Please create a class

import android.content.Context;
import android.support.multidex.MultiDexApplication;

    public class EnableMultiDex extends MultiDexApplication {
        private static EnableMultiDex enableMultiDex;
        public static Context context;

        public EnableMultiDex(){
            enableMultiDex=this;
        }

        public static EnableMultiDex getEnableMultiDexApp() {
            return enableMultiDex;
        }

        @Override
        public void onCreate() {
            super.onCreate();
            context = getApplicationContext();

        }
    }

and in your manifest give android:name="packagename.EnableMultiDex"

eg:

<application
    android:name="YourPakageName.EnableMultiDex"
    android:hardwareAccelerated="true"
    android:icon="@drawable/wowio_launch_logo"
    android:label="@string/app_name"
    android:largeHeap="true"
    tools:node="replace">

Let me know whether it solved your issue.

Are you sure this fixes ClassNotFound? The documentation specifically says this addresses the dex method count, which is not mentioned – OneCricketeer Nov 29 '17 at 06:51
I faced exactly the same problem and this helped me to solve that.Let us know whether it solves his also.:) – Sachin Varma Nov 29 '17 at 06:52
Its Working fine for me. – Mithun Nov 29 '17 at 08:57

@cricket_007 it really works in some cases i saw atleast 30+ people fixed this error with this answer , SachinVarma you should give credit to me when you copy pasted answer https://stackoverflow.com/a/41479407/6478047 – Manohar Nov 29 '17 at 11:20
When he asked the question i was not able to remember the place from where i got this code,but i applied it in my project that's all i know.So i posted the answer,and after seeing your comment i searched and i was able to see that i was taken the answer from https://stackoverflow.com/questions/42106420/android-studiojava-lang-runtimeexception-unable-to-instantiate-activity-compo, there i have mentioned your answer also https://stackoverflow.com/questions/19523167/android-classnotfoundexception-didnt-find-class-on-path. Sorry at first i was not able to remember these much.But you are right – Sachin Varma Nov 29 '17 at 11:45
