Answer 1

mp.start() should be before starting a new activity.

      btnSound.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
            mp.start();
            startActivity(new Intent(currentActivityName.this, newActivityName.class)); 

            }
        });
