Android Studio and Google Drive API (Uploading video to Google Drive)

Question

I followed the quickstart guide from Google to take an image and afterwards upload it to the users Google Drive.

My question is, how can i adapt this to using video and uploading video to Google Drive instead of an image? I already know how to access and record video's using intents (and saving it on the external storage) but not how to upload afterwards. My guess is it would be pretty much the same as the following code, but again not sure.

Any help will be appreciated!

 * in Google Drive. The user is prompted with a pre-made dialog which allows
 * them to choose the file location.

        OnConnectionFailedListener {

    private static final String TAG = "drive-quickstart";

    private static final int REQUEST_CODE_CREATOR = 2;
    private static final int REQUEST_CODE_RESOLUTION = 3;

    private Bitmap mBitmapToSave;

        final Bitmap image = mBitmapToSave;
        Drive.DriveApi.newDriveContents(mGoogleApiClient)

Answer 1

In the code snippet, you can try to change the mimeType to application/vnd.google-apps.video and the Bitmap typecast to (lets say) byte[] . I'm just not certain since this involves possibly large files and there's no documentation on the Android Drive API page about video uploads.

There are other ways to approach this, though. What I can suggest is for you to utilize the REST calls in uploading files .

For videos (which usually has a large file size), I'd suggest you use Resumable Uploads. It does have some prerequisites you'll need to do

The steps for using resumable upload include:

1. Start a resumable session. Make an initial request to the upload URI that includes the metadata, if any.

2. Save the resumable session URI. Save the session URI returned in the response of the initial request; you'll use it for the remaining requests in this session.

3. Upload the file. Send the media file to the resumable session URI.

More information can be found on the documentation.

Happy coding!
