Ubuntu 64 bit 编译 Android[Linux安全]

　　The Android build requires a 32-bit build environment as well as some other tools:

　　Required Packages:

　　Git, JDK, flex, and the other packages as listed above in the i386 instructions:

　　JDK 5.0, update 12 or higher.Java 6 is not supported, because of incompatibilities with @Override.

　　Pieces from the 32-bit cross-building environment

　　$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev

　　Set the system to use the right version of java by default:

　　$ sudo update-java-alternatives -s java-1.5.0-sun

　　注意:32 bit Required Packages 为

　　git-core gnupg sun-java5-jdk flex bison gperf build-essential zip curl zlib1g-dev libsdl-dev libesd0-dev libwxgtk2.6-dev libncurses5-dev

　　而Ubuntu 64 bit 下的 Required Packages 为 git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev

　　32bit与64bit下的依靠包 差别之处在于橙色与红色部份

　　大概招致错误情形:

　　bin/bash: 第 0 行: cd: sdk/layoutopt/app/src/resources: 没有那个文件或目录
