools/jack-admin start-server
