General information

• SDK/Library version: 5.5.1
• Android Version and Device: Android 6.0 on Lenovo Vibe K5 Note

Issue description

We are integrating card.io sdk in our own library. We distribute the library to third party vendors to integrate it into their applications. Using following code to start card scanning :

                Intent scanIntent = new Intent(AddCreditCardActivity.this, CardIOActivity.class);
                scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true);
                scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_POSTAL_CODE, true);
                startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);

But getting following exception :
