In Android, the concept Window seems not important anymore.
Until recently devices running Android have generally had small displays that would not be able to present multiple "windows" in a usable way. Android best supports display of a single "window" covering the entire screen at any time - along with dialogs for convenience. That window is typically managed by the system at the command of an Activity. So yes .. in general you should forget about windows and use Activities to manage the UI.

I saw some android applications that has floating window like something in windows OS (or like picture below).I had searched but i could not find any thing.Is any api or library needed or this is just styling?
You can build App Widgets. App Widgets are miniature application views that can be embedded in other applications (such as the Home screen) and receive periodic update

Hello Android developers,
Im more or less expierenced in Android programming and now i want to create an app that is allowed to access the display of another app or the activity that is less my app. Both apps should be active, should run. My app shall access the display data of the other app (also can be android system display), change it a bit and then show it again.
Is it possible without root rights?
Is there any Android support class that could help me? Which way i can go?
I hope my problem is clear and you can help me!
Ok now I have a more detailed question: How can open my app and show a transparent RelativeLayout, so that you can see what is below my app?
Thankyou a lot

If both applications are yours, you can access the other Activity using a connection between them (sockets, pipes, shared files, etc.)
If you'd like to create an overlay and display something on top of the other app, you can do that using a 'system window' popup. For example: Popup window in any app
If the other app is an arbitrary software without any modifications, such thing is not possible as it would lead to security issues. Both applications are Unix processes running in their own sandboxes without any direct communication.
In one of requirement I need to develop an application where user can launch two application in separate area of screen.
Say Application A in half of the part of screen and in rest of part other application.
I know this could not be straight way to achieve it, but is there any possibility to build such kind of app/launcher. I checked some of mobile ROM support multi application window support.
Any suggestion to achieve this.
You'd have to have this support done on system level, same way Samsung did for example. W/o this you are out of luck.
this is system level thing unless you make you own customize rom it pretty much impossible to do ,if you want to make customize rom then you will be able to do since its an system level this launcher uses system property to do so.
I want to be able to tap the statusbar and the contents in the displayed app to be scrolled up to the top.
Is it technically possible that an app intercept my tap and send the appropriate command to the active app? I have noticed for example that AntTek quick settings shows a drop-down window when swiping down from statusbar. While using the app I did also notice that even by just tapping the statusbar (before beginning to move the finger down), the app seems to already interact with the touch as it dims the screen brightness in preparation to display it's "window" (sorry I use the MS Windows term), so clearly a statusbar tap CAN be sensed by an app.
Starting from this, I wonder if such an app could then send a message to the active program telling it to scroll up.
Is that possible? And if yes, the message must be customized to a particular app (let's say the browser as the most important) or is it standardized so the apps speak the same language between themselves?
I am not a programmer so answers with codesamples might be less helpful than a plain english explanation. Finding out that is possible would lead rather to pursuing a programmer to implement the idea rather than starting to develop it myself.
Thanks :-)
There is an XPosed-module which seems to do exactly what you want.
To use XPosed-modules, you'll need to root your phone and install the XPosed-framework.
The XPosed-module is called "Statusbar Scroll to Top" and its repository can be found here:
http://repo.xposed.info/module/com.mohammadag.statusbarscrolltotop
This will work for almost all app-lists, but for example won't work for browser-content.
If you want to scroll to the top of the page in a browser, then you'll probably do best to get a browser which can do that on its own. (For example Habit Browser has it built-in and respective plugins are available for Firefox.)
Yes it is possible. HiroMacro and Frep can do this, but it requires root. https://play.google.com/store/apps/details?id=com.prohiro.macro&hl=en
(how do they simulate mouse and keyboard interactions on other applications? i have no clue :/ anyone?)
Is it technically possible that an app intercept my tap and send the appropriate command to the active app?
No. One app cannot send fake input to another app, for security reasons.
An android app comprises of several activities. Each activity display a GUI that allows the user to perform a specific task. To take the user from one activity to another, app must use an Intent to define our app’s intent to do something.
An intent can be explicit in order to start a specific component (a specific Activity instance) or implicit in order to start any component that can handle the intended action.

What I want to do is be able to start another Android sub application (which I have not written myself) to run inside a window within my main application. I would want certain touch events etc on the elements of the main app that are still visible to allow me to stop the sub application.
I've found examples of how to launch another activity using an Intent - but I have found nothing allowing me to specify that it runs in a certain window.
Is this possible at all?
The window metaphor does not exist under normal Android.
Some tablet makers have added it to their builds, but using windows would reduce the portability of your app.
