RxJava Library

RxJava is a reactive programming library for composing asynchronous and event-based programs by using observable sequences.

The Places Rx library lets you receive observable sequences for asynchronus events on the Maps SDK for Android and Places SDK for Android so you can take advantage of the rich set of RxJava features.

Installation

To install the Places Rx library in your Google Maps project:

  1. Add the following dependencies to your module-level build.gradle file:

    dependencies {
        // RxJava bindings for the Maps SDK
        implementation 'com.google.maps.android:maps-rx:1.0.0'
    
        // RxJava bindings for the Places SDK
        implementation 'com.google.maps.android:places-rx:1.0.0'
    
        // It is recommended to also include the latest Maps SDK, Places SDK and RxJava so you
        // have the latest features and bug fixes.
        implementation "com.google.android.gms:play-services-maps:18.2.0"
        implementation 'com.google.android.libraries.places:places:3.3.0'
        implementation 'io.reactivex.rxjava3:rxjava:3.1.8'
    
  2. Rebuild your project in Android Studio to sync these changes.

Example Usage

The following example shows how you can receive a Single, and subscribe to it, when fetching place details:

  placesClient.fetchPlace(
    placeId = "thePlaceId",
    placeFields = listOf(Place.Field.ID, Place.Field.NAME, Place.Field.ADDRESS),
    actions = {}
  ).subscribe(
    { response ->
      Log.d("PlacesRx", "Successfully got place ${response.place.id}")
    },
    { error ->
      Log.e("PlacesRx", "Could not get place: ${error.message}")
    }
  )
}
