An Android library for the Yelp Fusion API v3. It simplifies the process of authentication, request construction, and response parsing for Android developers using the Yelp API v3. This clientlib has been tested with applications written in Android API level 15 and 25. This library inspired by YelpAndroid

This library uses a YelpFusionApi object to query against the API. Instantiate a YelpFusionApi object by using
YelpFusionApiFactory with your API key.
YelpFusionApiFactory apiFactory = new YelpFusionApiFactory();
YelpFusionApi yelpFusionApi = apiFactory.createAPI(apiKey);Once you have a YelpFusionApi object you can use the getBusinessSearch 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", "indian food");
params.put("latitude", "40.581140");
params.put("longitude", "-111.914184");
Call<SearchResponse> call = yelpFusionApi.getBusinessSearch(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>() {
@Override
public void onResponse(Call<SearchResponse> call, Response<SearchResponse> response) {
SearchResponse searchResponse = response.body();
// Update UI text with the searchResponse.
}
@Override
public void onFailure(Call<SearchResponse> call, Throwable t) {
// HTTP error happened, do something to handle it.
}
};
call.enqueue(callback);Additionally there are two more search methods for searching by a Phone or for Transaction:
// Phone Search
Call<SearchResponse> call = yelpFusionApi.getPhoneSearch("+18014384823");
Response<SearchResponse> response = call.execute();
// Transaction Search
Call<SearchResponse> call = yelpFusionApi.getTransactionSearch("delivery", params);
Response<SearchResponse> response = call.execute();To query the Business API, use the getBusiness function with a id.
Call<Business> call = yelpFusionApi.getBusiness("saffron-valley-south-jordan");
Response<Business> response = call.execute();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>() {
@Override
public void onResponse(Call<Business> call, Response<Business> response) {
Business business = response.body();
// Update UI text with the Business object.
}
@Override
public void onFailure(Call<Business> call, Throwable t) {
// HTTP error happened, do something to handle it.
}
};
Call<Business> call = yelpFusionApi.getBusiness(id);
call.enqueue(callback);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 = yelpFusionApi.getBusiness(businessId);
call.enqueue(callback);
// Activity is being destroyed and the call should be canceled.
call.cancel();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 = yelpFusionApi.getBusinessSearch(params);
SearchResponse searchResponse = call.execute().body();
int totalNumberOfResult = searchResponse.getTotal(); // 3
ArrayList<Business> businesses = searchResponse.getBusinesses();
String businessName = businesses.get(0).getName(); // "JapaCurry Truck"
Double rating = businesses.get(0).getRating(); // 4.0Business responses are parsed into Business objects directly.
Call<Business> call = yelpFusionApi.getBusiness("japacurry-truck-san-francisco");
Response<Business> response = call.execute();
Business business = response.body();
String businessName = business.getName(); // "JapaCurry Truck"
Double rating = business.getRating(); // 4.0For a full list of available response fields, take a look at the documentation or the classes defined in com.yelp.fusion.client.models.
- Fork it (https://github.com/ranga543/yelp-fusion-android/fork)
- Create your feature branch (git checkout -b my-new-feature)
- Commit your changes (git commit -am 'Add some feature')
- Push to the branch (git push origin my-new-feature)
- 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 Fusion API. You can set this up by putting
your API keys into src/test/resources/credentials.yaml in the following format:
api_key: YOUR_API_KEY
To run the integration tests, execute ./gradlew integrationTest. Integration tests will not be ran in the build
process by executing ./gradlew build.
