RxJava:

https://github.com/ReactiveX/RxAndroid

https://github.com/ReactiveX/RxJava

官网：reactivex.io

RxJava是响应式编程(Reactive Extensions)的java实现，它基于观察者模式的实现了异步编程接口。

Rxjava 3.0的一些改变：官方Wiki；https://github.com/ReactiveX/RxJava/wiki/What’s-different-in-3.0

Rxjava 3.x 文档可以在官方javadoc中找到: RxJava Javadoc 3.1.1

1，Retrofit + RxJava3组合使用
首先要引入依赖

implementation “io.reactivex.rxjava3:rxjava:3.0.0”
implementation ‘io.reactivex:rxandroid:1.2.1’
implementation ‘com.squareup.retrofit2:retrofit:2.7.0’
implementation ‘com.squareup.retrofit2:adapter-rxjava3:2.9.0’
相关配置module下的build.gradle

android {

compileOptions {

sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
注意Retrofit和RxJava组合使用时，Retrofit中使用的rxjava适配器（adapter-rxjava3）要和RxJava版本（io.reactivex.rxjava3:rxjava:3.0.0）一致；如本例都是使用的时3.0；关于先前Rerotfit没有Rxjava3.0适配器问题；android – Which rxjava3 retrofit-adapter should we use for Rxjava3 – Stack Overflow

android使用：

allprojects {
    repositories {
        maven { url "https://oss.jfrog.org/libs-snapshot" }
    }
}

dependencies {
    implementation 'io.reactivex.rxjava3:rxandroid:3.0.0'
    // Because RxAndroid releases are few and far between, it is recommended you also
    // explicitly depend on RxJava's latest version for bug fixes and new features.
    // (see https://github.com/ReactiveX/RxJava/releases for latest 3.x.x version)
    implementation 'io.reactivex.rxjava3:rxjava:3.0.0'
}

}

OKHttp:

https://github.com/square/okhttp

官网： OkHttp

dependencies {

// define a BOM and its version

implementation(platform(“com.squareup.okhttp3:okhttp-bom:4.9.0”))

// define any required OkHttp artifacts without version implementation(“com.squareup.okhttp3:okhttp”)

implementation(“com.squareup.okhttp3:logging-interceptor”)
