Problème de lancement d'application
bonjour
j essayes d'adapter le code d un tutoriel qui joue un mp3 sous android
pour le faire faire diffuser une stream radio.
le probleme est que cette application crashe avant meme de se lancer (voir image).
Par rapport au code initial de l'application, j'ai modifier deux choses.
1. j'ai totalement supprimé de code de reaction du button play
2. j ai ajouté au fichier maniste la ligne lui indiquant d utiliser internet.
voici le code source:

Si vous pensez que l erreur provient du fait que l emulateur ne se connecte pas internet, comment faire pour depasser ce probleme.
Merci
