android - Are separate intent services queued on the same thread? -
i have 2 intent services - intentservicea
, intentserviceb
they have following class definitions:
public class firstservice extends intentservice { public firstservice() { super("first_service"); } @override protected void onhandleintent(intent intent) { log.d("chi6rag", "first starts"); (long = 0l; < 10000000l; i++) { if (i == 0l) log.d("chi6rag", "first started"); } log.d("chi6rag", "first ends"); } }
and
public class secondservice extends intentservice { public secondservice() { super("second_service"); } @override protected void onhandleintent(intent intent) { log.d("chi6rag", "second starts"); (long = 0l; < 10000000l; i++) { if (i == 0l) log.d("chi6rag", "second started"); } log.d("chi6rag", "second ends"); } }
if execute following code in activity:
startservice(new intent(this, intentservicea.class));
startservice(new intent(this, intentserviceb.class));
i see following printed in logs:
d/chi6rag (11734): first starts
d/chi6rag (11734): first started
d/chi6rag (11734): second starts
d/chi6rag (11734): second started
d/chi6rag (11734): first ends
d/chi6rag (11734): second ends
while if 1 sees intent service docs, mentions passes one intent @ time
onhandleintent
method of intentservice
question: there separate worker thread each , every intent service? because expected logs are:
d/chi6rag (11734): first starts
d/chi6rag (11734): first started
d/chi6rag (11734): first ends
d/chi6rag (11734): second starts
d/chi6rag (11734): second started
d/chi6rag (11734): second ends
the intentservice following:
- creates default worker thread executes intents delivered onstartcommand() separate application's main thread.
- creates work queue passes 1 intent @ time onhandleintent() implementation, never have worry about
multi-threading- provides default implementation of onstartcommand() sends intent work queue , onhandleintent() implementation.
since have multiple classes extended form intentservice each has own specific onhandleintent. these handled on separate work queues.
