当数据完全使用Google的Nearby API传输时，Discoverer如何从Advertiser获得确认？

// 初始化Nearby API
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
        .addApi(Nearby.CONNECTIONS_API)
        .build();

googleApiClient.connect();

// 发现设备
Nearby.Connections.startDiscovery(googleApiClient, "myServiceName", new ConnectionInfoListener() {
    @Override
    public void onConnectionInitiated(String endpointId, ConnectionInfo connectionInfo) {
        // 发送连接请求
        Nearby.Connections.requestConnection("myEndpointName", endpointId, new EndpointListener() {
            @Override
            public void onConnectionResult(String endpointId, ConnectionResolution result) {
                if (result.getStatus().isSuccess()) {
                    // 连接成功
                    Log.d("Nearby", "Connected to " + endpointId);
                } else {
                    // 连接失败
                    Log.d("Nearby", "Connection failed");
                }
            }
        });
    }
});
