Is there a way to manage a debug and a release version of the same app without losing data? I'm not aware of any easy way to do get around the uninstall/reinstall process, so your options include...

I have seen it first time ... in a method signature. I tried to access a .class file. It has a method defined as below public void addGraphData(GraphData... _graphData) { } And that GraphData is nothing but POJO with getters and setters. Why is the .class file displaying GraphData... _graphData instead of GraphData _graphData ?? It's varargs and can only be used last in a parameter list.

I wish to develop an app in iPhone in which user's thumb will be scanned first. The impression of the thumb should be used as a signature for email or report. Please suggest if its possible to do or not. If its possible then are there any tutorials or link. Thanks in advance, Prerna Unfortunately no, iPhone detects touches as points, it's not sensitive enough to detect the human thumb with the fine marks of a thumbprint.
