Learn How to Show Information in Ionic Pop-ups

Posted: June 5th, 2019Author: and

In this post, you will learn how to add information to a pop-up in an Ionic application.

Setting Up the App

To start with, let’s create a new Ionic app.

  1. From the Apps page, click Create new app > Ionic, give it a name, and click Create.
  2. Open Pages and go to Screen1. Under the DESIGN tab, add a Text component to the page, select it, and define its Text property as Username: {{username}}.
  3. Next, drag and drop an Input component to the page and set username as its ng-model.
  4. Add one more component to the Screen1 page, a Button with Text: Edit and ng-clickedit().

   The page UI should look like this:

  1. Now, in the Project view, open the Project > Model tab, create a new model of Object type, and name it Global. Add a string parameter to it named username
  2. Next, add a new variable, name it global, and select Global for Type under the SCOPE tab of the index page: 
  3. After that, switch to the Screen1 page, and under the SCOPE tab, add a new scope function named edit and provide it with the following code where the added global variable in the template of the popup is defined:

    Note, that in the code, any title can be provided and any HTML code can be added for template.

And…we are done!

Using the App

Now, to check the app, click Test. In a new window, put in Jane for Username and click Edit. The popup with this username will appear:

To enter a different name, just type it in and confirm by clicking OK. The local variable will be modified and the output can be instantly seen:

BTW: If you are into customizing your UI, here is a piece of good news. You can easily customize the looks of your pop-up:

How to Build a Sample Ionic 3 Search App

Posted: February 28th, 2019Author: , and

This is a continuation of the post How to Build a Sample Ionic 3 List App. In this document, we will provide step-by-step instructions on modifying your Ionic 3 list app so that data can be shared between its pages.

Remember, you can only proceed with the steps in this post only after you have made sure the application from the previous post works as expected.

  1. To begin with, go to the Databases tab and open the database to be used in the app. Make sure the needed collection has a column of string type named description. If needed, create it by clicking the +Col button and filling it with data:
  2. Once done, switch to the Apps tab and open the Sample Ionic 3 app created in the previous blog post. In the Project view tree, click Model. There, define the models so that they look like the following (note that, here, the SingleItem model is renamed to Item):
  3. A Query service from the collection should be imported in this step: Create new > Database Service; in the new window, select the database and check the Query service checkbox of the needed collection. Click Import selected services to confirm: The subfolder with the corresponding name should now have been added to the Services folder in the Project view tree.
  4. It is time to add a new pageCreate new > Page, set the page name to Details, and confirm by clicking Create Page.
  5. Under the PROPERTIES tab, change the Navbar Text component to Details.
  6. Drag and drop a Text component on the page and define its Text property as {{name}} selecting h1 for the Container property.
  7. Now, add another Text component to the page and set its Text property to {{description}}:
  8. Switch to the CODE tab, click Edit internal includes, and, in the pop-up window, scroll down to find { NavParams } from “ionic-angular”. Then check it and confirm the selection by clicking Save:
  9. Then, proceed to the Variables section adding and defining variables as follows (ensure the private navParams variable is checked in the Add DI checkbox):
  10. To finish with the Details page, add a new function to it, name it constructor, and define it with this JavaScript code:
  11. In the next step, some changes to the existing List page should be made. So, in the DESIGN view, under the PROPERTIES tab, select the Navbar Text component and rename it to List.
  12. Now, place the Input component on the page and define its [(ngModel)] property as query.
  13. Modify the existing List item by adding a new attribute (click)navCtrl.push(“Details”, item):
  14. Rename the Button Text property to SEARCH and change its (click) attribute to search() that will initiate navigation to the other page (Details) of the app (if you decide to keep the list functionality in the new app, create a new button for search so that there will be two of them):
  15. Once done, open the CODE tab and click Edit internal includes. Check 2 dependencies: { NavController } from “ionic-angular” and your added query dependency (the last on the dependencies list) in the Dependencies pop-up window. The List service can be unchecked now if not used for the modified app.
  16. Save. The services with the corresponding names should now be added under Internal includes:
  17. After that, add 2 variables: query of type String and queryService of the type of your query service (added to Internal includes). Make sure the Add DI checkboxes for private navCtrl and queryService variables are checked. (Delete the listService variable if it will not be used in the app.)
  18. Finally, add a function to the page named search and define it with this JavaScript code (the loadList function will not be used so it can be deleted):

    Voilà!

    The app is ready for testing. Click the arrow button next to the Test menu item. In the drop-down, select Show without frame and click Launch. The List page will be loaded. Enter the name of the item from your database collection (for example, Coat) and click SEARCH. The item Coat will be returned on the page. Then, click this item to open the Details page with the item description:

    Note: You might also want to leave the List service functionality created earlier. In this case, both List and Query services should work as expected.

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 Cordova App Fast

Posted: June 12th, 2017Author:

One of the core components in Appery.io platform is a cloud build service which builds a binary file (hybrid) for iOS or Android. Appery.io leverages Apache Cordova (PhoneGap) to create a binary file. Launching the build process is very simple. Right from inside the App builder, clicking the Export button you will see the option to create a binary file for iOS or Android.

Export menu

Export menu

Once Binary (.ipa) or Binary (.apk) is selected, the build process starts. The build process usually takes one minute. When the build is completed, the file is downloaded to your computer. From there you can publish the app to an app store, using the standard publishing process for each store.

  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.

How to Install and Use the Cordova Background Plugin for Route Tracking

Posted: December 21st, 2015Author: and

Every Appery.io app comes with the Apache Cordova library automatically installed. This means you have access to default Cordova APIs such as Camera, Contacts, Geolocation, and more. Many users also wanted to add 3rd-party Cordova plugins to the app. To make this process very simple, we’ve added a simple wizard. In this tutorial you are going to learn how to upload a Cordova plugin to your app and use it. You will build an app that will track your route and draw it on a map. The app will do this in the background. (This is a popular feature in fitness apps.)
