MainActivity.java

package com.blogspot.devofandroid.myapplication;

import android.database.Cursor;
import android.os.Bundle;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView mAudioListView = (ListView) findViewById(R.id.audioListView);

        ArrayList<String> mAudioList = new ArrayList<>();

        //detail of each audio
        String[] mAudioDetailArray = { MediaStore.Audio.Media._ID, MediaStore.Audio.Media.DISPLAY_NAME};

        //INTERNAL_CONTENT_URI to display audio from internal storage
        //EXTERNAL_CONTENT_URI to display audio from external storage
        Cursor mAudioCursor = getContentResolver().query(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, mAudioDetailArray, null, null, null);

        if(mAudioCursor != null){
            if(mAudioCursor.moveToFirst()){
                do{
                    int audioIndex = mAudioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME);

                    mAudioList.add(mAudioCursor.getString(audioIndex));
                }while(mAudioCursor.moveToNext());
            }
        }
        mAudioCursor.close();

        ArrayAdapter<String> mAdapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,android.R.id.text1, mAudioList);
        mAudioListView.setAdapter(mAdapter);
