Relationship between Android and Linux kernel versions

 

I. Relationship between Android and Linux Kernel

English name	Chinese name	Android version	Linux Kernel version
No	None	1.1
Cupcake	Paper cup cake	1.5	2.6.27
Donut	Donut	1.6	2.6.29
Eclair	Muffins	2.0	2.6.29
Eclair	Muffins	2.1	2.6.29
Froyo	Frozen yogurt	2.2	2.6.32
Gingerbread	Ginger pie	2.3	2.6.35
Honeycomb	Honeycomb	3.0	?

2. the download source code is divided into two parts:

1. Android source code;

2. Android kernel (Android Linux kernel );

3. How to download the android Kernel

Git clone git: // android.git.kernel.org/kernel/common.git

4. How to view the android kernel version (Code-level view)

In the kernel code directory:

Run the command: git branch-

Running instances

[Root @ localhost common] # git branch-A (view Version)

* Android-2.6.36:

Remotes/ORIGIN/head-> origin/Android-2.6.36

Remotes/ORIGIN/Android-2.6.35

Remotes/ORIGIN/Android-2.6.36

Remotes/ORIGIN/archive/Android-2.6.25.

Remotes/ORIGIN/archive/Android-2.6.27.

Remotes/ORIGIN/archive/Android-2.6.29.

Remotes/ORIGIN/archive/Android-2.6.32.

Remotes/ORIGIN/archive/android-gldfish-2.6.29

Remotes/ORIGIN/archive/Android-goldfsh-2.6.27

5. How to obtain the specified version of Linux kernel

To download the 2.6.29 kernel, run the following command (enter the downloaded directory ):

Git checkout remotes/ORIGIN/archive/Android-2.6.29 (the version branch listed above)

The kernel version 2.6.29 is downloaded.

6. How to obtain the source code of a specific Android version

For example, obtain the source code of android1.5.

Repo init-u git: // android.git.kernel.org/platform/manifest.git-B cupcake

Repo sync

 

Android 1.5: Cupcake (cup cake)

Android 1.6: donut (donut)

Android 2.0/2.1: eclair (lightning puff)

Android 2.2: froyo (frozen)

Android 3.0: gingerbread (ginger pie)

Android 3.5: honeycomb (honeycomb)

Android 4.0: Ice Cream (ice cream)

 

Essentially:

To get a branch rather than the code on the main line, we need to use the-B parameter to specify the branch name.

 

7. How to obtain all sourcecodes in the latest version of the android trunk

Repo init-u git: // android.git.kernel.org/platform/manifest.git

 

8. How to obtain the code of a project

For example, kernel/common does not require Repo. You can simply use git.

Git clone git: // android.git.kernel.org/kernel/common.git

9. list all local branches

Git Branch

10. How to obtain the code of a branch

If you need a branch code, use git checkout.

 

For example, if we have just obtained the kernel/common code, we should first enter the common directory and then use the following command:

Git checkout origin/Android-goldfish-2.6.27-B goldfish

So we built a local Android-goldfish-2.6.27 branch named goldfish, and the code was synchronized with the android-goldgish-2.6.27.
