Instructions for the Calendar App Engine Sample

Browse Source Code

• Browse Source or main file CalendarAppEngineSample.java

Register Your Application

• Visit the Google apis console
• If this is your first time, click "Create project..."
• Otherwise, click on the drop down under the "Google apis" logo at the top left, and click "Create..." under "Other projects".
• Click on "API Access", and then on "Create an OAuth 2.0 Client ID...".
• Enter a product name and click "Next".
• Select "Web application", select "more options" and enter some redirect URIs, for example "https://yourappname.appspot.com/oauth2callback" and "http://localhost:8888/oauth2callback". Click "Create client ID".
• In the newly created "Client ID for web applications", click "Download JSON" on the right side. Later on after you check out the sample project, you will copy this downloaded file (e.g. ~/Downloads/client_secrets.json) to src/main/resources/client_secrets.json. Otherwise you would get a 400 INVALID_CLIENT error in the browser when running the sample.
