Features

Features of Retrofit and OkHttp
Method Chaining by RxJava
Support calling in both Kotlin and Java
Automatically invoke response callback on Android Main Thread while HTTP networking on IO Thread

Usage

There are two samples, one is in Kotlin and another in Java.

Quick Glance Usage

Kotlin

// get
apiService.get()
        .compose(MyTransformer<Response<MyResponse>, MyResponse>())
        .map { it.data }
        .subscribeWith(object : ToastObserver<String>(context){
            override fun onNext(t: String) {
                // do something when it is successful
            }

            override fun onStart() {
                super.onStart()
                // do something when it is started
            }

            override fun onError(t: Throwable) {
                super.onError(t)
                // do something when it is failed
            }

            override fun onComplete() {
                super.onComplete()
                // do something when it is completed
            }

            override fun onTokenInvalid(e: TokenInvalidException) {
                // do something when token is invalid
            }
        })

Java

// get
apiService.get()
        .compose(new MyTransformer <>())
        .map(response -> response.data)
        .subscribeWith(new ToastObserver<String>(context) {
            @Override
            public void onNext(String s) {
                // do something when it is successful
            }

            @Override
            protected void onStart() {
                super.onStart();
                // do something when it is started
            }

            @Override
            public void onError(@NotNull Throwable t) {
                super.onError(t);
                // do something when it is failed
            }

            @Override
            public void onComplete() {
                super.onComplete();
                // do something when it is completed
            }

            @Override
            public void onTokenInvalid(@NotNull TokenInvalidException e) {
                // do something when token is invalid
            }
        });

Configuration

You can make common configuration in Application or MainActivity.

Kotlin

Base url is necessary

OkNet.apply {
    baseUrl = BASE_URL
}

Or custom RetrofitBuilder

OkNet.apply {
    retrofitBuilder = RetrofitBuilder(baseUrl = BASE_URL)
            .isLoggingEnable(BuildConfig.DEBUG)
            .monitor(MyMonitor)
            .clientBuilder(MyOkHttpClientBuilder)
            .interceptors(MyInterceptor)
            .callAdapterFactories(MyCallAdapterFactory)
            .converterFactories(MyConverterFactory)
            .timeout(timeout)
}

Java

Base url is necessary

OkNet.setBaseUrl(BASE_URL);

Or custom RetrofitBuilder

OkNet.setRetrofitBuilder(new RetrofitBuilder(BASE_URL)
        .isLoggingEnable(BuildConfig.DEBUG)
        .monitor(MyMonitor)
        .clientBuilder(MyOkHttpClientBuilder)
        .interceptors(MyInterceptor)
        .callAdapterFactories(MyCallAdapterFactory)
        .converterFactories(MyConverterFactory)
        .timeout(timeout);

Response

Custom response must extends BaseResponse

Kotlin

@Keep
data class MyResponse(
        @SerializedName("others") val others: String?) : BaseResponse<MyResponseData>()

Java

@Keep
public class MyResponse extends BaseResponse<MyResponseData> {
    @SerializedName("others")
    public String others;
}

Service

Service must be an interface, and you should define your apis in service.

Kotlin

interface ApiService {
    @GET("list")
    fun getList(@Query("start") start: Int = 0,
                @Query("count") count: Int = 10): Observable<Response<MyResponse>>

    @FormUrlEncoded
    @POST("list")
    fun postList(@Field("start") start: Int = 0,
                 @Field("count") count: Int = 10): Observable<Response<MyResponse>>

    @GET("subject/{id}")
    fun getSubject(@Path("id") id: Long): Observable<Response<MyResponse>>
}

Java

public interface ApiService {
    @GET("list")
    Observable<Response<MyResponse>> getList(@Query("start") int start,
                                             @Query("count") int count);

    @FormUrlEncoded
    @POST("list")
    Observable<Response<MyResponse>> postList(@Field("start") int start,
                                              @Field("count") int count);

    @GET("subject/{id}")
    Observable<Response<MyResponse>> getSubject(@Path("id") long id);
}

Transformer

If there are some common business errors to handle, you can do it in your own Transformer witch extends one of BaseObservableTransformer, BaseFlowableTransformer, BaseMaybeTransformer, or BaseSingleTransformer.

Kotlin

class MyTransformer<T : Response<R>, R : BaseResponse<*>> : BaseObservableTransformer<T, R>() {
    override fun isTokenInvalid(r: R): Boolean = false

    override fun isResponseError(r: R): Boolean = r.code != null || r.msg != null
}

Java

public class DefaultTransformer<T extends Response<R>, R extends BaseResponse<?>> extends BaseObservableTransformer<T, R> {
    @Override
    public boolean isTokenInvalid(R r) {
        return false;
    }

    @Override
    public boolean isResponseError(R r) {
        return r.getCode() != null && r.getCode() != -1 || r.getMsg() != null;
    }
}

Subscriber

You can define your own Subscriber or Observer to handle reponse, witch extends BaseSubscriber or BaseObserver. Also you can extends ToastSubscriber or ToastObserver witch toast error message, so you can only care for your successful response.

Proguard

A Proguard configuration is provided as part of the library, so you don’t need to add any specific rules to your Proguard configuration.

Contribution

Issues are welcome. Please add a screenshot of bug and code snippet.
Pull requests are welcome. If you want to change API or making something big better to create issue and discuss it first.
