Page Renaming or Moving: If the webpage you’re trying to access has been renamed or moved to a different location, the old URL will result in a 404 error.
Broken Links: If the page contains broken links or references to resources that no longer exist, a 404 error might appear.
Server Issues: Sometimes, the server hosting the webpage might be down or experiencing technical problems, leading to a 404 error.

Steps to Handle 404 Errors in Android WebView

Dealing with 404 errors requires a systematic approach to ensure a seamless user experience. Here’s a step-by-step guide to help you tackle this issue effectively:

Double-Check the URL: Before anything else, verify that the URL you’re trying to load is correct. Check for any typos or missing characters.
Use WebViewClient: Implement a WebViewClient and override the onReceivedError method. This allows you to intercept errors, including 404 errors, and take appropriate action.
Display a User-Friendly Message: Instead of presenting the raw 404 error message, show a user-friendly message that explains the situation and suggests what the user can do next.
Offer Navigation Options: Include navigation options within the error message, such as a “Go Back” button or links to relevant sections of your app.
Custom Error Pages: Create custom error pages within your app’s assets. Load these pages whenever a 404 error occurs, maintaining the app’s branding and design.
Check Internet Connection: Before attempting to load a URL, ensure that the device has a stable internet connection. Prompt the user to check their network if a connection issue is detected.
Implement Retry Logic: In case of temporary network issues, provide users with the option to retry loading the page.
