1在ubuntu中编译android6.0时需要openjdk7,但是openjdk-7-jdk和openjdk-7-jre需要同时安装。
, $ sudo apt-get安装openjdk-7-jre
, $ sudo apt-get安装openjdk-7-jdk
<>强PS: openjdk-7-jre包只包含Java运行时环境(Java运行时环境)。如果是要开发Java应用程
<强>序,则需要安装openjdk-7-jdk包。

2在ubuntu中更新jdk链接
安装Oracle jdk 8> tar -xvzf jdk-8-linux-x64.tar。广州
jvm创建文件夹在特性,如果jvm文件夹不存在
sudo mkdir /usr/lib/jvm 提取jdk 8文件夹移动到这个位置:
sudo mv jdk1.8.0 /usr/lib/jvm/jdk1.8.0 安装新的java源系统:
sudo update-alternatives ——install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0/bin/javac 1
sudo update-alternatives ——install /usr/bin/java java /usr/lib/jvm/jdk1.8.0/bin/java 1
sudo update-alternatives ——install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.8.0/bin/javaws 1
选择缺省java:
sudo update-alternatives ——config javac
sudo update-alternatives ——config java
sudo update-alternatives ——config javaw
Java版本测试:

3 android N编译
1)编译错误
java heap spaceTry increasing heap size with java option “-Xmx 解决方案:在文件/主机/linux-x86/bin/jack-admin添加值
export JACK_SERVER_VM_ARGUMENTS=?Dfile.encoding=UTF-8 - xx: + TieredCompilation “
然后重启/主机/linux-x86/bin/jack-admin kill-server/主机/linux-x86/bin/jack-admin 启动服务器
5,编译andorid orea内存不够:
解决方案:
从而problem is that virtual machine which runs jack 并't have enough 内存。
你还要try 用edit jvm 命令:JACK_VM_COMMAND=$ {JACK_VM_COMMAND:=" java -Xmx4096m "}
或是用decrease number of parallel jack compilationsSERVER_NB_COMPILE=2
拷贝文件。
你还要read jack documentation for details.EDIT:
Changing .jack file 并't work for 我。
After digging a little deeper 小姐:found that jack server is started with /主机/linux-x86/bin/jack-admin script 以及它's parameters 还要be
passed with JACK_SERVER_VM_ARGUMENTS environment variable.So my solution was
用set it 以及restart jack server before building aosp
: ,,,6在android8orea, cts中添加第三方jar包:LOCAL_STATIC_JAVA_LIBRARIES:=poi(在)
cts时,出现错误:,
javalib。jar、重命名classes.jar。再次编译,就可以了。
