implementation 'com.github.siddhantkushwaha:todd:version'You can use a many steps manual option, or the 6 steps 'Quickstart' workaround.
Manual/customized:
-
Fill in Project Name, like "todd-Testing" or so, leave Location unchanged
-
Change Project ID (optional)
-
Click "CREATE"
-
Wait a couple of seconds until the project is created and open it (click "VIEW")
-
On the APIs pane, click "Go to APIs overview"
-
Click "ENABLE APIS AND SERVICES"
-
Enter "Drive", select "Google Drive API"
-
Click "ENABLE"
-
Go to "Credentials" menu in the left menu bar
-
Click "CONFIGURE CONSENT SCREEN"
-
Choose "External", click "CREATE"
-
Fill in something like "todd" in the "Application name" box
-
At the bottom click "Save"
-
Go to "Credentials" menu in the left menu bar (again)
-
Click "CREATE CREDENTIALS"
-
Select "OAuth client ID"
-
Select "Desktop app" as "Application type"
-
Change the name (optional)
-
Click "Create"
-
Click "OK" in the "OAuth client created" dialog
-
In the "OAuth 2.0 Client IDs" section click on the just create Desktop app line.
-
In the top bar, click "DOWNLOAD JSON"
-
You will get a file like "client_secret_xxxxxx.apps.googleusercontent.com.json", rename it to "credentials.json" and copy this in
src/main/resourcesdirectory.
This will 'abuse' a 'Quickstart' project.
-
Go to https://developers.google.com/drive/api/v3/quickstart/python
-
Click the "Enabled the Drive API"
-
"Desktop app" will already be selected on the "Configure your OAuth client" dialog
-
Click "Create"
-
Click "DOWNLOAD CLIENT CONFIGURATION"
-
You will get a file like "credentials.json", and put this in
src/main/resourcesdirectory.
On the first use, you will get a browser screen that you need to grant access for it, and because we haven't granted out OAuth consent screen (This app isn't verified), we get an extra warning. You can use the "Advanced" link, and use the "Go to yourappname (unsafe)" link.
Should look like this -
{
"installed": {
"client_id": "********.apps.googleusercontent.com",
"project_id": "******",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_secret": "*********",
"redirect_uris": ["urn:ietf:wg:oauth:2.0:oob", "http://localhost"]
