Wenn meine Anwendung zum ersten Mal gestartet wird, möchte ich den Benutzer auf einen Konfigurationstyp von Zeichenfolge verweisen. Ich verwende dazu gemeinsame Einstellungen. Wenn der Benutzer die Anwendung zum ersten Mal ausführt, sollte die freigegebene Einstellungsdatei leer sein. Es prüft zunächst, ob dem Schlüssel "configured" ein boolescher Wert zugeordnet ist. Falls nicht, sollte es zu der Aktivität namens preferences umgeleitet werden. Es scheint jedoch einfach darüber hinweg zu "überspringen"; anstatt zu Mittag oder zum Frühstück zu gehen. Ich habe sogar versucht, die gemeinsamen Einstellungen ohne Erfolg zu löschen. Irgendeine Idee, was das Problem sein könnte?Gemeinsam genutzte Java/Android-Einstellungen - Keine Anweisung zum Korrigieren der Aktivität
