I am new in android development ,My question is
what does it mean to have an android app with a control panel , Is it possible to control app after release ?
usually when somebody wants to make a mobile application, he creates a control panel using any back-end (php, java, node.js ...etc)
so he can control the API (if your app uses API call), he may also want to disable the application, so in each run in the application side, an API call will be invoked to check for availability.
you can do more complicated things but that is the basic

I am looking for a method that allows me to press freely on the Android screen. Simply put, it would emulate what a person can do to move on the Android device
I want him to press the buttons of this game. I want to make a bot.
To get the control of the keystrokes from a background app you need to be root. Instead of that, you can use monkeyrunner to make scripts using Python. Another option is to use direct commands in ADB, as stated in this answer. Every option needs to be connected to a computer via USB cable.

You'll either want to use WebSockets or clientside polling.
There's a few java libraries out there to help abstract you from the underlying mechanics which can fallback to polling if websockets are not supported by the browser:
cometd
atmosphere
DWR's reverse-ajax
spring mvc
Im sure there's more but that'll get you started :)

I am developing a web application that will be sold later on, and was wondering how to add the concept of license to it, so that I can avoid it's piracy, and it can be used for given period of time only?
You can have a centralize licence server , have a DB to check user's status , expose this thing using webservice so that any of your app can consume it.
I've seen Java enterprise tools do the usual serial number/license file thing. Worked pretty well for them. All you'd need to do is put some static code in the application that would execute when the JavaEE container loads the WAR file and have that check the serial number.

I want to create a website for users to upload videos, but I want to do some compression/conversion on the client-side first before actually uploading to my servers. This should cut down on upload times I hope.
My inital thought is to make a Java Applet, since I imagine Flash wouldn't have ffmpeg on the client-side. I'm not sure what version of Java to use, or whether to use Java Web FX. I haven't touched Java in years, so I don't even know what IDE or SDK to use (I'm on a Mac).
