What exactly are you doing after channel.connect()?
Do you have any try/catch, read-write loops, and such?
Can you post the rest of the code until channel.disconnect()?

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM

apps on BYO-devices by containerizing them, leaving personal data untouched!
