去opus官网下载opus-1.5.2.tar.gz，解压到Windows的F:\test目录下。

在解压后的opus-1.5.2目录中，新建一个Android.mk文件，内容如下：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

#我使用的是NDK 18

#NDK 17及以上不再支持ABIs [mips64, armeabi, mips]

APP_ABI := armeabi-v7a arm64-v8a x86 x86_64

APP_CPPFLAGS += -std=c++11

APP_STL := gnustl_shared

APP_PLATFORM := android-16

include $(LOCAL_PATH)/celt_sources.mk

include $(LOCAL_PATH)/silk_sources.mk

include $(LOCAL_PATH)/opus_sources.mk

LOCAL_MODULE        := opus

# Fixed point sources

SILK_SOURCES        += $(SILK_SOURCES_FIXED)

# ARM build

CELT_SOURCES        += $(CELT_SOURCES_ARM)

SILK_SOURCES        += $(SILK_SOURCES_ARM)

LOCAL_SRC_FILES     := \

    $(CELT_SOURCES) $(SILK_SOURCES) $(OPUS_SOURCES) $(OPUS_SOURCES_FLOAT)

LOCAL_LDLIBS        := -lm -llog

LOCAL_C_INCLUDES    := \

    $(LOCAL_PATH)/include \

    $(LOCAL_PATH)/silk \

    $(LOCAL_PATH)/silk/fixed \

    $(LOCAL_PATH)/celt

LOCAL_CFLAGS        := -DNULL=0 -DSOCKLEN_T=socklen_t -DLOCALE_NOT_USED -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64

LOCAL_CFLAGS        += -Drestrict='' -D__EMX__ -DOPUS_BUILD -DFIXED_POINT -DUSE_ALLOCA -DHAVE_LRINT -DHAVE_LRINTF -O3 -fno-math-errno

LOCAL_CPPFLAGS      := -DBSD=1 

LOCAL_CPPFLAGS      += -ffast-math -O3 -funroll-loops

include $(BUILD_SHARED_LIBRARY)

打开cmd命令行，执行下面三条命令。

F:

cd F:\test\opus-1.5.2

F:\test\Sdk\ndk\21.0.6113669\ndk-build APP_BUILD_SCRIPT=Android.mk NDK_PROJECT_PATH=.

最后成功在F:\test\opus-1.5.2\libs下得到四个平台的libopus.so库文件。

然后在Android Studio工程的CMakeLists.txt里面添加：

set(OPUS_DIR F:\\test\\opus-1.5.2)

include_directories(${OPUS_DIR}/include)

add_library(opus SHARED IMPORTED)

set_target_properties(opus PROPERTIES IMPORTED_LOCATION ${OPUS_DIR}/libs/${ANDROID_ABI}/libopus.so)

找到原有的target_link_libraries，在其括号中添加opus，例如：

target_link_libraries(native-lib ${log-lib} oboe opus)

然后就可以在native-lib.cpp中#include <opus.h>，然后使用opus_decoder_create和opus_decoder_destroy函数了。

解决办法：

把F:\test\opus-1.5.2\libs文件夹复制到F:\Projects\AndroidStudioProjects\MyApplication4\app\src\main，然后改名jniLibs（必须改成这个名称）。

CMakeLists.txt里面改下libopus.so库的路径。

set_target_properties(opus PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}/libopus.so)。
