Android Studio'da Smack 4.1 ile XMPP Bağlantısı

Question

https://github.com/igniterealtime/Smack'dan Smack 4.1.0 rc1 ile bir XMPP Bağlantısı yapmaya çalışıyorum bu kılavuzu takip ederek https://github.com/igniterealtime/Smack/wiki/Smack-4.1-Readme-and-Upgrade-Guide Gradle'ı içe aktarın.

Bu problemle bana herkes yardımcı olabilir mi? Bağlantının çalışıp çalışmadığını kontrol etmeye çalışıyorum ..

Answer 1

sizin build.gradle içinde smack-android ile smack-java7 değiştirin. Bu Smack's README belgelenmiştir.

Answer 2

XMPPConnection sınıfına bağlanmayı deneyin.

bağlama:

XMPPConnection con = new XMPPTCPConnection("igniterealtime.org"); 
con.connect(); 

Answer 3

Bu, son FCM XMPP Bağlantı Sunucusu uygulamasının bir yükseltmesidir. Şimdi, bu proje Smack kütüphanesinin (4.1.8) bu zamanında en son sürümü kullanıyor. Android için kütüphanenin java sunucusu için oldukça aynı olduğunu düşünüyorum.

https://github.com/carlosCharz/fcmxmppserverv2

Bu Firebase Bulut Mesajlaşma (FKM) XMPP Bağlantı Sunucusu vitrin benim örnek java projedir. Bu sunucu, XMPP protokolünü kullanarak FCM CCS Sunucusu aracılığıyla bir istemci uygulamasına veri gönderir.

Ve ayrıca youtube bir video oluşturduk Ben değişikliklerin neler olduğunu açıklamak nerede.
