Post Re: fatal exception asynctask #3
δεν ειναι ευκολο να το εξηγήσω. Exception έχουμε όταν σε μια μέθοδο κάτι δεν πάει καλά. Ας πουμε για παράδειγμα ότι πας να προσπελάσεις μια θεση του πινακα εκτος του ορίου του , η πας να κανει πράξη με μεταβλητή η οποία είναι null. Ο compiler τσιμπάει αυτο το πρόβλημα και μας το εμφανίζει. Εμεις ομως μπορούμε να πουμε στον κώδικα μας αν δεις αυτο το Exception να συμπεριφερθείς αλλιώς οπου θα του το ορίσουμε εμείς.

Για να καταλαβω τι παίζει με το Exception σου θέλω κώδικα και LogCat
