前の回答に続いて、はい、OkUrlFactory クラスは非推奨ではありません。しかし、HurlStack の代わりに OkHttp を使用して新しい HttpStack を定義することについて尋ねたので、この例に従うことができます。
dependencies {
implementation 'com.squareup.okhttp3:logging-interceptor:3.12.12'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.12.12'
implementation 'com.squareup.okhttp3:okhttp:3.12.12'
}
新しい HttpStack の場合、次のようになります。
