Once an app project has one or more dynamic feature modules added, code will need to be written to install and manage those modules. This will involve performing tasks such as checking whether a module is already installed, installing the module, tracking installation progress and deleting an installed module that is no longer required. All of these tasks are performed using the API provided by the Play Core Library and most of these API calls involve the use of a SplitInstallManager instance which can be created as follows:

private SplitInstallManager manager;

Usually, the first step before allowing the user to launch a dynamic feature is to check that the corresponding module has already been installed. The following code, for example, obtains a list of installed modules and checks if a specific module is installed:

if (manager.getInstalledModules().contains("my_dynamic_feature...
