You should rather check if the copy() was processing some data.

You can also ask the source (url) if there is some data available, but you might need to add some small delay to make sure that some data is made available....

The URLStream also provides the info about the contentLength and total read...

Thank you. What is the detailed procedure

One more question, how to stop playing

[pschatzmann]

You just stop calling coper.copy() or you can call copier.setActive(false) to temporarily halting the processing..
Maybe url.end() might also work, since closing the source stops providing data...

Stoping everything properly is calling end() on all objects whch will release the resources....
