When you are working on Android apps, you can easily remote-debug on Chrome. In your project folder, you should find a /www/ directory. First, you need to download and install Eclipse ADT Bundle. The bundle includes the Android SDK tools, Eclipse IDE with built-in Android Developer Tools.
We also show you how to integrate an API with such Android applications by leveraging the power of the RapidAPI‘s API marketplace. NativeScript is one of the finest frameworks for developing mobile apps using web technologies. Like React Native it allows developing high-performance mobile apps for both Android and iOS using web technologies.
The application data with the help of a web API one can either use a backend solution component or a cloud storage service. The remote storage approach allows managing larger databases and supports multi-user apps. Shyam is the Founder of Radiostud.io, a content-lead innovation studio, focusing on showcasing use cases of emerging technologies. To build this app using the Ionic framework, you need to set up some tooling. So how about building an Android app that lets you instantly generate a QR code from an URL. Before you even wonder about the nitty-gritty details of generating the QR code, let us remind you that the RapidAPI’s API marketplace has many APIs to help you with that.

Follow along with the steps below to set up a new Ionic project and build the Android app’s code. The Ionic framework acts as the glue between the Android platform, Angular, and Cordova. The resulting hybrid app feels just as good as a native app. A regular user would never be able to make out the difference. The Android ecosystem supports the concept of hybrid apps, which is a wrapper over the native platform. It mimics the UI, UX, and all kinds of hardware and network interactions, just like how you would use a native Android app.
Through customization native plugins, they can access the native features of mobile devices like camera, touch ID etc, without the core code being connected to the device. Here, the main namespace is defined to be pl, standing for “Public Library”, with the three subnamespaces model, view and ctrl being initially empty objects. We put this code in a separate file initialize.js in the ctrl folder, because such a namespace definition belongs to the controller part of the application code.
- Since the introduction of smartphones, the industry has changed revolutionarily.
- I suggest you check MVC pattern in Extjs 5 and above.
- We have created the SignUp screen and also linked it to home page.
Run The App And Get The Code
All the features and functionality provided by app.js can found in the App.js docs. Notice, however, that the Local Storage technology cannot be used for larger data sets, or for business-critical apps. In these cases, you would rather use the IndexDB API or a remote storage solution like cloud storage or a back-end DBMS.
Create a controller script called controller.js and include it in index.html. In controller.js, we’ll define the controller logic to read email and password and store it in firebase. The data-target attribute is used to link screens together. Add data-target to the SignUp button on the home page to link to this screen. If you browse the index.html file and click on the SignUp button on the home page it will redirect to the SignUp screen.
Defining And Instantiating A Class
A few minutes later, your android .apk file will be available in your project directory. We have two ways in which we can publish our app in tabris. We can either build it locally or using the cloud build service. In the src folder, you will find app.js, this is where our app script goes we can also link more js files in our app by creating a js file in the src folder and linking them. Also we will learn how to add plug-ins to our app through this file in later chapters. The package.json file describes your application and its dependencies.
Add Side Navigation
The primary target of the BlackBerry back then was the business professionals. With more and more investment in advanced devices, BlackBerry soon earned the title of the “mainstream” smartphone brand. Now we will look at how to publish our app using the tabris cloud service. App ID — this is a unique ID for your app to be identified by mobile OS incase of updates and other services on the internet.
Browse the index.html page and click on the SignUp button. If all goes well, the newly added user will show up in the firebase user list. Next we need to add a SignIn and SignUp button on the home page. All contents need to be defined inside an app-content div, hence create the app-content div and place the buttons inside it. You would need to add an “Export/import data” function to the app, which should not be a big thing.
Try it out what happens whehn you omit this code line. You’ll get errors messages stating that these objects are nod defined. HandleSaveButtonClickEvent reads the user input data from the form fields and then saves this data by calling the Book.saveRow procedure. A class-level method Book.createTestData for creating a few example book records to be used as test data. A class-level method Book.saveAll for saving all managed Book instances to the persistent data store.
It displays a text box to accept the domain name and a submit button to trigger QRickit API call. Below the button is a display area that shows the generated QR code. A service is an add-on module, used as a library across the code. You will define the logic inside this module in a little while. This will create a new blank project called “qrcode.” It automatically creates the project main folder named “qrcode” and the subfolders within. Android Studio version 3.0 or above, installed on your development computer.
The above html code is similar to the SignUp screen. What we have so far is a Home page with a link to SignUp and SignIn screens. We have created the SignUp screen and also linked it to home page. We’ll also require the firebase simple login script.
