I am integrating Card.io in my android app and I want to remove the paypal logo. I searched stackoverflow and got to know the usage of EXTRA_USE_CARDIO_LOGO.
Setting this to true or false, shows either Paypal or Card.io logo. My client requires that there should be no logo at all. Any help?
Update on this answer - as of 4.0+, card.io now supports full removal of the card.io logo with EXTRA_HIDE_CARDIO_LOGO.
Josh from card.io here. There is no way to entirely disable logos.
Jeff Brateman's answer above is partly correct. The PayPal logo is actually shown in 2 places, the card scanning view and the card details entry view. In order to hide both of them you need to add two putExtras to your scan intent:
scanIntent.putExtra(CardIOActivity.EXTRA_HIDE_CARDIO_LOGO, true);
scanIntent.putExtra(CardIOActivity.EXTRA_USE_PAYPAL_ACTIONBAR_ICON, false);
