Setting Data Source To An Raw Id In Mediaplayer

In MediaPlayer.create method an id to a Raw file can be used but how to use that in setDataSource method?

Solution 1:

Refer to the source android.media.MediaPlayer

AssetFileDescriptorafd= context.getResources().openRawResourceFd(resid);
if (afd == null) return;
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();

You may want to add try-catch to the block.

Solution 2:

paraphrasing @Kartik's answer here Get URI of .mp3 file stored in res/raw folder in android

If you want to get any resource URI then there are two ways :

1. Using Resource Name

Syntax : android.resource://[package]/[res type]/[res name]

Example : Uri.parse("android.resource://com.my.package/drawable/icon");

2. Using Resource Id

Syntax : android.resource://[package]/[resource_id]

Example : Uri.parse("android.resource://com.my.package/" + R.drawable.icon);

These were the examples to get the URI of any image file stored in drawable folder. Similarly you can get URIs of res/raw folder.

IMO the second way would be preferred as renaming the resource etc can be easily refactored.

Set the data source like so:

CONSTANTS.RES_PREFIX = "android.resource://com.my.package/"

mp.setDataSource(getApplicationContext(),
              Uri.parse(CONSTANTS.RES_PREFIX + R.raw.id));

Solution 3:

You can load the raw audio into an input stream and load it into a MediaPlayer as you would a normal stream:

InputStreamins= getResources().openRawResource(R.raw.example);

and then follow a streaming tutorial like pocketjourney

But this is overly complicated as you can just call

mp = MediaPlayer.create(counterstrikesb.this, R.raw.example);
