Android java.lang.UnsatisfiedLinkError-找不到“libffmpeg.so”

Question

我已经用eclipse https://github.com/youtube/yt-watchme构建了这个项目，它运行得很好，但是当我试图在android studio中构建这个项目时，我的Ffmpeg类出错了，我已经将我在eclipse中制作的运行演示中的所有文件复制到了我的android studio项目目录中，我将发布我的目录结构和build.gradle，请有人指导我吗？请参阅以下内容

和JNI函数中

Answer 1

是否为所有ABI添加了“libffmpeg.so”文件？('x86','x86_64','armeabi','armeabi-v7a','arm64-v8a','mips','mips64')如果没有，则仅为可用的ABI生成apk。假设为'armeabi'、'armeabi-v7a'abis拥有libffmpeg.so文件。然后您需要在app.gradle的android{}部分的ending中添加以下内容。

splits {

    // Configures multiple APKs based on ABI.
    abi {

        // Enables building multiple APKs per ABI.
        enable true

        // By default all ABIs are included, so use reset() and include to specify that we only
        // want APKs for x86, armeabi-v7a, and mips.

        // Resets the list of ABIs that Gradle should create APKs for to none.
        reset()

        // Specifies a list of ABIs that Gradle should create APKs for.


        include 'armeabi', 'armeabi-v7a'
        // Specifies that we do not want to also generate a universal APK that includes all ABIs.
        universalApk false
    }
}
