From Android SDK it is clear that gesture library should be put in a raw folder in resources or it could be just a separate file in private or public folder, but what is the gesture library format?. You can browse Android SDK here that describes only high level design.
I still cannot find gesture library format but I saw on the market there are many applications that uses gestures.
My first clue was to use Gesture Builder from Android example SDK.
It is located under
Lets take a close look:
GestureLibrary lib;
// create lib instanse from file name pass empty file
lib = GestureLibraries.fromFile(new File("gestures")));
..
lib.addGesture("gesture's name", gestureProcessor); // adding
lib.save();
// We could build gesture object from overlay
private class GestureProcessor implements GestureOverlayView.OnGestureListener {
public void onGestureStarted(GestureOverlayView overlay, MotionEvent event) {
}
public void onGesture(GestureOverlayView overlay, MotionEvent event) {
}
public void onGestureEnded(GestureOverlayView overlay, MotionEvent event) {
mGesture = overlay.getGesture();
if (mGesture.getLength() < LENGTH_THRESHOLD) {
overlay.clear(false);
}
}
