android - React Native: External Library Dex Merger Error on an video conference API

I am working on building a video conferencing react-native app using agora.io API. When I am trying to run the app , it gives me a dex merger error.

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: /Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/0.jar, /Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/1.jar, /Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/2.jar,/Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/3.jar, /Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/4.jar, /Users/appleretina/Documents/GitHub/agoraVideoCall-master/android/app/build/intermediates/transforms/dexBuilder/debug/5.jar
...

I have already tried all the listed solutions for dex merger errors including deleting the build folders, setting multiDexEnabled to true, excluding the duplicated dependencies but none of the solutions worked in my case.

App.gradle :

android {

    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        applicationId "com.agoravideocall"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
        multiDexEnabled true


        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK

            include "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
    // applicationVariants are e.g. debug, release

    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:
            // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
            def versionCodes = ["armeabi-v7a":1, "x86":2]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }

        }
    }
}

dependencies {
    compile project(':react-native-agora')
    implementation project(':react-native-agora')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.facebook.react:react-native:+"  // From node_modules

}

build.gradle (agora video call)

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion

    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"


        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"


    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    implementation "com.facebook.react:react-native:+"
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}

How do I solve this issue.
