Physische Web-android-Client bauen Fehler: com.android.dx.cf.iface.ParseException

Question

Ich versuche, Beispiel physischen Web-android-Client von here zu bauen. Nachdem in Android Studio importieren, bin vor mir diesen Fehler:

ich nichts im Code geändert habe, weiß also nicht, warum dieser Fehler. Bitte helfen Sie.

Wenn ich ändern, um die JDK-Version 1,8 bis 1,7, die Fehler Änderungen an:

Answer 1

ich gelöst es nach 2-3 Stunden.

Dieses Projekt benötigt JDK 1.7. Auf JDK 1.8 gibt es das Unknown source file : com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000) .

Warum bekam ich die com.android.dex.DexException: Multiple dex files define Lorg/physical_web/collection/Request$RequestCallback; Fehler nach dem Ändern der jdk auf 1,7 ist, weil ich vergessen habe, das Projekt zu reinigen, bevor Sie es erneut ausführen. So gab es mehrere Dex-Dateien, eine, die mit jdk 1.8 generiert wurde und eine, die mit jdk 1.7 generiert wurde.
