A week ago I started implement Chat System to my app using Smack API (4.1.8 version). And It works well on Lolipop device and Marshmallow too. But on Kitkat( API 19) I get exception NoClassDefFoundError LogCat:
Process: mobi, PID: 23510
java.lang.NoClassDefFoundError: org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration
at mobi.networking.ChatXMPPConnection.connect(ChatXMPPConnection.java:76)
at mobi.networking.ChatXMPPService.initConnection(ChatXMPPService.java:80)
at mobi.networking.ChatXMPPService.access$100(ChatXMPPService.java:36)
at mobi.networking.ChatXMPPService$1.run(ChatXMPPService.java:112)
at java.lang.Thread.run(Thread.java:841)
So what is it on the line 76(the first line):
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setUsernameAndPassword(mUsername, mPassword);
configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
configBuilder.setResource("Android");
configBuilder.setServiceName(DOMAIN);
configBuilder.setHost(HOST);
configBuilder.setPort(PORT);
