Batch
public final class Batch extends PendingResult
Handles a batch of PendingResult
items. Callbacks can be added and you can block to wait for all items in the batch to complete like any other PendingResult
item. A Batch can also be canceled if the results are no longer needed. In this case, the onBatchComplete
callback will never be triggered.
The results can be taken either from the underlying PendingResult
s or via take
but not both.

This reference will never be null so long as the GoogleApiClient is connected. It needs to be weak so that PendingResults don't pin disconnected GACs due to binder references to the PendingResults.
Public methods
await
public final R await ()
Blocks until the task is completed. This is not allowed on the UI thread. The returned result object can have an additional failure mode of INTERRUPTED
