ExoPlayer从原始文件夹中读取mp3文件 [英] ExoPlayer reading mp3 file from raw folder

问题描述

是否可以将应用程序原始文件夹中的mp3文件设置为ExoPlayer?

Is there any possibility to set an mp3 file that's located in the app's raw folder to ExoPlayer?

不幸的是，我尝试使用以下代码片段来实现它:

I tried to achieve it with the following code snippet without success unfortunately:

mMediaPath = "android.resource://" + getPackageName() + File.separator + R.raw.ringtone;

任何帮助将不胜感激！

推荐答案

可以从原始文件夹加载文件，关键是使用RawSourceDataSource.

It's possible to load files from the raw folder, the key is to use RawSourceDataSource.

这是一个示例(在Kotlin中)，用于在原始目录中为mp3文件创建LoopingMediaSource:

Here's an example(in Kotlin) to create a LoopingMediaSource for an mp3file in the raw directory:

val uri = RawResourceDataSource.buildRawResourceUri(R.raw.mp3file)
val dataSource = RawResourceDataSource(this)
dataSource.open(DataSpec(uri))

val source = ExtractorMediaSource(uri, DataSource.Factory { dataSource }, Mp3Extractor.FACTORY, null, null)

LoopingMediaSource(source)
