A simple context monitoring framework to handle context sensing and polling of contextual information.
To monitor a particular context:
ContextManager mContextManager = new ContextManager(getApplicationContext());
//Specify the context along with the the after which you need an update for.
mContextManager.monitorContext(ContextManagerServices.CTX_FRAMEWORK_LOCATION, 60*60*1000L);
//Alternatively, Specify the context along with the the after which you need an update for, polling interval and flag.
mContextManager.monitorContext(ContextManagerServices.CTX_FRAMEWORK_LOCATION, 10*60*1000L, 30*60*1000L, null);
To receive updates about context:
mContextBroadCastReceiver = new ContextBroadCastReceiver();
IntentFilter filter = new IntentFilter(com.uob.contextframework.support.Constants.CONTEXT_CHANGE_NOTIFY);
filter.addCategory(Intent.CATEGORY_DEFAULT);
registerReceiver(mContextBroadCastReceiver, filter);
...
public class ContextBroadCastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String contentType = intent.getStringExtra(com.uob.contextframework.support.Constants.INTENT_TYPE);
if(contentType.equalsIgnoreCase(com.uob.contextframework.support.Constants.LOC_NOTIFY)){
//do something with the information.
...
}
}
}
To stop monitoring a particular context:
mContextManager.stopMonitoringContext(ContextManagerServices.CTX_FRAMEWORK_LOCATION);
- Monitor more contextual information (Application usage monitoring).
- Adaptive sensing
- Energy effective sensing (modify itself based on power levels)
