我的资产文件夹中都有所有音频，它们都是.ogg，由资产管理器加载，但有时我在Android上安装了apk，这会向我抛出错误消息：
E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 D / MediaPlayer：MediaPlayer中的setSubtitleAnchor D / MediaPlayer：MediaPlayer中的setSubtitleAnchor E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 D / MediaPlayer：MediaPlayer中的setSubtitleAnchor D / MediaPlayer：MediaPlayer中的setSubtitleAnchor E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 E / ExtMediaPlayer-JNI：env-> IsInstanceOf失败 E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0 D / MediaPlayer：MediaPlayer中的setSubtitleAnchor D / MediaPlayer：MediaPlayer中的setSubtitleAnchor I / QComExtractorFactory：嗅探：设置密钥以使用qti解析器 I / ExtendedExtractor：ExtendedExtractor :: create 0x0
当我退出一些auidios时，它已修复，但是当我再次安装apk时，它向我显示了另一个auidio的另一个异常，该异常在正确加载之前已出现，但现在由于此错误而失败。为什么？ 我试图解决将mp3文件转换为ogg文件的问题，并修复了一段时间的负载...但是当我用android studio重新安装apk时，其他音频文件在正确加载之前再次抛出异常，再次。而且这只发生在音频文件中，同一文件夹中的png图像加载得很好。 （我在资产文件夹中保存的每个音频都是相同的，有时一个音频不加载，有时另一个音频。）
我为音频收费的代码的一部分：
