Android Network est inaccessible - ENETUNREACH
Je rencontre une erreur étrange sur mon application Android. Je teste avec un serveur local utilisant Xampp. L'application consiste à récupérer des enregistrements d'une base de données et à les stocker dans le téléphone.
Le problème est que j'ai testé l'application dans un Motorola XT550 avec Android 2.3.6 et dans mon Sony Xperia S avec Android 4.0.4 et que l'application fonctionne parfaitement. Mais lorsque je le teste avec un Samsung Fame avec Android 4.1.2 (le téléphone de mon client), cela ne fonctionne pas.
Voici le LogCat:

J'ai compris quel était le problème! Le Samsung Fame n'était pas connecté au Wi-Fi . Il n'avait pas Internet.
Vous pouvez également ajouter un chèque pour la connexion Internet avant de faire toute demande afin que l'utilisateur puisse se rendre compte que l'Internet n'est pas là.
Utilisez le code ci-dessous et s'il renvoie false show Toast/Alert.
private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager
= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
Avoir un cas lorsque mon application se connecte puis éteignez wifi> crash de l'application et il ne peut pas aller à l'intérieur de la commande catch Exception.
veuillez vérifier la connexion Internet/WiFi sur l'appareil
