apply plugin: 'com.google.gms.google-services'

in may case i do this and its work fine and menifast file

  <application
    android:allowBackup="true"
    android:icon="@drawable/logo_ew"
    android:label="Darzee.co"
    android:roundIcon="@drawable/logo_ew"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:replace="android:label,android:icon"
    android:name="myapp">
    <activity android:name=".Starter.Loader">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

and class to add in manifest file

package ...........;

import android.content.Context;
import android.os.Bundle;
import android.support.multidex.MultiDex;
import android.support.multidex.MultiDexApplication;
import android.support.v7.app.AppCompatActivity;

import com.google.firebase.crash.FirebaseCrash;



public class myapp extends MultiDexApplication  {
@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

}

Will try this and let you know. Thanks in advance – Jack N Feb 05 '18 at 04:23 — Jack N, Feb 05 '18 at 04:23

Multidex should be enabled and if you have to explicitly enable multidex for API <= 21

In Gradle File :- Add like this.

android {
    defaultConfig {
        multiDexEnabled true
    }
}

Depdencies section add this line:-

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

In Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

Moreover make sure you didnt missed anything from here https://developer.android.com/studio/build/multidex.html

And finally Clean and Build the App

adding this line in Manifest giving red error android:name="android.support.multidex.MultiDexApplication" > — Jack N, Feb 03 '18 at 05:47
