Key actions include using callbacks to calculate custom macro values (`Container.FunctionCallMacroCallback`) and execute custom tags (`Container.FunctionCallTagCallback`, `CustomTagProvider`). `ContainerHolder` manages active containers, with `ContainerHolder.ContainerAvailableListener` signaling new container availability. `DataLayer` stores app information. `InstallReferrerReceiver` and `InstallReferrerService` handle Google Play install data. `PreviewActivity` and `TagManagerPreviewActivity` handle preview versions, while `TagManager` is the main GTM implementation.\n"]]
