I want to make a program that recognize a button that is in the League of Legends client

I want to make a program that recognize a button that is in the League of Legends client, and when the queue's button shows up the mouse instantly click on it.
Its a sort of a AutoAccept Client...
There is already a program that someone did, but it has so many unnecessary things and it does not work very well....
How do I do to recognize a element inside a program to make my mouse move there when it shows up?
I can try to code this in any language, just gimme a tip pls

You can create a program that takes a screenshot every 100ms, use a recognition algorithm of your choice and then (optionally) performs a mouse click. There are enough libraries that can screenshot for you, you should be able to recognise the button by colour and location and every language should have some method of controlling the mouse.

Sikulix (can be paired with python) is a perfect tool to use for this. It scans over your screen constantly, and if the image in question pops up (the accept button) you can click on it.
You will have to take a screenshot and likely store it as .png so the program knows what it is looking for.
Google Sikulix.

How handle headphone button clicks in Java (computer)? No smarthphones related

There's a way to handle headphones button clicks in computer (not smartphone) with Java?
The usage is very similar to Android, which by pressing the button some event is fired.
There's not much info about this, then I thought a way to perform this could be interpret the bytes of the moment of the click, and based this, do something. This "could works" but I don't know if something changes by the button click in a computer, as happens in smartphones.
So is possible handle headphones clicks in computer?

How to detect long presses of the volume key in a service?

I want to detect long presses in volume key in a service. Here are my options:
A) Let the user control volume from the lock screen
I wan't to detect if the user has held down the volume button in a service while the screen is off. I already tried (for 2 days) doing it with contentObserver, but the problem is that contentObserver detects volume changes, and volume doesn't change when the screen is off. Is there any way I can let the user control volume from the lock screen?
B) Detect long press for volume button from service
How can I do this? Are there any broadcast receiver's that I can use while the screen is off? Is there a way to implement the dispatchKeyEvent in a service?
I have seen this, but for me the second answer doesn't work in the background. I think the easiest way would be option A because I already have everything set up for when the user changes volume, so can I let the user control volume from lock screen? If not, is there anything else I can do?
Thanks so much,

Android: Unexpectedly Quit When Trying to Switch Activity

I'm new to posting, but have been using the site for help for a while now. So thanks for that!
I'm working on a new app, got everything running well. It's a kids' soundboard. 2 pages of imagebuttons in a relative layout, with onclick listeners which triggers SoundPool.
My question is this:
in testing I've discovered if you're finger is anywhere on the screen where a button is not (say pressing on the background) and then you try to touch a button (multitouch) ... the button press doesn't register. Any way to fix this?
Thanks!

You have to cover additional event types for multi-touch, if you are not covering below Actions, you are not covering multi-touch
MotionEvent.ACTION_POINTER_DOWN: This event happens for any additional finger that
touches the screen after the first finger touches
MotionEvent.ACTION_POINTER_UP:This gets
fired when a finger is lifted up from the screen and more than one finger is touching
the screen.
The explanation is quite tedious. I suggest you to google multi-touch for android. One helpful link is: http://android-developers.blogspot.in/2010/06/making-sense-of-multitouch.html

regain focus after java.awt.Robot.keyPress()/mousePress()

I writing an application which controls another application by using the keyboard only. To more concrete, the application simulates key presses and mouse clicks when a certain key is pressed on the keyboard. For example, pressing on the 'x' key simulates a mouse click on the [X] in the rop right corner, followed by a little sleep of 2 seconds and an 'enter' to confirm the exit dialog. Pretty easy. I am developing this application in Java.
Sending a key press or a mouse click is very easy with java.awt.Robot. I am facing one little problem. Say I have configured a key which will click somewhere on the screen. The problem is that consecutive key presses aren't catched anymore, as my application lost its focus caused by the mouse click outside it's window.
My question now is: what is the best way to be sure that my main application keeps the focus? Is there a way to focus my application again after the key presses and mouse clicks are sent out? Is there a better way?
Thanks in advance.

If your application lost the focus. because you or your Robot clicked to somwhere else, the Robot must click on the application again before sending a new key. In c/c++ you could force the focus to the application (a non-trivial task), not in Java!

You might want to take a look at Component.requestFocus() to see if can do what you want.
Be aware however that window focusing has very platform dependent behaviour, so you will probably need to do quite a bit of testing to ensure that your code does what you want in all circumstances.

I managed a way to prevent applications from losing all focus in Java.
By placing a WindowFocusListener on the frame (or dialog) and calling setVisible(false) followed by setVisible(true) in windowLostFocus the component will re-appear as soon as it is dissapears (not the prettiest solution but it does work).
By then calling component.requestFocus() your robot should be able to continue where it left off
