What Did We Learn from Facebook’s F8 Developer Conference?

Facebook’s F8 Developer Conference was earlier this week and it presented a not-quite-crystal-clear vision of the future constrained by a fierce competition with Snap. But that’s just the tl;dr of one fool’s opinion (that’s me). As developers with an eye on the future, what should we take away from this conference? Facebook is Extremely Concerned […]

Creating Your First Native Mobile App with Visual Studio (Part 4)

Over the past few blog posts, we have been working on creating a cross-platform mobile app with NativeScript, Visual Studio, and SQL Server – covering each and every part of the development process.

Creating Your First Native Mobile App with Visual Studio (Part 3)

In this blog post series, we are working on creating a truly native cross-platform mobile app with NativeScript, Visual Studio, and SQL Server, from start to finish, using Telerik AppBuilder. In the previous post, we finished scaffolding our app using NativeScript layouts and added some mock data to see how it all worked. Now we […]

Creating Your First Native Mobile App with Visual Studio (Part 2)

In the first post of this series, we started our “Bill Murray” mobile app with NativeScript’s tab strip TypeScript template in Visual Studio, using Telerik AppBuilder. Now it’s time to write some code to create a truly native, cross-platform app, with 100% code re-use between our iOS and Android apps. By the end of this […]

Creating Your First Native Mobile App with Visual Studio (Part 1)

Visual Studio is quite possibly the most adored IDE of all time. For years .NET developers have relied on the myriad robust features and integrations in Visual Studio to make them more productive creating desktop apps, web apps, and now (increasingly) mobile apps. In the early days of the mobile revolution, a subset of developers […]

What is TypeScript?

Even as I mature as a developer (ok, mature may be too strong a word, how about “as I get older…”), at times I still feel like a complete beginner. And these days I can attest that we noobs are feeling a bit overwhelmed with the expanding footprint of JavaScript. It’s alternately amazing and overwhelming […]

Going Offline with NativeScript

While access to the internet has never been more widely available, we still live in an occasionally disconnected world. Whether on an airplane, underground, or in a rural area on 2G, we routinely deal with varied speeds and spotty access. Yet we expect our mobile apps to continue to work flawlessly! Approximately 60% of all […]

Adding Unit Tests to Your NativeScript App

The bane of many a developer’s existence, writing unit tests is about as popular as seat belts in the 80’s. We know it’s a good idea, but how can you reach your six-pack of PBR with a strap across your shoulder? What if it were actually easy to write and execute unit tests? What if […]

A Guide to App Store Images

You’ve just finished designing, coding, and testing the next killer app. It’s beautiful. It’s engaging. It’s rock solid. The next step is publishing to the app stores. No sweat. This is when you realize there are 60+ different app icon sizes and 40+ splash screen sizes you can provide. Oh, and we haven’t even gotten […]

Willy Wonka Was Actually Talking about NativeScript

One of the most endearing films of all time, Willy Wonka & the Chocolate Factory, is that rare flick that has maintained a certain relevance for both children and adults alike. Wonka displayed a relentless, almost manic, pursuit of his vision of what a candy factory should be. Ignoring the fact that his Oompa Loompa […]

Platform-Specific Development with NativeScript

From day one, NativeScript has allowed you to leverage one codebase to create native mobile apps for multiple platforms (including the web!). It’s undeniable that writing code once and generating native apps for iOS, Android, and (soon) Windows is a tremendous time-saver. NativeScript’s robust modules abstract away platform-specific implementations and provide one clean and easy […]

Creating an Ionic Theme for NativeScript

Hybrid app developers around the world know full well the power and beauty that the Ionic Framework provides. By leveraging the best of Angular, Ionic makes it easy to create hybrid mobile apps that have a mostly native look and feel.

iOS App Distribution in 7 Steps

Distributing an app is arguably the Achilles’s heel of the iOS app development process – and Apple makes us feel dumb at times. Provisioning profiles, certificates, device registrations, app ids, oh my! Apple enforces certain requirements to make sure they know who created which apps and control which devices they run on (the app store […]

Native Mobile Maps from Telerik and Mapbox

I’m going to hazard a guess that one of the first things you did with your first smartphone was pull up a map, swipe around, and be more-than-slightly amazed at holding a virtual world in your hand. As mapping has matured in the browser, our mobile mapping apps have matured as well – from Google […]

7 Steps to Building a Hybrid Apple Watch App

Getting Started with ScreenBuilder (Session Recording)

ScreenBuilder is the newest addition to the Telerik Platform lineup, enabling you to build the vast majority of your mobile app using pre-wired screens and binding widgets to remote data sources.

Android Permissions Explained

When you develop an Android app, your users will justifiably be concerned if your app requests access to a myriad of device features and personal information. You are risking decreased app installations and increased suspicions of your app’s motives if you ask your users for personal data, contacts, access to their phone, SMS messages, and […]

Using the iOS 8 WKWebView with Telerik AppBuilder

Much ado has been made about the inclusion of Apple’s new web view (WKWebView) in iOS 8. PhoneGap/Cordova developers especially were keen to take advantage of this new high-performing web view in their apps. In this article we’ll discuss why WKWebView is important and how you can use it today with Telerik AppBuilder. What is […]

Securing a PhoneGap/Cordova Hybrid Mobile App

Watch the webinar “Best Practices for Securing Your Mobile Apps” to get some tips and tricks on mobile app security! Unbeknownst to many PhoneGap/Cordova developers, the HTML/JavaScript/CSS assets that make up your mobile app are not compiled or otherwise obfuscated when the final app package is built. Unlike the true native bits of the app […]

Using the Xcode iOS Simulator with Hybrid Mobile Apps and Telerik AppBuilder

Hybrid mobile developers have been blessed with ever-improving testing and simulation tools. Telerik AppBuilder customers are no exception, as they have come to rely on a best-in-class simulator experience along with the ability to test on physical devices and, more recently, access to native device emulators for iOS, Android, and Windows Phone. In this final […]

Using the Windows Phone 8 Emulator with Hybrid Mobile Apps and Telerik AppBuilder

The Windows Phone 8 platform is widely considered, at best, a strong third option in mobile app development and, at worst, a reasonable consideration. Most often an afterthought to iOS or Android development, Windows Phone has steadily seen a small increase in marketshare and deserves it’s fair share of investment in terms of debugging and […]

Using the Android Emulator with Hybrid Mobile Apps and Telerik AppBuilder

Starting with a recent release of Telerik AppBuilder, you now have the ability deploy your hybrid mobile apps directly to any native emulators you have installed. This means that you no longer need to access scores of physical devices to properly test your app – you can now test and debug directly on emulators that […]

Hybrid Mobile App Command-Line Smackdown

The proliferation of command-line tooling has exploded over the last few years – and hybrid mobile developer tools have been no exception.

Which Core PhoneGap/Cordova Plugins Do I Need?

The release of Cordova 3.0 brought with it a much lighter core due to the absence of basic API features such as access to the device camera, file system, and the InAppBrowser. Now of course these features didn’t disappear into thin air, rather they are now separately installable as plugins. Along with the benefit of […]
