* Note: If we end up having trouble with this implementation in the future, especially with the rollout
|
|
* of disabling transitive resources, we do have alternative implementations.
|
|
*
|
|
* Probably the most straightforward and high performance would be to implement an interface, have
|
|
* the Application class implement the interface, and allow this to cast the Application object to
|
|
* get the value. If the Application does not implement the interface, then the Mainnet can be the
|
|
* default.
|
|
*
|
|
* Alternatives include
|
|
* - Adding build variants to sdk-ext-lib, ui-lib, and app which gets complex. The current approach
|
|
* or the approach outlined above only requires build variants on the app module.
|
|
* - Using a ContentProvider for dynamic injection, where the URI is defined
|
|
* - Using AndroidManifest metadata for dynamic injection
