从Google Drive API下载任何文件

Question

I'm a Google Drive API rookie. In my app, I integrate Google Drive Api to allows user search in its Drive folders an specific extension files (.gpx). I use newOpenFileActivityBuilder() in IntentSender, so user can pick the file he wants.

String[] mimeTypes = {"unknown/unknown","application/octet-stream","application/type"};

IntentSender intentSender = Drive.DriveApi
            .newOpenFileActivityBuilder()
            .setMimeType(mimeTypes)
            .build(gDriveclient);

My problem is the .gpx files are not selectable, I have tried a lot of different mime types, but none works.

Any idea? Thanks in advance!

You need to provide the MIME type for the .gpx file. You could find it out by looking at the MIME type in the get response: https://developers.google.com/drive/v2/reference/files/get
