I'm building android app. I was wondering if it was possible for a device to maintain a connection to a a WiFi lan access point and to another device using WiFi direct at the same time? I was told that this was not possible in passing but can't find any information anywhere that would agree with this statement. I can find articles about setting up Wifi Direct networks but not on lan and direct. Any help would be highly appreciated.

Some devices certified under the Wi-Fi Direct program support connections to both an infrastructure network and Wi-Fi Direct group at the same time (e.g. a laptop may support an infrastructure connection while also belonging to a Wi-Fi Direct-certified group).
You can only be connected to one network at the time. However, there is a standard called WiFi direct that will allow you to do what you are asking for, but it isn't yet implemented in Android.
Yes, using two (or even more than two) routers on the same home network is possible. The benefits of a two-router network include: Support for more wired devices: If the first router is wired Ethernet, it supports a limited number of connected devices (typically only four or five).
Wi-Fi Direct is a wireless technology that allows two devices to establish a direct, peer-to-peer Wi-Fi connection without requiring a wireless router. It's like Bluetooth in that you need to introduce each Wi-Fi Direct capable device to the other and create a connection.
Simultaneous wifi direct and network wifi is an optional feature for devices. Some devices allow this and some do not.

I have tested on a samsung galaxy s3 and it allows both, while the moto G that I tested on was not able to.
