アクティビティから戻った後にGoogleMap( ) オブジェクトの状態を復元しようとすると、アプリが一貫してクラッシュします。カスタム サポート ライブラリ v4 ( ) にあり、それ自体が( ) に埋め込まれています。これらのコンポーネントのセットアップは正常です。私のデバイスは、プッシュ時にすべての を破棄するように開発者が構成しています。mapViewmapViewFragmentMyFragmentAppCompatActivityMyActivityActivity
別の をプッシュしてポップするとActivity、 myFragmentのonCreateView(LayoutInflater, ViewGroup, Bundle state)メソッドが呼び出され、クラッシュします
mapView.onCreate(state);
下部にトレースを生成します。
が の場合、最初の作成時にクラッシュは発生しません。クラッシュは、MultiDex または Proguard を有効または無効にする (私が見つけた) 組み合わせによって解決されません。statenull
実際、私ができることは、Instant Run を有効にして Android Studio から直接実行することだけです。この場合、すべて問題ありません。Instant Run を無効にして Android Studio から実行すると、クラッシュが発生します。
アップデート：
先週、Google は Android Build Tools v5.0.1 と Google Play Services v10.0 をリリースしました。更新後、この問題は解消されたようです。ただし、他のアイデアが現れるかどうかを確認するために、この質問は開いたままにします。以下の Aлекс のアイデアは、私がとにかく試すことができる良いアイデアです。
