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.

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.

You will have to implement the OnSuccessListener Interface, just like to OnClickListener from documentation.

The solution for this problem is below

import { Injectable } from '@angular/core';
import { ad as androidUtilities } from 'tns-core-modules/utils/utils';
import { AppUpdateAvailability } from '~/app/models/interfaces/app-update-availability.interface';
declare const com: any;

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

  constructor() {
  }

  public checkForUpdate(): Promise<AppUpdateAvailability> {
    return new Promise((res, rej) => {
      try {
        const context = androidUtilities.getApplicationContext();
        const appUpdateManager = com.google.android.play.core.appupdate.AppUpdateManagerFactory.create(context);
        const appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();
        appUpdateInfoTask.addOnSuccessListener(new com.google.android.play.core.tasks.OnSuccessListener({
          onSuccess: function (AppUpdateInfo: any) {
            const UpdateAvailability = com.google.android.play.core.install.model.UpdateAvailability;
            switch (AppUpdateInfo.updateAvailability()) {
              case UpdateAvailability.UNKNOWN:
                res(AppUpdateAvailability.Unknown);
                break;
              case UpdateAvailability.UPDATE_NOT_AVAILABLE:
                res(AppUpdateAvailability.UpdateNotAvailable);
                break;
              case UpdateAvailability.UPDATE_AVAILABLE:
                res(AppUpdateAvailability.UpdateAvailable);
                break;
              case UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS:
                res(AppUpdateAvailability.DeveloperTriggeredUpdateInProgress);
                break;
              default:
                rej('App update : Something went wrong!');
                break;
            }
          }
        }));
      } catch (err) {
        rej('Err in checkForUpdate() : Code error');
      }
    });

  }
