WebView webView = findViewById(R.id.webView);
webView.loadUrl("https://www.yahoo.co.jp/");

CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true); // Cookie受け入れを許可

WebView webView = findViewById(R.id.webView);

public class MyWebViewClient extends WebViewClient {

    @Override
    public void shouldOverrideUrlLoading(WebView view, String url) {
        // 次のURLを処理する

        super.onReceivedCookies(view, url, cookies);

        // Cookie を処理する
    }
}

WebView webView = findViewById(R.id.webView);
