基于MTK平台的不同安卓版本软件编译的JDK版本GCC版本切换脚本

本人做MTK平台驱动工作快两年了，最近从之前的4.2和4.4要切换到L版本了，相应的编译环境需要修改。因为MTK的建议是4.4之前的版本用Oracle JDK1.6.045和GCC4.4的版本，而L要用OPEN JDK 1.7和GCC4.6，这就带来了同一机器上不能编译不同版本安卓工程的麻烦，本文的目的是通过切换环境的脚本实现同一机器可以编译不能版本安卓工程的目的。

首先安装配置好Ubuntu 12.04 x64，然后

1.Update apt information

$ sudo su -
[sudo] password for android:******
root@android-machine:~$ apt-get update

2.Install google recommended packages

$ apt-get install -y git gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
g++-multilib mingw32 tofrodos libgl1-mesa-dev \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

3.Install JDKandGCC

$ sudo apt-get -y install openjdk-7-jdk
$ update-java-alternatives -s java-1.7.0-openjdk-amd64

$ mkdir /opt/java
$ cd  /opt/java/
$ chmod a+x jdk-6u45-linux-x64.bin
$ ./jdk-6u45-linux-x64.bin

然后将以下代码复制到文件下运行

配置完后只有只需要在编译对应工程前source对应的脚本（Android 4.4之前的版本对应JDK1.6GCC4.4.sh，Android L对应JDK1.6GCC4.4.sh），底下附上脚本源码。
