Sana Mobile Client

Overview

The new client code is intended to be a self-contained, modularized, project including all necessary support libraries and unit testing code.

Development Requirements

1. Android Studio Additional prerequisites are required for installing Android Studio. Please see the System Requirements for Android Studio for your platform.
2. The Android support libraries available for installation through the SDK manager.
3. Emulator or Hardware device connected via USB with API level 8 or higher.

Notes

1. If you do not have a hardware device available, additional instructions for creating an emulator are available on the Android Developer Site’s Managing Virtual Devices page.
2. If your workstation includes an Intel processor with hardware virtualization support and you are developing on Windows, you will find the emulator runs significantly faster if you also install the Intel Hardware Accelerated Execution Manager available through the SDK manager.

Source Code

Source code for the Android based mobile client is available by cloning the sana.mobile repository.

git clone https://github.com/SanaMobile/sana.mobile.git

We highly recommend creating a Github account and forking the repository in lieu of directly cloning the repository so that any changes that you may make may be more easily contributed to the platform later via a pull request.

Import, Build, and Run instructions

The recommended method for building the code is to use Android Studio. The following steps should allow you to obtain, build, and run the code with minimal difficulty.

1. Open Android studio.
2. Import project from Version control.
3. Enter either the url for the official Sana repository listed above or a fork under
4. your own account if you created one.
5. Select the defaults presented on the import page.
6. When the gradle project has finished importing and building, select the app module and press run. When the app starts you will be presented with an authentication screen. The resources in the source code includes a flag that loads a set of default credentials which will successfully authenticate against a Sana demo server.

For additional details on working with Android Studio, including testing and debugging, please consult the Workflow page on the Android Developer site.

Code Structure

The gradle based project is split into three distinct modules.

1. api – A pure java library that includes the POJO’s, network functions, and utilities for processing data.
2. api-android – Android implementation and wrappers around the pure Java api.
3. app – The code and resources for the Android based application.

The motivation for splitting the project into the three discrete modules was to allow developers who may be interested wished to implement an alternate frontend, develop a client on another platform, or otherwise may find some portion of the libraries useful to do so more easily. The following sections contain additional details and features of each project that should assist developers working with the code.

api Module

The api module provides a pure Java library that contains the POJO’s that correlate with the data model used by the client, basic network code for communicating with the Sana middleware, and a number of utility functions.

api-android Module

The api-android module contains source code for non-application classes and interface to work with the Sana mobile code including communication with MDS.

app Module

The app module contains the source code for the front end visual components and classes specific to the application.
