我在 ndk 构建过程中遇到错误。我的项目中只有一个 android.mk 文件和一个 Application.mk 文件 AndroidNDK：尝试在/home/parag.j/AndroidArm//jni/Android.mk 中定义本地模块 'protobuf'。
Android NDK：但是这个模块已经由/home/parag.j/AndroidArm//jni/Android.mk 定义。

这是我 Android.mk 文件

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE=ndktest
LOCAL_SRC_FILES=ndktest.cpp
include $(CLEAR_VARS)
LOCAL_MODULE := c++_shared
LOCAL_SRC_FILES := $(LOCAL_PATH)/inc/build/libc++_shared.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := armnn
LOCAL_SRC_FILES := $(LOCAL_PATH)/inc/build/libarmnn.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := armnnTfParser
LOCAL_SRC_FILES := $(LOCAL_PATH)/inc/build/libarmnnTfParser.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := protobuf
LOCAL_SRC_FILES := $(LOCAL_PATH)/inc/build/libprotobuf.so
include $(PREBUILT_SHARED_LIBRARY)
LOCAL_LDLIBS    += -lm -llog -landroid
LOCAL_CFLAGS += -DARM_NEON_64BIT -O3 -mfpu=neon -mcpu=kryo -std=c++14 -pie
LOCAL_SHARED_LIBRARIES := opencv_java3 armnn armnnTfParser protobuf c++_shared
LOCAL_C_INCLUDES  :=   $(LOCAL_PATH)/inc/include
include $(BUILD_SHARED_LIBRARY)

这是我 Application.mk 文件

APP_ABI:=arm64-v8a 
APP_CFLAGS += -Ofast
APP_OPTIM := release
APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_PLATFORM := android-22
ANDROID_TOOLCHAIN_NAME := clang++

您忘记为makefile的最后一部分(重新(设置LOCAL_MODULE。我认为最后几行应该是：

LOCAL_MODULE=ndktest
LOCAL_SRC_FILES=ndktest.cpp
LOCAL_LDLIBS    += -lm -llog -landroid
LOCAL_CFLAGS += -DARM_NEON_64BIT -O3 -mfpu=neon -mcpu=kryo -std=c++14 -pie
LOCAL_SHARED_LIBRARIES := opencv_java3 armnn armnnTfParser protobuf c++_shared
LOCAL_C_INCLUDES  :=   $(LOCAL_PATH)/inc/include
include $(BUILD_SHARED_LIBRARY)

(当然，去掉文件开头的ndktest行(
