У меня есть 2 телефона, подключенных к WIFI. 1 из которых выполняет код. Существует маршрутизатор wify. Но почему WifiP2pDeviceList одноранговые и пустые и почему WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals (действие) не вызывается. Он печатает "CCC", "AAA", "SSS", но не "LLL"
Код выглядит следующим образом
public class WiFiDirectBroadcastReceiver extends BroadcastReceiver {
private WifiP2pManager mManager;
private WifiP2pManager.Channel mChannel;
private WifiScanActivity mActivity;
private WifiP2pManager.PeerListListener myPeerListListener;

public WiFiDirectBroadcastReceiver(WifiP2pManager manager, WifiP2pManager.Channel channel,
WifiScanActivity activity) {
super();
this.mManager = manager;
this.mChannel = channel;
this.mActivity = activity;
this.mContxt = mActivity.getApplicationContext();
Toast.makeText(mContxt, "AAA", Toast.LENGTH_SHORT).show();
}
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
// Check to see if Wi-Fi is enabled and notify appropriate activity
} else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
// Call WifiP2pManager.requestPeers() to get a list of current peers
// request available peers from the wifi p2p manager. This is an
// asynchronous call and the calling activity is notified with a
// callback on PeerListListener.onPeersAvailable()
Toast.makeText(mContxt, "LLL", Toast.LENGTH_SHORT).show();
WifiP2pDeviceList list = intent.getParcelableExtra(WifiP2pManager.EXTRA_P2P_DEVICE_LIST);
for (WifiP2pDevice d : list.getDeviceList()) { //...
Toast.makeText(mContxt, d.deviceAddress, Toast.LENGTH_SHORT).show();
}
} else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {
// Respond to new connection or disconnections
Toast.makeText(mContxt, "CCC", Toast.LENGTH_SHORT).show();
if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1);
if (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED) {
// Wifi P2P is enabled
} else {
// Wi-Fi P2P is not enabled
}
}
} else if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) {
// Respond to this device's wifi state changing
Toast.makeText(mContxt, "TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT", Toast.LENGTH_SHORT).show();
if (mManager != null) {
Toast.makeText(mContxt, "UUU", Toast.LENGTH_SHORT).show();

@Override
public void onPeersAvailable(WifiP2pDeviceList peers) {
//Log.d(TAG,String.format("PeerListListener: %d peers available, updating device list", peers.getDeviceList().size()));
Toast.makeText(mContxt, "BBB", Toast.LENGTH_SHORT).show();
//Toast.makeText(mContxt, peers.toString(), Toast.LENGTH_SHORT).show();
//if()Toast.makeText(mContxt, "nullllllllllllllllllll", Toast.LENGTH_SHORT).show();
for ( WifiP2pDevice peer : peers.getDeviceList()) {
WifiP2pDevice device = peer;
//here get the device info
String deviceaddr = device.deviceAddress;
Toast.makeText(mContxt, deviceaddr, Toast.LENGTH_SHORT).show();
}
// DO WHATEVER YOU WANT HERE
// YOU CAN GET ACCESS TO ALL THE DEVICES YOU FOUND FROM peers OBJECT
}
});
}
}
