Potential memory leak in Mifare Lite SDK v 4.4.1610

[arturonaredo]

Hi there,

Using the app with leak canary several times, after closing the activity the library is registered, got a warn about a memory leak within your library.

Attached you'll find the screenshot of leak canary trace.

Please let me know if I can give more information.

cheers
