Android java.lang.UnsatisfiedLinkError - 找不到 "libffmpeg.so"

Question

我已经用 eclipse 构建了这个项目 https://github.com/youtube/yt-watchme它运行良好，但是当我尝试在 android studio 中构建这个项目时，我的 Ffmpeg 类出现错误，我已将我在 eclipse 中制作的运行演示中的所有文件复制到我的 android studio 项目目录，我将发布我的目录结构和 build.gradle ，请有人指导我吗？请看下面

在 JNI 函数中

Answer 1

是否为所有 abis 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 abis 生成 apk。假设有 libffmpeg.so 文件用于 'armeabi'、'armeabi-v7a' abis。然后你需要在 app.gradle 的 android {} 部分的结尾添加以下内容。

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
    }
}
