Gets a Client Metadata ID at the time of payment activity. Once a user initiates a PayPal payment
from their device, PayPal uses the Client Metadata ID to verify that the payment is
originating from a valid, user-consented device and application. This helps reduce fraud and
decrease declines. This method MUST be called prior to initiating a pre-consented payment (a
"future payment") from a mobile device. Pass the result to your server, to include in the
payment request sent to PayPal. Do not otherwise cache or store this value.

@param context An Android context.
@param request configures what data to collect.
