sequencer.start() method not generating any sound in Android application.

[HirenParekh]

i made a sequencer object as follows
sequencer = MidiSystem.getSequencer();
than open it using open method
sequencer.open();
than i tried to set a sequence and start the sequencer,
InputStream inputStream = getResources().openRawResource(R.raw.airtel_new);
sequence = MidiSystem.getSequence(inputStream);

        sequencer.setSequence(sequence);
        sequencer.start();

But it does not produce any sound in my android application.
