I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage).
So in the activity I use the following to attach the context:
intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName());
intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName());
intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext);
I register for the notifications in the activity:
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intents.ACTION_NOTIFICATION);
intentFilter.addCategory(Intents.CATEGORY_COMPLETION);
intentFilter.addCategory(Intents.CATEGORY_PROGRESSS);
Intent intent = registerReceiver(receiver, intentFilter);
In the background service I send notifications with the following code:
void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult)
{
Intent intent = new Intent(action);
intent.addCategory(category);
intent.setClassName(packageName, className);
if (extras != null) {
intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras);
}
intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult);
context.sendBroadcast(intent);
}
My problem is that the above broadcast will never be received. If however I comment out the line
intent.setClassName(packageName, className);
Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts.
Thanks,
Nic
