Mobile SDK – Android View Model Provider Key

Android: View Model Provider Key

On Android, you communicate with a PaymentFragment through a PaymentViewModel that is stored in the FragmentActivity containing the PaymentFragment. Normally this means that a single Activity can only contain one PaymentFragment. This should not usually be a problem, but for advanced use cases, you can manually set the storage key for the PaymentViewModel of a given PaymentFragment, allowing for multiple instances to coexist in a single Activity. Further use of multiple simultaneous PaymentFragments is beyond the scope of this document.

The key is set as an argument to the PaymentFragment. You can either use the PaymentFragment.ArgumentsBuilder to build the argument bundle (recommended), or you can manually set a value for the key PaymentFragment.ARG_VIEW_MODEL_PROVIDER_KEY.
