Android Raw folders - creation and reference

The raw folder must be inside the res folder, otherwise it won't work.

Where is the file directory res/raw?

You need to create new directory named raw inside res folder of your project. Then put your .mp3 file inside res>raw folder of your project

I am using MediaPlayer for custom sound. And This is Working fine for me. This is working for all devices.

private MediaPlayer player;

For play custom sound:

 try {
       Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.siren);

       player = MediaPlayer.create(this, uri);
       player.setLooping(true); // This will play sound in repeatable mode.
       player.start();

        } catch (Exception e) {
        e.printStackTrace();
    }

For stop sound:

  if (player != null)
      player.stop();

This is working for me. Hope this will also helps you.

How to reference a File in raw folder in Android

here are 2 functions. one to read from RAW and one from the Assets

/**
 * Method to read in a text file placed in the res/raw directory of the
 * application. The method reads in all lines of the file sequentially.
 */

public static void readRaw(Context ctx,int res_id) {

    InputStream is = ctx.getResources().openRawResource(res_id);
    InputStreamReader isr = new InputStreamReader(is);
    BufferedReader br = new BufferedReader(isr, 8192); // 2nd arg is buffer
                                                        // size

    // More efficient (less readable) implementation of above is the
    // composite expression
    /*
     * BufferedReader br = new BufferedReader(new InputStreamReader(
     * this.getResources().openRawResource(R.raw.textfile)), 8192);
     */

    try {
        String test;
        while (true) {
            test = br.readLine();
            // readLine() returns null if no more lines in the file
            if (test == null)
                break;
        }
        isr.close();
        is.close();
        br.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

and from Assets folder

/**
 * Read a file from assets
 * 
 * @return the string from assets
 */

public static String getQuestions(Context ctx,String file_name) {

    AssetManager assetManager = ctx.getAssets();
    ByteArrayOutputStream outputStream = null;
    InputStream inputStream = null;
    try {
        inputStream = assetManager.open(file_name);
        outputStream = new ByteArrayOutputStream();
        byte buf[] = new byte[1024];
        int len;
        try {
            while ((len = inputStream.read(buf)) != -1) {
                outputStream.write(buf, 0, len);
            }
            outputStream.close();
            inputStream.close();
        } catch (IOException e) {
        }
    } catch (IOException e) {
    }
    return outputStream.toString();

}

Android Studio create A folder in R.raw

You can not add folders to the raw folder or any of the folders inside the res folder.

Android supports only a linear list of files within the predefined folders under res.
The asset folder though, can have an arbitrary hyarchie of folders because the asset folder is not considered as resources.
