Android：将Google Drive集成到应用中

Question

I have been following this tutorial to integrate google drive in my app. However error occurs when running the app.

The error:

The following error occured: 400 Bad Request
{
"code":400,
"errors":[{
"domain":"global",
"location":"fiels",
"locationType":"parameter",
"message": "Invalid field selection items",
"reason":"invalidParameter"
}],
"message":"Invalid field selection items"
}

When I debugged this code I found the code is not executing beyond:

private List<String> getDataFromApi() throws IOException {
            // Get a list of up to 10 files.
            List<String> fileInfo = new ArrayList<String>();
            FileList result = mService.files().list()
                 .setPageSize(10)
                 .setFields("nextPageToken, items(id, name)")
                 .execute();

Here is the next step from the code that I have used:

List<com.google.api.services.drive.model.File> files = result.getFiles();
            if (files != null) {
                for (com.google.api.services.drive.model.File file : files) {
                    fileInfo.add(String.format("%s (%s)\n",
                            file.getName(),file.getId() ));
                }
            }
            return fileInfo;
        }

In the manifest I have defined:

<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
 <uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

and inside application in manifest:

<meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <meta-data
            android:name="com.google.android.gms.games.APP_ID"
            android:value="99102****479" />
        <meta-data
            android:name="com.google.android.gms.appstate.APP_ID"
            android:value="99102****479" />

I don't know what the problem is. Please Help. Thank you.

Answer 1

I did the same tutorial a couple of days ago and got same problem, some how they did not updated their tutorial since in this line:

    .setFields("nextPageToken, items(id, name)")

have to be changed to

    .setFields("nextPageToken, files(id, name)")

as they explain in the search for files section .

Hope this helps!
