Android如何为第三方库共享webview cookies

public class CustomWebViewClient extends WebViewClient {
    private Context context;

    public CustomWebViewClient(Context context) {
        this.context = context;
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        CookieManager cookieManager = CookieManager.getInstance();
        String cookies = cookieManager.getCookie(request.getUrl().toString());

        SharedPreferences sharedPreferences = context.getSharedPreferences("WebViewCookies", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString("cookies", cookies);
        editor.apply();

        return super.shouldOverrideUrlLoading(view, request);
    }
}

WebView webView = findViewById(R.id.webView);
CookieManager cookieManager = CookieManager.getInstance();

SharedPreferences sharedPreferences = getSharedPreferences("WebViewCookies", Context.MODE_PRIVATE);
String cookies = sharedPreferences.getString("cookies", "");

cookieManager.setCookie(url, cookies);

webView.setWebViewClient(new CustomWebViewClient(this));
webView.loadUrl(url);
