I need to fake the speed of the movement of the phone in the vehicle - (no accelerometer).
I need to be able to press the button on the phone "Start Engine" , "Stop Engine" and then "Speed up", "Speed down" somewhere in between.
I'm new to Android so any help will be much appreciated.
Cheers
EDIT:
I mean UI Buttons.
I need to tell phone it is moving even though it is not.
So something like maybe send fake GPS coordinates in a loop or something??? But then how do I change speed.
If you're talking about physical buttons that you could actually press, then you could use a BroadcastReceiver which has a filter of android.media.VOLUME_CHANGED_ACTION to do whatever you want when pressing keys. However, I don't think you could manage that much actions with just volume up and down. If you're talking about buttons on UI, then just put the button on UI and use OnClickListener of each button to do what you want.

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.
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,

Please, I guess how it is called: an on-screen floating message with small arrow, they used to show to user what button to push when he sees the program for first time. They are usually with text "press this button to..." or "here you can get this.."
How to implement it in android application?
edit: I implemented some buttons on screen, and they say that it is not clear what they are for. I want to show user, when he (she) run the program after update, that this is a button and it is for...
maybe u could make a a whole new UI over ride for floating display or make a
activity fully transparent with a limited window size
and over lap it over ur previous activity
I am trying to develop an application in which I want to know when the camera button(if the phone has one),has been pressed for feature phones like Series60 using J2ME.I dont want to take a snapshot or take a video.I just want to know when the hardware button has been pressed.
I have been unable to find a proper way for this.Your help is greatly appreciated.
Create a canvas, listen for keypresses and output all events to the screen. If no event occurs when you press the camera key then you can't do it.
I'm trying to make an application where the user can override the default behaviour of the volume up/down buttons (as well as the screen on/off button - is this possible?). Anyways, using some code along the lines of the following I can do this:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
super.onKeyUp(keyCode, event);
if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)) {
//this is where I can do my stuff
return true; //because I handled the event
}
return false; //otherwise the system can handle it
}
But I would like it to be possible even when the application is not open, hence why I'd like to set up a broadcast receiver or maybe stick something in a service to make this possible.
Thanks for any help.
as well as the screen on/off button - is this possible?
Fortunately, no.

This is not possible for the volume buttons.
For example, AndroSS allows you to override the camera hardware button to take a screenshot.
That is the camera button. If the foreground activity does not consume a camera button click, that gets turned into a broadcast Intent, which other applications can listen for. This behavior is unique to the camera and media buttons and is not used with any other hardware buttons.
this isn't a very good idea. this means every time you press the volume up/down keys you're going to capture it regardless of where you are. what if i want to change my ringer volume? media volume? app that uses the rockers for other uses? it just won't work well and just aggravate people. plus, i'm not sure if its doable.
This is not (easily) possible, because the "onKeyDown" method is overriding Activity.onKeyDown(). For this reason, you have to have a foreground activity to receive these function calls.
I don't have any experience doing this, but you would have to dig a bit deeper into writing your own hardware key intercept/handler functions, since you wouldn't be able to access the one from the activity class.
This probably won't do what you want, but if you make an IME, the IME can capture the volume +/- buttons, and do whatever it wants, like remap to other button presses. For instance, I have modified a Gingerbread-style IME to turn volume +/- buttons to do page up/down in the Kindle and Overdrive apps.
