This video discusses issues with the example code and provides an overview how to 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 accesses the in-app billing code…from an activity and constraining ourselves to use…an activity to access in-app billing 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…
