Android – Introduction to Parallel Computing

Handling asynchronously is a ‘must’ for all mobile applications when executing any long time operation. For example, in Android, when a network operation is going to be called, it has to be executed on other thread (not UI thread). If the developers try to run a network operation on UI thread, Android OS will force… Continue reading Android – Introduction to Parallel Computing

Android – How to consume an Azure Mobile Services?

Publishing core data through web service is always a work-intensive progress because we have to build up a web server, define service interface, make data access layer and implement user management.

Android – Introduction to AndroidAnnotations, Maven in Intellij IDEA

I think, as developers, all of us want to write less code but still keep the code structure clean and clear as possible. When I develop app in Android, I always miss MVVM (WPF in Visual Studio) where I can bind control to event easily.

Android – Basic testing with unit test, android test and roboguice, robolectric, mockito

The more time developers invest for testing, the better the software is and the less annoyance developers… Continue reading Android – Basic testing with unit test, android test and roboguice, robolectric, mockito

Android – Sqlite database with ContentProvider and LoaderManager

If you follow my previous posts, you may already know that we discussed how to make an application with database in Android before in Android, Dependency Injection (IOC) with roboguice and MVVM (Model-View-ViewModel) pattern. Although the main topic in that article relates to Dependency Injection but we had also a working example which fully supports… Continue reading Android – Sqlite database with ContentProvider and LoaderManager

Android – How to speed up Android emulator?

Therefore when… Continue reading Android – How to speed up Android emulator?

Tab control is a popular component in desktop application. I think, most of desktop application contains at least a tab control in one way or another. In Android environment, we also have a tab control named “TabHost”, but since Android 3.0, it was replaced by ActionBar. In this post I would like to show how… Continue reading Android – Build tab layout with FragmentPagerAdapter, ViewPager and ActionBar
