[Android] Android 4.2 source code download (Ubuntu 12.10) cutting-edge

Recently, I have been studying NFC. Different APIs in different versions are used differently. If you want to see the source code implementation, You have to download the android source code again ~~~

 

Complete steps: installing some soft

1 install curl: sudo apt-Get install curl

2 install Git-core: sudo apt-Get install Git-core

 

Installing Repo

1Create a ~ in the user directory ~ /Bin directory, and add it to the environment variable (to download and install the GIT software in this directory, the software may not be found in other directories, so add it to the environment variable)

$ Mkdir ~ /Bin

$ Path = ~ /Bin: $ path

2Download the repo script and change the permission to Executable

$ Curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo> ~ /Bin/Repo

$ Chmod A + x ~ /Bin/Repo

Initializing a repo Client

1Create a directory to save the android source code, change it to the maximum permission, and enter the Directory

$ Mkdir/opt/android4.2

$ Sudo chmod-r 777/opt/android4.2

$ CD/opt/android4.2

2Initialize the repo and select the branch (version) to be downloaded)

$ Repo init-u https://android.googlesource.com/platform/manifest

$ Repo init-u https://android.googlesource.com/platform/manifest-B android-4.2_r1

Note 1: In this process, enter your name, email address, and other information.

Note 2: Query Android version information, refer to the https://android.googlesource.com/platform/manifest/+refs

 

Getting the files

$ Repo sync

 

Problem

CodeThe following errors are frequently prompted during the download process:

Error: Failed connect to android.googlesource.com: 443; connection refused while accessinghttps: // android.googlesource.com/a/platform/frameworks/base/info/refs

Fatal: http request failed

Error: cannot fetch platform/tools/motodev

Error: cannot fetch platform/frameworks/base

Error: cannot fetch platform/prebuilts/SDK

Error: Exited sync due to fetch errors

Solution:Edit the/etc/hosts file

$ Vim/etc/hosts

Add and save the following content (save in advance ):

74.125.31.82 www.googlesource.com

74.125.31.82 android.googlesource.com

203.208.46.172 cache.pack.google.com

59.24.3.173cache.pack.google.com

Then enter again

$ Repo sync
