CredentialProvider

public interface CredentialProvider

Provider interface to be implemented by system credential providers that will fulfill Credential Manager requests. The implementation must have a constructor that takes in a context.

Note that for SDK version 33 and below, this interface can be implemented by any OEM provider that wishes to return credentials. The implementation must have a constructor with a context parameter. A provider must :

1. Release a dedicated provider library that developers can add as a dependency.
2. Include an empty CredentialProviderService in the provider library for the purposes of exposing a meta-data tag in the Android Manifest file.
3. Add the name of the class that is implementing this interface, as a value to the meta-data tag described above.
4. Make sure that there is only one provider implementation on the device. If the device already has a provider installed, and the developer specifies more than one provider dependencies, credential manager will error out.

For SDK version 34 and above, this interface will only be implemented by an internal class that will route all requests to the android framework. Providers will need to register directly with the framework to provide credentials.
