私はこれを使用して、autocompletetextviewのアドレスを提案として取得しました。 Google Places APIを有効にしてAndroid Keyを生成しました。しかし、私はこのエラーThis IP, site or mobile application is not authorized to use this API key. Request received from IP address <IP>, with empty refererを取得するアプリを実行するとき。私が間違っていることがありますか？この点に関して誰かが私を助けることができれば、それは素晴らしいことでしょう。ありがとう。Google places API認証エラー
