ZeroKit and Firebase Demo App First Look

If there is sensitive data to be stored when developing a mobile app, security is of utmost importance. Developers can make hackers’ work harder, but it’s almost impossible to totally prevent a data breach if they are at it. Key and encryption handling can be a real pain-in-the-ass. Storing encrypted data is one thing, but […]

When converting to Swift 3, you’ll notice that practically every file needs changes! That’s largely because, all the Cocoa API names have changed. Or to be more precise, the API is […]

RxMp4Parser for Android App Developers

More and more Android apps provide video editing based features. This library is not a complete wrapper for the most recent Mp4Parser library. However, it provides a few useful features that are usually used by these apps. If it does fit your application’s needs, feel free to implement those features based on the current implementation. The […]

A Beginner’s Guide to XML Parsing in Swift

If you are not familiar with XML, it’s basically a precisely formatted text or string, which can be parsed into an array of objects containing the precious information.

Rx Wrapper How-To for Critical Resource Tasks

Android contains several APIs that hold resources back. They need to be released before closing the current Activity or any other UI part. Doing things the old way, you are responsible for releasing these resources at the end of each activity. With complex tasks, it becomes quite hard to keep track of all of these resources. It is even more complicated when you use them in asynchronous tasks. A small programming overhead will eliminate this problem by replacing the async tasks with Rx streams and scheduling them on the background threads. So, Rx wrappers will ease thread handling. Here is how I use Rx wrappers to make them as awesome as possible:

A Native Mobile Dev’s Favorite Libraries

A junior developer starts to develop everything by himself. However, a little experience or help will teach him that it’s not useful to write every little piece of code on his own. Enthusiastic developers provide a lot of good and widely tested solutions for problems almost everyone faces during development. Using these libraries can save you […]

7 Android Logging Tools Tested & Compared

Logging is essential during development. Therefore, the Android SDK provides the public with a default logger. It is easy to use: we can add tags and also separate logs by different levels.

The SDK’s defult logger is not bad and it’s enough for the basics. But hopefully developers think logging should result in far more than just the basics.

Creating a Custom Cordova Plugin

At Wanari, we usually prefer native Android & iOS development and my colleagues have recently written quite a few articles on these topics. However, as a web developer, cross-platform mobile app development options stand closer to my heart. In this article, I provide an example for creating a custom Cordova plugin.     Cordova is a […]
