There is an example 'plugin' that demonstrates how to use the plugin interface in Torque here: [[1]] - this is a basic example, have a look at the AIDL file for the API documentation

There is a forum post here: [[2]] that explains some more about plugin development

Torque also responds to intents - you can send or listen to the following intents:

org.prowl.torque.REQUEST_TORQUE_QUIT    (Properly shuts down Torque and related services)

org.prowl.torque.OBD_CONNECTED          (Sent when Torque connects to an OBD2 adapter)
org.prowl.torque.OBD_DISCONNECTED       (Sent when Torque is disconnected from the OBD2 adapter)
org.prowl.torque.APP_LAUNCHED           (Sent when Torque starts up)
org.prowl.torque.APP_QUITTING           (Sent when Torque is about to quit)

Here is a list of some of the extended information Torque provides which your plugin can call on, or you can use for custom themes - a full list of what torque supports for your vehicle can be viewed using the TorqueScan plugin:

Identifier Description
0x03 Fuel system status
0x04 Calculated engine load value
0x05 Engine coolant temperature
0x06 Short term fuel trim (bank 1)
0x07 Long term fuel trim (bank 1)
0x08 Short term fuel trim (bank 2)
