Hello σε όλοι την παρέα, είναι το πρώτο μου post και θα ήθελα να ρωτήσω τους εξής προβληματισμούς μου:θέλω να φτιάξω μια τρίλιζα εφαρμογή σε Android ώστε να επικοινωνεί με bluetooth μεταξύ δύο κινητών,έχω βρει τους ανάλογους κώδικες τόσο της τρίλιζας (TicTacToe) όσο και και του bluetooth το πρόβλημα μου είναι το δέσιμο όλων αυτών ώστε να βγει το ανάλογο αποτέλεσμα.χρησιμοποιώ το netbeans σαν περιβάλλον εργασίας.γενικά είμαι νέος σε σχέση με τις Android εφαρμογές όσο και στην java!από όσο γνωρίζω ο emulator του netbeans δεν υποστηριζεί bluetooth!ευχαριστώ εκ των προτέρων!

Ψαχνω να κανω κατι αντιστιχο αλλα με wifi...Που βρικες τον κωδικα του bluetooth μηπως βρω εγω για το wifi??? Ευχαριστω...

Καλησπέρα snookeraas
δυστυχώς ο αναρτημένος κώδικας δεν είναι ο σωστός για αυτή την δουλειά που προαναφέρω, σ' αυτό το link θα βρεις αρκετές πληροφορίες για την τρίλιζα. Εγώ δυστυχώς δεν έχω χρόνο για ψάξιμο για το θέμα και έχω κολλήσει!! πάντως θεωρώ ότι έχει αρκετή δουλειά για να τα συνδέσεις όλα αυτά.

http://developer.android.com/resources/ ... index.html

λοιπόν από ότι χαζό είδα το πρώτο είναι το connection για Βτθ το οποίο κάνει on/off , scan , connect.......
ενώ το δεύτερο είναι το game αλλά είναι γραμμένο σε java applet άρα για να δουλεύψει μέσω internet (explorer). To project έχει αρκετή δουλειά .... πρέπει να καταλάβεις πως κάνει connect και πως μεταφέρει δεδομένα από το ένα στο άλλο. και δεύτερον να μετατρέψεις το java applet σε java android. Δηλαδή άμα πάρεις τον κωδικά που έχεις για την τρίλιζα και την τρέχεις στο Esclipse/netbeans αποτέλεσμα δεν θα πάρεις ποτέ γιατί αυτός ο κώδικα είναι για άλλο λόγο φτιαγμένος και όχι για android κινητά αλλά για να τρέχει στο pc. Ελπίζω να ξέρεις java γιατί copy/paste άκρη δεν θα βγάλεις.
