私はライブラリを介して許可を受け取りましたLet、しかし私はまだAndroidアプリで経度と緯度を取得できません。私はGPS_Service.javaというサービスを使用しています。また、私の許可が問題ではないことを100％保証しているわけではありません。 GPS_Serviceのgoogle APIへの呼び出しには、拒否される可能性のあるアクセス許可が必要であるという警告が下線付きで表示されます。それは第三者の図書館でさえも遠ざかるでしょうか？私のデバイスでは、アプリケーションにロケーション権限が有効になっているため、これはまだ問題になりますか？ここ lastKnownLocationを使用すると、緯度と経度は常に0.0が返されます
