Explore issues with the example code, and get an overview of how we will improve upon it.
- [Instructor] The sample code for the core part…of In-app Billing is located here.…For the purposes of this course,…we want to make the following changes.…First, we want to create our own IabGateway.…The sample code access is…the In-app Billing code from an activity,…and constraining ourselves to use an activity…to access In-app building can lead to problems.…For example,…if one activity inherits from AppCompatActivity,…but another activity inherits from PreferenceActivity,…and they both require In-app Billing,…then we have a multiple inheritance problem,…because they both cannot extend the activity…that will contain the Iab code.…
We do not want to restrict…how and where the In-app purchasing service can be accessed,…so we will create a standalone class called IabGateway.…The IabGateway can be called from anywhere in our app,…from a fragment, from different activity screens,…or even from a service.…Next we will expose an interface…that will specify the callbacks…that will be used by IabGateway.…This is the IabGatewayListener…
