Android 源码下载、编译以及编译自己的apk

一、Android源码下载与编译

基于VMware 7.0 、ubuntu10.0464位

1、Git工具。

若无则安装 ~$ sudo apt-get installgit-core gnupg

2、Java sdk 。

~$sudo add-apt-repository ppa:ferramroberto/java

~$sudo apt-get update

~$sudo apt-get install sun-java6-jre sun-java6-plugin

~$sudo apt-get install sun-java6-jdk

另：接受安装条件时，tab键切换焦点。

3、安装其他需要的命令

~$sudo apt-get install flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl

4、调试工具

~$sudo apt-get install valgrind

5、安装repo工具

~$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
~$ chmod a+x ~/bin/repo

修改文件.bashrc

~$ vi .bashrc

在最后一行加入export PATH=$PATH:~/bin

保存，执行~$./.bashrc

6、创建下载目录android并初始化repo

~$ mkdir android

~$ cd android/

初始化

~/android$ repo init -u https://android.googlesource.com/platform/manifest -bandroid-2.3.1_r1

下载（慢慢等吧）

~/android$ repo sync

7、编译（这里也慢慢等）

~/android$ make

注意：

出现错误，首先，全部赋予可执行权限

错误：find: `frameworks/base/frameworks/base/docs/html': No such file or directory
find: `out/target/common/docs/gen': No such file or directory

此错误忽略，不影响编译

错误：/usr/include/gnu/stubs.h:7: fatal error: gnu/stubs-32.h: No such file or directory
解决方法：~/android$ sudo apt-get install libc6-dev-i386

错误：external/clearsilver/cgi/cgi.c:22: fatal error: zlib.h: No such file or directory

解决方法：~/android$sudo apt-get install zlib1g-dev

错误：/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/acp_intermediates/acp] Error 1

解决方法：~/android$sudo ln -s /usr/lib32/libstdc++.so.6 /usr/lib32/libstdc++.so

中间或许还有其他各种错误，遇到了自己百度去。

编译成功会有如下输出

Target system fs image:

out/target/product/generic/obj/PACKAGING/systemimage_intermediates/system.img

Install system fs image: out/target/product/generic/system.img

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

8、运行

启动模拟器，运行$ emulator

错误：No command 'emulator' found, did you mean:
Command 'qemulator' from package 'qemulator' (universe)
emulator: command not found

解决方法：编辑/etc/environment

加入环境变量

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:usr/lib/jvm/java-6-sun-1.6.0.26/bin:/home/nanlus2/android/out/host/linux-x86/bin"
CLASSPATH="/usr/lib/jvm/java-6-sun-1.6.0.26/lib"
JAVA_HOME="usr/lib/jvm/java-6-sun-1.6.0.26"
ANDROID_PRODUCT_OUT="/home/nanlus2/android/out/target/product/generic"

注：/home/nanlus2/android为源码目录

保存，重启。运行$ emulator

错误：SDL init failure, reason is: No available video device

解决方法：$apt-get install ia32-libs lib32stdc++6

再次运行$ emulator

成功

二、编译自己的apk

1、编写完成工程。

2、编写Android.mk文件，放入工程目录下

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := helloworld
LOCAL_CERTIFICATE := platform
include $(BUILD_PACKAGE)
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

3、编译

拷贝工程至packages/apps/下

~$ cp -ri helloworld ~/android/packages/apps/helloworld

进入目录 ~/...../helloworld$ mm

编译成功：out/target/product/product_name/system/app/helloworld.apk

4、运行

安装在机子上运行之。adb install xxx/helloworld.apk

在这里也可以一起打包，

$make snod

然后，再运行，启动模拟器即可。
