android - Androidでカスタムブラウザからアプリに移動するには?

Question

PayU 統合のためにアプリにカスタム ブラウザを統合しました。PayU URL ( https://secure.payu.in/_payment ) にパラメーターを送信していません。サーバー側でこれを行っています（PayUにパラメーターを送信しています）。ブラウザのカスタマイズだけが必要なので、これを使用しています。これは私には問題なく機能していますが、支払いが成功した後、空の白い画面が表示されます。この白い空の画面の後にアプリに移動する方法。

カスタム ブラウザの URL を取得するにはどうすればよいですか?
