英文:
Audio playback using Android's own player
问题
我想知道如何在按下按钮时启动 Android 自带的播放器，我已经尝试过，但当我按下按钮时应用程序被销毁。
这是我的 mp3 文件位置（内部存储 / Download / Audio.mp3）
另外，我在清单文件中添加了以下内容：
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
我的代码：
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)
}
