Android受信位置更新のチュートリアルに従おうとしています。サンプル コードはGithub にあります。
この行を除いてすべてが機能しています:
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
エラーをスローしていcannot resolve method requestLocationUpdates
ます。ドキュメントには何も表示されませんが、私は Android を初めて使用するので、何か不足している可能性があります :)。
これが完全なコードです。私が間違っているアイデアはありますか?ありがとう!
