Official Android SDK to support:
- Ride Request Button
- Ride Request Deeplinks
- Uber Authentication
- REST APIs
At a minimum, this SDK is designed to work with Android SDK 15.
Before using this SDK, register your application on the Uber Developer Site.
To use the Uber Rides Android SDK, add the compile dependency with the latest version of the Uber SDK.
dependencies {
compile 'com.uber.sdk:rides-android:x.y.z'
}
In order for the SDK to function correctly, you need to add some information about your app. In your application, create a SessionConfiguration
to use with the various components of the library. If you prefer the set it and forget it model, use the UberSdk
class to initialize with a default SessionConfiguration
.
SessionConfiguration config = new SessionConfiguration.Builder()
.setClientId("YOUR_CLIENT_ID") //This is necessary
.setRedirectUri("YOUR_REDIRECT_URI") //This is necessary if you'll be using implicit grant
.setEnvironment(Environment.SANDBOX) //Useful for testing your app in the sandbox environment
.setScopes(Arrays.asList(Scope.PROFILE, Scope.RIDE_WIDGETS)) //Your scopes for authentication here
.build();
The Ride Request Deeplink provides an easy to use method to provide ride functionality against the install Uber app or the mobile web experience.
Without any extra configuration, the RideRequestDeeplink
will deeplink to the Uber app. We
suggest passing additional parameters to make the Uber experience even more seamless for your users. For example, dropoff location parameters can be used to automatically pass the userโs destination information over to the driver:
RideParameters rideParams = new RideParameters.Builder()
.setProductId("a1111c8c-c720-46c3-8534-2fcdd730040d")
.setPickupLocation(37.775304, -122.417522, "Uber HQ", "1455 Market Street, San Francisco")
.setDropoffLocation(37.795079, -122.4397805, "Embarcadero", "One Embarcadero Center, San Francisco")
.build();
requestButton.setRideParameters(rideParams);
After configuring the Ride Parameters, pass them into the RideRequestDeeplink
builder object to
construct and execute the deeplink.
RideRequestDeeplink deeplink = new RideRequestDeeplink.Builder(context)
.setSessionConfiguration(config))
.setRideParameters(rideParameters)
.build();
deeplink.execute();
The Ride Request Deeplink will prefer to use deferred deeplinking by default, where the user is taken to the Play Store to download the app, and then continue the deeplink behavior in the app after installation. However, an alternate fallback may be used to prefer the mobile web experience instead.
To prefer mobile web over an app installation, set the fallback on the builder:
RideRequestDeeplink deeplink = new RideRequestDeeplink.Builder(context)
.setSessionConfiguration(config)
.setFallback(Deeplink.Fallback.MOBILE_WEB)
.setRideParameters(rideParameters)
.build();
deeplink.execute();
The RideRequestButton
offers the quickest ways to integrate Uber into your application. You can add a Ride Request Button to your View like you would any other View:
RideRequestButton requestButton = new RideRequestButton(context);
layout.addView(requestButton);
This will create a request button with deeplinking behavior, with the pickup pin set to the userโs current location. The user will need to select a product and input additional information when they are switched over to the Uber application.
You can also add your button through XML:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:uber="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.uber.sdk.android.rides.RideRequestButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
uber:ub__style="black"/>
</LinearLayout>
To use the uber
XML namespace, be sure to add xmlns:uber="http://schemas.android.com/apk/res-auto"
to your root view element.
The default color has a black background with white text:
<com.uber.sdk.android.rides.RideRequestButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
For a button with a white background and black text:
<com.uber.sdk.android.rides.RideRequestButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
uber:ub__style="white"/>
To specify the mobile web deeplink fallback over app installation when using the
RideRequestButton
:
rideRequestButton.setDeeplinkFallback(Deeplink.Fallback.MOBILE_WEB);
With all the necessary parameters set, pressing the button will seamlessly prompt a ride request confirmation screen.
To further enhance the button with destination and price information, add a Session to it and call loadRideInformation()
function.
RideParameters rideParams = new RideParameters.Builder()
.setPickupLocation(37.775304, -122.417522, "Uber HQ", "1455 Market Street, San Francisco")
.setDropoffLocation(37.795079, -122.4397805, "Embarcadero", "One Embarcadero Center, San Francisco") // Price estimate will only be provided if this is provided.
.setProductId("a1111c8c-c720-46c3-8534-2fcdd730040d") // Optional. If not provided, the cheapest product will be used.
.build();
SessionConfiguration config = new SessionConfiguration.Builder()
.setClientId("YOUR_CLIENT_ID")
.setServerToken("YOUR_SERVER_TOKEN")
.build();
ServerTokenSession session = new ServerTokenSession(config);
RideRequestButtonCallback callback = new RideRequestButtonCallback() {
@Override
public void onRideInformationLoaded() {
}
@Override
public void onError(ApiError apiError) {
}
@Override
public void onError(Throwable throwable) {
}
};
requestButton.setRideParameters(rideParams);
requestButton.setSession(session);
requestButton.setCallback(callback);
requestButton.loadRideInformation();
If you want to provide a more custom experience in your app, there are a few classes to familiarize yourself with. Read the sections below and you'll be requesting rides in no time!
The Uber SDK allows for three login flows: Implicit Grant (local web view), Single Sign On with the Uber App, and Authorization Code Grant (requires a backend to catch the local web view redirect and complete OAuth).
To use SDK features, two configuration details must be set on the Uber Developer Dashboard.
-
Sign into to the developer dashboard
-
Register a redirect URI to be used to communication authentication results. The default used by the SDK is in the format of
applicationId.uberauth://redirect
. ex:com.example .uberauth://redirect
. To configure the SDK to use a different redirect URI, see the steps below. -
To use Single Sign On you must register a hash of your application's signing certificate in the Application Signature section of the settings page of your application.
To get the hash of your signing certificate, run this command with the alias of your key and path to your keystore:
keytool -exportcert -alias <your_key_alias> -keystore <your_keystore_path> | openssl sha1 -binary | openssl base64
Before you can request any rides, you need to get an AccessToken
. The Uber Rides SDK provides the LoginManager
class for this task. Simply create a new instance and use its login method to present the login screen to the user.
LoginCallback loginCallback = new LoginCallback() {
@Override
public void onLoginCancel() {
// User canceled login
}
@Override
public void onLoginError(@NonNull AuthenticationError error) {
// Error occurred during login
}
@Override
public void onLoginSuccess(@NonNull AccessToken accessToken) {
// Successful login! The AccessToken will have already been saved.
}
}
AccessTokenStorage accessTokenStorage = new AccessTokenManager(context);
LoginManager loginManager = new LoginManager(accessTokenStorage, loginCallback);
loginManager.login(activity);
The only required scope for the Ride Request Widget is the RIDE_WIDGETS
scope, but you can pass in any other (general) scopes that you'd like access to. The call to loginWithScopes()
presents an activity with a WebView where the user logs into their Uber account, or creates an account, and authorizes the requested scopes. In your Activity#onActivityResult()
, call LoginManager#onActivityResult()
:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
loginManager.onActivityResult(activity, requestCode, resultCode, data);
}
With Version 0.8 and above of the SDK, the redirect URI is more strongly enforced to meet IETF standards IETF RFC.
The SDK will automatically created a redirect URI to be used in the oauth callbacks with the format "applicationId.uberauth://redirect", ex "com.example.app.uberauth://redirect". This URI must be registered in the developer dashboard
If this differs from the previous specified redirect URI configured in the SessionConfiguration, there are a few options.
- Change the redirect URI to match the new scheme in the configuration of the Session. If this is left out entirely, the default will be used.
SessionConfiguration config = new SessionConfiguration.Builder()
.setRedirectUri("com.example.app.uberauth://redirect")
.build();
- Override the LoginRedirectReceiverActivity in your main manifest and provide a custom intent filter. Register this custom URI in the developer dashboard for your application.
<activity
android:name="com.uber.sdk.android.core.auth.LoginRedirectReceiverActivity"
tools:node="replace">
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data android:scheme="com.example.app"
android:host="redirect" />
</intent-filter>
</activity>
- If using Authorization Code Flow, you will need to configure your server to redirect to the Mobile Application with an access token either via the generated URI or a custom URI as defined in steps 1 and 2.
The Session should be configured to redirect to the server to do a code exchange and the login manager should indicate the SDK is operating in the Authorization Code Flow.
SessionConfiguration config = new SessionConfiguration.Builder()
.setRedirectUri("https://example.com/redirect") //Where this is your configured server
.build();
loginManager.setAuthCodeFlowEnabled(true);
loginManager.login(this);
Once the code is exchanged, the server should redirect to a URI in the standard OAUTH format of
com.example.app.uberauth://redirect#access_token=ACCESS_TOKEN&token_type=Bearer&expires_in=TTL&scope=SCOPES&refresh_token=REFRESH_TOKEN
for the SDK to receive the access token and continue operation.``
The default behavior of calling LoginManager.login(activity)
is to activate Single Sign On,
and if SSO is unavailable, fallback to Implicit Grant if privileged scopes are not requested,
otherwise redirect to the Play Store. If you require Authorization Code Grant, set LoginManager.setAuthCodeFlowEnabled(true)
to use the Authorization Code Flow as the fallback mechanism instead of Implicit Grant or redirecting to the Play Store (regardless of scope).
Implicit Grant will allow access to all non-privileged scopes (and will not grant a refresh token), whereas the other options grant access to privileged scopes. Read more about scopes.
The default behavior of the SSO Deeplink is to open the original Uber app. It is now possible to SSO with the Uber Eats app. To enable SSO with Uber Eats use the LoginManager's setProductFlowPriority
method.
You must specify all apps that you want to SSO with. Only the specified apps will be used.
List<SupportedAppType> appPriorityList = new ArrayList();
appPriorityList.add(SupportedAppType.UBER_EATS);
appPriorityList.add(SupportedAppType.UBER);
loginManager.setProductFlowPriority(appPriorityList).login(this);
Upon a failure to login, an AuthenticationError
will be provided in the LoginCallback
. This enum provides a series of values that provide more information on the type of error.
If your app allows users to authorize via your own customized logic, you will need to create an AccessToken
manually and save it in shared preferences using the AccessTokenManager
.
AccessTokenStorage accessTokenStorage = new AccessTokenManager(context);
Date expirationTime = 2592000;
List<Scope> scopes = Arrays.asList(Scope.RIDE_WIDGETS);
String token = "obtainedAccessToken";
String refreshToken = "obtainedRefreshToken";
String tokenType = "obtainedTokenType";
AccessToken accessToken = new AccessToken(expirationTime, scopes, token, refreshToken, tokenType);
accessTokenStorage.setAccessToken(accessToken);
The AccessTokenManager
can also be used to get an access token or delete it.
accessTokenManger.getAccessToken();
accessTokenStorage.removeAccessToken();
To keep track of multiple users, create an AccessTokenManager for each AccessToken.
AccessTokenManager user1Manager = new AccessTokenManager(activity, "user1");
AccessTokenManager user2Manager = new AccessTokenManager(activity, "user2");
user1Manager.setAccessToken(accessToken);
user2Manager.setAccessToken(accessToken2);
If you would like text fields during signup to be pre-populated with user information you can do so using the ProfileHint API. Partial information is accepted. You will need to supply a ProfileHint object when creating SessionConfiguration instance.
SessionConfiguration configuration = new SessionConfiguration.Builder()
.setClientId(CLIENT_ID)
.setRedirectUri(REDIRECT_URI)
.setScopes(Arrays.asList(Scope.PROFILE, Scope.RIDE_WIDGETS))
.setProfileHint(new ProfileHint
.Builder()
.email("[email protected]")
.firstName("John")
.lastName("Doe")
.phone("1234567890")
.build())
.build();
The Android Uber SDK uses a dependency on the Java Uber SDK for API requests.
After authentication is complete, create a Session
to use the Uber API.
Session session = loginManager.getSession();
Now create an instance of the RidesService
using the Session
RidesService service = UberRidesApi.with(session).createService();
Both synchronous and asynchronous calls work with the Uber Rides Java SDK. The networking stack for the Uber SDK is powered by Retrofit 2 and the same model of threading is available.
Response<UserProfile> response = service.getUserProfile().execute();
if (response.isSuccessful()) {
//Success
UserProfile profile = response.body();
} else {
//Failure
ApiError error = ErrorParser.parseError(response);
}
service.getUserProfile().enqueue(new Callback<UserProfile>() {
@Override
public void onResponse(Call<UserProfile> call, Response<UserProfile> response) {
if (response.isSuccessful()) {
//Success
UserProfile profile = response.body();
} else {
//Api Failure
ApiError error = ErrorParser.parseError(response);
}
}
@Override
public void onFailure(Call<UserProfile> call, Throwable t) {
//Network Failure
}
});
Sample apps can be found in the samples
folder. Alternatively, you can also download a sample from the releases page.
The Sample apps require configuration parameters to interact with the Uber API, these include the client id, redirect uri, and server token. They are provided on the Uber developer dashboard.
Specify your configuration parameters in the sample's gradle.properties file, where examples can be found adhering to the format UBER_CLIENT_ID=insert_your_client_id_here
. These are generated into the BuildConfig during compilation.
For a more idiomatic storage approach, define these in your home gradle.properties file to keep them out of the git repo.
~/.gradle/gradle.properties
UBER_CLIENT_ID=insert_your_client_id_here
UBER_REDIRECT_URI=insert_your_redirect_uri_here
UBER_SERVER_TOKEN=insert_your_server_token_here
To install the sample app from Android Studio, File > New > Import Project and select the extracted folder from the downloaded sample.
