This library is to take picture using camera from background without displaying preview.

A sample application that can be used as a template for implementing Mobile Two Factor Auth

The major drawback of authentication performed including something that the user possesses is that the physical token (the USB stick, the bank card, the key or similar) must be carried around by the user, practically at all times. Loss and theft are a risk. There are also costs involved in procuring and subsequently replacing tokens of this kind. In addition, there are inherent conflicts and unavoidable trade-offs between usability and security.

It is a library with several commonly used Input Dialogs implementations.

A Mac App, for Apk multi-channel package.

A playground for MVVM style architecture on Android.
