Android 4.0 and later support Wi-Fi Direct. However, some of 4.x devices does not support Wi-Fi Direct because of it's WiFi driver

you can check your device using the code below

mManager.discoverPeers(mChannel, new ActionListener() {
          @Override
          public void onSuccess() {
                //onSuccess
          }
          @Override
          public void onFailure(int reason) {
                //onFailure
          }
});

If your device support Wi-Fi Direct, onSuccess will be called after a moment. Otherwise, onFailure will be called.
