由日志 1，那么获取到解体安装包和失常安装包，提取 com.bykv.vk.component.ttvideo.player.TTPlayer 类下的 Native 代码进一步剖析
解体包： TTPlayer 类 Native 办法申明
private final native long _create(Context context, int i, String str); public static final native int _getCurrentPosition(long j); public static final native int _getDuration(long j); public static final native float _getFloatValue(long j, int i, float f); public static final native int _getIntValue(long j, int i, int i2); public static final native long _getLongValue(long j, int i, long j2); public static final native String _getStringValue(long j, int i); public static final native int _getVideoHeight(long j); public static final native int _getVideoWidth(long j); public static final native int _isLooping(long j); public static final native int _isPlaying(long j); public static final native int _pause(long j); public static final native int _prepare(long j); public static final native void _release(long j); public static final native int _reset(long j); public static final native int _seek(long j, int i); public static final native void _setCacheFile(long j, String str, int i); public static final native void _setDataSource(long j, String str); public static final native void _setDataSourceFd(long j, int i); public static final native int _setFloatValue(long j, int i, float f); public static final native int _setIntValue(long j, int i, int i2); public static final native int _setLongValue(long j, int i, long j2); public static final native void _setLooping(long j, int i); public static final native int _setStringValue(long j, int i, String str); public static final native void _setSupprotSampleRates(int[] iArr, int i); public static final native int _setVideoSurface(long j, Surface surface); public static final native void _setVolume(long j, float f, float f2); public static final native int _start(long j); public static final native void _stop(long j);失常包： TTPlayer 类 Native 办法申明
public static final native void _close(long j); private final native long _create(Context context, int i, String str); public static final native String _getAppPath(); public static final native int _getCurrentPosition(long j); public static final native double _getDoubleValue(long j, int i, double d); public static final native int _getDuration(long j); public static final native float _getFloatValue(long j, int i, float f); public static final native int _getIntValue(long j, int i, int i2); public static final native Object _getJObjectValue(long j, int i); public static final native long _getLongValue(long j, int i, long j2); public static final native String _getStringValue(long j, int i); public static final native int _getVideoHeight(long j); public static final native int _getVideoWidth(long j); public static final native int _isLooping(long j); public static final native int _isPlaying(long j); public static final native void _mouseEvent(long j, int i, int i2, int i3); public static final native int _pause(long j); public static final native int _prepare(long j); public static final native void _prevClose(long j); public static final native void _registerPlayerInfo(); public static final native void _release(long j); public static final native int _reset(long j); public static final native void _rotateCamera(long j, float f, float f2); public static final native int _seek(long j, int i); public static final native void _setAudioProcessor(long j, AudioProcessor audioProcessor); public static final native void _setCacheFile(long j, String str, int i); public static final native void _setDataSource(long j, IMediaDataSource iMediaDataSource); public static final native void _setDataSource(long j, String str); public static final native void _setDataSourceFd(long j, int i); public static final native int _setDoubleValue(long j, int i, double d); public static final native int _setFloatValue(long j, int i, float f); public static final native int _setIntValue(long j, int i, int i2); public static final native void _setLoadControl(long j, LoadControl loadControl); public static final native int _setLongValue(long j, int i, long j2); public static final native void _setLooping(long j, int i); public static final native void _setMaskInfo(long j, MaskInfo maskInfo); public static final native void _setMediaTransport(long j, MediaTransport mediaTransport); public static final native int _setStringValue(long j, int i, String str); public static final native void _setSubInfo(long j, SubInfo subInfo); public static final native void _setSupportFormatNB(int i); public static final native void _setSupprotSampleRates(int[] iArr, int i); public static final native int _setSurfaceValue(long j, long j2); public static final native int _setVideoSurface(long j, Surface surface); public static final native void _setVolume(long j, float f, float f2); public static final native int _start(long j); public static final native void _stop(long j); public static final native void _switchStream(long j, int i, int i2); public static final native void _takeScreenshot(long j);下面两个都是该类下所有的
native 办法，肉眼可见解体包的 native 代码显著比失常包的少；上文日志 1 中提到
Failed to register native method com.bykv.vk.component.ttvideo.player.TTPlayer._close(J)V；查看解体包的 native 办法，果然没有此办法
public static final native void _close(long j);；
前提是： 1、应用同一个工程打包 2、以上代码所依赖的是同一个版本的穿山甲广告 SDK 3、其中有一个模块版本不一样（作者本人的一个 library） 4、打的是 release 包
猜测： 如果是同一个版本的同一份代码，是否有可能是因为混同规定不同，或者抵触导致无用代码被移除，最终造成 native 办法注册失败呈现的解体？
那么接下来去看看打包输入的混同相干文件如何：
mapping.txt：源代码混同的映射表 seeds.txt：未被混同的类和成员 dump.txt：所有代码被解决后的残缺列表 usage.txt：被优化移除、删除的代码 【本文咱们重点关注这个】
3、混同剖析
咱们针对 com.bykv.vk.component.ttvideo.player.TTPlayer._close(J)V native 办法进行剖析！！！
办法原型是：public static final native void _close(long j);
解体包
mapping.txt
没有发现 \_close(long j) 办法被混同
seeds.txt
没有发现 \_close(long j) 办法被保留
usage.txt
发现 \_close(long j) 办法被移除除此之外，咱们还发现其余的 native 办法也被移除了！！！ （下面有提到解体包的 native 办法比失常包的要少）
失常包
mapping.txt
没有发现 \_close(long j) 办法被混同
seeds.txt
发现 \_close(long j) 办法被保留usage.txt
没有发现 \_close(long j) 办法被移除
显著了，剖析到这里看到了两个包混同之间的差异：大胆猜想是 native 办法没有找到，引起注册失败，导致解体。
有一点总结：native 办法不能被混同、移除。
4、最初
那么，在我的我的项目中如何解决就比较清楚了，增加混同规定，不移除、不会混同该 native 办法即可。
