This should tell you EXACTLY what's null.

[android-developers] Re: Null Pointer exception in Location Manager
Hi,,
If i click redbutton I need to display latitude
if i click greenbutton i need to display longitude
How can i did that..! please give any solution..!

Your code doesn't seem to assign any values to redbtn and greenbtn.
Then you call methods on these objects - perhaps they are still Null at that
point?
