What is Dagger (Dagger 2)?
What is a reasonable justification for Dagger being described as promoting better SEPARATION OF CONCERNS within an application's architecture, beyond just automating dependency construction mechanics?
What is a reasonable justification for Dagger being particularly commonly associated with ANDROID development specifically, given that Dagger itself is a general Java/Kotlin dependency injection framework not inherently Android-specific?
What is a reasonable justification for Dagger's compile-time code generation approach being considered advantageous for performance-sensitive Android applications, compared to a reflection-based dependency injection framework?
What is a reasonable comparison between Dagger and Hilt (a more recent dependency injection library built specifically on top of Dagger for Android), given that Hilt has become a commonly recommended choice for newer Android projects?
What is a "Dagger annotation processor," and at what point in a project's build process does it actually run?
What is a reasonable justification for AVOIDING the older "Service Locator" pattern (where a class explicitly asks a central registry for its dependencies at the point of use) in favor of Dagger-style dependency INJECTION (where dependencies are provided to a class from outside, typically via its constructor)?
What is the purpose of the `@Inject` annotation on a class's constructor in Dagger?
What is the purpose of the `@Singleton` scope annotation in Dagger, and what problem does it solve regarding how many instances of a given dependency are created?
What is a reasonable way understanding Dagger's generated code (viewing the actual `DaggerAppComponent.java` file Dagger produces) can help a developer debug a confusing dependency injection issue?
What is "dependency injection" as a general software design pattern, and what problem does Dagger specifically help implement it for?
What is a reasonable justification for the benefit of Dagger catching dependency-configuration errors at COMPILE time (a missing dependency, an ambiguous binding) rather than those same errors only surfacing at RUNTIME (e.g. an app crash when a dependency can't actually be resolved)?
