Launching MiniApps
Android
When a Container is generated, it will create one Activity for each MiniApp included in the container. For example, if you have a MiniApp named Hello, the container will create an Activity-extending class named HelloActivity. It will also be declared in the AndroidManifest.xml file of the container so that you can launch it from your mobile application without extra setup.
All of these activities are stored in the com.walmartlabs.ern.container.miniapps namespace.
To launch a MiniApp, all you have to do then, is start its corresponding Activity.
You can also pass initial properties to a MiniApp, which will be provided to the JavaScript MiniApp as properties in the componentWillMount React lifecycle. This might be useful if the MiniApp needs data when first launched.
Call the following static method of the ElectrodeMiniAppActivity class.  
The first parameter is the Intent instance that you will pass to startActivity, while the second parameter is a Bundle instance containing the data to provide to the MiniApp as key:value pairs.
public static void addInitialProps(@NonNull Intent intent, @NonNull Bundle bundle)
The generated Activities are very basic, and might not fulfill more advanced needs. If you need to use your own Activity subclass to host a MiniApp, you can directly extend the ElectrodeMiniAppActivity class and override the methods to your needs.
Note Be sure to override the following method and return the String corresponding to the MiniApp name hosted by this Activity--using the previous example, we would return "Hello".
protected String getMiniAppName()
If you cannot extend your own Activity from this one (you might already have a deep inheritance chain and Java does not support multiple inheritance) but roll your own, or host the MiniApp in a Fragment instead, then you'll need to use ElectrodeMiniAppActivity as a template to roll your own class.
iOS
When a Container is generated, it provides one UIViewController for each MiniApp included in the Container. For example, if you have a MiniApp named Hello, the container will create a UIViewController that contains the Hello miniapp--and it's the same UIViewController that you are already familiar with.
To launch a MiniApp, all you have to do then, is
Present its corresponding UIViewController by calling [[ElectrodeReactNative sharedInstance] miniAppWithName:@"<your-mini-app-name>" properties:nil]
You can also pass initial properties to a MiniApp, which will be provided to the JavaScript MiniApp as properties in the componentWillMount React lifecycle. This might be useful if the MiniApp needs data when first launched. To do this, pass an NSDictionary to the parameter property.
The generated UIViewController is basic and might not fulfill your advanced needs. If you would like to use your own subclass of the UIViewController, you must override viewDidLoad: in your UIViewController as shown below:
- (void)viewDidLoad {
    [super viewDidLoad];
    UIViewController *viewController =
    [[ElectrodeReactNative sharedInstance] miniAppWithName:@"<YourMiniAppName>" properties:nil];
    viewController.view.frame = [UIScreen mainScreen].bounds;
    [self.view addSubview:viewController.view];
}
