は、私はそれがandroid.support.v4であるためisDeviceProtectedStorageあると思いました。 content.ContextCompatはAPI 24以降でのみ追加されました。しかし、Android 7で新しいデバイスを使用しても、同じメッセージが表示されます。

なぜメソッドが見つからないのですか？私はいくつかのライブラリをインストールできなかったのでですか？

Answer 1

Androidデベロッパーのドキュメントによると、DeviceProtectedStorageは24.0.0で追加されました。あなたは、この言及したAPIのバージョン以下のアプリを実行している場合は、それ

if (Build.VERSION.SDK_INT >= 24){ 
    //TODO: Do your stuff here. 
}
