J'ai eu affaire à un problème qui ne cesse de revenir et je suis très frustré. J'essaie de me connecter à ma base de données via un template webservice php que j'ai trouvé en ligne, en lui envoyant JSONObjects. Je reçois toujours une exception IOException ou ProtocolException lorsque j'essaie d'obtenir un code de réponse du serveur avec la cause «Fin de flux inattendue». Le message d'erreur est vraiment énigmatique et je n'ai aucune idée que l'erreur est dans le Java ou le code PHP. J'ai posté le code, vous pouvez jeter un oeil:ProtocolException: fin inattendue du flux

?>J'apprécie vraiment toute aide que vous pouvez donner. Surtout parce que je suis toujours un Noob dans le développement Android et PHP.
Je crains que cela ne fonctionne pas. 'java.io.IOException: fin de flux inattendue sur Connection {192.168.1.146:3306, proxy = DIRECT @ hostAddress = 192.168.1.146 cipherSuite = aucun protocole = http/1.1} (recycle count = 0)' sur la même ligne – MatejS
bien cela a fixé les données n'étant pas envoyées au serveur. maintenant le code php a un problème ... essayez de supprimer ceci: echo json_encode ("Status: 200"); – djodjo
