So I want to create a button which always flash if my boolean is set to true or with a timer. My first idea was to use the "on click" animation but I don't know if it would work fine. If you got an idea of how to make a flash animation please tell me.

I am a beginner in programming and I don't know much about it. I was asked to figure out how to "Manipulate an Android smartphone to do the following":
1) Create a button that would generate a callback (for example turn the screen from black to white)
2) Control the hardware of the device (Switch on the camera flash light, switch off the light)
I Would appreciate any help as I don't know what steps I should take to achieve this as I am an absolute beginner.
1)Change background after click
2)How to use camera
But first follow Android training to understand how Activities works

But But using rotateAnimation bringed some problems, such as system performence. I want to do shaking effect on the drawable of ImageView. How can I implement is? Any help is grateful!
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 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
