二、解决方案

上述报错提示无法找到 libijkffmpeg.so 动态库 , 先检查下 apk 打包时 , 是否有上述动态库 ;

最后发现 , 在打包出来的 apk 文件中 ,

lib/armeabi-v7a 中存在 libijkffmpeg.so 动态库 ,

但是在 lib/arm64-v8a 中不存在 libijkffmpeg.so 动态库 ,

手机设备是 64 位的 , 自然加载 lib/arm64-v8a 中的动态库 , 因此报上述错误 ;

在 build.gradle 中的 dependencies 依赖中 , 添加

implementation 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'

依赖 , 即可将 64 位的 libijkffmpeg.so 动态库编译到应用中 ;

dependencies {
    implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'
    implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'
    implementation 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'
    implementation 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'
}
