how to detect number gesture in android

I am trying to detect when a user draws a number on the screen, for example, number one can be translated as a top to down movement with a reasonable angle (+- 10 degrees on the y-axis), what I am doing is checking the direction of the motion and giving it an angle range to check the line within. this technique usually works for most digits.

for more complicated numbers I am dividing the resulting shape into lines based on the direction on movement, for example two is a result of the following lines: - line with direction North east and an angle between 10 and 30 degrees with the x axis - line with direction South east and an angle between -10 and -30 degrees with the x axis ....

Is there an easier way to do this, or maybe there is something already out there which do this :) , I am worried about checking errors in the motion that might happen and should be tolerated, such as unexpected slight finger movements

It sounds like you should be using the android.gesture library. This lets you create a library of gestures as resources in your program, and provides the API for detecting the library of gestures.
