今天在Ubuntu 14.02 (64位)下安装了Android开发环境,其中遇到adb无法使用的情况,以为是没配置环境变量的问题,就添加一下:

1
sudo vim /etc/profile
1
2
export PATH="$PATH:/home/username/sdk/tools"
export PATH="$PATH:/home/username/sdk/paltform-tools"

但是系统注销后运行,还是会报错:没有该文件或文件夹。

经查阅发现Linux下SDK的adb命令是32位的,所以要在64位系统上要安装兼容包:

Ubuntu 13.10及以上的版本:

1
2
3
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386

以下的版本:

1
apt-get install ia32-libs

执行过后可发现adb可正常运行。

在国内下载Android可是不太容易,不过从Google断断续续地下载了几天源码后发现清华大学有个TUNA镜像源可以下载Android源码,甚是方便。

参考网站:

http://source.android.com/index.html

https://aosp.tuna.tsinghua.edu.cn/

一.环境准备:

现在Android源码的下载和编译在Linux和Mac OS上都可以了,但Mac OS上设置略微复杂点,所以我选择了Ubuntu 14.04 64位的虚拟机。(硬盘建议50G以上,编译的时候给虚拟机加大CPU和内存。)

编译Gingerbread (2.3.x) 及其以上的源码需要64位的系统,以下的可以在32位系统上编译。

1.Java下载和配置

Java 7:适用最新版的源码:

1
2
$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk

如果系统上有多个Java版本,可以设置默认的:

1
2
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac

Java 6: 适用于Gingerbread(2.3)~ KitKat(4.4)

Java 5:适用于 Cupcake(1.5)~ Froyo(2.2)

如果Java安装失败可到Java官网下载后自行安装,略去不表。

2.其它依赖包:

1
$ sudo apt-get install bison g++-multilib git gperf libxml2-utils make zlib1g-dev:i386 zip

但在编译过程中发现还需要两个包,所以也提前安装好吧:

1
$ sudo apt-get install flex libswitch-perl

如果是Ubuntu 12.04:

1
2
3
4
5
6
$ sudo apt-get install 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 \
libgl1-mesa-dev g++-multilib mingw32 tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

如果是Ubuntu 10.04 – 11.10:

1
2
3
4
5
$ sudo apt-get install git gnupg flex bison gperf build-essential \
zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs \
x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev \
libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown \
libxml2-utils xsltproc

11.10:

1
$ sudo apt-get install libx11-dev:i386

10.04:

1
$ sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so

二、下载源码

1.下载repo:

repo是Google基于Git推出的一款版本管理工具,用python写的。

先配置目录:

1
2
$ mkdir ~/bin
$ PATH=~/bin:$PATH

下载repo并赋予其可执行权限:

1
2
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

当然由于众所周知的原因,我们往往无法把repo下到本地。这里提供一个我下载并修改好的下载链接:http://jiezhiblog.com/wp-content/uploads/2015/04/repo1.txt

(wp的限制,只能把repo重命名为repo.txt,下载后改回repo即可)

下载放到~/bin目录下,并修改权限即可:

1
chmod a+x repo

2.初始化repo

进入放置源码的目录,如:

1
2
$ mkdir ~/android/android 4.3_r1
$ cd ~/android/android 4.3_r1

关键的来了,如果想体验好点,建议国内的从清华大学的镜像源下载:

1
$ repo init -u git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest

或者指定要下载的分支:

1
$ repo init -u git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest -b android-4.3_r1

完成后即可和服务器同步了:

1
$ repo sync

该服务器限制了每个IP并发数,也就是你可以使用:

1
$ repo sync -j4

设置并发数为4.,给别人留有余地。

现在应该在从服务器下载源码了,但是如果中途有中断了,继续执行repo sync即可。

如何让repo自动在断开后自动下载:

新建autorepo.sh:

1
2
3
4
5
6
#!/bin/sh
repo sync
while [ $? -ne 0 ]
do
repo sync
done

然后执行即可:

1
$ sh autorepo.sh

如果你之前已经下载了部分AOSP的代码的话,切换到TUNA服务器也很方便,如官网所示:

如果你之前已经通过某种途径获得了 AOSP 的源码(或者你只是 init 这一步完成后), 你希望以后通过 TUNA 同步 AOSP 部分的代码,只需要将 .repo/manifest.xml 把其中的 aosp 这个 remote 的 fetch 从 https://android.googlesource.com 改为 git://aosp.tuna.tsinghua.edu.cn/android/

diff<manifest> <remote name="aosp"- fetch="https://android.googlesource.com"+ fetch="git://aosp.tuna.tsinghua.edu.cn/android/" review="android-review.googlesource.com" /> <remote name="github"

这个方法也可以用来在同步 Cyanogenmod 代码的时候从 TUNA 同步部分代码

三、编译:

当源码下载后,可以看到目录里多出很多源码文件夹:

drwxrwxr-x 9 aosp aosp 4.0K Apr 7 11:34 system

如果你准备在模拟器里运行,则按照如下步骤编译即可,如果你想刷到手机上则还有一些任务要做(见第四步)。

0.其中由于配置问题,我的代码是放在服务器上编译的:

由于.repo这个隐藏文件夹里的文件占用空间很大,所以在压缩的时候将其排除:

1
$ tar -zcvf android4.3_r1.tar.gz android4.3_r1/ --exclude .repo

然后利用scp命令将压缩好的文件上传到服务器:

1
$ scp android4.3_r1.tar.gz username@host:/home/android/

其中username和host是你用户名和服务器地址。

解压:

1
$ tar -zxvf android4.3_r1.tar.gz /

1.初始化:

1
$ source build/envsetup.sh

2.使用lunch命令选择编译目标,如:

1
$ lunch aosp_arm-eng

或者直接lunch,会让你选择编译目标的。

其中参数说明:

BUILD NAME DEVICE NOTES
aosp_arm ARM emulator 包括所有语言、APP和输入法的配置
aosp_maguro maguro 运行在Galaxy Nexus GSM/HSPA+ (“maguro”)上
aosp_panda panda 运行在 PandaBoard (“panda”)上
BUILDTYPE USE
user limited access; suited for production(有权限限制,适合产品级)
userdebug preferred for debugging(适合调试)
eng development configuration with additional debugging tools(有额外的调试工具)

4.3.编译

1
$ make -j4

-jN表示用N个线程来编译,如果你是配置是2CPU,每个CPU有4核,每核可跑俩线程,那么你可以make -j16乃至-j32,这样速度将大大加快。.

4.成功

在android4.3_r1/out/target/product/generic目录下可以看到如下文件:

-rw------- 1 aosp aosp 99K Apr 7 15:19 userdata.img

四、刷机

1.模拟器的话,其实直接运行emulator即可运行:

由于不涉及内核,我的做法是把ramdisk.img、system.img和userdata.img复制到sdk/system-images/android-18/default/armeabi-v7a/目录下替换掉原来的文件。(可以把原来的先备份)
然后新建对应的API虚拟机,运行即可。

2.真机

真机我是用Google三太子Galaxy Nexus [maguro] (GSM/HSPA+)做的实验,毕竟亲儿子,驱动方面都很好配置。

a.在第三步编译之前,先把驱动配置好:

$ ./extract-broadcom-maguro.sh # (view the license and then type "I ACCEPT")

$ wget https://dl.google.com/dl/android/aosp/imgtec-maguro-jwr66y-b0a4a1ef.tgz
$ tar -zxvf imgtec-maguro-jwr66y-b0a4a1ef.tgz
$ ./extract-imgtec-maguro.sh # (view the license and then type "I ACCEPT")
...
$ wget https://dl.google.com/dl/android/aosp/invensense-maguro-jwr66y-e0d2e531.tgz
$ tar -zxvf invensense-maguro-jwr66y-e0d2e531.tgz
$ ./extract-invensense-maguro.sh # (view the license and then type "I ACCEPT")
...
$ wget https://dl.google.com/dl/android/aosp/nxp-maguro-jwr66y-d8ac2804.tgz
$ tar -zxvf nxp-maguro-jwr66y-d8ac2804.tgz
$ ./extract-nxp-maguro.sh # (view the license and then type "I ACCEPT")
...
$ wget https://dl.google.com/dl/android/aosp/samsung-maguro-jwr66y-fb8f93b6.tgz

$ ./extract-samsung-maguro.sh # (view the license and then type "I ACCEPT")
...
$ wget https://dl.google.com/dl/android/aosp/widevine-maguro-jwr66y-c49927ce.tgz
$ tar -zxvf widevine-maguro-jwr66y-c49927ce.tgz
$ ./extract-widevine-maguro.sh # (view the license and then type "I ACCEPT")

然后按照第三步编译即可。

b.连接手机,打开USB调试,进入bootloader模式:

1
$ adb reboot bootloader

如果bootloader被锁住的话,先解锁:

1
$ fastboot oem unlock

然后进入system.img等文件的目录:

1
2
3
4
5
$ fastboot flash boot boot.img
$ fastboot flash system system.img
$ fastboot flash userdata userdata.img

然后重启即可。

repo的下载与安装

发布在 Android

这两天在张罗着下载Android源码,结果在安装repo的时候老是提示找不到服务器。

1
curl https://storage.googleapis.com/git-repo-downloads/repo &gt; ~/bin/repo
