【记录】编译测试Android nougat-x86

发表于2017-06-09    类别: 技术(66)    标签: 记录(27) Android(23)

一、获取源码

因为国内无法访问Google官网，在这个地方可以下载Android源码：清华大学开源软件镜像站AOSP

按其提示的方法，为避免直接repo sync太慢，先直接下载aosp-latest.tar，解压得到.repo目录，然后再运行：

$ repo init -u http://scm.osdn.net/gitroot/android-x86/manifest -b

此时不能repo sync，因为无法从google直接下载code，打开.repo/manifest.xml，作如下改动：

 <manifest>
 
   <remote  name="aosp"
-           fetch="https://android.googlesource.com/" />
+           fetch="https://aosp.tuna.tsinghua.edu.cn/" />
   <remote  name="x86"
            fetch="." />
   <default revision="refs/tags/android-7.1.2_r11"

再sync就可以了

$ repo sync --no-tags --no-clone-bundle -j4

二、编译

Build command

$ . build/envsetup.sh 
including device/generic/x86_64/vendorsetup.sh
including device/generic/x86/vendorsetup.sh
including sdk/bash_completion/adb.bash

$ lunch

You're building on Linux

Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_arm64-eng
     3. aosp_mips-eng
     4. aosp_mips64-eng
     5. aosp_x86-eng
     6. aosp_x86_64-eng
     7. android_x86_64-eng
     8. android_x86_64-userdebug
     9. android_x86_64-user
     10. android_x86-eng
     11. android_x86-userdebug
     12. android_x86-user

Which would you like? [aosp_arm-eng] 10

isohybrid not found.
Install syslinux 4.0 or higher if you want to build a usb bootable iso.


out/target/product/x86/android_x86.iso is built successfully.

Solution:

$ sudo apt-get install syslinux-utils


— Met Error: isolinux.bin missing or corrupt

Get this error message when test the boot image with USB stick.

Solution: You may need to use the following command

sudo dd if=linux.iso of=/dev/sdb

instead of

sudo dd if=linux.iso of=/dev/sdb1

三、测试

使用Virtual Box虚拟机测试，可以启动。

使用U盘作启动盘，也可以成功启动。在真实电脑上还可以插入USB摄像头，可以使用camera应用。
