Here's an example of how to load a URL and print from an Android app using Java:

import android.content.Context;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class UrlPrinter {

    private Context mContext;
    private WebView mWebView;

    public UrlPrinter(Context context) {
        mContext = context;
        mWebView = new WebView(mContext);
        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                // Load the URL in the webview
                view.loadUrl(url);
                return true;
            }
        });
    }

    public void printUrl(String url) {
        // Load the URL in the webview
        mWebView.loadUrl(url);

        // Print the web page
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
            mWebView.evaluateJavascript("(function() { window.print(); })();", null);
        } else {
            mWebView.loadUrl("javascript:window.print()");
        }
    }
}

To use this class in your Android app, you can create an instance of the UrlPrinter class and call the printUrl() method with the URL you want to print:

UrlPrinter urlPrinter = new UrlPrinter(this);
urlPrinter.printUrl("https://example.com");

Note: This example uses the WebView component to load and print the web page. Make sure to add the necessary permissions in your app's manifest file and handle any potential security risks associated with loading external URLs.

Here's another example of how to load a URL and print from an Android app using Java, but using a different approach that doesn't rely on the WebView component:

import android.content.Context;
import android.graphics.Bitmap;
import android.os.Handler;
import android.os.Looper;
import android.print.PrintAttributes;
import android.print.PrintDocumentAdapter;
import android.print.PrintJob;
import android.print.PrintManager;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import androidx.print.PrintHelper;

public class UrlPrinter {

    private Context mContext;

    public UrlPrinter(Context context) {
        mContext = context;
    }

    public void printUrl(String url) {
        // Create a WebView to load the URL
        WebView webView = new WebView(mContext);
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);

                // Print the web page
                PrintHelper printHelper = new PrintHelper(mContext);
                printHelper.setScaleMode(PrintHelper.SCALE_MODE_FIT);
                printHelper.printBitmap("Web page", view.createPrintBitmap(), null);
            }

            @Override
            public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
                super.onReceivedError(view, request, error);
                // Handle any errors that occur while loading the URL
            }
        });
        webView.loadUrl(url);
    }
}

In this example, we're creating a WebView to load the URL, and using a WebViewClient to handle the web page loading events. When the web page finishes loading, we're using the PrintHelper class to print the page. Note that you'll need to replace mContext with the appropriate Context reference in your code.

To use this class in your Android app, you can create an instance of the UrlPrinter class and call the printUrl() method with the URL you want to print:

UrlPrinter urlPrinter = new UrlPrinter(this);
urlPrinter.printUrl("https://example.com");

Note: This example uses the PrintHelper class to print the web page. Make sure to add the necessary permissions in your app's manifest file and handle any potential security risks associated with loading external URLs.
