I am new to Retrofit Library. I am working on an app in which I've to make multiple API calls, but this problem sticks me when I tried to make my first API Call...
I am facing the issue that whenever I used to call retrofit's Asynchronous call method then the functionality inside onResponse method is running 2 times...
This is my code when I am calling the API call asynchronously...
final ApiModule apiService = ApiServiceGenerator.createService(ApiModule.class);
Call <ConfigResponse> call = apiService.getConfig();
call.enqueue(new Callback<ConfigResponse>() {
@Override
public void onResponse(Call<ConfigResponse> call, Response<ConfigResponse> response) {
try {
if (response.isSuccessful()) {
Log.e("MyTag", "This is running");
}
} catch(Exception e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call<ConfigResponse> call, Throwable t) {
e.printStackTrace();
}
});
As soon as I run the App on the device and when I see my android studio's logger, its is showing me the log message as -
E/MyTag: This is running
E/MyTag: This is running
It seems here that its running for 2 times..!!
I cannot understand that why is it running 2 times. Please help me out with this...
Just for more help... I've implemented my code like this.
ApiModule Interface (where I defined my API Call URLs)
public abstract interface ApiModule {
@GET("config")
Call<ConfigResponse> getConfig();
}
ApiServiceGenerator goes like this -
public class ApiServiceGenerator {
public static final String API_BASE_URL = "https://www.example.com/";
private static OkHttpClient httpClient = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
@Override
public okhttp3.Response intercept(Chain chain) throws IOException {
Request newRequest = chain.request().newBuilder().addHeader("App-Secret", "some-secret-key").build();
return chain.proceed(newRequest);
}
})
.addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)) // Just For logging
.readTimeout(60, TimeUnit.SECONDS)
.connectTimeout(60, TimeUnit.SECONDS)
.build();
Gson gson = new GsonBuilder()
.registerTypeAdapterFactory(new ArrayAdapterFactory())
.create();
private static Retrofit.Builder builder =
new Retrofit.Builder()
.baseUrl(API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create(new GsonBuilder().registerTypeAdapterFactory(new ArrayAdapterFactory()).create()));
public static <S> S createService(Class<S> serviceClass) {
Retrofit retrofit = builder.client(httpClient).build();
return retrofit.create(serviceClass);
}
public static Retrofit retrofit() { // For Error Handing when non-OK response is received from Server
OkHttpClient httpClient = new OkHttpClient.Builder().build();
OkHttpClient client = httpClient;
return builder.client(client).build();
}
}
Finally I resolved my problem.. Its not the problem of the Retrofit library..!!
Actually its my bad. I am opening the fragment twice (which I don't know before answering this question)... That's why the code inside the fragment is running twice which makes me think as retrofit response is running twice...
