// Create dynamic schema
DynamicSchema.Builder schemaBuilder = DynamicSchema.newBuilder();
schemaBuilder.setName("PersonSchemaDynamic.proto");
MessageDefinition msgDef = MessageDefinition.newBuilder("Person") // message Person
.addField("required", "int32", "id", 1) // required int32 id = 1
.addField("required", "string", "name", 2) // required string name = 2
.addField("optional", "string", "email", 3) // optional string email = 3
.build();
schemaBuilder.addMessageDefinition(msgDef);
DynamicSchema schema = schemaBuilder.build();
// Create dynamic message from schema
DynamicMessage.Builder msgBuilder = schema.newMessageBuilder("Person");
Descriptor msgDesc = msgBuilder.getDescriptorForType();
DynamicMessage msg = msgBuilder
.setField(msgDesc.findFieldByName("id"), 1)
.setField(msgDesc.findFieldByName("name"), "Alan Turing")
.setField(msgDesc.findFieldByName("email"), "[email protected]")
