Google Cloud Endpoints return value from a method

Question

How can I return a value (i.e. boolean, string, etc.) from either an @endpoint.method or a @MyModel.method (EndpointsModel)?

Answer 1

As per the documentation, you cannot write simple types like String, int, etc. The return types will need to be a POJO, an array or a Collection.
