Right place for putting mp3 files in an android project

The best place to put such .mp3 or any other files would be in the assets folder.

These files once stored will become a part of your android app itself and can be read easily. This tutorial describes it well.

 AssetFileDescriptor afd = getAssets().openFd("AudioFile.mp3");
 MediaPlayer player = new MediaPlayer();
 player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
 player.prepare();
 player.start();

Alternatively you can also store it in the raw folder and read it directly by specifying the path as the raw folder.
this can be played as:

int resID=getResources().getIdentifier(fname, "raw", getPackageName());
MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);

Here are some steps you can easily follow.

Step-1: Open the android studio with the project in which you want to add-on audio clip/media file.
Step-2: Create a raw folder.
Step-3: Add media file to raw folder by simply copy and paste that to raw folder.

Step-4: Here we added a media file “ring.mp3” . Now open the Java File of desired activity, here we are adding audio in MainActivity.

Step 5: Further add this code.

MediaPlayer ring= MediaPlayer.create(MainActivity.this,R.raw.ring);
    ring.start();

**Step 6: Now run the App and you will music will play when App will start

**

Place it into your assets folder. Preferably under assets/raw/myfile.mp3
You can access it using:

String mp3File = "raw/music.mp3";
AssetManager assetMan = getAssets();
MediaPlayer media = new MediaPlayer();
FileInputStream mp3Stream = assetMan.openFd(mp3File).createInputStream();
media.setDataSource(mp3Stream.getFD());
media.prepare();
media.start();

You should save the .mp3 into res/raw. AndroidStudio recognizes the raw folder. (By contrast, it does not automatically recognize a res/assets folder).

To play music.mp3:


mediaPlayer = MediaPlayer.create(ctx, R.raw.cat_meow);
mediaPlayer.start();


Note the convenient use of R. syntax.
