编译Debug版本运行正常，但Release版本运行APP会崩溃。AS报错java.lang.UnsatisfiedLinkError: JNI_ERR returned from JNI_OnLoad in ‘/data/app/../lib/arm64/libxxx.so’
1 问题描述
本项目调用了IjkPlayer播放器，在Debug版本下APP运行正常，但如果编译运行Release版本，APP会崩溃。
2 问题分析
通过在 app/build.gradle 中的 BuildType 中开启Release版本的可调试功能（debuggable true），即可在IDE中输出APP运行日志。
Release版本奔溃日志如下：

本项目通过Implementation方式引入了IjkPlayer播放器，而IjkPlayer播放器的so库在编译完成后是放在 base.apk/lib/arm64-v8a 目录下的。
经过排查，该目录下存在libijksdl.so文件，但App运行时仍无法进行定位。
通过观察报错信息发现，APP资源路径是经过混淆了的，但是该ijkplayer库并未排除在混淆范围之外，故在加载so库时会无法识别混淆后的so库路径。
3 解决方法
此时修改proguard-rules.pro文件，将 tv.danmaku.ijk.media.player包及其子包均排除混淆范围：
