How can I open a web page from inside my app? - android

I've found an app's source code and it opens web pages using external browsers, like Chrome or others. I want to make it access those pages from inside the app, without using an external browser. I think that I should change the code below somehow, but I don't know how.
private class MyWebviewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("http://dmc.teiion.gr")) {
//open url contents in webview
return false;
} else {
//here open external links in external browser or app
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}

yourWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
}
});
Or change
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
to
view.loadUrl(url);

Open activity after clicking inside webview

How do we open an activity after clicking some specific link or button of a website which is from some website and open using webview?
Use shouldOverrideUrlLoading to give the host application a chance to take over the control when a new url is about to be loaded in the current WebView.
For more information shouldOverrideUrlLoading
Try this it will help you:
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals("url")) {
Intent intent = new Intent(contxt, YourActivity.class);
startActivity(intent);
return true; // Handle By application itself
} else {
view.loadUrl(url);
return true;
}
}
}

webview shouldOverrideUrlLoading multiple url

i'm trying to load two different url in a webview, but it seems something went wrong or maybe webview does not allow override multiple url in single webview?. first url is my site url, the second one is my community facebook page, the first one is opened in a webview but not the other one.
this is my codes:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("mysite.com")){
return false;
} else if (Uri.parse(url).getHost().equals("facebook.com")){
return false;
}
else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
And that was my first attempt, the second is:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if ((Uri.parse(url).getHost().equals("mysite.com"))|| (Uri.parse(url).getHost().equals("facebook.com"))){
return false;
} else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
I tried to replace facebook url with another site url but still no luck.
I am new to android so any explanations would be appreciated, thank you in advance..
err, maybe the problem is inside here? since loadUrl only load mysite url and not the other url?:
mwebView.loadUrl("mysite full url");
//handle link inside app
mwebView.setWebViewClient(new MyWebviewClient());

How to open Dialer Activity from a webviewclient?

I am using webviewclient to open the html page. The html page is having a anchor tag.
when i click on the anchor tag my phone dialer activity should be launched.
when i click on this anchor tag in external browser (android default browser ), it is launching the phone dialer, but as i am using the webviewclient (browser with in my application). i am unable to launch the phone dialer.
is there any way to achieve this using webviewclient ?
You should override this method
public boolean shouldOverrideUrlLoading(WebView wv, String url)
{
if(isNumber)
{
//Get the number from the URL
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:12345"));
startActivity(intent);
return true;
}
return false;
}
in the WebViewClient, and return ture that means you want to handle this by yourself instead of the webView.
The document is here.
I think is the best way to do this. So Please try this, I know i am too late to reply this:
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if( URLUtil.isNetworkUrl(url) ) {
view.loadUrl(url);
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity( intent );
return true; /*
return false;*/
}

Support for other protocols in Android webview

I've created a web view app, the page that is displayed features market:// links but upon clicking them I get the 404 screen along with the error that the protocol is not supported. I've tried looking through documentation but was unable to find anything relating to this. Any help is much appreciated.
For me the JavaScript thing wasn't a solution as the HTML is not under my control. So if you need to control this from the application side, then there is a relative simple solution: Derive from WebViewClientand inject the implementation using WebView.setWebViewClient(). All you need to override in your WebViewClientimplementation is the shouldOverrideUrlLoading method as shown here:
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url != null && url.startsWith("market://")) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else {
return false;
}
}
For me this works fine.
HOPE THIS HELPS YOU
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
if (url.startsWith("market://")||url.startsWith("vnd:youtube")||url.startsWith("tel:")||url.startsWith("mailto:"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
else{
view.loadUrl(url);
return true;
}
}
For the links to work you have to have the market app installed on your device/emulator.
Also your app need to request a permission to access network.
UPD:
as a workaround you can call java code from within the webview, for example if you generate links like this:
..
Define a javascript function named go():
<script type="text/javascript">
function go(link) {
if (handler) {
handler.go(link);
} else {
document.location = link;
}
}
</script>
You then can pass in a handler object into the WebView:
webview.addJavascriptInterface(new Handler() {
#Override
public void go(String marketUrl) {
//start market intent here
}
}, "handler");
Handler interface can be defined as follows:
public interface Handler{
public void go(String url);
}
Work for me:
webView = (WebView) findViewById(R.id.webView);
webView.setWebChromeClient(new WebChromeClient());
webView.getSettings().setPluginState(WebSettings.PluginState.ON);
webView.getSettings().setPluginState(WebSettings.PluginState.ON_DEMAND);
webView.setWebViewClient(new MyWebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://myweb.com");
private class MyWebViewClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url != null && url.startsWith("whatsapp://")) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else {
return false;
}
}
}
It is important to understand how the webview and its clients (webviewclient and webchromeclient) works. Please go through the http://therockncoder.blogspot.in/2014/04/understanding-androids-webchromeclient.html
In the webviewclient's shouldOverrideUrlLoading() method, you can decide if you want to open the link in new browser or within the webview. If you don't override this method, it will by default open the link in a new browser outside of the your android application.
If you want to open within webview, override the method as below
public boolean shouldOverrideUrlLoading(WebView view, String url) { <br>
Log.v("activity", "INSIDE WEBVIEW CLIENT ON shouldOverrideUrlLoading");
view.loadUrl(url);
return false; //need to understand return value based on usage
}
Schemes like whatsapp://send?text=Hello%20World! or market://details?id=xx.xx.xx will open the corresponding apps automatically if they are opened outside the webview and if that app is installed on the handset.
If you want to open certain links within webview and specific schemes outside webview, you need to override WebChromeClients onCreateWindow() method as explained in the link provided above. It should solve the purpose.
Instead of adding check for particular scheme, Modifying #sven solution, this will work for all schemes
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String host= Uri.parse(url).getHost();
if (host == null) {
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
}
view.loadUrl(url);
return false;
}
Simplest solution
Intent newApp = new Intent(Intent.ACTION_VIEW, Uri.parse(URL));
startActivity(newApp);
