I have an Android app and I'm using the ZSDK_ANDROID_API.jar to print labels (Zebra ZD420).

Running the app works file but when trying to build a signed APK (release) I get the following build errors:
18:53 Generate Signed APK: Errors while building APK. You can find the errors in the 'Messages' view.com.zebra.sdk.printer.internal.ProfileHelper$1: can't find superclass or interface
