mahdiPourkazemi / constants.kt

Created July 29, 2025 11:13

This snippet demonstrates a better way to inject constant values using Hilt in Android. Instead of relying on a centralized Constants.kt file and @nAmed strings (which are error-prone and hard to refactor), it uses custom @qualifier annotations. This approach provides compile-time safety, clearer dependency injection, and easier maintenance.

	@Qualifier
	@Retention(AnnotationRetention.BINARY)
	annotation class SharedPreferencesFileNameKey

	@Qualifier
	@Retention(AnnotationRetention.BINARY)
	annotation class LanguageCodeKey

	@Module
	@InstallIn(SingletonComponent::class)

SAM applications in android

	fun interface OnAction {
	fun execute(context: Context)

	companion object {
	fun withLogging(tag: String = "MyAction",
	message: String = "Button clicked",
	action: (Context) -> Unit
	): OnAction {
	return OnAction { context ->
	Log.d(tag, message)

mahdiPourkazemi / NavTypeParcelableMapper.kt

Created July 21, 2025 06:55

This Kotlin extension defines a custom NavType<T> mapper for use with Jetpack Navigation when passing Parcelable objects between destinations. It also integrates Kotlinx Serialization (@serializable) for safely encoding and decoding data into string format when navigating via routes. The mapper() function simplifies handling complex objects like…

	import android.os.Build
	import android.os.Bundle
	import android.os.Parcelable
	import androidx.navigation.NavType
	import kotlinx.parcelize.Parcelize
	import kotlinx.serialization.Serializable
	import kotlinx.serialization.encodeToString
	import kotlinx.serialization.decodeFromString
	import kotlinx.serialization.json.Json

I think using use-case with mvi in this approach is better (model A vs model B) #android #kotlin #mvvm #mvi
