use Android Native code (JAVA) in NativeScript

Question

i want to use native android code in my NativeScript app to check if there is update available in play store.

I am using official android docs.

Support in app updates Android

The native java code is below

 // Creates instance of the manager.
AppUpdateManager appUpdateManager = AppUpdateManagerFactory.create(context);

// Returns an intent object that you use to check for an update.
Task<AppUpdateInfo> appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();

// Checks that the platform will allow the specified type of update.
appUpdateInfoTask.addOnSuccessListener(appUpdateInfo -> {
    if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
          // For a flexible update, use AppUpdateType.FLEXIBLE
          && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
              // Request the update.
    }
});

and NavtiveScript code is below

import { Injectable } from '@angular/core';
import { ad as androidUtilities } from 'tns-core-modules/utils/utils';
declare const com: any;

@Injectable({
  providedIn: 'root'
})
export class AppUpdateService {

  constructor() {
  }

  public checkForUpdate() {
    try {
      const context = androidUtilities.getApplicationContext();
      const appUpdateManager = com.google.android.play.core.appupdate.AppUpdateManagerFactory.create(context);
      appUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo =>  {

      });
    } catch (err) {
      console.log('Err in checkForUpdate() : ', err);
    }
  }

}

and i am getting this error

JS: Err in checkForUpdate() : Error: Cannot convert object to Lcom/google/android/play/core/tasks/OnSuccessListener; at index 0

Can anyone tell me what i am doing wrong.

You need to pass the marshaled (converted from Java to JavaScript) native Android listener as shown in this documentation seciton. In your case, you should create a success listener with the rules shown in the article.
