SDCF is an extensible and highly configurable sensor data collection framework for Android. The SDCF library provides a full configurable service to collect different sensor data (accelerometer, gsm, wifi, network and gps, light, temperature etc.) on a mobile android device. The data is stored in a local database (on the device) and can be transmitted to a remote host periodically (serialized to XML, and optionally packed into an rsa-encrypted archive). The service can also broadcast the collected sensor data in order to provide it to other applications.
