Fingertip drawing applications on Android?

I'm a new user to this interesting开发者_如何学Python forum!

I want start developing an application for android and before starting i want learn about some android features...

The first android feature is how to correlate finger motion on the screen with java...

Are there any source code examples that show how to draw with your finger on an android screen?

Can you suggest a good place for me to download an example?

thanks

The ApiDemos that come with the SDK have an example called TouchPaint that does exactly this... it's a simple little finger drawing app. The source is actually very easy to read and it shows all of the basics.

Check out this tutorial on drawing with a canvas in Android. There are some source code examples there for you as well.

Also, the Android developer's guide and tutorials on the Google site are great. That's what I started with.
