Unable to put Reverb effect on mp3 audio files for my android application

Question

I'am Unable to put Reverb effect on mp3 audio files for my android application and I've tried the following codes:

        mp = MediaPlayer.create(this, R.raw.audio1);
        PresetReverb pr=new PresetReverb(0,mp.getAudioSessionId());
        pr.setPreset(PresetReverb.PRESET_LARGEHALL);
        pr.setEnabled(true);
        mp.start()

        mp = MediaPlayer.create(this, R.raw.audio1);
        PresetReverb pr=new PresetReverb(1,0);
        pr.setPreset(PresetReverb.PRESET_LARGEHALL);
        mp.attachAuxEffect(pr.getId());
        mp.setAuxEffectSendLevel(1.0f);
        pr.setEnabled(true);
        mp.start();

I've also added required permissions. Anybody please help. I'm not getting any help from android Document as well.

Did you add MODIFY_AUDIO_SETTINGS? You need this if you are using audio session 0. — Techidiot, Sep 15 '15 at 14:18
