Answer 1

Based on the error stack, I think that this is the same problem as Android http connection exception and Error StrictMode$AndroidBlockGuardPolicy.onNetwork
Where in the device is throwing an exception whilst checking for StrictMode$AndroidBlockGuardPolicy
This appears to prevent your app from performing long running blocking operations in the main thread which would cause the device UI to hang.
Work arounds can be found in the provided links to prior questions. Though I think you should be spawning a thread to perform the operation, rather than overriding the strict mode policy.
