I am developing an android application in which I need to detect palm swipe. Precisely, I want to trigger a new intent after successful palm swipe over the touch screen. I have no clue where to start for implementing the same.
Please provide some pointers or approaches which can be used to implement the same.

So I am making a simple Basketball Shoot game, that use the swipe gesture (swipe down to up to throw balls).
When I use Unity remote 4 on my android device, everything works fine, when I swipe my finger, it throws a ball according to the swipe movement.
But when I build my app, and run it on my android device, the swipe gesture works, but it throw balls in other direction that doesn't match the swipe direction.
I run my app on two different devices, and they have different directions for the same swipe movement.
How can I fix that? do I need to setup something in unity player settings?
Thanks a lot :)
I am assuming that you are using RayCast to detect swipe gesture. If that so then update your question with code snippet. We have to play bit smartly while using RayCast.
I apologize if this is a stupid question. I have only taken an introductory Java class and am a beginner to Android.
I want to track the drawing made by a finger using Swype and record each stroke as an image or vector of some sort.
Is there a simple way to record a touch movement in another application, maybe by making an application running in the background?
Thank you and I appreciate any guidance!
Touch events are consumed by the top-most view. Because swype doesn't have any kind of API you can hook into you won't be able to get that information. Input Events | Android Developers
There might be some way to create a skeleton keyboard application that captures the gestures that people make over an image of the swype keyboard that then passes that gesture to the real swype, but I'd personally be worried about copyright unless it was just for personal use.
SO i am building a game in which i want to be able to allow the user to do certain actions based on the gesture on the screen.
For example, the user makes a circle with their finger on the screen and then something will happen.
Or the user makes a triangle and then something happens..
Is there any way to detect this type of gestures?
This guy wrote an awesome post on the topic with source included:

I'm starting from scratch and I don't even know where to look.. or even what to call this.. so any help would be appreciated.
I am working with the Snake example that Google supplies and I want it to work on Android devices without physical keys. How would I be able to use touch gestures (up/left/right/down) to make the snake turn and whatnot.
Again, I don't even know where to start looking.. I'm still slowly learning my way through programming for Android.
Thanks!
You could implement View.OnTouchListener. I think this page is the one you're looking for.
I would modify it so that touching the top part of the screen sent the snake up, the left side sent it left, etc.
I would like to know what is meant by gestures in typical mobiles more specifically android ones. Android supports gesture recognition.
Is a gesture termed as when user
holds the device and shakes it(say
upwards, downwards or side- side)?
Is a gesture termed as when a
finger is placed on the screen and
traced UP,DOWN,RIGHT,LEFT? If so
what is the difference between touch
screen and gestures.
I am confused between 1) and 2) option.
What is a gesture exactly?
As I understand it, a gesture is anytime a user touches the screen and does a pre-defined motion that the system understands. I would venture to say that shaking the phone is not a gesture, but a function of detecting changes in the accelerometers.
From Android's reference web page, a gesture is a hand-drawn shape on a touch screen. It can have one or multiple strokes. Each stroke is a sequence of timed points. A user-defined gesture can be recognized by a GestureLibrary.

I see gestures as being a type of input pattern that you expect from the user. I.e., you can setup mouse gestures in web browsers to do things like going "Forward" or "Back" in the browse by doing a specific "gesture" (maybe middle mouse button click and moving the mouse left goes "Back").
I'll give a brief answer to your bonus question: Yes, it's quite possible to to character recognition from input gestures on Android. In fact, at least one major vendor has already ported an existing handwriting engine to that platform. Works beautifully, but there's a lot of legal and marketing cruft to take care of as well before it ends up on real devices :(
