From 721ea491a8e3e9ea5a130965dc5761fc335c3e61 Mon Sep 17 00:00:00 2001 From: Jeff Davidson Date: Tue, 22 Apr 2014 23:25:53 -0700 Subject: Support generation of Parcelable nano messages. This CL adds the "parcelable_messages" option. When enabled, all generated message classes will conform to the Android Parcelable contract. This is achieved by introducing a new parent class for generated classes which implements the required functionality. Since the store_unknown_fields option also makes use of a superclass, ExtendableMessageNano, we have two versions of the new Parcelable superclass: one extending MessageNano, and one extending ExtendableMessageNano. These classes are otherwise identical. As these classes depend on Android framework jars, they are not included in the host .jar build of the nanoproto library. Finally, add a test suite for running tests of Android-specific functionality, as this cannot be done on a desktop JVM.
