使用安卓自带的播放器播放音频

Question

I would like to know how I can android's own player is activated at the time of pressing a button, I have tried but when I press the button the application is destroyed.

This is the location of my mp3 file (Internal Storage / Download / Audio.mp3)

alsoI have added this in the manifest:

<android:name="android.permission.READ_EXTERNAL_STORAGE"/>

My code

button1.setOnClickListener {
           button1.setOnClickListener {

        val audioDirPath = File(getFilesDir(), "Download")
        audioDirPath.mkdir()
        val file = File(audioDirPath, "audionline.mp3")
        val contentUri = getUriForFile(this, "com.example.fileprovider", file)
        val intent = Intent(Intent.ACTION_VIEW)
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        startActivity(intent)

    }
        }

Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
