2 个解决方案

There are two a APIs that that allow you to do it. 有两个API可以帮助您做到这一点。 The GDAA and the REST . GDAA和REST 。 None of them deals with the mp3 files specifically, though. 不过，它们都没有专门处理mp3文件。 The APIs deal with a binary file content only. 这些API仅处理二进制文件内容。 That means you: 这意味着您：

Find the file first. 首先找到文件。 Either you know the name, mime type,... or you know it's Id. 您可能知道名称，mime类型...，或者您知道它是Id。 If you use REST, the Id can be extracted from the file's URL. 如果使用REST，则可以从文件的URL中提取ID。
Download the content as a binary stream. 将内容下载为二进制流。
Save the content as an mp3 file on Android. 在Android上将内容另存为mp3文件。

If you insist on applying the URL based Id, it is easier to use the REST, since: 如果您坚持应用基于URL的ID，则使用REST更容易，因为：

the URL directly corresponds with the REST Id (aka ResourceId in GDAA) 该网址直接与REST ID（即GDAA中的ResourceId）相对应
you can use the REST playground (bottom) to test things interactively 您可以使用REST操场（底部）以交互方式测试事物

Also, you may use the demo code here to see the (dis)advantages of using one API or another. 另外，您可以在此处使用演示代码来查看使用一个或另一个API的（缺点）优势。 It deals with jpg content instead of mp3, but it has all the building blocks you need. 它处理的是jpg内容而不是mp3，但是它具有您需要的所有构造块。 Be sure you understand the relation of DriveId and ResourceId. 确保您了解DriveId和ResourceId的关系。
