Mobile Services Android SDK with Offline Incremental Sync, Soft Delete, and Android Studio Migration

Posted on 18 februar, 2015

Program Manager, Azure App Service
Today, we present to you Mobile Services 2.0.2-Beta Android SDK. With this release, we introduce two new Offline features: Incremental Sync and Soft Delete. In addition, we've updated our SDK to support Gradle.build and Android Studio. If you have been following our Android SDK, we announced future support and Offline with our 2.0-Beta release back in August followed by Carlos’ posts, Futures support and breaking changes in the Mobile Services Android SDK and Offline support in the Azure Mobile Services Android SDK. Since then, we have been working in collaboration with MS Open Tech towards a better Offline experience for our Android users, and here are our updates.  

New Features and Bug Fixes in 2.0.2-Beta

Support for Gradle.build and migration to Android Studio

Android Studio 1.0 was officially released on 12/08/2014, and Android recommends a migration to receive the latest IDE updates. We have renewed our portal, quickstarts, and tutorials to work with Android Studio. For existing Eclipse users, you can follow this simple 4-step instruction to migrate your project from Eclipse to Android Studio. For those who prefer Eclipse, our latest SDK along with its .jar artifacts can be downloaded at aka.ms/iajk6q. Our Android SDK is now also available through jCenter – the new default repository Android Studio comes with. Instead of downloading our SDK, Android Studio will do this for you with some small changes to your project: 1. In the project’s build.gradle, make sure jCenter repository is included in build.
buildscript {
	repositories {
	    jcenter()
	}
    }
2. Then, in the dependencies section of the app’s build.gradle, add the following.
compile 'com.microsoft.azure:azure-mobile-services-android-sdk:2.0.2-beta'
3. When you sync the project with these gradle changes, Mobile Services Android SDK will automatically get pulled into your project.
Note: If you only see your gradle files when you Open an existing Android Studio project, it is most likely your “path to Gradle project” at the Import Project from Gradle window is set to the project’s gradle folder as a default.
gradle
You can instead Import project (Eclipse ADT, Gradle, etc.) to fix this problem.
