Using Websocket on Android

This post is the sequel to this post about WebSockets. I know what you are thinking. But why? Using WebSockets is a really useful way of building realtime applications, because they provide a fast, full-duplex communication channel between the server and the client. There are many libraries out there, usually providing straightforward, easy-to-use APIs for developers […]

ConstraintLayout 1.0

What happened since the first release of ConstraintLayout? Has it changed for the better or the worse? These and similar questions will be addressed below: Introduction It’s been a while since I last wrote about ConstraintLayout and how fun playing around with it 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.

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:

Android Developers! Here are 5 of the Best Video Transcoding Libraries +1 for Only Audio!

Some Android Projects might require high or low level media processing. This article rounds up a few useful libraries, like FFmpeg, MP4Parser, Intel Media for Mobile, etc. All the libraries have both pros and cons. You need to carefully consider, according to your initial target API-s, devices, and specification, which one you’ll use . I won’t go into too much detail, the article’s main purpose is to help you decide which lib fits best for a given issue. The selected library or libraries can have great effect on the size of your final application, and will also affect the code complexity and amounts of future maintenance.

 

ConstraintLayout on Android – How Ready Is It?

Introduction to the new Android ConstraintLayout

ConstraintLayout is a new Android layout type presented at the Google IO. It has several new features including a new Layout Editor built in the new Android Studio. (currently on the Canary channel v2.2 Preview 2) The reason for this new layout is to reduce the view hierarchy’s depth and complexity. By using ConstraintLayout, you can optimize and speed up the UI rendering phase of your application. It is compatible with all the currently available Views and ViewGroups and it is part of the Android Support Library. It works down to API level 9.

How to Render More Than a Lot of Markers on Google Maps for Android

The purpose of the article is to demonstrate a method on how to extend the capabilities of the Google Maps API on Android devices. Basically, Google Maps can render only a limited number of markers over the map, let’s say a few thousand, but with larger numbers it will start to lag and will ruin […]
