    android/build.gradle

allprojects {
    repositories {
        ...
        // jcenter()
        def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public/'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }
        ...
    }
}

before rebuild run:

cd android && ./gradlew clean && cd ..

This also works for me

        // jcenter()
        def REPOSITORY_URL = "https://repo1.maven.org/maven2"
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }

and you can fix the problem without editing gradle.build ???
then there will be problems when updating react-native

I also solved this problem in version 0.68.2

import org.apache.tools.ant.taskdefs.condition.Os

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "31.0.0"
        minSdkVersion = 21
        compileSdkVersion = 31
        targetSdkVersion = 31

        if (System.properties['os.arch'] == "aarch64") {
            // For M1 Users we need to use the NDK 24 which added support for aarch64
            ndkVersion = "24.0.8215888"
        } else {
            // Otherwise we default to the side-by-side NDK version from AGP.
            ndkVersion = "21.4.7075529"
        }
    }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
       classpath("com.android.tools.build:gradle:7.0.4")
       classpath("com.facebook.react:react-native-gradle-plugin")
       classpath("de.undercouch:gradle-download-task:4.1.2")
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url "https://maven.aliyun.com/repository/gradle-plugin" }
        maven { url("$rootDir/../node_modules/react-native/android") }
        maven { url("$rootDir/../node_modules/jsc-android/dist") }
        maven { url "https://www.jitpack.io" }
        mavenCentral()
        google()

        def REPOSITORY_URL = 'https://maven.aliyun.com/repository/public'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }
        mavenLocal()
    }
}
