In my app i am using webview to display some web data, i want to implement a functionality where if a user clicks on any link a new screen (activity) will open and url's data will be displayed in that activity's webview. i have tried setting a webview client to webview and overriding its onPageStarted,shouldOverrideUrlLoading methods but they all open the url within the same screen.
Here is my code
webview.loadData(html, "text/html; charset=utf-8", "UTF-8");
webview.setWebViewClient(webViewClient);
}
WebViewClient webViewClient = new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
if (url.startsWith("http://")) {
Intent intent = new Intent(FirstActivity.this, WebActivity.class);
intent.putExtra("url", url);
startActivity(intent);
}
}
#Override
public void onPageFinished(WebView view, String url) {
}
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return false;
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
};
How this can be implemented? any help will be appreciated
Try this:
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("http://")) {
Intent intent = new Intent(FirstActivity.this, WebActivity.class);
intent.putExtra("url", url);
startActivity(intent);
return true;
}
return false;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
String url = request.getUrl().toString();
if (url.startsWith("http://")) {
Intent intent = new Intent(FirstActivity.this, WebActivity.class);
intent.putExtra("url", url);
startActivity(intent);
return true;
}
return false;
}
Try this. But you first need to set a start website like google.com
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
private WebView view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = (WebView) this.findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setDomStorageEnabled(true);
view.setWebViewClient(new MyBrowser());
view.loadUrl("[YOUR_WEBSITE]"); //try js alert
view.setWebChromeClient(new WebChromeClient()); // adding js alert support
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:") || url.startsWith("sms:") || url.startsWith("smsto:") || url.startsWith("mailto:") || url.startsWith("mms:") || url.startsWith("mmsto:") || url.startsWith("market:")) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
else {
view.loadUrl(url);
return true;
}
}
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && view.canGoBack()) {
view.goBack(); //method goback()
return true;
}
return super.onKeyDown(keyCode, event);
}
}
If links are external to the site, you could do something like this:
webview.setWebViewClient(new LinkExtWebViewClient());
And then:
public class LinkExtWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith(" if your site is www.myurl.com, here you have to insert 'myurl.com' ")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
Let me know if it works :)

I am trying android webview but whatsapps button give an error when i want to connect whatsapp app in my mobile, the error is like - ERR_UNKNOWN_URI_SCHEME,
below are my code, please help me-
public class MainActivity extends AppCompatActivity {
private WebView mywebView;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mywebView.setWebViewClient(new WebViewClient());
mywebView.loadUrl("https://royalahm.com");
WebSettings webSettings=mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
}
public class mywebClient extends WebViewClient{

}
else{
super.onBackPressed();
}
}
}
Try This :
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){

try {
// Otherwise allow the OS to handle things like tel, mailto, etc.
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
}catch (Exception e){
Log.i("IvaExc",e.toString());

I am doing webview in android in which I am calling a website link in that website I am calling web.whatsapp.com link. Now this link is working good in desktop as well as mobile view while the same link if I open in webview then showing error i.e. web page is not available for more clear let see the error image
Here is the code of webview android
public class MainActivity extends AppCompatActivity {
WebView webView;
ProgressBar bar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webView2);
bar =(ProgressBar) findViewById(R.id.progressBar2);
webView.setWebViewClient(new myWebClient());
webView.loadUrl("http://.../");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new myWebClient());
}
public class myWebClient extends WebViewClient{
#Override
public void onPageFinished(WebView view, String url) {
bar.setVisibility(View.GONE);
view.setVisibility(webView.VISIBLE);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
bar.setVisibility(View.VISIBLE);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
bar.setVisibility(View.GONE);
return super.shouldOverrideUrlLoading(view, url);
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()){
webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Try to override shouldOverrideUrlLoading in your web client and use code given below .
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
boolean overrideUrlLoading = false;
if (url != null && url.startsWith("whatsapp://")) {
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
overrideUrlLoading = true;
} else {
view.loadUrl(url);
}
return overrideUrlLoading;
}

Thanks to all helpers.

You have to create a subclass of WebViewClient and override mailto URL loading. Example:
public class MyWebViewClient extends WebViewClient {
private final WeakReference<Activity> mActivityRef;
public MyWebViewClient(Activity activity) {
mActivityRef = new WeakReference<Activity>(activity);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("mailto:")) {
final Activity activity = mActivityRef.get();
if (activity != null) {
MailTo mt = MailTo.parse(url);
Intent i = newEmailIntent(activity, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc());
activity.startActivity(i);
view.reload();
return true;
}
} else {
view.loadUrl(url);
}
return true;
}
private Intent newEmailIntent(Context context, String address, String subject, String body, String cc) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { address });
intent.putExtra(Intent.EXTRA_TEXT, body);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_CC, cc);
intent.setType("message/rfc822");
return intent;
}
}
Then you have to set this custom WebViewClient to your WabView:
webView.setWebViewClient(new MyWebViewClient(activity);
You should update your's WebViewClient with the following:
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
proceedUrl(view, Uri.parse(url))
return true;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
proceedUrl(view, request.getUrl());
return true;
}
private void proceedUrl(View view, Uri uri){
if (uri.toString().startsWith("mailto:")) {
startActivity(new Intent(Intent.ACTION_SENDTO, uri));
} else if (uri.toString().startsWith("tel:")) {
startActivity(new Intent(Intent.ACTION_DIAL, uri));
} else {
view.loadUrl(uri.toString());
}
}
Note : - After Android Nougat shouldOverrideUrlLoading is Deprecated
You need to use shouldOverrideUrlLoading along with shouldOverrideUrlLoading for better support.
Also, you might want to check if URL have mailto: or tel:, which are used in HTML5 to trigger mail client and phone dial respectively.
A complete solution will look like this now
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("mailto:")) {
//Handle mail Urls
startActivity(new Intent(Intent.ACTION_SENDTO, Uri.parse(url)));
} else if (url.startsWith("tel:")) {
//Handle telephony Urls
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
} else {
view.loadUrl(url);
}
return true;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
final Uri uri = request.getUrl();
if (uri.toString().startsWith("mailto:")) {
//Handle mail Urls
startActivity(new Intent(Intent.ACTION_SENDTO, uri));
} else if (uri.toString().startsWith("tel:")) {
//Handle telephony Urls
startActivity(new Intent(Intent.ACTION_DIAL, uri));
} else {
//Handle Web Urls
view.loadUrl(uri.toString());
}
return true;
}
I have a telephone link on my webview app: tel:062123658 but when I click on it I get webpage not found.
This is my code:
public class FullscreenActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.loadUrl("http://www.mywebsite.nl");
webView.setVerticalScrollBarEnabled(false);
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL,
Uri.parse(url));
startActivity(intent);
}else if(url.startsWith("http:") || url.startsWith("https:")) {
view.loadUrl(url);
}
return true;
}
How can I fix this?
You should override a function in WebViewClient:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.loadData("Hello World, 317.456.2564 ", "text/html","utf-8");
//webView.loadUrl("http://www.techjini.com/contactus.html");
webView.setVerticalScrollBarEnabled(false);
}
class myWebClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL,
Uri.parse(url));
startActivity(intent);
}else if(url.startsWith("http:") || url.startsWith("https:")) {
view.loadUrl(url);
}
return true;
}
}
Try this way:
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL,
Uri.parse(url));
startActivity(intent);
}else if(url.startsWith("http:") || url.startsWith("https:")) {
view.loadUrl(url);
}
return true;
}
});
