I thought that Action was preeminent during intent resolution and if
the intent had the same action as the intent filter, it would be
considered a match regardless of data, if the filter did not specify
anything.
So I was very surprised to find that supplying action+data where
filter had only action, causes it to fail.
In the code below, if you comment out line 47 so that data is *not*
sent, only then it resolves correctly.
alertIntent.setData(alert_i);
To get it to work with the data (an id that is simply a String), what
mime type should I specify in the intent filter?
thanks...
