    Parameters:
    
    clientToken - base64 string containing information about this Primer session.
  - getRequiredInputElementTypes
```
 List<PrimerInputElementType> getRequiredInputElementTypes(String paymentMethodType)
```
    Gets the PrimerInputElementType for a given paymentMethodType
  - makeView
```
 View makeView(String paymentMethodType, ViewGroup container)
```
    Creates View for a given paymentMethodType
    
    Parameters:
