I tried call the protobuf as an Android module, first I configure the variable NDK_MODULE_PATH with the modules project folder and in the Android.mk I call $(call import-module, protobuf) like that:
LOCAL_PATH := $(call my-dir)
$(call import-module, protobuf)
include $(CLEAR_VARS)
#...
But it gives me an error:
Android NDK: Trying to define local module 'protobuf-cpp-lite' in /home/alex/Projects/network-simulator/3rd-party/protobuf/Android.mk.
Android NDK: But this module was already defined by /home/alex/Projects/network-simulator/3rd-party/protobuf/Android.mk.
/opt/android-ndk-r10/build/core/build-module.mk:34: *** Android NDK: Aborting. . Stop.
When I tried to build protobuf separately in its folder I got the same error.
