Referring to DNSSDObjects in dns_sd.h and DNSServiceResolve in MonoTouch

阅读更多关于 Referring to DNSSDObjects in dns_sd.h and DNSServiceResolve in MonoTouch

问题 I want to add reference to DNSSDObjects to a project in MonoTouch, specifically DNSServiceResolve object. I want to access DNSServiceResolve in a MonoTouch project but cant find that class anywhere. How can that be done ? 回答1: I got the functions from dns_sd.h working with P/Invokes. Most of the definitions were already done in the project zeroconfignetservices [1], specifically in the file mDNSImports.cs. Instead of referencing dnssd.dll , it is /usr/lib/system/libsystem_dnssd.dylib on iOS.

What's the strategy of DNS-SD services responding to mDNS query?

阅读更多关于 What's the strategy of DNS-SD services responding to mDNS query?

问题 I am trying to gather some information of devices connected on the wifi with DNS-SD. When I use dns-sd -B _services._dns-sd._udp (OS X)/ avahi-browse -t _services._dns-sd._udp (Linux) repeatedly to observe the published services, I get more or less output while devices(Mac and iPhone) are always connected. For example, this service(used by iTunes for Wi-Fi sync) shows occasionally while no one changes the sync setting of the iPhone. Timestamp A/R Flags if Domain Service Type Instance Name 12

Wifi P2P service discovery works intermittently

阅读更多关于 Wifi P2P service discovery works intermittently

问题 Wifi P2P service discovery is not behaving as expected. I am seeing intermittent issues where the DNSSD listeners are not called always and hence I have no clue of nearby devices running the same app. I am using the following two APIs - one to register a service to be discovered by other devices and the other to discover the nearby services running on other devices. Any idea if I am doing anything wrong here or is there some specific sequence of other android API calls that need to be made

How to change android device name used by NsdManager?

阅读更多关于 How to change android device name used by NsdManager?

问题 I am using NsdManager to register a web service on the local network. My problem is that the device name is called "android", so I can access the phone as "android.local" from my laptop. How can I change that name? I would like something more unique. 回答1: You cannot change this (on non-rooted devices). "android" is the host name of the device, ".local" is the suffix added by the mDNS (see this article). 来源： https://stackoverflow.com/questions/13796841/how-to-change-android-device-name-used-by

阅读更多关于 communication between Java server and Android client using Network Service Discovery

问题 I'm building a Java server application (running on a pc) that register itself to the local network using JmDNS, and an Android client App that should discover the java server using Network Service Discovery. When I run the android app first, and then run the java server, the app succeed to discover the registerd java server. But when I first run the server and then the android app, the onDiscoveryStarted method called but the onServiceFound method never triggered - the android app doesn't

Resolving SRV records with iOS SDK

阅读更多关于 Resolving SRV records with iOS SDK

问题 I want to resolve DNS SRV records using the iOS SDK. I've already tried the high-level Bonjour APIs Apple is providing, but they're not what I need. Now I'm using DNS SD. void *processQueryForSRVRecord(void *record) { DNSServiceRef sdRef; int context; printf("Setting up query for record: %s\n", record); DNSServiceQueryRecord(&sdRef, 0, 0, record, kDNSServiceType_SRV, kDNSServiceClass_IN, callback, &context); printf("Processing query for record: %s\n", record); DNSServiceProcessResult(sdRef);

Closed 4 years ago . I'm right now implementing the DNS-DS library "mdnsjava" into my Android-project as it's mentioned at several positions, for example here at SO: Are there any other Java libraries for bonjour/zeroconf apart from JMDNS?. While implementing, I wonder if this implementation is really

Android P2P service discovery callbacks not being called

阅读更多关于 Android P2P service discovery callbacks not being called

I'm fairly new to Android and I'm working on an application that will exchange data over WIFI direct and I would like to use DNS Service Discovery instead of pure P2P discovery to get more useful information like device "nick names" etc. So far I've followed the tutorials at http://developer.android.com/training/connect-devices-wirelessly/index.html and read through the documentation. My application seems to register it's local service successfully and the onSuccess callback from discoverServices is always called, however the txtServiceRecord from other devices (I'm using 2 devices) is never
