If you have saved file in wav format and want to play it using AudioTrack then follow this code:

             File file=new File(Environment.getExternalStorageDirectory()+"/AudioRecorder/fahim.wav");

               InputStream is;
             DataInputStream         dis = null ;
             BufferedInputStream     bis;

            try 
            {
                is = new FileInputStream(file);
                bis = new BufferedInputStream(is, 8000);
                dis  = new DataInputStream(bis);      //  Create a DataInputStream to read the audio data from the saved file

            }
            catch (FileNotFoundException e1) 
            {
                ShowToast("fILE NOT FOUND:"+e1.getMessage());
            }

            int i = 0;                                                          //  Read the file into the "music" array
            music=new byte[(int) file.length()];
            try 
            {
                while (dis.available() > 0)
                {
                    music[i] = dis.readByte();                                      //  This assignment does not reverse the order
                    i++;
                }
            } 
            catch (IOException e) 
            {
                ShowToast("I/O Exception:"+e.getMessage());
            }

            try {dis.close();} catch (IOException e) {e.printStackTrace();}

            int minBufferSize = AudioTrack.getMinBufferSize(11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);

            AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM);
            at.play();

            ShowToast("size:"+music.length);
            //*/
            at.write(music, 0, music.length);
