Android :: Sending / Receiving Custom Broadcast Intent

I'm building a service that sends a broadcast intent when some value changes. The service sends the broadcast like this:

Intent broadcastIntent = new Intent(); broadcastIntent.setAction("nl.vu.contextframework.NEWREADING"); broadcastIntent.setData(Uri.parse("context://"+cer.getKey())); broadcastIntent.putExtra("reading",cer); broadcastIntent.addCategory("nl.vu.contextframework.CONTEXT"); sendBroadcast(broadcastIntent);

In some Activity (in a different process), I'm tryint to receive this broadcast as follows:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addDataScheme("context");
intentFilter.addCategory(CATEGORY_CONTEXT);
registerReceiver(new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Log.d(TAG,"Received intent "+intent); }
}, intentFilter);
