Retrofit different domains using

Question

I use the retrofit library for the Android network operation. I have two domain addresses. I store the addresses with SharedPreferences. How can I use different endpoints.

for example:

www.mehmet.com/api/list
ww.deniz.com/api/list
www......
www.....

Code:

public class ptsApi {

    public static String BASE_URL = "";
    private static ptsApi instance;
    private ptsService ptsService;

    private ptsApi(Context c) {
        SharedPreferences sharedpreferences =  c.getSharedPreferences("loginPref", Context.MODE_PRIVATE);
        String BASE_URL = sharedpreferences.getString("api","").toString();

        final Gson gson =
                new GsonBuilder().
                        setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
                        .setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")
                        .create();

        final Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();
        ptsService = retrofit.create(ptsService.class);
    }

    public static ptsApi getInstance(Context c) {
        if (instance == null) {
            instance = new ptsApi(c);
        }
        return instance;
    }


    public Observable<SearchModel> getSearch(@NonNull String plate) {
        return ptsService.searchData(plate);
    }

You can try this.

public class ptsApi {
    enum TYPE {
        MEHMENT, DENIZ

    }

    private static ptsApi instance;
    private ptsService ptsService;

    private ptsApi(Context c, TYPE type) {
        final String BASE_URL = getEndpoint(type);

        final Gson gson =
                new GsonBuilder().
                        setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
                        .setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")
                        .create();

        final Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();
        ptsService = retrofit.create(ptsService.class);
    }

    public static ptsApi getInstance(Context c, TYPE type) {
        if (instance == null) {
            instance = new ptsApi(c, type);
        }
        return instance;
    }


    public Observable<SearchModel> getSearch(@NonNull String plate) {
        return ptsService.searchData(plate);
    }

    public String getEndpoint(TYPE type) {
        SharedPreferences sharedpreferences = c.getSharedPreferences("loginPref", Context.MODE_PRIVATE);
        switch (type) {
            case MEHMENT:
                return sharedpreferences.getString("mehmentApi","").toString();
            case DENIZ:
                return sharedpreferences.getString("denizApi","").toString();
            default:
                return "your default";
        }
    }
}

or you can create some method like

public static ptsApi getMehmetInstance(Context c) {
    if (instance == null) {
        instance = new ptsApi(c, MEHMENT);
    }
    return instance;
}
public static ptsApi getDenizInstance(Context c) {
    if (instance == null) {
        instance = new ptsApi(c, DENIZ);
    }
    return instance;
}
