i see from log, sometimes Job string will return either "BAD,Please mine on the pool" or "BAD,Incorrect result".

so for workaround i add this check in MainActivity , before Job.split(",")
if (Job.contains("BAD")) break;

Thank you for logs, but unfortunately I have no intensions on continuing development of that miner in the nearest future.
