I appear to be crashing Gesture Search. Does it support the (valid) case where there is no suggest_icon_1 column?

Yes. What message are you getting in the logcat when it crashes?

Do you see this gesture technology making its way beyond just Android? I personally think that Google instant provides a more robust solution simply because its faster to push a letter than to draw it

You need to install Gesture Search on the device or the emulator for the API to work.

Hi! Im an IT student. I was hoping to get an I advice from you, currently me and my THESIS partner are studying android for our THESIS (a subject where we create or either enhance application) and we chose this Gesture Search Application as our topic. and as part of this subject , we are to create a prototype of this application. Can you somehow suggest me a good tutorial or Instructions for creating a prototype for this application? Sorry, If I may bother you. It's my first time in doing an android application. Any help from you will do great for our project. Thank you!! and God bless!
