I'm following this tutorial on a TC56DJ device and i'm trying to initialize the scanner. getEMDKManager method always returns "NONE" as statusCode and the app crashes in onOpened (at getInstance).
I've also tried barcodesample1 as is with the same result
 
Here is my code in onCreate,
 
EMDKResults results = EMDKManager.getEMDKManager(getApplicationContext(), this);
 
if (results.statusCode != EMDKResults.STATUS_CODE.SUCCESS) {
 
  System.out.println(""EMDKManager object request failed!"+ results.statusCode);  // Prints NONE
 
}

and here is my onOpened,
 
@Overridepublic void onOpened(EMDKManager emdkManager) {
 
  this.emdkManager = emdkManager;
  emdkManager.getInstance(EMDKManager.FEATURE_TYPE.BARCODE);
 
}

The log.

Any hints?
