配置jdk以及ndk

ubuntu下JDK配置本质上和win是一样的：

1、去官网下载JDK、NDK

2、解压后得到名字为jdk = 1.8.0_131的文件夹，ndk = android-ndk-r14b。

3、配置jdk和ndk环境变量：

在启动终端并输入

 
   gedit/etc/profile

在末尾添加一下配置，保存并退出

 
  #setjdkenvironment
 exportJAVA_HOME=/home/jeck/jdk/jdk1.8.0_131
exportCLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH
exportPATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

export ANDROID_NDK=  /home/jeck/ndk/android-ndk-r14b
 PATH=$ANDROID_NDK:$PATH

终端输入一下命令使配置生效

source/etc/profile

4、查看配置是否成功。在终端输入

java-version

如果显示版本是1.7.0.21则配置成功，如下显示：

javaversion"1.8.0_131"Java(TM)SERuntimeEnvironment(build1.8.0_131-b11)
JavaHotSpot(TM)ServerVM(build23.21-b01,mixedmode) 
 
   ndk测试,在终端输入，如下显示配置成功:

 PARTICULAR PURPOSE.

   如果显示仍是openJDK，执行步骤5，再测试

5、配置默认JDK，ubuntu下默认JDK是openJDK。。终端输入

sudoupdate-alternatives--install/usr/lib/javajava/usr/lib/jvm/jdk1.7.0_17/bin/java300

sudoupdate-alternatives--install/usr/lib/javacjavac/usr/lib/jvm/jdk1.7.0_17/bin/javac300

执行下面命令，配置需要默认的JDK

sudoupdate-alternatives--configjava

会列出jdk版本，其中被“*”标注的为默认JDK。如果要维持当前默认JDK，直接按回车键即可；否则输入相应JDK的编号将其设置为默认版本。
