Yes, with the marker set at 1000 I would now *sometimes* get the
onMarkerReached() callback, but extremely rarely (maybe once in a
hundred one-second 8-bit mono PCM sample playbacks on my ADP, which is
why I had not even noticed it at first). It may depend on parameter
settings, sample length, CPU load, whatever, but for my use it is
totally unreliable and useless. At least it proves that my coding was
not totally wrong, or else the callback would *never* have been
invoked. :-)
I think we need some feedback from the Android Team about how
onMarkerReached() is supposed to behave or under what conditions it
works. Some undocumented statement order that one has to adhere to?
Timing assumptions? By contrast, MediaPlayer's OnCompletionListener()
works just fine for me.
Thanks
