This article is a deep dive into Android Services. Learn all about started services, bound services, and bound and started services. With source code examples and a sample app.
This tutorial is a deep dive of Flexbox layout and FlatList. It will show you how to take a wireframe and compose React Native components out of it. The code for this tutorial is on GitHub.
This tutorial is a deep dive of React Navigation, which is the way to do in app navigation. It also goes into the best practices for styling your app and how to collaborate with designers for styling. The code for this tutorial is in GitHub.
This tutorial will show you how to get started quickly with React Native for mobile app development on Android and iOS. It focuses on Flexbox layouts, Navigation, and cross platform considerations. The code for this tutorials is in GitHub.
Redux and React are things that are normally associated with web development. Redux is a beautiful design pattern that can help with any application, even native ones! I used Firebase in order to do cross platform data synchronization across web and mobile clients. I also used Firebase auth and Material Design to craft a real-world app. The code for this tutorial is in GitHub.
The best way to handle GPS is to use the “network” or “passive” provider first, and then fallback on “gps”, and depending on the task, switch between providers. This covers all cases, and provides a lowest common denominator service (in the worst case) and great service (in the best case).
Android applications run in a native Linux process, in the underlying Linux OS. This process houses activities (screens), widgets, and services (non visual long running application parts). When working with Android apps, it is important to remember to keep long running code running in threads that are not tied to the main thread or event dispatch thread, in order to get an “application not responding” error. A common mistake that is made is long running tasks are performed in this EDT/main thread, and this leads to lots of application failures.
I’ve been working with various object encoding schemes to get information transferred over the network between services and mobile apps running on Android and BlackBerry. On Android, I figured I would try using Java object serialization, and that works some of the time, and not for anything complex. I wish the object serialization and deserialization mechanism in GWT would be ported over to all these mobile environments, but I digress. This tutorial outlines the use of JSON for this purpose.
This tutorial is an introduction to the built in animation frameworks that are part of the Android UI library. Without writing any animation/drawing code, you can do 2 types of animations – layout transitions that affect ViewGroups, and sequences inside a View. You can also do frame by frame animation, but this tutorial will not cover that. The basics covered here affect layout transitions, and animation of a View itself, using tweening animation, which includes each of the following effects (or any combination) – Alpha, Rotate, Scale, and Translate.
