Update from Google Play

Posted: February 20th, 2019Author: and

We would like to inform you that Google has updated their Developer Policy to make apps published with Google Play compliant with user Privacy, Security, and Deception policy and now restricts the use of high risk or sensitive permissions, including the SMS or Call Log permission groups.

Please review these permissions in your Appery.io project(s) on the App Settings page (Project->App Settings->Android Permissions).

If such permissions are not used by your application but are enabled, please disable them. Once done, upload an updated app version to Google Play to ensure it will be allowed by Google.

If your application requests the use of such permissions, you will be required to submit the Permissions Declaration Form to receive approval from Google Play. Once your Permission Declaration is reviewed and your app is approved for policy compliance to the Google Play Developer Distribution Agreement, your application will be published.

Note:

Completing the form is required even if the application does not use such permissions, so please select any items there and add a comment like: “I’ve selected one just to submit a form, the app doesn’t require that feature”.

How to Build a Sample Ionic 3 List App

Posted: February 9th, 2019Author: , and

This post will describe step-by-step how to build a sample app with Ionic 3 that will retrieve a list from your database collection.

  1. Create a new Ionic 3 app. From the Apps page, click Create new app > Ionic 3 (beta), give it a name, and click Create.
  2. Import the List service from any existing or newly created Appery.io database collection. Create new > Database Service, select the needed database and check the List service checkbox confirming import.
    The subfolder with the corresponding name should now have been added to the Services folder in the Project view tree.
  3. Add a model called SingleItem of type Object and 2 attributes: name and _id. Then, add the Items model of Array type and define it in the following way:
  4. Open Pages and rename Screen1 to List using the “cog” sign.
  5. Under the DESIGN tab, add a List component to the List page and delete the 2nd and 3rd items on the list.
  6. Select the List item and add the property *ngFor=let item of items. Also, set the Text property to {{item.name}}.
  7. Now, add a Button component to the page, select it, and define its Text property as Load List and (click) property as loadList().
  8. Switch to the CODE tab, click Edit internal includes, check your added list service, and save:The service with the corresponding name should now be added under Internal includes.
  9. Add 2 variables: items of type Items and listService of the type of your list service (added to Internal includes). Check the Add DI checkbox for listService.
  10. Finally, add a function, name it loadList, and define it with this JavaScript code:

Voilà!

You can now test your app. To do so, click the arrow button next to the Test menu item. In the drop-down, select Show without frame and click Launch. The page will be loaded. Now, click the Load list button. The list appears loaded with the items from the database:Note: To learn how this app can be modified to search and share data across its pages, proceed with this post.

What about iOS 11 Support?

Posted: September 22nd, 2017Author:

iOS 11 came out of beta on September 19th. But, don’t worry. The Appery.io team is close to putting the final touches on our full support for the new version of the iOS. As soon as it’s ready, we will be announcing it here. Stay tuned!

OAuth Login with Google App in Android/iOS Apps (An Update)

Posted: July 26th, 2017Author:

This blog post supplements “OAuth Login with Google App” in the Appery.io documentation.

Since April 20, 2017, all OAuth requests through InAppBrowser are blocked (see http://blog.ionic.io/google-oauth-changes/ for details). Now it’s necessary to use the Google Sign-In Cordova/PhoneGap plug-in.

So, first of all, download the plug-in and add it to the project (more details on this).  When ready, you can proceed with specifying the settings for iOS or Android apps. We’ll describe both ways and then show you how to set up your app at the end.

Google setting for iOS projects

  1. On the Google project page, go to the Credentials tab and select Create credentials > OAuth client ID
  2. In a new window, select iOS.
  3. Define the Bundle ID (you can get it from App settings > iOS binary > Bundle ID).
  4. Click Create.
  5. Now, copy the iOS URL scheme from the created Client ID:
  6. Add the iOS URL scheme as the REVERSED_CLIENT_ID parameter of the Google Sign-In plug-in and save:

Ready!

Google setting for Android projects

  1. On the Google project page, go to Credentials and select Create credentials > OAuth client ID
  2. In a new window, select Android.
  3. You will need the SHA-1 fingerprint of the certificate that you are using for signing up your app to link the client ID to the app. To get it, export your certificate (Resources > Certificates) and run the following command in the console:

    keytool is a key and certificate management utility.

    It is included in the jdk, you can install either jdk or download the keytool utility.

  4. The obtained SHA1 code should be added to the Signing certificate fingerprint.
  5. Insert the Package name (App settings > Android binary > Package name).
  6. Click Create.

Changes to make to the Appery.io project

  1. Add the button Login with Google on Device on the LoginWithGoogle page.
  2. Add the following JavaScript code to the click event:
  3. Duplicate the Welcome page and rename it to WelcomeOnDevice.
  4. Remove the JavaScript code from the Page show event (leave only Invoke service there).

Please note that the selected Android certificate will only work with the release option enabled.

Moving App Logic to the Server: How to Query the Database from a Server Code Script

Posted: May 24th, 2017Author:

The Appery.io Database provides storage for your mobile app data. You can store data such as users, orders, purchases, products or anything else. The Appery.io Database is a cloud NoSQL database and provides a very simple and elegant REST API to work with the database.

One of the most common cases for an enterprise mobile app is to create/save a new item/record and then redisplay the list in the app with the newly created item.

Accessing the database directly from the client is fine but requires two requests to the database.

  1. A request to save the new item/record into the database.
  2. Once the 1st request completes, on its success, a request to get the updated list to display in the app.

A better approach is to do both the create and list in a single request from the app. This is very simple to do from Appery.io Server Code script. The following script shows how to create a new record and then get the updated list:

In this simple script you first create a new Person object (line 8) and then do another query to get the updated list of people (line 14). The script response returns the updated list of people. This script automatically has a REST API which is the invoked from the app.

What’s most important, there is only a single request from the app to the Server Code script. A single request is usually better than two requests. Also, you can add additional logic to the script without impacting the app. For example, you can send an email when a new person is added. Or, you can send  Push Notification when a new person is added. All this can be done without impacting the app. That’s nice.

How to Add reCAPTCHA to an Ionic App

Posted: September 15th, 2016Author: and

reCAPTCHA is a nice service that usually added to a registration form and helps prevent bots from registering automatically. The service usually displays a small and easy challenge to a human but which would be difficult for a bot to answer. In this blog post we are going to show you how to add reCAPTCHA to an Ionic app.

Let’s start.

  1. Create a new Ionic app based on Ionic Blank template.
  2. Go to https://github.com/vividcortex/angular-recaptcha, download vcRecaptcha.js, and unzip the file.
  3. Inside the App  Builder, go Create New > JavaScript, name it vcRecaptcha, check Upload from file and select the angular-recaptcha.js file from your drive. For type, select Angular module and click Create JavaScript.
  4. Now, open Screen1 and add an HTML component to the page.
  5. Under the Properties panel, click Edit and add the following code:

    where 'XXXXXXXXX' is the key generated on https://www.google.com/recaptcha/admin (your key must be inside the double quotes).
  6. Switch to Scope view and add a new function, name it onSuccess, and add the following code to the editor:

    onSuccess() is the scope function that executes when the correct Captcha is entered (here, another page will open).
  7. To demonstrate this, create a new page and name it Success. Add a Text component to the page and paste Welcome! for its Text property.
  8. Also, if you want to add a solving annotating images to your reCaptcha, go to Project > Routing, click Manage dependencies for Screen1, and check reCaptcha.

That’s it. You are ready to test your app with the reCAPTCHA.
