You need to learn how to Debug in Eclipse and how to use the ADB and DDMS tools.

In order to get more details about an exception/force close you need to look for a view in Eclipse called Logcat(you will find in the DDMS perspective) there you will find a detailed traceback when/what and on what line is the issue.

For this you should read a complete article about Debugging in Android using Eclipse
