You should verify the following:

1. Copy your .ttf file to “font” folder under “assets” in the main directory
   1. If you don’t already have an assets file, right click on the main directory | New | Android Resource Directory
      - Directory name: assets
      - Directory type: assets
      - Source Set: main
      - Once the directory is created, right click | New | Android Resource Directory |
      - Directory name: font
      - Directory Type: font
      - Source Set: main
2.  Once you have verified you have your font in the right place, Pass in fontName as “font/font_name.ttf”

By default, no. If you want Setup to be successful only after Device Data collection is complete, then enable DF Sync in the SDK Config.

OnValidated handler of the Setup will be called with the corresponding error message. 

If you start ProcessBin without successful completion of Setup/Init, then ProcessBin cannot be completed. Please check the console log for error details.

If the parameter you passed to the continue, like TransactionId or Payload is invalid then, continue will throw an error.
