Android集成bilibili播放器以及弹幕

考虑到开发直播和视频播放的必要性，网上了解到b站开源播放器(https://github.com/bilibili/ijkplayer)好用，集成下试试。
运行后发现b站原生的只能播放没有其他选项，考虑到方便性，采用这个方案:

https://github.com/CarGuo/GSYVideoPlayer

步骤
1.gradle集成(JCenter什么的别忘了)

    //ijkplayer的封装
    implementation 'com.shuyu:gsyVideoPlayer-java:6.0.3'
    //是否需要ExoPlayer模式
    implementation 'com.shuyu:GSYVideoPlayer-exo2:6.0.3'
    //根据你的需求ijk模式的so
    implementation 'com.shuyu:gsyVideoPlayer-armv5:6.0.3'
    implementation 'com.shuyu:gsyVideoPlayer-armv7a:6.0.3'
    implementation 'com.shuyu:gsyVideoPlayer-arm64:6.0.3'
    implementation 'com.shuyu:gsyVideoPlayer-x64:6.0.3'
    implementation 'com.shuyu:gsyVideoPlayer-x86:6.0.3'
    //弹幕
    implementation  'com.github.ctiao:DanmakuFlameMaster:0.9.16'
    compile 'com.github.ctiao:ndkbitmap-armv7a:0.9.21'
    compile 'com.github.ctiao:ndkbitmap-armv5:0.9.21'
    compile 'com.github.ctiao:ndkbitmap-x86:0.9.21'
