Android WebView URL problems

I have android app hosting a web site in WebView. It works fine, but has one issue. Whenever users search in Google and click on page of this site, the application is opening not at that page but on home page of the web site.
For example: they click on www.example.com/blog - WebView app is open but it shows homepage, not blog.
Links (navigation) works fine inside of application when it starts.

try these code
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.loadUrl(request.getUrl().toString());
return false;
}
});
when you click on any link on webview then view.loadurl() method again load new url.

webview hyperlink opening in default web browser

I have a android app which contains jsp page.
On this jsp page one hyperlink is created and linked another jsp page which contains download pdf code.
When I click on hyperlink it will open in android default browser and download starts.
I want to download pdf inside web view without opening web browser.

For that you can use like this:
Every time you click a link WebViewClient's shouldOverrideUrlLoading method will be called. Check that url points to pdf file and do what you want. For example, you can view pdf.
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading (WebView view, String url) {
if (url.endsWith(".pdf")) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
// if want to download pdf manually create AsyncTask here
// and download file
return true;
}
return false;
}
});

can we use browser other than chrome to load web activity in android

In my app I am trying to open web application which needs flash player but as I am new to android I only know opening web view with chrome client. is there any method to open webview with any other browser instead of chrome.
I am planing to open that web activity in puffin browser as it supports flash player

Write this to open URL in your own webview :
web.setWebViewClient(new myWebClient());
To enable Javascript :
web.getSettings().setJavaScriptEnabled(true);
When the user clicks a link from a web page in your WebView, the default behavior is for Android to launch an application that handles URLs. Usually, the default web browser opens and loads the destination URL. However, you can override this behavior for your WebView, so links open within your WebView.
EDIT
Add this to your code and see if its work:
Make sure shouldOverrideUrlLoading(...) should return false to prevent the default browser from being opened.
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
}

Prevent link to be opened in external browser with WebChromeClient

I've developed a small group of .html pages that are stored in a server.
My android app, using a webview with: setWebChromeClient loads these pages.
minSdkVersion 19
targetSdkVersion 24
The problem:
Everytime I need to load a new page, using a link in my .html page, the new page is opened in an external browser.
Url Overriding
I know about the shouldOverrideUrlLoading() method, when we're using the setWebViewClient().
But unfortunately I can't use the normal webview. I need to use the WebChromeClient() because of some feature that only work with this one. (Like the input file)
My doubt is...
How can I override my URL to force them to load inside of the webChromeClient?
I tried this but with no luck:
webView.setWebChromeClient(new WebChromeClient() {
// (...)
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});

You can use following code to achieve this.
WebView web = (WebView)findViewById(R.id.web);
WebSettings webSettings = web.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportMultipleWindows(true); // This forces ChromeClient enabled.
web.setWebChromeClient(new WebChromeClient(){
#Override
public void onReceivedTitle(WebView view, String title) {
getWindow().setTitle(title); //Set Activity tile to page title.
}
});
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});

I was using an embedded mobile web application in an Android App making use of the WebChromeClient class and did not want to fiddle around with recompiling the APK.
While looking for the easiest header(); solution (since the mobile web application is in php) I found out that using:
header("Location: url.php", TRUE, 307);
was a quick fix solution without recompiling the Android app.
This allowed the user to re-direct within the app without calling the web browser externally from my app.
Here is the link to the answer by Arindam Nayak where I got the idea from.

How do I open another app in my WebView app?

I have an Android app with that displays a mobile website (WebView), in the mobile website there are links redirecting to a PDF, Excel and video files.
When try to open it in my regular browser my phone asks to open it with another app or it start a download, so I can open it afterwards.
But in my WebView app it either doesn't work, no response or it displays a "Page unavailable" error.
Is it even possible?

To handle links in WebView, you can use the shouldOverrideUrlLoading method of WebViewClient class. Consider the following example;
WebView webView = (WebView) findViewById(R.id.infoView);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// Assuming you are giving link to some PDF file.
if (url.contains(".pdf")) {
// Now do what you want to with the url here
}
return true;
}
}
This way, you can intercept any link tapped in WebView and then do whatever you want.
