}

override fun onDestroy() {

    mapView.onDestroy()
}

can anyone tell me why i m getting this error
Thanks in advance

SymbolManager が構築される MainActivity.kt:51 から始め、次に AnnotationManager.java:87 と、MapChangeReceiver.java に示されている onDidFinishLoadingStyle コールバックを追跡します。示されているスタイル読み込みフローで BootstrapMethodError を再現します。原因を特定し、検証済みの解決策を文書化できれば完了です。
