the size of your project. You can limit your project's complexity as it scales up by using <a href="http://web.archive.org/web/20231023212737/https://dagger.dev/" class="external">Dagger</a> to manage dependencies.</p> <p>Dagger automatically generates code that mimics the code you would otherwise have hand-written. Because the code is generated at compile time, it's traceable and more performant than other reflection-based solutions such as <a href="http://web.archive.org/web/20231023212737/https://en.wikipedia.org/wiki/Google_Guice" class="external">Guice</a>.</p> <aside class="note"><strong>Note:</strong><span> Use <a href="/web/20231023212737/https://developer.android.com/training/dependency-injection/hilt-android">Hilt</a> for dependency injection on Android. Hilt is built on top of Dagger and it provides a standard way to incorporate Dagger dependency injection into an Android application.</span></aside> <h2 id="benefits" data-text="Benefits of using Dagger">Benefits of using Dagger</h2> <p>Dagger frees you from writing tedious and error-prone boilerplate code by:</p> <ul> <li><p>Generating the <code translate="no" dir="ltr">AppContainer</code> code (application graph) that you manually implemented in the manual DI section.</p></li> <li><p>Creating factories for the classes available in the application graph. This is how dependencies are satisfied internally.</p></li> <li><p>Deciding whether to reuse a dependency or create a new instance through the use of <em>scopes</em>.</p></li> <li><p>Creating containers for specific flows as you did with the login flow in the previous section using Dagger <em>subcomponents</em>. This improves your app's performance by releasing objects in memory when they're no longer needed.</p></li> </ul> <p>Dagger automatically does all of this at build time as long as you declare dependencies of a class and specify how to satisfy them using annotations. Dagger generates code similar to what you would have written manually. Internally, Dagger creates a graph of objects that it can reference to find the way to provide an instance of a class. For every class in the graph, Dagger generates a <a href="http://web.archive.org/web/20231023212737/https://en.wikipedia.org/wiki/Factory_method_pattern" class="external">factory-type</a> class that it uses internally to get instances of that type.</p> <p>At build time, Dagger walks through your code and:</p> <ul> <li><p>Builds and validates dependency graphs, ensuring that:</p> <ul> <li>Every object's dependencies can be satisfied, so there are no runtime exceptions.</li> <li>No dependency cycles exist, so there are no infinite loops.</li> </ul></li> <li><p>Generates the classes that are used at runtime to create the actual objects and their dependencies.</p></li> </ul> <h2 id="generating-factory" data-text="A simple use case in Dagger: Generating a factory">A simple use case in Dagger: Generating a factory</h2> <p>To demonstrate how you can work with Dagger, let's create a simple <a href="http://web.archive.org/web/20231023212737/https://en.wikipedia.org/wiki/Factory_method_pattern" class="external">factory</a> for the <code translate="no" dir="ltr">UserRepository</code> class shown in the following diagram:</p> <p style="text-align:center;"><img src="/web/20231023212737im_/https://developer.android.com/static/images/training/dependency-injection/3-factory-diagram.png" alt="" width="600"></p> <p>Define <code translate="no" dir="ltr">UserRepository</code> as follows:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> class UserRepository( private val localDataSource: UserLocalDataSource, private val remoteDataSource: UserRemoteDataSource ) { ... } </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> public class UserRepository { private final UserLocalDataSource userLocalDataSource; private final UserRemoteDataSource userRemoteDataSource; public UserRepository(UserLocalDataSource userLocalDataSource, UserRemoteDataSource userRemoteDataSource) { this.userLocalDataSource = userLocalDataSource; this.userRemoteDataSource = userRemoteDataSource; } ... } </pre> </section></div> </div> <p>Add an <code translate="no" dir="ltr">@Inject</code> annotation to the <code translate="no" dir="ltr">UserRepository</code> constructor so Dagger knows how to create a <code translate="no" dir="ltr">UserRepository</code>:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> // @Inject lets Dagger know how to create instances of this object class UserRepository @Inject constructor( private val localDataSource: UserLocalDataSource, private val remoteDataSource: UserRemoteDataSource ) { ... } </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> public class UserRepository { private final UserLocalDataSource userLocalDataSource; private final UserRemoteDataSource userRemoteDataSource; // @Inject lets Dagger know how to create instances of this object @Inject public UserRepository(UserLocalDataSource userLocalDataSource, UserRemoteDataSource userRemoteDataSource) { this.userLocalDataSource = userLocalDataSource; this.userRemoteDataSource = userRemoteDataSource; } } </pre> </section></div> </div> <p>In the above snippet of code, you're telling Dagger:</p> <ol> <li><p>How to create a <code translate="no" dir="ltr">UserRepository</code> instance with the <code translate="no" dir="ltr">@Inject</code> annotated constructor.</p></li> <li><p>What its dependencies are: <code translate="no" dir="ltr">UserLocalDataSource</code> and <code translate="no" dir="ltr">UserRemoteDataSource</code>.</p></li> </ol> <p>Now Dagger knows how to create an instance of <code translate="no" dir="ltr">UserRepository</code>, but it doesn't know how to create its dependencies.

To make Dagger do this, you need to create an interface and annotate it with <code translate="no" dir="ltr">@Component</code>. Dagger creates a container as you would have done with manual dependency injection.</p> <p>Inside the <code translate="no" dir="ltr">@Component</code> interface, you can define functions that return instances of the classes you need (i.e. <code translate="no" dir="ltr">UserRepository</code>). <code translate="no" dir="ltr">@Component</code> tells Dagger to generate a container with all the dependencies required to satisfy the types it exposes. This is called a <em>Dagger component</em>; it contains a graph that consists of the objects that Dagger knows how to provide and their respective dependencies.</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> // @Component makes Dagger create a graph of dependencies @Component interface ApplicationGraph { // The return type of functions inside the component interface is // what can be provided from the container fun repository(): UserRepository } </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> // @Component makes Dagger create a graph of dependencies @Component public interface ApplicationGraph { // The return type of functions inside the component interface is // what can be consumed from the graph UserRepository userRepository(); } </pre> </section></div> </div> <p>When you build the project, Dagger generates an implementation of the <code translate="no" dir="ltr">ApplicationGraph</code> interface for you: <code translate="no" dir="ltr">DaggerApplicationGraph</code>. With its annotation processor, Dagger creates a dependency graph that consists of the relationships between the three classes (<code translate="no" dir="ltr">UserRepository</code>, <code translate="no" dir="ltr">UserLocalDatasource</code>, and <code translate="no" dir="ltr">UserRemoteDataSource</code>) with only one entry point: getting a <code translate="no" dir="ltr">UserRepository</code> instance. You can use it as follows:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> // Create an instance of the application graph val applicationGraph: ApplicationGraph = DaggerApplicationGraph.create() // Grab an instance of UserRepository from the application graph val userRepository: UserRepository = applicationGraph.repository() </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> // Create an instance of the application graph ApplicationGraph applicationGraph = DaggerApplicationGraph.create(); // Grab an instance of UserRepository from the application graph UserRepository userRepository = applicationGraph.userRepository(); </pre> </section></div> </div> <p>Dagger creates a new instance of <code translate="no" dir="ltr">UserRepository</code> every time it's requested.</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> val applicationGraph: ApplicationGraph = DaggerApplicationGraph.create() val userRepository: UserRepository = applicationGraph.repository() val userRepository2: UserRepository = applicationGraph.repository() assert(userRepository != userRepository2) </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> ApplicationGraph applicationGraph = DaggerApplicationGraph.create(); UserRepository userRepository = applicationGraph.userRepository(); UserRepository userRepository2 = applicationGraph.userRepository(); assert(userRepository != userRepository2) </pre> </section></div> </div> <p>Sometimes, you need to have a unique instance of a dependency in a container. You might want this for several reasons:</p> <ol> <li><p>You want other types that have this type as a dependency to share the same instance, such as multiple <code translate="no" dir="ltr">ViewModel</code> objects in the login flow using the same <code translate="no" dir="ltr">LoginUserData</code>.</p></li> <li><p>An object is expensive to create and you don't want to create a new instance every time it's declared as a dependency (for example, a JSON parser).</p></li> </ol> <p>In the example, you might want to have a unique instance of <code translate="no" dir="ltr">UserRepository</code> available in the graph so that every time you ask for a <code translate="no" dir="ltr">UserRepository</code>, you always get the same instance. This is useful in your example because in a real-life application with a more complex application graph, you might have multiple <code translate="no" dir="ltr">ViewModel</code> objects depending on <code translate="no" dir="ltr">UserRepository</code> and you don't want to create new instances of <code translate="no" dir="ltr">UserLocalDataSource</code> and <code translate="no" dir="ltr">UserRemoteDataSource</code> every time <code translate="no" dir="ltr">UserRepository</code> needs to be provided.</p> <p>In manual dependency injection, you do this by passing in the same instance of <code translate="no" dir="ltr">UserRepository</code> to the constructors of the ViewModel classes; but in Dagger, because you are not writing that code manually, you have to let Dagger know you want to use the same instance. This can be done with <em>scope annotations</em>.</p> <h3 id="dagger-scopes" data-text="Scoping with Dagger">Scoping with Dagger</h3> <p>You can use scope annotations to limit the lifetime of an object to the lifetime of its component. This means that the same instance of a dependency is used every time that type needs to be provided.</p> <p>To have a unique instance of a <code translate="no" dir="ltr">UserRepository</code> when you ask for the repository in <code translate="no" dir="ltr">ApplicationGraph</code>, use the same scope annotation for the <code translate="no" dir="ltr">@Component</code> interface and <code translate="no" dir="ltr">UserRepository</code>. You can use the <code translate="no" dir="ltr">@Singleton</code> annotation that already comes with the <code translate="no" dir="ltr">javax.inject</code> package that Dagger uses:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> // Scope annotations on a @Component interface informs Dagger that classes annotated // with this annotation (i.e. @Singleton) are bound to the life of the graph and so // the same instance of that type is provided every time the type is requested. @Singleton @Component interface ApplicationGraph { fun repository(): UserRepository } // Scope this class to a component using @Singleton scope (i.e. ApplicationGraph) @Singleton class UserRepository @Inject constructor( private val localDataSource: UserLocalDataSource, private val remoteDataSource: UserRemoteDataSource ) { ... } </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> // Scope annotations on a @Component interface informs Dagger that classes annotated // with this annotation (i.e. @Singleton) are scoped to the graph and the same // instance of that type is provided every time the type is requested. @Singleton @Component public interface ApplicationGraph { UserRepository userRepository(); } // Scope this class to a component using @Singleton scope (i.e. ApplicationGraph) @Singleton public class UserRepository { private final UserLocalDataSource userLocalDataSource; private final UserRemoteDataSource userRemoteDataSource; @Inject public UserRepository(UserLocalDataSource userLocalDataSource, UserRemoteDataSource userRemoteDataSource) { this.userLocalDataSource = userLocalDataSource; this.userRemoteDataSource = userRemoteDataSource; } } </pre> </section></div> </div> <p>Alternatively, you can create and use a custom scope annotation. You can create a scope annotation as follows:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> // Creates MyCustomScope @Scope @MustBeDocumented @Retention(value = AnnotationRetention.RUNTIME) annotation class MyCustomScope </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> // Creates MyCustomScope @Scope @Retention(RetentionPolicy.RUNTIME) public @interface MyCustomScope {} </pre> </section></div> </div> <p>Then, you can use it as before:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> @MyCustomScope @Component interface ApplicationGraph { fun repository(): UserRepository } @MyCustomScope class UserRepository @Inject constructor( private val localDataSource: UserLocalDataSource, private val service: UserService ) { ... } </pre> </section><section><h3 id="java" data-text="Java">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> @MyCustomScope @Component public interface ApplicationGraph { UserRepository userRepository(); } @MyCustomScope public class UserRepository { private final UserLocalDataSource userLocalDataSource; private final UserRemoteDataSource userRemoteDataSource; @Inject public UserRepository(UserLocalDataSource userLocalDataSource, UserRemoteDataSource userRemoteDataSource) { this.userLocalDataSource = userLocalDataSource; this.userRemoteDataSource = userRemoteDataSource; } } </pre> </section></div> </div> <p>In both cases, the object is provided with the same scope used to annotate the <code translate="no" dir="ltr">@Component</code> interface.
