Could not find io.reactivex.rxjava2:rxandroid:2.2.20

Question

This is my project and I am trying to use this rxjava library. At the beginning, I added the required dependencies it is being synced without any fault but when I rebuilt the project it did not work. Here is my build gradle:

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'androidx.navigation.safeargs.kotlin'
    id 'kotlin-kapt'
    id 'kotlin-android'
}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.cerentekin.countrylist"
        minSdk 23
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    dataBinding {
        enabled = true
    }


    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }


}

dependencies {
    def lifeCycleExtensionVersion = '1.1.1'
    def supportVersion = '28.0.0'
    def retrofitVersion = '2.9.0'
    def glideVersion = '4.12.0'
    def rxJavaVersion = '2.2.20'
    def roomVersion = '2.4.2'
    def navVersion = '2.4.1'
    def preferencesVersion = '1.2.0'



    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.4.1'
    implementation 'com.google.android.material:material:1.5.0'

    androidTestImplementation 'androidx.test.ext:junit:1.1.3'

    implementation "com.squareup.retrofit2:adapter-rxjava2:$retrofitVersion"

    implementation "com.github.bumptech.glide:glide:$glideVersion"

    implementation "io.reactivex.rxjava2:rxjava:$rxJavaVersion"
    implementation "io.reactivex.rxjava2:rxandroid:$rxJavaVersion"

    implementation "androidx.room:room-runtime:$roomVersion"
    implementation "androidx.legacy:legacy-support-v4:1.0.0"
    kapt "androidx.room:room-compiler:$roomVersion"
    implementation "androidx.room:room-ktx:$roomVersion"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.2"

    implementation "androidx.navigation:navigation-fragment-ktx:$navVersion"
    implementation "androidx.navigation:navigation-ui-ktx:$navVersion"

    implementation "androidx.preference:preference:$preferencesVersion-ktx"

    implementation "com.google.android.material:material:1.5.0"

}

I have tried rxjava library for the first time but the project is not being synced." Could not find io.reactivex.rxjava2:rxandroid:2.2.20. " it gives me this fault.

Answer 1

You're using the same version for rxjava and rxandroid, two different libraries

The latest rxandroid version is 2.1.1 not 2.2.20

You can check the latest versions of libraries that are uploaded to maven by searching the maven repository

For example the rxandroid2 versions can be found listed here
