Question

我最近将应用音频文件资源切换为扩展文件。问题是，当我使用APEZProvider读取音频文件时，应用程序不会播放任何内容。

请参阅Exoplayer错误：

E/ExoPlayerImplInternal: Source error.
                     com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor) could read the stream.

E/MMParserExtractor: FileSource::FILE_SOURCE_DATA_EN

我的自定义APEZProvider：

public class ZipFileContentProvider extends APEZProvider {
String AUTHORITY = "sample.sample";

@Override
public String getAuthority() {
    return AUTHORITY;
}

public Uri readAudioFileFromObb(String filename){

    String path = "content://" + AUTHORITY + File.separator + filename;

    return Uri.parse(path);
}
}

我的AndroidManifest.xml

    <provider
        android:authorities="sample.sample"
        android:name=".PlaySong.ZipFileContentProvider"
        android:exported="true"
        android:multiprocess="true">
        <meta-data
            android:name="mainVersion"
            android:value="14"></meta-data>
    </provider>

Exoplayer版本='r2.2.0'

我怀疑您需要在getType()中覆盖APEZContentProvider方法以返回相应的音频类型。

无法在Android扩展文件OBB中播放Exoplayer中的OGG音频文件
