Google provides a native package and wits with Google Play Services to satisfy this need, but the question remains of how one creates interactive maps for devices without Play Services. In some countries, the majority of devices are sold without Google Play Services. Device manufacturers who ship their devices without Play Services are standing to proceeds popularity worldwide. In order for our using to provide a truly internationalized experience, we can’t leave out a full-length as hair-trigger as maps. And considering we know other companies have this same issue, we’ve created and unshut sourced AirMapView. AirMapView is a view wresting that enables interactive maps for devices with and without Google Play Services. Devices that do have Google Play Services will use Google Maps V2, while devices without will use a web based implementation of Google Maps. This all comes as one single API that is designed without that of Google Maps V2 that most developers are used to. AirMapView will segregate by default the weightier map provider misogynist for the device. By default it will use native Google Maps V2 if misogynist and fallback to a WebView solution if Google Play Services are not available. The API is designed to be completely transparent to the user so that developers can use the same APIs that are currently used for Google Maps to proceeds the fallback functionality. Native GoogleMap is implemented as a Fragment inside of the AirMapView providing the word-for-word same functionality as using Google Maps V2 directly. Porting existing implementations from GoogleMap to AirMapView is as simple as replacing calls to GoogleMap with calls to AirMapView and implementing the correct callback classes for operations such as OnCameraChanged. The API is designed to be pluggable so developers can add their own providers for specific devices such as Amazon Maps for Amazon kindle fire devices. The fallback webview map displays a Google Map inside of an Android WebView and uses the javascript underpass callbacks to indulge dynamic interaction with the map. Due to it stuff a webview and not native lawmaking it isn’t as performant as the native GoogleMap but it only performed slightly worse in experiments in the Airbnb app. Using the JavascriptUnderpasswe are worldly-wise to implement the same API in the web map so no vendee lawmaking changes are required to support the web map once AirMapView has been implemented for native maps. The web map allows setting a location, centering, subtracting markers, dragging, tapping on the map and other worldwide operations that are currently supported in the GoogleMap. We’ve built AirMapView in such a way that allows us to hands add spare map providers in the future, such as Amazon Maps V2, Baidu, Mapbox, etc.LinksGithub© Airbnb, Inc.© Airbnb, Inc.CareersDesignCareersDesignCareersDesign
