Bonjour à tous !

Voilà je viens de commencer à développer des applications pour android et j'essaye de gérer la rotation de l'écran, donc je crées sous eclipse un second fichier layout (qui se nome "layout-land") et je fait mes interfaces (portrait et landscape)

Jusque la tout va bien mais à partir du moment ou je mets le code (dans mon cas celui pour une calculette, histoire de prendre la main avec un projet simple) et que je lance l'émulateur l'application fonctionne parfaitement au format landscape mais des que je passe en portrait il me dit que le processus à cracher et il me dit de forcer l'arrêt...

Alors est ce qu'il y a un code à mettre pour éviter cela ?

Merci d'avance,

Flyer-74

Tu peux nous montrer ton LogCat ?

[flyer74]

Oui je veux bien mais c'est quoi !?

[Sake_reflex]

Il faut aller dans DDMS ou dans Debug parfois quand ton application est lancée et normalement tu peux voir un onglet LogCat.
Si ce n'est pas le cas, Windows => Show view => LogCat.

Le LogCat te permet de voir ce qui se passe sur ton emulateur, les erreurs, les warnings etc...


Ps : enfin la manip la marche si tu es sur Eclipse.
