This article mainly introduces "AOSP source code download and how to solve the problem". In daily operation, I believe many people have doubts about AOSP source code download and how to solve the problem. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "AOSP source code download and how to solve the problem". Next, please follow the editor to study!

I. explanation

Due to some reasons, using Google's resources to download Android source code is very slow, we can use the resources inside Tsinghua Source to download.

Second, source code download example

As the configuration download method is very clear in Tsinghua Source, here are only a few summaries:

1. Google Mirror is not available, use Tsinghua Source Mirror

Https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/

two。 Configure repo

Mkdir ~ / binPATH=~/bin:$PATHcurl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~ / bin/repochmod axix ~ / bin/repo

Note: repo is best added to the system's environment variables.

3. Repo update

During the operation of repo, you will try to access the official git source to update yourself. If you want to update yourself with tuna's mirror source, you can copy the following content to your ~ / .bashrc.

Export REPO_URL=' https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'

And restart the terminal emulator.

4. Download initialization package

Wget-c https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar

5. Decompress the resource package

Tar xf aosp-latest.tar

6. Update the specified version

For example, specify to download android-6.0.1_r62 and execute the following command:

Repo init-u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest-b android-6.0.1_r62repo sync

If you encounter an error such as "SyntaxError: invalid syntax", it is as follows:

File "/ home/jerry/workspace/aosp/.repo/repo/main.py", line 79 file=sys.stderr) ^ SyntaxError: invalid syntax

It should be caused by python syntax, and the solution is as follows:

Python3 ~ / bin/repo init-u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest-b android-6.0.1_r62python3 ~ / bin/repo sync

7. Shortcut script

Due to network and restrictions on network concurrency and other reasons, repo sync often fails to update. You can update it with script. Script example:

Repo sync-j4 while [$? = 1]; do echo "= sync failed, re-sync again =" sleep 3 repo sync-j4 done 3, pay attention

1. Encountered the problem of synchronization failure

For example, if the app synchronization of OMA-DM fails, we can modify .repo / manifests/default.xml in the AOSP directory to block the synchronization of this application, as shown below:

two。 Encountered a python syntax problem

Execute the repo command according to the actual situation according to the following syntax, and note that the repo should write the absolute path, otherwise an error will be reported.

Python3 ~ / bin/repo init-u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest-b android-6.0.1_r62python3 ~ / bin/repo sync so far, the study of "download AOSP source code and how to solve the problem" is over.
