registration failed error

[wfzwfz]

I use the TapLinx Java SDK , and develop my application based on the app sample.
I registered my app and download the license from developer center and put it in my app.
Then I run the code DESFireFactory.getInstance() But there's an error shows 
"com.nxp.nfclib.exceptions.NxpNfcLibException: TapLinX registration failed after Free Trial. Provide Valid License Key"
"at desfire@3.1.0-RELEASE/com.nxp.nfclib.desfire.DESFireFactory.getInstance(Unknown Source)"
But I don't know why. So how to solve it and continue to develop my app?

Dear wfzwfz,

As can be seen from your post, you did follow "Starting development with TapLinx Java SDK". Double check your registration API call if key data payload is put in the right order and in the right format. Grant your application the access to internet for at least one time, that app is registered.

Best regards,

This is my console log. It seems to try using offline license but failed .Because I don't have a offline key. I can't see any other information about registration ...So any idea for that?

Dear wfzwfz,

Did you provide generated key value (from inspire portal) in your API call:

// Register with a "online" license string (xxx)
m_libInstance.registerActivity( this, "xxx" );

so instead of xxx, there shall be your key value generated on Inspire portal.

The sample application seems to get the key from InspireJavaLicense.txt file in the project.There isn't a way like 

m_libInstance.registerActivity( this, "xxx" );

to input the key.I have download the InspireJavaLicense.txt from development center and put it into my project ,but the register action still failed.

Dear wfzwfz,

Please open a support ticket on nxp.com and provide as much info as possible (e.g. what registration you would like to perform - offline, online - hard coded in code or sourcing from external file, registered package name of your app).
