How To Get The File Id So I Can Perform A Download Of A File From Google Drive Api On Android?

I am working on an Android project and I am trying to make use of the Google Drive API and I've got most of it working but I am having an issue in how I perform a download. I can'

Solution 1:

In my opinion the easiest and fastest way to get a Google Drive file ID is from Google Drive on the web. Right-click the file name and select Get shareable link. The last part of the link is the file ID. Then you can cancel the sharing.

Solution 2:

This script logs all the file names and ids in the drive:

// Log the name and id of every file in the user's Drivefunction listFiles() {
  var files = DriveApp.getFiles();
  while ( files.hasNext() ) {
    var file = files.next();
    Logger.log( file.getName() + ' ' + file.getId() );
  }
}  

Also, the "Files: list" page has a form at the end that lists the metadata of all the files in the drive, that can be used in case you need but a few ids.

Solution 3:

Well the first option I could think of is that you could send a list request with search parameters for your file, like title="File_1.xml" and fileExtension="xml". It will either return an empty list of files (there isn't one matching the serach criteria), or return a list with at least one file. If it's only one - it's easy. But if there are more - you'll have to select one of them based on some other fields. Remember that in gdrive you could have more than 1 file with the same name. So the more search parameters you provide, the better.

Solution 4:

Click with the right mouse button on the file in your Google Drive. Choose the option to get a link which can be shared from the menu. You will see the file id now. Don't forget to undo the share.

Solution 5:

One way is to associating unique properties with your file while creation.

properties = "{ \
    key='somekey' and \
    value='somevalue'
}"

then create a query.

query ="title = "+"\'"+ title +"\'"+ \
        AND+"mimeType = "+"\'"+ mimeType +"\'"+ \
        AND+"trashed = false"+ \
        AND+"properties has "+ properties

All the file properties(title, etc) already known to you can go here + properties.
