What to do if you want a food delivery from a restaurant without having such kind of service? Someone will have to go there anyway to order and bring everything you need. And what to do if there’s nobody to do that? And that’s where Postmates comes to the rescue, a popular food order app: user simply opens it, chooses some of the available restaurants and food he/she wants, and then receives it from the company’s courier. Let’s see, how to create a food delivery app, similar to Postmates.

Now it's time to make a flexible architecture for Android using DataBinding!

When you order the application development, after choosing a platform (Android, iOS, or both) you should also make a decision about its back-end (server side). In this article we will talk about an alternative to the development of back-end from scratch, namely BaaS Backendless, which is of that type of services.

The time has come to share with you this small article on testing Android app logic. It didn’t occur to me that it is a significant component of Android app development for quite a time but it’s never too late to learn, neither for you, nor for me :)

What happens within the system when a user touches the screen? And even more important — how to handle it right? The time has come to figure everything out once and for all! Today’s post is on what I’ve learned about Android Touch System and my experience with it.

Today we will take a look at a couple of quite simple examples, learn about pros and cons of what Apple has to offer in terms of animation and get ourselves familiar with some third-party frameworks I personally find to be quite useful for handling animation. I will also show you how to use UIKit Dynamics and Motion Effects available starting from iOS 7.

Apps that are using network communicate with the server by executing queries and receiving answers. Server acts as an information desk providing answers to any questions and accepting inquiries made in a certain way to further process and save them. This communication model allows your service to perform most of the required tasks. And what if you need to tell the client that the required data has already arrived? Let’s take a look at this situation using the information desk analogy.

How to save data for your mobile application? There’re three possible ways: Shared preferences/User defaults, files and databases. When choosing which one to use you should take into account the volume of data your app will work with, mobile data type and what exactly you’ll be doing with the data. Traditionally mobile software developers were using SQLite but there’s another type of the database out there called Realm and here we’d like to talk about its advantages and show how we use it in our projects.

Every time you look at those numerous lines of code with findViewById and ternary operations with visibility you want Cthulhu to finally revel across the Earth so you don’t have to see it anymore, don’t you? But trust me, there’s a way. And we will show it to you under cut.

If you work in transportations, you surely have been marveling at Uber’s unbelievable success. Currently the service is available in 67 countries. Want to take the best of it and create an Uber like app for your own company but have no idea how much does it cost? In this article we shed some light on Uber like app development.
