Unable to find the class on dex path list

I see a lot of questions like this but none of them helped me to solve the issue. What's my issue is Android Studio able to build apk successfully but when I run it on my device it crashes.

java.lang.RuntimeException: Unable to instantiate application io.tutorial.app.App: java.lang.ClassNotFoundException: Didn't find class "io.tutorial.app.App" on path: DexPathList[[zip file "/data/app/io.tutorial.app-1/base.apk"],nativeLibraryDirectories=[/data/app/io.tutorial.app-1/lib/arm64, /data/app/io.tutorial.app-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]

    at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:74)

And below is the part of manifest file. 

<application
    android:theme="@style/AppTheme"
    android:label="@string/app_name"
    android:icon="@mipmap/ic_app"
    android:name="io.tutorial.app.App"
    android:allowBackup="true"
    android:supportsRtl="true"
    tools:ignore="GoogleAppIndexingWarning">

    <activity
        android:theme="@style/AppTheme.NoActionBarFullScreen"
        android:name=".ui.activity.SplashActivity"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

Instant run is turned off. Tested after invalidating caches and rebuild project. Generated signed APK and tried but same issue. I used analyze APK in Android Studio and I found there are two dex files 1.classes.dex 2. classes2.dex.

Below is the Part code of App.java class

public class App extends MultiDexApplication {
@Inject
Cache cache;

public void onCreate() {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    super.onCreate();
    initRemoteConfig();
    Injector.getInstance().init(this);
    Injector.getInstance().appComponent().inject(this);
    initFabric();
    initRealm();
    initPicasso();
    initRemoteConfig();
    initAds();
    initOneSignal();
}

If you have any class that is extending default Application class then change it as below

public class App extends MultiDexApplication

or you override attachBaseContext as below:

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