Batch requests throws 404 not found

问题:

I'm using the Google Apps Java client library to develop an Android application. I am trying to send a batch request as explained here.

This is my request code for the discovery endpoint, which you can see has a batchPath field with "batch" as value:

BatchRequest batchRequest = mApi.batch(); 

mApi.insert(mEntity).queue(batchRequest, callback); 

batchRequest.execute();

However I keep getting a 404 error. I have already deployed my rebuilt project and double checked the API url. Why is my request not reaching my generated endpoint?

Unfortunately, Cloud Endpoints doesn't support REST batching (which the Java client library is trying to use). One can use JSON-RPC for batching, but most client libraries are REST-based, rather than RPC-based.
