Das einzige Problem das ich habe, ist, dass das Feld Benutzername als „put in die Datenbank werden 0 "Ich lief durch alles und ich konnte es nicht herausfinden! Alle anderen Felder funktionieren gut!

Und schließlich die Register.php Skript auf dem Server (ich denke, das ist irrelevant, wie die Null kommt von der Android App-Seite).

Können Sie den Logcat, das Fehlerprotokoll? – OBX
es ist logcat, aber es gibt keine Erwähnung von Fehler – OBX
in der Logcat, sollte es ein Anfang des Fehlers, in roter Farbe wahrscheinlich, die Ursache der Ausnahme – OBX
