How to emulate android phone operations into emulations in desktop

Is there a way to emulate whatever operation we perform on phone to be displayed in desktop/laptop.
When my physical device is connected to my desktop/laptop, i want an emulator like feature displayed, where whatever operations i perform on phone should be displayed in the emulator.
Can we do this?
If we have any such feature, can they both be synched? meaning if i press some operation on emulator, the operation should be performed on phone.
I heard that, these can be supported like cloud based platforms like perfecto, xamarian, seetest etcc...? How they are achieving this?

Have you tried Genymotion Link HereIt is good emulator where you can download any one model of the phone and you can do whatever you like on phonebo.
other one is Mobogenie,these are two sort of emulators with different operations.

Play store app is used to remotely project your android device on a bigger screen ,but main problem is that your phone must be rooted.
If you are using lollipop see thisHere,it has inbuilt feature

Modify firmware of noname android tablet: first steps

I want to develop a HTML5 app to control doors, lights and other things in my garage. The frontend of will get displayed on a 24/7 turned on screen, that really only displays the app (kiosk mode). So there will be really only the app, no browser controls like back and forth button or url bar, and also no notification bar or back and home buttons of the device. Just the app.
For this I considered 2 options:
Doing it with a raspberry PI & connect a touch screen to i
Doint it on a dead cheap noname Android Tablet
Since the 2nd option is much more elegant from the hardware point of view (everything I need is already built in) I decided to try this first and bought a 70 USD Prestigio Tablet.
But since I'm no android dev, I'm not sure how I can even modify the stock firmware that's currently installed on the device.
As far as I can see, the bootloader is unlocked and ready for flashing a modified firmware image.
And here comes the question:
How can I get the device's currently installed firmware image? Do I have to contact the manufacturer for this or can I extract it from the device directly?
If I get the firmware image, how will I be able to modify files in it?
Or do you think I got the wrong route?

You need to find sources of firmware for your specific device. I bet manufacturer would not provide them. For Nexus devices it is easier because there is AOSP (android open source project) which gives you an opportunity to build a firmware. You can also check specific forums like 4pda.
But there is another way - to make a KIOSK mode for your device example. I'm not sure how does that fit into requirements. Also You can make your app as Launcher app and live with that :)

Any Way to Run Android App in tablet Like Phone Same As Possible in IOS

I want to Ask One Question that is More Important For Android & IOS.
We see in IOS You Can Run IOS App (Created By IOS Phone only) that app Run in Tablet
Device & work As Iphone As shown in Image.
Is there Any Way to Run Android App (Created By Android Phone only) that app Run in Tablet Device & work As Android Phone As shown in image.
is this Possible in Android!
Any help?.

Android actually handles this better than iOS, it scales the app up. Any app on the Play store which isn't being filtered will work on any Android device.
In iOS you have different views for your iPad/iPhone on Android you use Fragments to acheive the same result see Designing for Handset and Tablet.
Personally its better on Android as you can reuse componentized UI.
IF you really want to make it look like a phone app, you can use scaled mode, (if you target your app against gingerbread targetSdk="10") then Honeycomb+ will present the users with scaled mode similar to the iOS thing. I by no means recommend this! It is the worst UX you can give your users!

How to project an Android phone to projector in real time?

I want to project the screen of my phone using a projector. So far, I've seen some who did it by installing an application on their PC to get a live view of the phone's screen and then connecting the PC to a projector.
Now, I am wondering if I can connect my phone directly to the projector? Of course, that is assuming that I have a micro USB to VGA adapter. Is this possible? What application do I need to let my phone communicate to a projector? How do I do this?

There is no standard on external displaying for android, yet. Many today's model support HDMI, for some platform, system just mirror the phone screen onto projector (like Toshiba), some provides vendor specific API to control displaying (like Moto), some simply cannot control so far (like HTC).

Android - capture screen of phone as a movie

for the documentation of a project I would like to record the screen of my Nexus One as a movie or at least in form of a lot of images, which I can convert into a movie. Is that possible? Is there an app for it? For the moment I only know about this screen capture functions in the SDK's tool directory.

I've use two tools and both work well:
Androidscreencast fps 4-5
Droid#Screen fps 30

Do you need it from the device itself, or would from an emulator do? Here is a Nexus One Emulation Skin.
Here is information about the Dalvik Debug Monitor which claims to:
which provides port-forwarding services, screen capture on the device, thread and heap information on the device
(emphasis is mine)
I am not an Android Developer, so I can't comment on the usefulness of the tool.

As far I know you can only record screen of an Android device from a PC.
You need to use a tool that will put the phone's screen onto PC.
For this you can use Droid#Screen . I use this tool for presentation purposes. Than on PC you use whatever screen recording app.

It is raithe handy to use android 4.x builtin method via adb shell screencap. I wrote a basic PyGtk adbcap wrapper to make it even more simple to use.
