There is no need to save the music in your own app's database, android saves them for you and provides a content provider (MediaStore) that allows you restricted access to the content of that database. So every time your app wants to load music from the device, it would use the load music from the Media Store, making your own database would only mean having a copy of the data in the device and that would be waste of memory since you would still have to query your database to get the music. you can learn more about content providers and media store from the following tutorials. Media Store
无需将音乐保存在您自己的应用程序数据库中,android会为您保存它们,并提供允许您限制访问该数据库内容的内容提供程序(MediaStore)。因此,每当您的应用程序想要从设备加载音乐时,它将使用来自媒体商店的加载音乐,使您自己的数据库只意味着在设备中拥有数据的副本,这将浪费内存,因为您会仍然需要查询您的数据库才能获得音乐。您可以从以下教程中了解有关内容提供商和媒体商店的更多信息。媒体商店
