[Ryu2000]

Bonjour,
Je souhaite rendre mon application compatible avec le plus de smartphone possible.
À la base je visais Android 2.2 est supérieur, car elle contient des Panoramas en Flash et que Flash n'existe qu'a partir de 2.2, mais en fait l'application contient d'autres choses qui peuvent fonctionner à partir de l'API 5.

J'utilise des fonctions available since API level 5 :
onBackPressed()
Account

Donc je suis allé dans default.properties et j'ai mis :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

target=android-5

J'ai créer un AVD qui avait comme target Android 2.0, mais lors le l'éxécution j'ai eu beaucoup d'avertissements et d'erreurs :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

En fait là je lance une Activity qui ne fait que :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

setContentView(R.layout.splash);

J'ai regardé, et background et shape c'est depuis l'API 1.
Mais j'ai quand même viré tout ça pour le test.

Et j'ai les erreurs suivantes :

Donc voilà si vous avez une idée de la source de l'erreur, merci de m'en faire part.
L'application fonctionne parfaitement avec des téléphones sous Android 2.1 et supérieur.

Edit :
Dans /res/ j'ai un dossier drawable et un dossier drawable-nodpi, je devrais essayer de virer drawable-nodpi.

Re edit :
Ça marche.
Bon ben vous saurez que drawable-nodpi ça fait chier avant l'API 6.
