I am developing an application that makes about 215 requests to Bittrex through its api.

After a while the application crashes and this message appears:

B4X:

I guess the message ResponseError. Reason: java.net.SocketTimeoutException: timeout, Response: Indicates that some responses to requests for data did not arrive or arrived late, so the timeout is exceeded.

Although it reduced the number of requests, sometimes some request that does not get a response.

As some messages arrive late or never arrive, ¿how do I capture the problem and act according to the type of problem, without the application breaking down?

This is the problem.
Are you calling 215 request paralel?
Did you not close the files used/copied?

HARD to help without seeing what you have done and how.
