I already enabled multiDexEnabled truein my gradle. Need some help to resolve this problem. Thank you.

yes, multidex could resolve your problem. May be this is happening because of you have added some analytical library initialised in application class. Further you can comment it incase if don't have to add multidex. — Kirankumar Zinzuvadia, Jul 13 '17 at 07:45

In build.gradle file

    dependencies {

       ...
        //Multi Dex
        compile 'com.android.support:multidex:1.0.1'
       ....
    }

In sample application class

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

then clean & build project
