This set of APIs provides a suite of tools for reading, storing and manipulating sensor descriptions and data. The tools provide descriptions and data in high-level standardized formats such as OGC SWE SensorML and OGC Observations and Measurements, which can be used in a variety of applications.

2. Mobile Sensor Actuator Gateway
Use the Android SDK to develop applications using the on-
board sensors of your mobile phone
Easy to use API for retrieving the descriptions and data of
the on-board sensors in standardized formats
Mobile Sensor Actuator Gateway uses OGC SWE SensorML
for descriptions and OGC Observations & Measurements
for data

3. Why Mobile Sensor Actuator
Gateway?
Devices like mobiles are used everywhere and many now
are instrumented with a variety of sensors & actuators
Low-level Android APIs do not provide sensor information
in a high-level, industry standard format
Mobile Sensor Actuator Gateway (MSAG) provides simple
APIs that are lightweight and straightforward for
developers to use
MSAG from Ericsson Labs is a sensor & actuator API
tailored for rapid prototyping of sensor applications

4. Main Features of MSAG
API provides two main calls:
– Get sensor descriptions in OGC SWE SensorML format
– Get sensor data in OGC Observations & Measurement
format
MSAG supports the following on-board sensors:
– Temperature
– Orientation
– Magnetic field
– Accelerometer
API also contains a cache for storage of historical data
All sensor readings are geotagged & timestamped

5. MSAG SDK examples
Use the sensor descriptions and data from the phone to render
sensor information on a map (see Ericsson Mobile Maps)

6. MSAG overview
AIDL Interface: Android IPC system
ServiceConnection: provides IPC interface
Auto-generated stub: provides application API

7. MSAG Client API
Library that is easily included in your Android mobile application
Supports Android phones with version 1.5 and later
Example code below shows getDesc() and getData() methods
public void getOperationCode() throws RemoteException {
/** Code for showing data on screen */
if( op_code == SHOW_DESC ){
checkCallingPermission( "ericsson.msag.Communicator" );
/** One of the methods of the Communicator interface */
res = communicator.getDesc();
/** Unbind service and disconnect */
unbindService( conn );
}else if( op_code == SHOW_DATA ) {
checkCallingPermission( "ericsson.msag.Communicator" );
/** Another method of the Communicator interface */
res = communicator.getData();
/** Unbind service and disconnect */
unbindService( conn );
}else {
res = null;
}
}
