如何使用 API 在 Google Drive 上创建文件夹和文件？ 安卓

Question

I would like to create a folder and a file in Google Drive using Google Drive API in my Android app. I read the document and just give this code:

    File fileMetadata = new File();
    fileMetadata.setName("Invoices");
    fileMetadata.setMimeType("application/vnd.google-apps.folder");

    File file = driveService.files().create(fileMetadata)
            .setFields("id")
            .execute();
    System.out.println("Folder ID: " + file.getId());

But the editor always wants me to create a local variable of driveService . what is driveService ? the quickstart document seems not a example for android?

Answer 1

Drive Android API is deprecated since December 2018, and you should use the REST API , which contains this quickstart .

In this case, the driveService corresponds to an instance of Class Drive , and can be used to call the API through the Java library.

Instantiating Drive requires you to provide credentials . You can see a detailed example in the referenced Java quickstart (where driveService is instead named service ), and can see the different ways of doing this, documented in the library docs : see Drive constructor and Drive.Builder .
