Top Android App Startup Libraries

Top Android App Startup Libraries.

Introduction​

App startup libraries are essential tools for optimizing the startup time of Android applications. These libraries help reduce initialization and configuration time, thus improving the overall user experience. In this tutorial, we will explore some of the most popular Android app startup libraries and discuss their features and installation process.

1. AndroidX Startup​

AndroidX Startup is an official library provided by Google that helps initialize components in your application during startup. It allows you to define and control the order of initialization for various components such as ContentProviders, WorkManager, and FirebaseApp.

Features:​

  • Supports lazy initialization of components.
  • Provides a clean API for defining dependencies and order of initialization.
  • Automatically handles dependency resolution.

Installation:​

To use AndroidX Startup in your project, add the following dependency to your app-level build.gradle file:

dependencies {
    implementation 'androidx.startup:startup-runtime:1.1.0'
}

Usage:​

To use AndroidX Startup, you need to create a custom initializer class that implements the Startup interface. Here's an example:

class MyInitializer : Initializer<Unit> {
    override fun create(context: Context) {
        // Perform initialization tasks here
    }

    override fun dependencies(): List<Class<out Initializer<*>>> {
        // Define dependencies here
        return emptyList()
    }
}

Next, register your initializer in the AndroidManifest.xml file:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    android:exported="false"
    tools:node="merge">
    <meta-data
        android:name="androidx.startup"
        android:value="MyInitializer" />
</provider>

2. Hilt​

Hilt is a dependency injection library for Android apps built on top of Dagger. It simplifies the process of injecting dependencies into your app's components, such as Activities, Fragments, ViewModels, and more.

Features:​

  • Seamless integration with AndroidX components.
  • Generates optimized code for improved performance.
  • Supports different scopes for managing the lifecycle of dependencies.

Installation:​

To use Hilt in your project, add the following dependencies to your app-level build.gradle file:

android {
    ...
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

dependencies {
    implementation 'com.google.dagger:hilt-android:2.35'
    kapt 'com.google.dagger:hilt-compiler:2.35'
}

Also, add the hilt-android-gradle-plugin to your project-level build.gradle file:

dependencies {
    classpath 'com.google.dagger:hilt-android-gradle-plugin:2.35'
}

Usage:​

To enable Hilt in your application, annotate your Application class with @HiltAndroidApp. Here's an example:

@HiltAndroidApp
class MyApp : Application() {
    ...
}

Next, annotate the components you want to inject dependencies into, such as Activities or Fragments, with @AndroidEntryPoint. Here's an example:

@AndroidEntryPoint
class MyActivity : AppCompatActivity() {
    @Inject
    lateinit var myDependency: MyDependency

    ...
}

Hilt will automatically generate the necessary code to inject the dependencies.
