It is because "LastLocationFinder" uses Activity's context and 
"singleUpdateReceiver" may outlive the activity, you can use "this.context = 
context.getApplicationContext();" in the constructor, but still 
"locationListener" holds the reference to the old activity, requesting single 
update in LastLocationFinder is broken, you may instead try to send broadcast 
to passive receiver
