How to run mobile client

• Add the following dependencies in your app level build.gradle

    .
    .

    implementation 'network.datahop.libs:datahop:v0.0.11'
    implementation 'network.datahop.libs:blediscovery:0.0.5'

• We need wifi, location, bluetooth permission/enabled to run d2d discovery
• To start the daemon we can simply do the follwoing

BLEServiceDiscovery bleDiscoveryDriver = BLEServiceDiscovery.getInstance(getApplicationContext());
BLEAdvertising bleAdvertisingDriver = BLEAdvertising.getInstance(getApplicationContext());

WifiDirectHotSpot hotspot = WifiDirectHotSpot.getInstance(getApplicationContext());
WifiLink connection = WifiLink.getInstance(getApplicationContext());

Datahop.init(
    getApplicationContext().getCacheDir() + "/" + root,
    this,
    bleDiscoveryDriver,
    bleAdvertisingDriver,
    hotspot,
    connection
);

bleAdvertisingDriver.setNotifier(Datahop.getAdvertisementNotifier());
bleDiscoveryDriver.setNotifier(Datahop.getDiscoveryNotifier());
hotspot.setNotifier(Datahop.getWifiHotspotNotifier());
connection.setNotifier(Datahop.getWifiConnectionNotifier());
Datahop.start(true);
Datahop.startDiscovery(true, true, true);
