在进行视频工具开发的时候,遇到了下方的错误,这个问题网上的解决方式我都试过了,却不适用我。
网上的解释都是路径配错了,经仔细查看后,包括查看CMakeLists.txt文件,都没有发现什么异常。
项目文件包如下:
Cmake.txt配置如下:
# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html
# Sets the minimum version of CMake required to build the native library.
cmake_minimum_required(VERSION 3.4.1)
set(NATIVE_LIBS ${CMAKE_SOURCE_DIR}/libs)
add_library(mp4v2
SHARED
IMPORTED)
set_target_properties(mp4v2
PROPERTIES
IMPORTED_LOCATION
${NATIVE_LIBS}/${ANDROID_ABI}/libmp4v2.so)
include_directories(libs/include)
# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.
add_library( # Sets the name of the library.
native-lib
# Sets the library as a shared library.
SHARED
# Provides a relative path to your source file(s).
src/main/cpp/native-lib.cpp
src/main/cpp/MP4Encoder.cpp
src/main/cpp/MP4EncoderHelper.cpp)
# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.
find_library( # Sets the name of the path variable.
log-lib
# Specifies the name of the NDK library that
# you want CMake to locate.
log)
# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.
target_link_libraries( # Specifies the target library.
native-lib
mp4v2
# Links the target library to the log library
# included in the NDK.
${log-lib})
解决办法:
依据libs里面的so库添加ndk配置
ndk {
abiFilters "arm64-v8a","armeabi-v7a","x86","x86_64"
}
android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
applicationId "com.ttxs.mp4tracfator"
minSdkVersion 18
targetSdkVersion 28
versionCode 1
versionName "1.0"
externalNativeBuild {
cmake {
cppFlags "-std=c++11 -frtti -fexceptions"
}
}
ndk {
abiFilters "arm64-v8a","armeabi-v7a","x86","x86_64"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
main {
jniLibs.srcDir 'libs'
}
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
}
