We then launch the Activity. Then, select your Activity type ( For Example Navigation Drawer Activity, Empty Activity, etc.). What if your server goes down for a while? This MockRetrofit object wraps around the dummy implementation that we created and emulates a network call by adding delays to the calls. OnFailure will be called if something in the process of communicating with the server or processing the response went wrong. I have the runner in defaultConfig section and have it selected in run configuration as well. You should definitely learn how to handle RESTful Web Services, as their correct implementation is the core knowledge while creating modern apps. OnFailure will be called if something in the process of communicating with the server or processing the response went wrong. Google Cloud Test Lab – and why you should care about it.

We create an interface with 1 method that we annotate with @GET and the relative URL to the API endpoint of the REST API we want to query. isSuccess ()) {// print response body if unsuccessful try {System. Does your app fall over with it – or does it gracefully recover? However when I try applying this solution to my project I keep getting “Test running failed: Unable to find instrumentation info for: ComponentInfoTest running failed: Unable to find instrumentation info for: ComponentInfo{com.example.flavour1.demo.debug.test/android.support.test.runner.AndroidJUnitRunner}.

Really simple to test different HTTP Status Codes, Not much code needed to emulate the different responses, Difficult to dynamically create the responses. As you can see, the implementation that we mocked out previously is now being used in the test. This has been brought up before, but the problem is that you cannot trust the response body format of non-200 messages (actually you can't even trust 200s) because they could be coming from an intermediate source such as a load balancer, frontend HTTP server, proxy, captive web portal, etc. We then create a Retrofit instance, define the baseUrl, add GSON as the converter by passing GsonConverterFactory to the addConverterFactory method, and let Retrofit create the implementation of our API interface at compile time. Retrofit merupakan sebuah HTTP client yang mana kita dapat mengubah API yang dibutuhkan dalam satu class interface, sehingga pembuatan code menggunakan Retrofit dapat lebih jelas dan rapi. Create a synthetic successful response with an HTTP status code of code and body as the deserialized body. Found insideBuilder, the code in Listing 9.7 adds request/response logging to the Retrofit service for debug builds. Retrofit uses another library, OkHttp, ... accomplished by adding the following dependencies to build.gradle: The first dependency includes Retrofit itself, the second dependency includes the GSON converter library for (de-)serialization of JSON objects.

In case of response code < 200 || code >= 300 (OkHttp handles redirects and so on) RxJavaCallAdapter will emit onError () with HttpException, HttpException contains response with body and … This is the sample code for a number of httpbin.org API requests with GET and POST: You can find a IntelliJ project with the full source code at github.com/metachris/retrofit2-samples. You might want to do some other logic when there is an error but for simplicity, we will just display a retry button. In the code below, the service gets created and the activity asynchronously calls, You might wonder, how do we test that the retry button is properly shown when the server is down without turning the server off?

After trying out Retrofit 2, I have adjusted the previous sample and managed to achieve the same results (with some improvements ). response. A 200 response always has a payload, though an origin server MAY generate a payload body of zero length or empty payload. MVVM Architecture.

Click “Finish” to create the new project in Android Studio. It works fine however I noticed that the http status and statusCode are different. You can find the code here: With isSuccessFull we check if our response code is between 200 and 300 and if that’s the case we can retrieve our result from the response body.
