Latest commit c9ed1aa Jan 19, 2017

Build Status


An Android library for the Yelp API v2. It simplifies the process of authentication, request construction, and response parsing for Android developers using the Yelp API v2. This clientlib has been tested with applications written in Android API level 15 and 25.


Download the latest AAR or install by using Maven:


or Gradle:

repositories {

dependencies {
    compile 'com.yelp.clientlib:yelp-android:3.0.0'

Proguard rules for the library can be found here


Basic usage

This library uses a YelpAPI object to query against the API. Instantiate a YelpAPI object by using YelpAPIFactory with your API keys.

YelpAPIFactory apiFactory = new YelpAPIFactory(consumerKey, consumerSecret, token, tokenSecret);
YelpAPI yelpAPI = apiFactory.createAPI();

Search API

Once you have a YelpAPI object you can use the search function to generate a Call object which makes a request to the Search API.

The general params and locale options should be passed to the method as a Map<String, String>. The full list of parameters can be found in the Search API Documentation.

Map<String, String> params = new HashMap<>();

// general params
params.put("term", "food");
params.put("limit", "3");

// locale params
params.put("lang", "fr");

Call<SearchResponse> call ="San Francisco", params);

Now you can execute the Call object to send the request.

Response<SearchResponse> response = call.execute();

You can also pass in a Callback object to send the request asynchronously. For more see Asynchronous Requests section.

Callback<SearchResponse> callback = new Callback<SearchResponse>() {
    public void onResponse(Call<SearchResponse> call, Response<SearchResponse> response) {
        SearchResponse searchResponse = response.body();
        // Update UI text with the searchResponse.
    public void onFailure(Call<SearchResponse> call, Throwable t) {
        // HTTP error happened, do something to handle it.


Additionally there are two more search methods for searching by a bounding box or for geographical coordinates:

// bounding box
BoundingBoxOptions bounds = BoundingBoxOptions.builder()
Call<SearchResponse> call =, params);
Response<SearchResponse> response = call.execute();

// coordinates
CoordinateOptions coordinate = CoordinateOptions.builder()
Call<SearchResponse> call =, params);
Response<SearchResponse> response = call.execute();

Business API

To query the Business API, use the getBusiness function with a business_id. You can also pass in locale parameters in a Map<String, String> as specified in the Business API Documentation.

Call<Business> call = yelpAPI.getBusiness("yelp-san-francisco");
Response<Business> response = call.execute();

You can pass in locale information as well.

Map<String, String> params = new HashMap<>();
params.put("lang", "fr");

Call<Business> call = yelpAPI.getBusiness("yelp-san-francisco", params);
Response<Business> response = call.execute();

Phone Search API

To query the Phone Search API, use the getPhoneSearch function with a phone number. Additional parameters can be passed in by using a Map<String, String> as specified in the Phone Search API Documentation.

Call<SearchResponse> call = yelpAPI.getPhoneSearch("+15555555555");
Response<SearchResponse> response = call.execute();

You can pass in country code information as well

Map<String, String> params = new HashMap<>();
params.put("cc", "US");
params.put("category", "fashion");

Call<SearchResponse> call = yelpAPI.getPhoneSearch("5555555555", params);
Response<SearchResponse> response = call.execute();

Asynchronous Requests

This library uses Retrofit as the HTTP client. To send a request asynchronously, use Call.enqueue() to set Callback function for an asynchronous request.

Callback<Business> callback = new Callback<Business>() {
    public void onResponse(Call<Business> call, Response<Business> response) {
        Business business = response.body();
        // Update UI text with the Business object.
    public void onFailure(Call<Business> call, Throwable t) {
        // HTTP error happened, do something to handle it.

Call<Business> call = yelpAPI.getBusiness(businessId);

You can cancel asynchronous requests by simply call cancel() on Call objects. It is important to cancel your calls while your Activity is being destroyed to avoid memory leaks.

Call<Business> call = yelpAPI.getBusiness(businessId);

// Activity is being destroyed and the call should be canceled.

For more information about the usage of asynchronous requests in Retrofit, see Retrofit documentation.


After Call object is executed, a Response contains parsed Java objects will be returned, use Response.body() to get parsed Java objects.

Search and phone search responses are parsed into SearchResponse objects.

Call<SearchResponse> call ="San Francisco", params);
SearchResponse searchResponse = call.execute().body();

int totalNumberOfResult =;  // 3

ArrayList<Business> businesses = searchResponse.businesses();
String businessName = businesses.get(0).name();  // "JapaCurry Truck"
Double rating = businesses.get(0).rating();  // 4.0

Business responses are parsed into Business objects directly.

Call<Business> call ="japacurry-truck-san-francisco");
Response<Business> response = call.execute();
Business business = response.body();

String businessName =;  // "JapaCurry Truck"
Double rating = business.rating();  // 4.0

For a full list of available response fields, take a look at the documentation or the classes defined in com.yelp.clientlib.entities.


  1. Fork it (
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request


Please write tests for any new features. We use JUnit + Gradle so just run ./gradlew test to run the full test suite. To know more about running JUnit tests in Gradle, see [Gradle: The Java Plugin - Test](https://docs.gradle .org/current/userguide/java_plugin.html#sec:java_test).

If you are adding a new integration test, you will need to connect to the Yelp API. You can set this up by putting your API keys into src/integration-test/resources/credentials.yaml in the following format:

consumer_key: YOUR_CONSUMER_KEY
consumer_secret: YOUR_CONSUMER_SECRET
token_secret: YOUR_TOKEN_SECRET

To run the integration tests, execute ./gradlew integrationTest. Integration tests will not be ran in the build process by executing ./gradlew build.

You can’t perform that action at this time.
