无法将 64 位库添加到我的应用程序，Play 商店拒绝它

Question

我有一个使用 FFmpeg 处理视频的应用。从现在开始，就有了 64 位原生库的新需求。我一直在尝试使用 64 位二进制文​​件编译我的应用程序，但没有成功。

• 我尝试导出静态编译的二进制文件，然后添加了一个库模块来编译它们（因为在构建 apk 或捆绑包时看到静态文件可能存在一些问题）。
• 我添加了 Android 建议的 abiFilters 代码，然后我尝试排除 x86 和 x86_64，因为在某处读取它们可能会导致问题，并且使用这些架构的设备数量低于 4%。通过从 abi 过滤器中排除（在应用程序和库模块中）来做到这一点。添加了拆分，包括用于 armeabi 32 和 64 的 abis，不包括用于 x86，并为应用程序和库中的每个 abi 设置唯一的版本代码（过滤器似乎无法正常工作*参见图片）。

这些都不起作用，当我探索我的 apk 添加 64 位资产但在 lib 下只出现 32 位（我相信这是 PlayStore 抱怨的原因）。 * 见附图

我真的不明白我错过了什么。这是我的 gradle 文件：FFmpegANdroid library gradle:

apply plugin: 'com.android.library'
//apply plugin: 'com.github.dcendents.android-maven'
apply plugin: "com.jfrog.bintray"

// This is the library version used when deploying the artifact

谁能帮我找出问题所在？我错过了什么？

** 我正在使用：

• Android Studio 3.5.1 稳定版
• gradle-5.4.1

Answer 1

您是否按照Android documentation 中的所有这些步骤操作？

你好吗build your application？

对于拆分问题，试试这个：

 splits {
      abi {
            reset()
            include "armeabi-v7a", "arm64-v8a"
          }
   }

Answer 2

你的 gradle 应该是这样的

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.qp.ffmpegdemo"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 2
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        ndk.abiFilters 'armeabi-v7a','arm64-v8a','x86','x86_64'
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.10.2"
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.1'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
    implementation project(path: ':FFmpegAndroid')
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

   implementation 'com.writingminds:FFmpegAndroid:0.3.2'

}

现在添加一些虚拟 c++ 代码，如下所示，因为 google 只需要 64 位架构的设备，它不在 FFmpgeg 中，所以我们只需添加简单的我们自己的库，这样就可以解决了。。。 p>

为此在您的主目录中创建 cpp 文件夹并将以下文件放入其中。

# 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)

# 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.cpp

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
             native-lib.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.cpp

                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib} )

并如下创建cpp文件

#include <jni.h>
#include <string>

extern "C" JNIEXPORT jstring JNICALL
Java_com_qp_ffmpegdemo_MainActivity_stringFromJNI(
        JNIEnv* env,
        jobject /* this */) {
    std::string hello = "Hello from C++";
    return env->NewStringUTF(hello.c_str());
}

然后生成签名的apk并尝试上传。
