I really appreciate your time and effort to answer me, I really do but as I've mentioned in my first post im a newbie ,and tasks like "Simply drop the listener on onUnequip, db query etc.". sound something like this to me (会意字 / 會意字) .The "way" i ve only used Eclipse since now, was just reading a ready code from here and just learn to understand +,- lines in order to make it work and I do it successfully,if only you could edit my code(cuz you teaching me how to do it will probably take time ).If you happen to have time and willingness to help i can post my code here. Thanks in advance :)
