I am currently researching on this online. I have got no helpful solution.

Here is the dependencies from my build.gradle file:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "androidx.appcompat:appcompat:$androidxAppCompatVersion"
    implementation project(':capacitor-android')
    testImplementation "junit:junit:$junitVersion"
    androidTestImplementation "androidx.test.ext:junit:$androidxJunitVersion"
    androidTestImplementation "androidx.test.espresso:espresso-core:$androidxEspressoCoreVersion"
    implementation project(':capacitor-cordova-android-plugins')
    implementation 'com.google.android.gms:play-services-location:18.0.0'

    def appCenterSdkVersion = '4.3.1'
    implementation "com.microsoft.appcenter:appcenter-analytics:${appCenterSdkVersion}"
}
