android2.3 源码编译及导入模拟器
编译环境Ubuntu11.04 32位机器
下载完代码后，进行make， $cd ~/myAndroidsource $make 却出现了如下错误： build/core/main.mk:73: You are attempting to build on a 32-bit system. build/core/main.mk:74: Only 64-bit build environments are supported beyond froyo/2.2. 这是因为froyo/2.2默认只支持64-bit，看到有些网友还要去下载64-比他的操作系统，很是麻烦，于是通过不断搜索资料终于解决，
解决办法：
需要进行如下修改即可，
将
./external/clearsilver/cgi/Android.mk
./external/clearsilver/java-jni/Android.mk
./external/clearsilver/util/Android.mk
./external/clearsilver/cs/Android.mk
四个文件中的
LOCAL_CFLAGS += -m64
LOCAL_LDFLAGS += -m64
注释掉，或者将“64”换成“32”
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32
然后，将
./build/core/main.mk 中的
ifneq (64,$(findstring 64,$(build_arch)))
改为：
ifneq (i686,$(findstring i686,$(build_arch)))
1、进入到源码文件夹下 执行make命令开始编译
target thumb C: libwnndict <= packages/inputmethods/OpenWnn/libs/libwnnDictionary/engine/ndldic.c
target thumb C: libwnndict <= packages/inputmethods/OpenWnn/libs/libwnnDictionary/engine/ndrdic.c

Target ram disk: out/target/product/generic/ramdisk.img
Target userdata fs image: out/target/product/generic/userdata.img
Installed file list: out/target/product/generic/installed-files.txt
出现上面的提示信息说明编译已经完成，同时会发现在代码目录下多了一个out目录。
2、安装Android模拟器android-sdk-linux_x86
到google网站下载http://developer.android.com/sdk/index.html页面下载android-sdk_r04-linux_x86.tgz到/usr/local/并解压，加压后文件夹/usr/local/android-sdk-linux_86/tools/中包含有 emulator模拟器。
编辑/etc/profile添加模拟器执行环境变量
PATH = ”$PATH: / home / lvs / out / host / linux - x86 / bin”
ANDROID_PRODUCT_OUT =/ home / lvs / out / target / product / generic
export ANDROID_PRODUCT_OUT
