Solved:

Step 1: create MyApp class as follows:

public class MyApp extends Application {

@Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this); // this is the key code
    }
}

Step 2: Add the name property to the app in the manifest as follows:

<application
        android:name=".MyApplication">

In Android 9 likely to help adding to manifest into "application" tag:

<uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />

add this to gradle.build:

defaultConfig {
...
minSdkVersion 14
targetSdkVersion // your version 
...

// Enabling multidex support.
multiDexEnabled true
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

In some cases, this could be a MultiDex issue. Try this in your application class. That is in App.java which extends Application:

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this); // this is the key code
}
