Open Locast Core Example

Open Locast Core is an Android library that works in conjunction with the Open Locast web platform. It is a framework for building location-based media apps, with the ability to synchronize data to/from the web platform.

This application is a fully-working example of using the Open Locast Core and is intended to be used alongside Open Locast Web.

Out of the box, Open Locast Core Example provides the ability to login to an Open Locast Web site.

Once logged in, the application can be used both online and offline, allowing content to be created, deleted, etc. on the device without a network connection. Changes will be synchronized with the server once a network connection has been restored.

Content in Open Locast Web / this application is broken up into Casts and Collections.

Casts

A cast is a geo-located collection of media which can contain one or more pictures/videos. You can imagine a cast as a single location, object, or event, perhaps with different viewpoints or angles.

Casts have a privacy restriction. They can be marked public, protected or private. Public casts can be edited by any user. Protected casts can only be edited by the original author, but seen by anyone. Private casts are only visible and editable by the original author.

Casts have titles, descriptions, and allow for free tagging.

Collections

A collection is a set of casts. They are intended to be highly generic, with a use defined by the user. They can have titles and descriptions and feature the same privacy restrictions as casts.

Building

This application depends on a number of libraries to function. Some are provided in the libs/ directory, but a number are provided as git submodules. You can check out the complete project using the following command:

git clone --recurse-submodules https://github.com/mitmel/Locast-Core-Android-Example.git

Please see the README of Open Locast Core for more details on how to build the library.

Server Communication

The application communicates with the server using a public RESTful API, allowing both authenticated and unauthenticated API requests.

The API's base URL is stored in your application's manifest. You can add it in by adding a block similar to this to your <application /> section of your AndroidManifest.xml:

    <meta-data
        android:name="edu.mit.mobile.android.locast.base_url"
        android:value="http://example.com/openlocast/api/" />

Please see Locast Web for more details on how to set up the server.
