下記のGoogleマップのgecodingレスポンスのJSONレスポンスを検討してください。 5つの要素を持つaddress_componentsの配列で構成されています。 通常、開発者は最初のアイテム（インデックス0のアイテム）を使用して、とlocalityとformatted addressなどのアドレス要素を検索します。しかし、これは最良の選択肢ではありません。たとえば、この場合、2番目の項目は他の項目より記述的なアドレスです。同じ応答で異なる地方の同じアドレスがあることがあります。Google Map API：さまざまな "address_components"をgecoding結果で管理するにはどうすればよいですか？
どのようにすればいいですか（Android MapsではGoogle Maps APIを利用できますが、インデックスは0のアイテムではありませんが、選択肢の中から選択しますベストマッチ）？
それに、抽出した情報を一緒に細かい部分をもたらすために、異なるaddress_componentsのすべての要素を反復処理するために思っていたが、問題は、アドレスの矛盾をもたらすlocality状要素の同じタイプ有する異なるaddress_componentsにおける異なる情報のための情報であります情報の要素が異なるaddress_componentアイテムから集められたとき。 例として、以下のサンプルでは、2つの異なる都市ラベル（同じ地域内）である異なるlocality要素に2つの値شهر جدید اندیشهとKarajがあります。
