Mortar is a Java library for Android that pairs thin views with dedicated presenters, providing a simplified, composable overlay on the Android Activity lifecycle. It uses Context#getSystemService to supply services like dependency injection (Dagger) and bundle persistence via MortarScope singletons.
Use cases
- manage Android view state across configuration changes
- implement MVP architecture on Android
- survive Activity recreation with persisted presenters
- scope Dagger dependency graphs to screens or wizard sessions
- decouple presenters from Android view lifecycle
When to choose
- maintaining a legacy Android app already built on Mortar
- you specifically want the Views-as-modular-unit MVP pattern with Dagger 1/2
When to avoid
- starting a new Android project - it is deprecated in favor of Square Workflow
- you want Jetpack ViewModels or modern Android architecture components
- you need a library with active community support
