Media Player setDataSource

Question

The function setDataSource() works with a url, but I need you to get a file from my raw (for example).

I used:

Uri url = Uri.parse("android.resource://" + ctx.getPackageName() + "/" + R.raw.file);
mediaPlayer.setDataSource(url.toString());

But it doesn’t work.

Answer 1

The method setDataSource() has several overloads, the one you are trying to use gets a path.
The method toString() class Uri does not return a path but rather the representation, in string, of Uri with which it was built.

What you’re doing is the equivalent of this:

mediaPlayer.setDataSource("android.resource://" + ctx.getPackageName() + "/" + R.raw.file);

You’re not actually using Uri who built on the line:

Uri url = Uri.parse("android.resource://" + ctx.getPackageName() + "/" + R.raw.file);

You should therefore use the Overload of the method setDataSource() who receives a Uri:

Uri url = Uri.parse("android.resource://" + ctx.getPackageName() + "/" + R.raw.file);
mediaPlayer.setDataSource(ctx, url);

Answer 2

Works if it is a local file, but it is a streaming file (a url)

AssetFileDescriptor afd = ctx.getAssets().openFd("file.txt");
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());

where file.txt has the url for example, it does not work.

Answer 3

I have a file - file.m3u8 with the following content:

EXTM3U  
    EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="bipbop_audio",LANGUAGE="eng",NAME="BipBop Audio 1",AUTOSELECT=YES,DEFAULT=YES
    EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="bipbop_audio",LANGUAGE="eng",NAME="BipBop Audio 2",AUTOSELECT=NO,DEFAULT=NO,URI="alternate_audio_aac_sinewave/prog_index.m3u8"

That file plays a video if it’s on a server.

I plan to have that file inside my apk and play the file using Media Player with setDataSource("file.m3u8")
