App Content Personalization

Android

You must implement the SMTWidgetListener in the MainActivity and set the listener inside the onCreate method.

The SmartechEventManager is used to provide widget callbacks to the JavaScript layer.

import android.os.Bundle; 
import com.facebook.react.ReactActivity; 
import com.netcore.android.Smartech; 
import com.netcore.android.contentpz.SMTWidgetListener; 
import com.netcore.android.contentpz.model.SMTWidget; 
import com.smartechbasereactnative.SmartechEventManager; 
import java.lang.ref.WeakReference; 
import java.util.HashMap; 
 
public class MainActivity extends ReactActivity implements 
SMTWidgetListener { 
 
    private SmartechEventManager eventManager = 
SmartechEventManager.getInstance(); 
 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        // Set the widget listener directly in onCreate 
        Smartech.getInstance(new 
WeakReference<>(this)).setWidgetListener(this, this); 
    } 
 
    @Override 
    public void onWidgetsLoaded(HashMap<String, SMTWidget> data) { 
        // Emit widget data to React Native via SmartechEventManager 
        eventManager.emitEvent("SmartechWidgetDataReceived", data); 
    } 
 
    @Override 
    protected void onDestroy() { 
        super.onDestroy(); 
        // Remove the listener to avoid memory leaks 
        Smartech.getInstance(new 
WeakReference<>(this)).removeWidgetListener(this); 
    } 
}

import com.netcore.android.Smartech 
import com.netcore.android.contentpz.SMTWidgetListener 
import com.netcore.android.contentpz.model.SMTWidget 
import com.smartechbasereactnative.SmartechEventManager 
import java.lang.ref.WeakReference 
 
class MainActivity : ReactActivity(), SMTWidgetListener { 
 
 private val eventManager = SmartechEventManager.getInstance() 
 
   override fun onCreate(savedInstanceState: Bundle?) { 
     super.onCreate(savedInstanceState) 
     Smartech.getInstance(WeakReference(this)).setWidgetListener(this,    
this) 
   } 
 
   override fun onWidgetsLoaded(data: HashMap<String, SMTWidget?>) { 
       eventManager.emitEvent("SmartechWidgetDataReceived", data); 
   } 
 
   override fun onDestroy() { 
      super.onDestroy() 
      // Remove the listener to avoid memory leaks 
      Smartech.getInstance(WeakReference(this)).removeWidgetListener(this) 
  } 
 
}

Javascript

Add the below listener to receive the callback in JSlayer.

SmartechBaseReact.addListener(SmartechBaseReact.SmartechWidgetDataReceived, 
(widgetData: any) => {     
  // Extract widgets from the received data 
 });

1. Get Widget By Name

Use this method to fetch a single widget by its name. The result will be returned via the SmartechWidgetDataReceived listener.

SmartechBaseReact.getWidgetByName('widget1');

2. Get Widgets By Multiple Names

Use this to fetch multiple widgets by passing an array of widget names. The widgets will be returned to the listener.

let widgets: string[] = ['widget1', 'widget2', 'widget3']; 
SmartechBaseReact.getWidgetByNames(widgets);

3. Get All Widgets

Use this to retrieve all widgets eligible for display. The SDK will return the data via the onWidgetsLoaded() callback.

SmartechBaseReact.getAllWidgets();

4. Get All Widget Names

This method lists all widget names available for the current user. This is useful for debugging or dynamic rendering scenarios.

SmartechBaseReact.getAllWidgetNames((err: any, res: any) => { 
});

Track Widget Events

The SDK automatically tracks delivery events when widgets are rendered. However, you need to explicitly log viewed and clicked events to ensure proper analytics.

Track View Event

This event is called when the widget becomes visible to the user

SmartechBaseReact.trackWidgetAsViewed(objWidget);

Track Click Event

This event is called when the user interacts or clicks the widget:

SmartechBaseReact.trackWidgetAsClicked(objWidget);
