Ich bin frischer zu Android, ich entwickle Android App für POS-System.Iber ich habe Android Demo-App für POS (Point of Sale) System vom Hersteller erhalten.Ich habe seine Bibliothek hinzugefügt zu meinem Android-Projekt. Aber Drucker funktioniert nicht für meine App, aber die App funktioniert ordnungsgemäß.Wie Drucker Sdk POS-System Android App

1.kann ich Hersteller-App als Modul in meinem Projekt hinzufügen?
2.how Fügen Sie diese Codes in meiner Anwendung, und andere besondere Möglichkeiten, es zu tun
