Change this file (..\platforms\android\build.gradle)

defaultConfig {


    versionCode cdvVersionCode ?: new BigInteger("" + privateHelpers.extractIntFromManifest("versionCode"))
    applicationId privateHelpers.extractStringFromManifest("package")

    if (cdvMinSdkVersion != null) {
        minSdkVersion cdvMinSdkVersion
    }
}

to this

defaultConfig {

      minSdkVersion 21
   targetSdkVersion 26
    multiDexEnabled true

    versionCode cdvVersionCode ?: new BigInteger("" + privateHelpers.extractIntFromManifest("versionCode"))
    applicationId privateHelpers.extractStringFromManifest("package")

    if (cdvMinSdkVersion != null) {
        minSdkVersion cdvMinSdkVersion
    }
}
