How use Repo tool in the local AOSP?

I'm working on AOSP, which I got from an OEM (without any CVS like Git or Repo). So I tried to get all Android projects using repo init ...
I followed all the docs but most of them talks about the AOSP mirror, How to track the Android project with repo?
Thank you.

If you have received all the source code without and VCS (Git or Repo) like say as a tarball then you cannot use the repo, and if you create manifest by yourself also it is too much work for almost no result.
Instead, create a new Git/Gerrit repository and use the same. All review and CI/CD can be done via the same.

Upload all projects to one github repository

I have several projects on my laptop. I would like to upload all of them to GitHub and in one repository called Android-projects. After searching the web and being bombarded by different material I got confused. How can I do that? I didn't quite understand the answers found on this website. All my attempts failed.
I have GitHub Desktop and Git Shell installed on my laptop, but don't know how to use them.

Nothing much to do there:
Create an empty directory and add it to git or create a project on github and clone it to get the empty directory
Add your projects one by one to that directory and checkin
NOTE: Tracking changes will become a bit tedious with this appropriate. You will need to be careful if you are working on multiple projects at the same time.

In the main project folder where all your android projects are present, initialize a git repository there. git init
now create a repository on github.
Finally, add (push) your code to github.

Continuous integration with jenkins using android studio

I am new here to develop android application with android studio.
I created sample basic application, from this i got the project structure of the application with build.gradle files in each module(which is different from eclipse).
Then I successfully commit the code and push the entire project code to git repository by using Version Control System (VCS) in it.
I need to configure my project with jenkins server for continuous integration.
Can any one give me the step by step procedure, how to configure android studio project code (which is commited in git repository) with jenkins server.
So far i didn't find any clear procedure to configure android studio code with jenkins server for continuous integration.
Thanks in adavance

Unfortunately for you, this isn't a "Tutorial" site. If you have a specific issue, people will help you. But for a tutorial, google around some blogs.
Based on your description, you need to:
Configure some triggers (prolly SCM change, or timer based)
Perform GIT checkout
Perform Gradle build step
Decide where to Archive your artifacts
Do that, and when you have a specific issue, then ask a specific question

Android Source download

Hey guys I am new to porting android os. I am trying to download android source and wanted to know which git repository should I download for kitkat. And alos I want to download the source in GIT windows as I do not want to use linux terminal and repo for downloading the source.
Also, will downnloading https://android.googlesource.com/kernel/msm/+/android-msm-hammerhead-3.4-kk-r1 give me the source or will https://android.googlesource.com/platform/build/+/master give me the source?
Note: I have a very limited download limit at high speeds so I only want to download the relevant source files. No prebuilt Images or and device Images. I just want to download the source for stock kitkat android and use it in ubuntu for further building.

I think that you don't understand the organization of the Android source. It is a forest of git repositories, maintained, as CommonsWare says, with a tool called "repo". Theoretically, you could clone each of the, approximately, 450 git repos, separately. I suspect it would be pretty hard to do.
When you download the source, you will get all of the versions, tagged appropriately. You need only checkout at the right tag.

You could try github, to download zip files of the branch you require. It also seems to have android kernel files, but you need to search for what you need.
The android kernel msm (for qualcomm) source code
https://github.com/android/kernel_msm
The android source code
https://github.com/android/platform_frameworks_base
The website says it is a mirror of the google server. Which means it should work.

Do I need SVN to download this project?

Android newbie here and would like to create a basic app using the AndriodPlot library.
The instructions to download are:
svn checkout https://androidplot.jira.com/svn/ANDROIDPLOT/
trunk/Examples/Quickstart Quickstart
Is there a way to download without SVN so I can get started?
If not, what SVN and how do I use it?
I assume it is some sort of version vcontrol but after Google-ing SVN, I am getting a lot of different answers and it is not clear what I am suppose to do...
Any point in the right direction to download this is greatly appreciated.

Yes, you need SVN to download this project.
What is ment by SVN is Subversion.
Depending on the platform you are using, you have to install a Subversion client. Under linux distributions, just search for the subversion in repository.
Under Windows and Mac OS X you'll find a graphical client, that will suit your needs.

You could download all the files manually or work on individual files e.g. https://androidplot.jira.com/svn/ANDROIDPLOT/trunk/Examples/Quickstart/src/com/example/MainActivity.java
but it's gonna be easier to just install svn and then checkout the repository and get a copy of the files on your machine.
Red bean did a good intro and guide when I was learning it http://svnbook.red-bean.com/en/1.1/ch01.html
And PS. learn GIT (better and now widely used)
