I got a TransactionTooLargeException. Not reproducible. In the docs it says
The Binder transaction failed because it was too large.
D
So for us it was we were trying to send too large of an object through our AIDL interface to a remote service. The transaction size cannot exceed 1MB. The request is broken down into separate chunks of 512KB and sent one at a time through the interface. A brutal solution I know but hey - its Android :(
