I would still guess that something is wrong with the build setup, but I'm not familiar enough with AOSP to say what the problem is. If you need to work with AOSP then I would recommend making sure you build your protos the exact same way AOSP builds its own protos. For example, make sure to use AOSP's protoc (I guess they call their version aprotoc?) and link against AOSP's protobuf libraries. If you use the protoc and protobuf libraries installed on your system then they might be a completely different version from what AOSP needs to use.
