NoClassDefFoundError: org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration only API 19

Question

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);

My build-gradle:

I was also facing the same issue. Try adding the following dependency:

compile 'com.android.support:multidex:1.0.1'

and in your application class add this,

 @Override   
    protected void attachBaseContext(Context base)  
    {   
           super.attachBaseContext(base);  
           MultiDex.install(BaseApplication.this);  
    }
