Download

// RxPreferences:
implementation "dev.drewhamilton.rxpreferences:rxpreferences:$version"
// With Kotlin extensions:
implementation "dev.drewhamilton.rxpreferences:rxpreferences-ktx:$version"
// Dagger component:
implementation "dev.drewhamilton.rxpreferences:rxpreferences-dagger:$version"

Usage

RxPreferences

Get the current value of any preference:

rxPreferences.getIntOnce("Language count", 0)
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(count -> displayCount(count));

Observe the initial value plus any changes to a preference:

rxPreferences.getStringStream("Favorite language", "None")
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(name -> displayBestFriend(name));

Edit preferences and monitor the completion of committing those changes:

rxPreferences.edit()
        .putInt("Language count", 1)
        .putString("Favorite language", "Java")
        .commit()
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(() -> showSavedIndicator(), error -> displayError(error));

Kotlin extensions

With Kotlin extensions, use the Editor as a receiver:

rxPreferences.edit {
    putInt("Language count", 2)
    putString("Favorite language", "Kotlin")
}.subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe({ showSavedIndicator() }, { error -> displayError(error) })

Dagger component

Easily provide and access RxPreferences instances using RxPreferencesComponent:

@Module
object PersistenceModule {

    private const val sharedPreferencesName = "example.SharedPreferences"

    private val ExampleApplication.sharedPreferences
        get() = getSharedPreferences(sharedPreferencesName, Context.MODE_PRIVATE)

    @JvmStatic
    @Provides
    fun preferencesComponent(application: ExampleApplication) =
        RxPreferencesComponent.create(application.sharedPreferences)

    @JvmStatic
    @Provides
    @Reusable
    fun preferences(preferencesComponent: RxPreferencesComponent) =
        preferencesComponent.rxPreferences()
}
