SDK Initialization

Since the WebView library is an extension to core functionality, you need to initialize native SDKs just as before in order to start using the library:

Insider.Instance.init(this, "<your-partner-name>"); // ^^Android
Insider.initWithLaunchOptions(launchOptions, partnerName: "<your-partner-name>", appGroup: "<app-group>") // ^^iOS

After that, you can wrap your webView instance to have the library intercept calls made from web page:

Possibly in one of the activity class in your app, you can do the following:

import com.useinsider.insiderwebview.InsiderWebView;

final class AppWebViewActivity extends AppCompatActivity {
  
  private WebView webView;
  
  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    InsiderWebView.INSTANCE.setupWebViewSDK(webView); // ^^ 
  }
}

or in the view controller class if it is an iOS application:

import InsiderWebView

final class AppViewController: UIViewController {

  @IBOutlet weak var webView: WKWebView!
    
  override func viewDidLoad() {
    super.viewDidLoad()
    Insider.setupWebViewSDK(on: webView) // ^^
  }
}

The wrapping mechanism dynamically injects a proxy object that exposes the public methods of the native SDKs via the window.insider object once the DOM is fully loaded.

const insiderID = await window.insider.getInsiderID();
console.log(insiderID);
