This is code below when u click to set default url as home page :
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("URL","http"//sample.com");
editor.apply();
When u set url to browser do this :
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String url= preferences.getString("URL","");
if(!name.equalsIgnoreCase(""))
{
//set url in broswer u will always get as last setted home page url

How to add Network Error message in WebView if there's no internet access

I'm having a problem with my WebView-App.
I want to add a "Connection-check" on startup that's popping up an error when no Internet-connection is aviable or the WebView is timed out. I can't get it done by myself because I'm new in Android-programming.
I also want to add an options-menu where i can reload the actual page.
Hope someone can help me...
The actual code:
package com.sabithpkcmnr.webviewmaster;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.Uri;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.webkit.DownloadListener;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ImageView;
import android.widget.ProgressBar;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
ImageView superImageView;
ProgressBar superProgressBar;
WebView superWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setDisplayShowHomeEnabled(true);
superImageView = findViewById(R.id.myImageView);
superProgressBar = findViewById(R.id.myProgressBar);
superWebView = findViewById(R.id.myWebView);
superProgressBar.setMax(100);
superWebView.loadUrl("http://google.com");
superWebView.getSettings().setJavaScriptEnabled(true);
superWebView.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);
}
});
superWebView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
superProgressBar.setProgress(newProgress);
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);

}

super.onReceivedIcon(view, icon);
superImageView.setImageBitmap(icon);
}
});

break;
}
return true;
}
private void GoForward() {
if (superWebView.canGoForward()) {
superWebView.goForward();
} else {
Toast.makeText(this, "Can't go further!", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onBackPressed() {
if (superWebView.canGoBack()) {
superWebView.goBack();
} else {
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setTitle("(Exit?");
dialog.setMessage("Name has nothing to go back, so what next?");
dialog.setPositiveButton("EXIT ME", new DialogInterface.OnClickListener() {

Try below method by replacing your setWebViewClient,
superWebView= (WebView) findViewById(R.id.webView);
superWebView.setWebViewClient(new myWebClient());
superWebView.getSettings().setJavaScriptEnabled(true);
superWebView.loadUrl("LOAD_YOUR_URL");
superWebView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView webView, int errorCode, String description, String failingUrl) {
try {
webView.stopLoading();
} catch (Exception e) {
}
if (webView.canGoBack()) {
webView.goBack();
}
webView.loadUrl("about:blank");
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Error");
alertDialog.setMessage("Check your internet connection and try again.");
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "Try Again", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
startActivity(getIntent());
}
});
alertDialog.show();
super.onReceivedError(webView, errorCode, description, failingUrl);
}
});
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}

Below method can be used to check internet connection.
public static boolean checkInternetConnection(Context context) {
ConnectivityManager con_manager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
return (con_manager.getActiveNetworkInfo() != null
&& con_manager.getActiveNetworkInfo().isAvailable()
&& con_manager.getActiveNetworkInfo().isConnected());
}
you can check internet connection before loading url in webview.
Check below code snippet.
if (checkInternetConnection(this)) {
superWebView.loadUrl("http://google.com");
}else{
Toast.makeText(getApplicationContext(), "No Internet!", Toast.LENGTH_SHORT).show();
}

How to Load Cache Page in Webview

I have Cache Manifest applied on HTML Page.
On Chrome Browser when Internet connection goes off, it redirects to cache mode.
Well, this is not the case with Android-Webview. It gives following error:
Webpage could not be loaded
net:ERR_NAME_NOT_RESOLVED
Have gone through various resources but none seems to help.
Below is the code am using:

Just include enableHTML5AppCache()
private void enableHTML5AppCache() {
mWebview.getSettings().setDomStorageEnabled(true);
mWebview.getSettings().setAppCachePath("/data/data/" + getPackageName() + "/cache");
mWebview.getSettings().setAppCacheEnabled(true);
mWebview.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}

mWebview.getSettings().setCacheMode( WebSettings.LOAD_CACHE_ELSE_NETWORK)
This will tell the WebView to load the page from cache, but if it needs anything that isn't in the cache, it looks to the network, and when you have no connection, it will just give you the "page could not be loaded error." This is because sadly not everything is stored in the cache and even with this setting, you will notice the browser using the network.
Use WebSettings.LOAD_CACHE_ONLY
mWebview.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ONLY);

Change this line:
mWebview.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
To:
mWebview.getSettings().setCacheMode( WebSettings.LOAD_CACHE_ELSE_NETWORK)

2021 update things have changed : Deprecated
The Application Cache API is deprecated and this method will become a no-op on all Android versions once support is removed in Chromium. Consider using Service Workers instead. See https://web.dev/appcache-removal/ for more information.
Read about service workers instead :) Happy Coding :P

}
I'm beginner so please explain kindly with simple instruction and thanks

Try this

Android Webview loading other URLs

I have a webview, yes i do. :)
Anyway, I load my main URL fine, but i need to load another url programmatically at some point. The problem is that it somewhat opens another webview, and I know this because when I exit the app using finish() method, the webview with the latter url closes, but another webview stays open. What should I do? Should i call destroy webview or something else?
I just load them URLs using webview.loadUrl(url here) method.

Should I also include manifest? Thanks in advance.

Put this in your web Activity :
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Then set :
your_webview.setWebViewClient(new MyWebViewClient());
Hope this will help you

Without the necessary code I have to assume this is what you need to add to your implementation.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webview.loadUrl(url);
return true;
}

Shouldoverrideurlloading method in android

I am running into trouble in shouldoverrideurlloading method, wherein the URL being overridden is not being shown. Instead, a blank white screen is coming up, and Logcat shows no errors. I have provided code below . WHere am I making a mistake? Please advise
package com.example.webviewkm;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.Menu;
import android.view.View;
import android.webkit.HttpAuthHandler;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import android.webkit.SslErrorHandler;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView webView = (WebView) findViewById(R.id.MyWebView);
webView.setInitialScale(67);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.setVerticalScrollBarEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedLoginRequest(WebView view, String realm,
String account, String args) {
System.err.println(realm);
System.err.println(account);
System.out.println(args); }
#Override
public void onReceivedError( WebView view, int errorCode, String description, String failingUrl ) {
Toast.makeText(view.getContext(), "Unknown Error", Toast.LENGTH_LONG).show();
System.err.println(errorCode + " - " + description + "-" + failingUrl);
}
#Override
public void onReceivedSslError( WebView view, SslErrorHandler handler, SslError error ) {
System.err.println("SSL ERROR");
handler.proceed();
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent intent = new Intent(MainActivity.this, MainActivity.class);
intent.putExtra("url", url);
startActivity(intent);
return true;
}
#Override
public void onReceivedHttpAuthRequest(WebView view, final HttpAuthHandler handler, final String host,
String realm) {
System.err.println("HTTP auth request");
final SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(MainActivity.this);
if (handler.useHttpAuthUsernamePassword()) {
if (preferences.contains("username")) {
handler.proceed(preferences.getString("username", null), preferences.getString("password", null));
return;
}
}
new Dialog(MainActivity.this){
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.credentials);
final EditText userName = (EditText) findViewById(R.id.UserName);
final EditText password = (EditText) findViewById(R.id.Password);
userName.setText(preferences.getString("username", ""));
password.setText(preferences.getString("password", ""));
Button button = (Button) findViewById(R.id.GoButton);
button.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v) {
String userName2 = userName.getText().toString();
String password2 = password.getText().toString();
Editor edit = preferences.edit();
edit.putString("username", userName2);
edit.putString("password", password2);
edit.commit();
handler.proceed(userName2, password2);
dismiss();
}});
}
}.show();
}
});
String url;
if (getIntent().hasExtra("url")) {
url = getIntent().getStringExtra("url");
} else {
url = "https://kee.mahindrasatyam.com/_layouts/mobile/mobilesearch.aspx";
}
webView.loadUrl(url);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
Intent intent = new Intent(MainActivity.this, MainActivity.class);
startActivity(intent);
return true;
}
}

In your Code pasted below in the method shouldOverrideUrlLoading,
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Intent intent = new Intent(MainActivity.this, MainActivity.class);
intent.putExtra("url", url);
startActivity(intent);
return true;
}
You are just Starting the same Activity and you are passing the url as intent extra ,this will not load the url in webview neither it will give you an error , and if you are intending to load the url in the webview use
webView.loadUrl(url) in shouldOverrideUrlLoading method.
