Lyft Android SDK

The Official Lyft Android SDK makes it easy to integrate Lyft into your app. More specifically, it provides:

• An easily configurable Lyft button which can display cost, ETA, and ride type. Tapping the button deeplinks into the Lyft app with pre-filled pickup/destination/ridetype.
• A Java interface for making sync/async calls to Lyft's REST APIs
• Two sample Android Activities that show how to use the SDK components.

Registration

• You must first create a Lyft Developer account here.
• Once registered, you will be assigned a Client ID and will be able to generate Client Tokens.

Setup and Installation

Gradle:

repositories {
  mavenCentral() // or jcenter()
}

dependencies {
    compile 'com.lyft:lyft-android-sdk:2.0.2'
}

If you only want to use the Lyft API Wrapper or Deeplink portion of the SDK, you can pull them individually.

compile 'com.lyft:lyft-android-sdk-networking:2.0.2'  // Lyft API Wrapper
compile 'com.lyft:lyft-android-sdk-deeplink:2.0.2'    // Deeplink

Maven:

<dependency>
  <groupId>com.lyft</groupId>
  <artifactId>lyft-android-sdk</artifactId>
  <version>2.0.2</version>
  <type>aar</type>
</dependency>

Lyft Button

Adding the Lyft Button in an XML layout is as simple as:

<com.lyft.lyftbutton.LyftButton
    android:id="@+id/lyft_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    lyft:lyftStyle="lyftMulberryDark"
    />

We recommend setting the width/height to wrap_content, which results in a width of 260dp and a height of 50dp. Otherwise, please keep in mind that a smaller width/height may result in undesirable UI, such as overlapping text.

To load ETA/cost:

ApiConfig apiConfig = new ApiConfig.Builder()
        .setClientId("your_client_id")
        .setClientToken("your_client_token")
        .build();

LyftButton lyftButton = (LyftButton) findViewById(R.id.lyft_button);
lyftButton.setApiConfig(apiConfig);

RideParams.Builder rideParamsBuilder = new RideParams.Builder()
        .setPickupLocation(37.7766048, -122.3943576)
        .setDropoffLocation(37.759234, -122.4135125);
rideParamsBuilder.setRideTypeEnum(RideTypeEnum.STANDARD);

lyftButton.setRideParams(rideParamsBuilder.build());
lyftButton.load();

Addresses can also be used for pickup/dropoff locations. Each address results in an extra API call to obtain the corresponding lat/lng pair. Therefore, we recommend using lat/lng values directly if they are available.

RideParams.Builder rideParamsBuilder = new RideParams.Builder()
        .setPickupAddress("185 Berry St, San Francisco, CA 94107")
        .setDropoffAddress("2300 Harrison St, San Francisco, CA 94110");

Ride types

Lyft is growing very quickly and is currently available in these cities. Please keep in mind that some ride types (such as Lyft Line) are not yet available in all Lyft cities. If you set the ride type of the button and it happens to be unavailable, the button will default to the Lyft Standard ride type. You can utilize the /v1/ridetypes endpoint to get a list of the available ride types in an area.

Button styles

To specify the button style via XML, use the lyft:lyftStyle attribute or set it programmatically:

lyftButton.setStyle(LyftStyle.MULBERRY_DARK);

There are 5 styles to pick from:

Lyft API Wrapper

The SDK provides wrapper methods around Lyft's REST APIs - this can be helpful when you want to build a more custom integration with the Lyft platform vs making HTTP requests directly.

The SDK uses Square's Retrofit 2 networking library. For each Lyft API endpoint, there is a corresponding Java method. The return type is a Call object which can be executed synchronously or asynchronously. See LyftApi.java for all the API methods.

LyftApi lyftPublicApi = new LyftApiFactory(apiConfig).getLyftApi();
Call<EtaEstimateResponse> etaCall = lyftPublicApi.getEtas(37.7766048, -122.3943576, "lyft");

Asynchronous:

etaCall.enqueue(new Callback<EtaEstimateResponse>() {
    @Override
    public void onResponse(Call<EtaEstimateResponse> call, Response<EtaEstimateResponse> response) {
        EtaEstimateResponse etaEstimateResponse = response.body();
        Eta eta = etaEstimateResponse.eta_estimates.get(0);
    }

    @Override
    public void onFailure(Call<EtaEstimateResponse> call, Throwable t) {
        Log.d("MyApp", t.toString());
    }
});

Synchronous:

EtaEstimateResponse etaEstimateResponse = etaCall.execute().body();
Eta eta = etaEstimateResponse.eta_estimates.get(0);

RxJava Observables

If you already use RxJava (your app must have it as a dependency), then you can obtain an Observable instead of a Call object. Simply use LyftApiRx instead of LyftApi.

LyftPublicApiRx lyftPublicApiRx = new LyftApiFactory(apiConfig).getLyftPublicApiRx();
Observable<EtaEstimateResponse> etaObservable = lyftPublicApiRx.getEtas(37.7766048, -122.3943576, "lyft");

ProGuard

If you are directly using the Lyft Wrapper API without using the Lyft Button, then you may need to add the the ProGuard rules for Retrofit. Please see proguard-rules.pro. This only applies if you are using ProGuard.

Deeplinking

The SDK provides direct deeplinking to the Lyft app for those developers who prefer to handle their own custom deeplinking vs relying on the Lyft Button.. The deeplink module of the SDK includes this logic and makes it easy to launch the Lyft app.

DeepLinkParams deepLinkParams = new DeepLinkParams.Builder()
        .setClientId("your_client_id")
        .setRideType(RideTypeEnum.SHARED)
        .setPickupLocation(37.7766048, -122.3943576)
        .setDropoffLocation(37.759234, -122.4135125)
        .build();

DeepLink.launchLyftApp(getContext(), deepLinkParams);

Sample Activities

Checkout the sample activites which are included in the SDK, in the sample-app module:

• SampleBasicActivity: Includes minimal code to set up the Lyft Button.
• SampleLocationAwareActivity: Gets the device's current GPS location and calls the /v1/ridetypes endpoint to get a list of the available ride types in the area (i.e. Lyft Line, Lyft Plus, etc). The user is able to select an available ride type via a dropdown. The Lyft Button then displays the current ETA and cost of that ride type to a specified destination.

You can specify which activity to launch in the sample-app's AndroidManifest.xml.
