I don't really think you need my help on these kind of problems though, with some proper debugging tools you should be able to find these problems easily. What program are you using to code/build/debug, Eclipse? And are you familiar with breakpoints? If not then check them out, they make debugging so much easier! Using logcat only is a pretty dang hard way to debug, check out this video on Eclipse breakpoints: [this video] And thanks for accepting the answer by the way, woohoo, my first reputation points :)

Even if you are new at programming, you could try to use an IDE like Eclipse. Using an IDE you can use the breakpoints and follow the code line by line and the variable line by line. So you will understand what happens. You could create a watch expression that will show on a tab the variable to you or use the inspect to do this. A video: [this video]
