What actual launchers are open-source? I need launcher for 2.3+, but not launcher-plus or ADW, because they are not supported already. Stock ICS+ launcher is not compilable for 2.3.
according to the list on wikipedia , only a few of the launchers are open source.
however , a launcher is a very simple app . the UI itself is the one that makes the difference.
if you wish to start from scratch , you can test out a demo of a launcher made by google :

I'm programming an android launcher for kids. I want my launcher to be the default launcher automatically when I start my app. And when I exit my app, the old launcher is set as the default launcher again.
I read that this has not been possible for some time because of safety reason. But in the Samsung Kids Launcher it is possible.
I have found some work arounds - like opening the settings or open the launcher-chooser.
I don't like these solutions because it's very inconvenient and the settings are difficult for some people.
I found code but the code was very old and doesn't seem to work anymore.
I found a function that allows me to query whether my app is set as the default.
And I found two function for going in the settings.
ACTION_APPLICATION_DETAILS_SETTINGS
ACTION_MANAGE_DEFAULT_APPS_SETTINGS
But these settings are not the right one (very unspecified)
I found this articel:
how-to-set-default-launcher-from-setting-programatically
But I haven't used it to run yet.
Can you help me?
ps: I am a beginner in Kotlin and Android programming
The application list in 2.3.3 looks like this where is the code of that?

That is the TouchWiz UI, which is a proprietary Samsung interface, and AFAIK it is not open source, so you will not be able to find the source code online.
On the other hand, you could try looking into the open source launchers available, and their themes. A good one to start with would be ADW.
Is it possible to configure the Android OS to run only a single app?
Basically what I want to do is customize an Android device so that it boots up and runs one application only, and for that application to be switched to the front of the screen automatically. Also, when it gets closed, to be started up and switched to again. Any ideas?
Thanks,

One method is to get the source of Android and write your own custom ROM of Android as Octavian wrote.
Another alternative would be to write a custom home app that, well, isn't really a home app (but replaces the default home app intent). See SlideScreen as an example of a non-traditional "home" app.
Yes it is possible. You have to fetch yourself the source codes for Android and basically create a custom ROM. After applying all desired modifications you bake your ROM and install it to your device.
Pretty much all you need to know about the source and the process of compiling the sources are located at Android Sources. You can view the source codes from your browser by following this link.
Hope it helps you a bit. Good luck.
My goal is to modify the Launcher application and dynamically modify and change the theme.
I saw several 'home' apps at http://www.cyrket.com/p/android/com.stain46.taghome/. It looks like they took the default Home(Launcher) and modified it. How did they do that? What do I need to modify to achieve the same thing?
I have done this with the ICS launcher. You also need to do quite a number of code changes to get it to compile as a normal app because it uses a lot of private internal APIs (despite what Google may have implied). You also need to change the package name. There are two limitations I've found:
There's a filter called TableMaskFilter that isn't available to normal apps. I think this allows the app drawer to be semi-transparent, but I removed uses of it and it looks fine I think.
More critically, it appears there is no way to replicate the widget-adding experience because it requires a permission that only system apps can have. See this question.
Anyway, I put my source here. It compiles and works on the official Galaxy S2 4.0.3, but if you try to add widgets it will crash.
Note, when you're changing the package name, there are places that Eclipse's refactor doesn't notice (e.g. XML layouts). I recommend you do a global text search/replace instead.
The standard Launcher is open source so you can definitely grab it and modify it the way you want. For your app to be used as the Home Screen you will need to specify the correct Intent filter in your AndroidManifest.xml and the user will have to choose your app when they press the Home button. Why don't you grab that code, play with it and come back when you have more questions and more of an idea of what you want to change.
Here i found one stable version Launcher2
I have sharing that GitHub repo. HERE
WIKI of this project :
This project contains the code for the Launcher app that ships with Android Jelly Bean (API 16).
Some minor changes were required from this source code to remove the use of private APIs. These changes have been marked by "// AOSP Change"
I want to have my own Launcher Application for Android
in other words , I want my own Application to run directly after booting , instead of the Launcher app
as I am not running Android on a Mobile phone , and I don't want Android's Home GUI
also I want to change the app in the source code , before compilation
I have tried to Simply replace files under "/packages/apps/Launcher" with my HelloWorld App
then running this command "mmm packages/apps/Launcher"
but It didn't work
So any book/tutorial/advice that covers this point ??
Thanks in advance
Android was designed to be so modular that it supports what we want without any tweaks !! maybe little tweaks in your program only
Android doesn't go for a specific Launcher app in predefined location and run itin fact you can have multiple Home Screen installed .. each App identifies itself somewhere in it's code that it is a Home App Then Android in booting decides which home App to load
Demo # http://developer.android.com/resources/samples/Home/index.html , which is included in the SDK samples too
This should not present any great difficulty to you, Android has provisions for this and there are many third party launchers available. There is an example at developer.android.com that will show you exactly how to implement and deploy your home screen replacement app: Home - Home | Android
