私はすぐにデータを記録し、ストリームに助けのためのJavaクラスを見つけました：ここjava classの使い方は？ Androidのスタジオ

私は自分のアプリケーションのために、このクラスを使用したいが、私は方法がわかりませんできます。私は主な活動から同時にデータを記録してストリーミングしたい。
EDIT 1：私はここでオブジェクトを呼び出す：任意の助け

ありがとう！
私はこのクラスを主なアクティビティに直接追加してもらえませんが、彼はうまくいきません。 – programmation1994
このクラスを 'MainActivity'の内部クラスとして定義することができます。' MainActivity'クラスの中でどのコードをコピーして使用するだけです。 'private'は' MainActivity'内でのみ使用できることを意味しています。それがあなたが好き/必要とするものなら、あなたはそれを行うことができます – magicleon
OK！しかし、私はこのクラスをどのようにインスタンス化できますか？他のJavaクラスのように – programmation1994
