Freeze application DeviceMonitor start

[Alephgsm]

hi
i have a problem in this library
we run DeviceMonitor after start application
if Connected device status is "Allow USB debugging?" The software become To freeze(hangs)
in this case if we accept Computer fingerprint The software does not go out of Freeze mode.
just need to close the software (There is no other way)
And next time, Before attempting to start DeviceMonitor, we must accept the computer rsa key fingerprint on the device
Then start DeviceMonitor
i know DeviceMonitor reports events related to connect and their status,I think in "Allow USB debugging mode?" Fails to get the status and freezes the application!
Model Test i9300i, j600g
Is there a solution to this problem?
