I need to show list of all possible displays , and after that select one of them to connect with miracast. Here is my code:
private Context context;
private DisplayManager mDisplayManager;
private WifiP2pManager wifiP2pManager;
private ArrayList<WifiP2pDevice> devices;
private WifiP2pManager.Channel channel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
context = this;
devices = new ArrayList<WifiP2pDevice>();
buttonScan.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startScan();
}
});
mDisplayManager = (DisplayManager)this.getSystemService(Context.DISPLAY_SERVICE);
wifiP2pManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
channel = wifiP2pManager.initialize(this, getMainLooper(), new WifiP2pManager.ChannelListener() {
public void onChannelDisconnected() {
channel = null;
Logger.makeLog("onChannelDisconnected");
}
});
}
WifiP2pManager.PeerListListener myPeerListListener = new WifiP2pManager.PeerListListener() {
@Override
public void onPeersAvailable(WifiP2pDeviceList peerList) {
// Out with the old, in with the new.
devices.clear();
devices.addAll(peerList.getDeviceList());
Logger.makeLog("devices size " + devices.size());
Toast.makeText(context, "devices size " + devices.size(), Toast.LENGTH_LONG).show();
if (devices.size() == 0) {
Logger.makeLog("No devices found");
return;
}
}
};
private void startScan() {
wifiP2pManager.requestPeers(channel, myPeerListListener);
}
After compiling this code, i press buttonScan, and it show, that 0 displays in area. But one display was near me. But then i connected to the display (TV), entered my app, pressed buttonScan, and it shows me, that 2 displays around me (TV and display of mobile). But its bad, i need to scan all possible displays to connect BEFORE connect... So, what am I doing wrong?
