Я использую contenResolver для запроса всех песен из Mediastore.Аудио. Вот код:

 package com.example.beethozart

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.provider.MediaStore
import timber.log.Timber
import java.io.File

class MainActivity : AppCompatActivity() {

        private fun getAudioDirectories() {

            val uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
            contentResolver.query(uri, null, null, null, null)?.let {
                it.moveToFirst()

                val pathIndex = it.getColumnIndex(MediaStore.Audio.Media.DATA)

                do {
                    val path = it.getString(pathIndex)
                    Timber.i(path)
                } while (it.moveToNext())
            }
        }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        getAudioDirectories()
    }
}
 

Проблема в том, что он находит не все песни с устройства, а только некоторые песни в определенной папке. Вот журнал:

Есть ли какой-нибудь способ это исправить?
