You have arrived at the source repository for the Salesforce Mobile SDK for Android. Welcome! Starting with our 2.0 release, there are now two ways you can choose to work with the Mobile SDK:

• If you'd like to work with the source code of the SDK itself, you've come to the right place! You can browse sample app source code and debug down through the layers to get a feel for how everything works under the covers. Read on for instructions on how to get started with the SDK in your development environment.
• If you're just eager to start developing your own application, the quickest way is to use our npm binary distribution package, called forcedroid, which is hosted on npmjs.org. Getting started is as simple as installing the npm package and launching your template app. You'll find more details on the forcedroid package page.

After cloning the SalesforceMobileSDK-Android project from github, run the install script from the command line:

./install.sh

This pulls submodule dependencies from github.

(Windows users: run cscript install.vbs from the command line instead.)

SmartStore Enhancements

• FTS 5 is now supported.
• We've added a new index type for JSON1.
• We've added a new API to support deleting soup elements by specifying a query.
• We've added a new optional parameter to our query APIs, called selectPaths.

SmartSync Enhancements

• SmartSync now provides a cleanResyncGhosts method for removing ghost records, that is, records that don't match sync criteria or have been deleted from the server.

SalesforceReact Enhancements

• SalesforceReact now supports deferred authentication.

Library Upgrades

• The Instant Run feature on Android Studio is now supported.
• We've replaced Volley with OkHttp for networking.
• We've updated React Native to version 0.27.2.
• We've updated SQLCipher to version 3.4.

Other Technical Improvements

The Salesforce Mobile SDK provides essential libraries for quickly building native mobile apps that seamlessly integrate with the Salesforce cloud architecture. Out of the box, we provide an implementation of OAuth2, abstracting away the complexity of securely storing refresh tokens or fetching a new session ID when a session expires. The SDK also provides Java wrappers for the Salesforce REST API, making it easy to retrieve, store, and manipulate data.

HTML5 is quickly emerging as dominant technology for developing cross-platform mobile applications. While developers can create sophisticated apps with HTML5 and JavaScript, some limitations remain, specifically: session management, access to the camera and address book, and the inability to distribute apps inside public App Stores. The Salesforce Mobile Container makes possible to combine the ease of web app development with power of the Android platform by wrapping a web app inside a thin native container, producing a hybrid application.

The Salesforce Mobile SDK provides PIN-based OAuth token encryption for Android devices that don't provide full storage encryption functionality. The SDK implementation is NOT designed to provide complete security. It's simply offered as an option for temporarily protecting your app from eavesdroppers. Please use caution in your production deployment with sensitive data. We strongly recommend deploying production apps on the latest generation of Android devices with build-in device encryption.

The following steps will help you get started with your development environment, whether you choose to develop native apps or hybrid apps. See the README files in the native/ and hybrid/ folders for additional notes pertaining to development in those environments.

1. Install the Android SDK (r23 or above) and Android Studio: http://developer.android.com/sdk/index.html
2. Get setup on github: http://help.github.com/

To pull down the SDK from github, create a new directory and git clone the salesforce SDK repo.

git clone https://github.com/forcedotcom/SalesforceMobileSDK-Android.git
