I would like to create a P2P WiFi network using Android Things (5.1) and a couple of Raspberry Pi 3 or alternatively using Bluetooth. I followed the guide in the Android Developer section https://developer.android.com/guide/topics/connectivity/wifip2p.html, so my MainActivity looks like:
private class MainActtivity {
private WifiP2pManager mManager;
....
@Override
public void onCreate(Bundle savedInstances) {
mManager = (WifiP2pManager)
getSystemService(Context.WIFI_P2P_SERVICE);
....
}
}
However when I try to run the app, with WiFI enabled, the SystemServiceRegistry shows a message stating
No service published for: wifip2pand the WifiP2pManager is not retrieved.
How can I solve this issue? Does anybody know if it is possible to create a WiFi P2P network using WiFi Direct and Android Things?
As of now (Android things stable release 1.0) WifiP2P is not supported on RPI3B,Hence try to use Google NearBy 2.0 API as alternative I think it will satisfy your need.
