StrictMode DiskReadViolation

[prashanOS]

Looks like the Iterable SDK is reading/writing to disk from the current thread instead of delegating to an IO thread.

Note this is just one example - would recommend doing an audit of the SDK of all locations where you read/write to disk to ensure the exposed methods are main-safe.

java.lang.RuntimeException: StrictMode ThreadPolicy violation
... (removed for brevity)
Caused by: android.os.strictmode.DiskReadViolation

Would highly recommend setting up StrictMode in your sample apps in CI so that you can catch these issues!
