Digitizer is a computer input device that receives analog information, such used to capture handwritten signatures and data or images from taped papers and records it digitally thereby converting it to digital format.
Using a scanner for e-signature capture For this method of digital signature capture, sign a piece of paper several times. Use a dark, wide-tipped pen so the signature shows up well and you can pick your best version. Then scan your preferred signature. Save the scan as an image file, such as .
If no signature has been previously stored on the device, tap Create Signature, or to replace an existing signature, tap Clear Saved Signature and re-tap > Create Signature. Tap to use your camera to capture an image of your signature. (You can also Hand draw a signature or tap to choose an image on your device.)
Your question is a little too broad. Try asking a question about a specific problem, not "how do I do something general". See the FAQ for more information about how to ask a question.
Here is a vague idea though:
You'll want to have a canvas object that can allow the user to draw to the screen. Here is a link on SO about it. Android drawing a line to follow your finger
Then you'll want to output that bitmap as a file: Save bitmap to location
