You need to register your application, including your digitally signed
.apk file's public certificate in the Google API Console, to be able to use the YouTube Android Player API. The following steps explain how to register your application and certificate as well as how to find your application's authorization credentials.
Create your project and select API services
- Open the Credentials page in the API Console.
This API supports two types of credentials.
Create whichever credentials are appropriate for your project:
OAuth 2.0: Whenever your application requests private user data, it must send an OAuth 2.0 token along with the request. Your application first sends a client ID and, possibly, a client secret to obtain a token. You can generate OAuth 2.0 credentials for web applications, service accounts, or installed applications.
For more information, see the OAuth 2.0 documentation.
API keys: A request that does not provide an OAuth 2.0 token must send an API key. The key identifies your project and provides API access, quota, and reports.
The API supports several types of restrictions on API keys. If the API key that you need doesn't already exist, then create an API key in the Console by clicking Create credentials > API key. You can restrict the key before using it in production by clicking Restrict key and selecting one of the Restrictions.
To keep your API keys secure, follow the best practices for securely using API keys.
