Android App funktioniert auf Emulator, aber nicht auf einem echten Gerät

Question

Gerade schrieb diese einfache App zum Testen, eine Schaltfläche, die die Ausgabe mit einem spellcheckersession anzeigen.

Es funktioniert gut auf Emulator aber funktioniert nicht, wenn ich versuche, die App auf einem echten Gerät (Note2 laufenden android4.4.2) zu starten.

Kann mir jemand helfen zu verstehen, warum?

Für was es wert ist, habe ich es gerade geladen und lief es auf einem Samsung S5. Weitere Informationen würden helfen, wie lädt es, kommt Ihr Gerät als verbunden? Wie weit kommst du?
