From d6592c758c2574ccdca78fdb70a2edc314447269 Mon Sep 17 00:00:00 2001 From: Ulas Kirazci Date: Thu, 14 Mar 2013 16:44:33 -0700 Subject: [PATCH] Nano protobufs. Like micro protobufs except: - No setter/getter/hazzer functions. - Has state is not available. Outputs all fields != their default. - CodedInputStream can only take byte[] (not InputStream). - Repeated fields are in arrays, not ArrayList or Vector. - Unset messages/groups are null, not "defaultInstance()". - Required fields are always serialized. To use: - Link libprotobuf-java-2.3.0-nano runtime. - Use LOCAL_PROTOC_OPTIMIZE_TYPE := nano Change-Id: I7429015b3c5f7f38b7be01eb2d4927f7a9999c80 --- Android.mk | 32 + java/README.txt | 51 +
