I've found a much better option to auto increment your app versioning and auto renaming when you generate an apk / aab. Solution as below (do remember to create "version.properties" file on your root folder:

android {
     ...
     ...
    Properties versionProps = new Properties()
    def versionPropsFile = file("${project.rootDir}/version.properties")
    versionProps.load(new FileInputStream(versionPropsFile))
    def value = 0
    def runTasks = gradle.startParameter.taskNames
    if ('assemble' in runTasks || 'assembleRelease' in runTasks) {
        value = 1
    }
    def versionMajor = 1
    def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
    def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
    def versionNumber = versionProps['VERSION_NUMBER'].toInteger() + value
    versionProps['VERSION_PATCH'] = versionPatch.toString()
    versionProps['VERSION_BUILD'] = versionBuild.toString()
    versionProps['VERSION_NUMBER'] = versionNumber.toString()
    versionProps.store(versionPropsFile.newWriter(), null)

    defaultConfig {
    applicationId "com.your.applicationname"
    versionCode versionNumber
    versionName "${versionMajor}.${versionPatch}.${versionBuild}(${versionNumber})"
    archivesBaseName = versionName
    minSdkVersion 26
    targetSdkVersion 29
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    signingConfig signingConfigs.release
    setProperty("archivesBaseName","${applicationId}-v${versionName}")

    ...
}
