Class CredentialsProvider

java.lang.Object

com.wallee.android.sdk.credentials.CredentialsProvider

public final class CredentialsProvider
extends java.lang.Object

The credentials provider is responsible to manage and store the Credentials.

Credentials need to be provided by the app backend server. The backend server is responsible to fetch the credentials from the wallee web service. This way the backend server can bind the credentials to the session resp. the app user. This ensures that the backend server controls at any point what the user is allowed to do.

The provider is ensures that the credentials are properly cached and refreshed whenever they are required. For a more persistent storage the CredentialsStore is used.

The implementation is thread-safe and as such the provider can be called from multiple threads.
