Override The Android Back Button In A NativeScript With Angular Application

Have you ever needed to perform a certain action when the user tries to hit the back button or exit out of your application on Android devices? For example, what if the user was able to back out of your application and you wanted to show a dialog. Or what if you have a video application and you wanted to pause the video when they tap the back button?

Being able to override the functionality of the back button on Android can do great things for your application as long as you don’t abuse it.

We’re going to see how to create a mobile application with NativeScript and Angular that demonstrates overriding the back button on Android, whether that be hardware or software.

TPDP Episode #18: Progressive Web Application Development

I’m pleased to announce that the latest episode of The Polyglot Developer Podcast, titled Progressive Web Application Development has been published to all of the major podcast networks.

In this episode, which is the eighteenth on the show, I’m joined by Tara Manicsic who is a Google Developer Expert (GDE) and works for Progress Software, the company behind Kendo UI. We discuss everything from where applications are headed and how they can function effectively as PWAs.

3 Of The Best Frameworks For Mobile App Development In 2018

Mobile development is a necessity for every modern business, but there are many ways to get the job done. Many will tell you to go pure native, some will tell you to go hybrid, and others will tell you to use a framework to go cross-platform native.

We’re going to review my top three picks for mobile development frameworks that will thrive in the 2018 year.

How To Come Up With An App Idea And Execute In Development

I’ve been developing applications both as a hobby and professionally for quite some time now. I’ve released top ranking mobile applications to the various app stores and even sold the rights to applications.

One question I get asked quite a bit is in regards to how I come up with those ideas and execute on them for a successful release. Being a solid developer is one thing, but having a solid plan is another.

I’m going to share my process so you can be more successful with your web and mobile application releases.

Build A Ripple XRP Wallet For Android And iOS With Ionic Framework

A few days ago I released, what turned out to be, a very popular article around developing a Ripple XRP wallet. It was titled, Create a Cross-Platform Desktop Ripple XRP Wallet with Vue.js and Electron, and it focused on cross-platform desktop application development. A popular request on Twitter was around developing a mobile Android and iOS wallet for Ripple XRP coins.

We’re going to see how to use Ionic Framework and Angular to create a Ripple XRP wallet for Android and iOS. Because our desktop application focused on the JavaScript stack, our mobile application will be able to recycle a lot of our code.

Create An Android Launcher Icon Generator RESTful API With Node.js, And Jimp

When you’re developing an Android mobile application, it is critical that you come up with a nice launcher icon for all possible Android screen densities. If you’re not too familiar with Android, there are mdpi, hdpi, xhdpi, xxhdpi, and xxxhdpi densities as of now. This number could change in the future.

Once you’ve got your icon, resampling or resizing it for each possible screen density can become a pain in the butt. Instead, it makes sense to use or create a script for this.

If you’ve been keeping up, you’ll remember I wrote about image generators in an article titled, Generating Splash Screens and Application Icons for NativeScript Mobile Apps. Since we’re talented developers, we’re going to create our own service this time around.

We’re going to see how to create a RESTful API that accepts an image and generates various sizes of that same image, bundled within a ZIP archive. We’re going to accomplish this task with Node.js and Express.

Manually Setup NativeScript Without Use Of Provided Scripts

NativeScript is great. There is an easy setup process (at least for Windows, I unfortunately don’t have a Mac so I can’t speak on the MacOS side of things) that provides an executable that helps you through all the steps of setup. Unfortunately, like any automated setup process, things can go awry and stop your excitement on starting on your native apps with some errors that have little suggestion on how to move forward. This guide will help you go through the steps to install and use NativeScript manually, so whether you’re having difficulties with the simple setup, or want to customize a few things along the way, you’re ready to rock and roll.
