I am expecting to work on all android similar to working on my device.

share current url in webview from toolbar menu

I am stuck at the last phase of my project. I am developing a android webview app in which user can share the current loaded page in there social apps. My share button is in the top at the toolbar. Currently I am able to share the loaded url through the share button but when I jump to a new page and press share button, still initial loaded url is shared. Here I need to share the current url from the toolbar menu.
Please help
Following is my code
package com.newsflashjharkhand.newflash;
import android.content.DialogInterface;
import android.content.Intent;
import android.graphics.Bitmap;

private String mTitle = "";
#Override

superImageView = findViewById(R.id.newsimage);
superWebView = findViewById(R.id.newswebview);
superProgressBar.setMax(100);
superWebView.loadUrl("https://www.google.com/");
superWebView.getSettings().setJavaScriptEnabled(true);
superWebView.setWebViewClient(new WebViewClient(){

}
#Override

}
});
superWebView.setWebChromeClient(new WebChromeClient(){

superProgressBar.setProgress(newProgress);
}
});
}
#Override

You should set WebViewClient with your webview like below:
WebView webview = new WebView(context);
webview.setWebViewClient(new WebViewClient()
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
Log.d("WebView", "your current url when webpage loading.." + url);
}
#Override
public void onPageFinished(WebView view, String url) {
Log.d("WebView", "your current url when webpage loading.. finish" + url);
super.onPageFinished(view, url);
}
#Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("when you click on any interlink on webview that time you got url :-" + url);
return super.shouldOverrideUrlLoading(view, url);
}
});
You can get current loaded url from shouldOverrideUrlLoading() .

Capture the data provided by Intent

On this page: https://developer.android.com/training/app-links/deep-linking, in the
'Read data from incoming intents'
section, Google mentions:
Once the system starts your activity through an intent filter, you can
use data provided by the Intent to determine what you need to render.
Call the getData() and getAction() methods to retrieve the data and
action associated with the incoming Intent.
And that's exactly what I'm trying to do, but, I'm unable to get help.
In this activity of mine:
package com.application;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
#SuppressWarnings("unused")
public class SplashActivity3 extends Activity
{
Handler Handler;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash3);
Handler = new Handler();
Handler.postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(SplashActivity3.this, MainActivity.class);
startActivity(intent);
finish();
}
},
1500);
Intent appLinkIntent = getIntent();
String appLinkAction = appLinkIntent.getAction();
Uri appLinkData = appLinkIntent.getData();
}
}
I want to know (later tranfer it to another activity), the URL that was clicked on to open my app.
Basically, my app is using App Links (referred to as Deep Linking by some). So, in a case where a user 'A', sends user 'B' a link of a page on my website and B has my app installed, he/she will be able to open the link in my app instead of the browser.
As of now, B can open the link in my app, but, my app will always load the 'home page' (it's because I have coded my app to open the home page by default). I want to load the page that brought B in my app.
For a real life example, just like Facebook's app does. Suppose I share a link of a Facebook page or a profile to my friend. It's a standard HTTP link that's displayed in my web browser. Probably, I shared it with him on WhatsApp. He touches the link to open it. He has the official Facebook app installed on his phone. So, Android asks him if he wants to open the link in the Facebook app or in the browser. Now, when he chooses the browser, it's no problem at all. But, when he chooses the Facebook app, the app loads the profile or the page that exists on the link and not the home page of Facebook. That's what I want to achieve.
Please note, I'm talking about standard HTTP links here and not my app specific URIs.
UPDATE:
Here's something I tried now:
This is the same activity as above, I modified it like this:
package com.application;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
#SuppressWarnings("unused")
public class SplashActivity3 extends Activity
{
Handler Handler;
#Override
protected void onCreate(Bundle savedInstanceState)
{
final Intent appLinkIntent = getIntent();
final String appLinkAction = appLinkIntent.getAction();
Uri appLinkData = appLinkIntent.getData();
final Bundle bundle = new Bundle();
bundle.putString("web", appLinkAction);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash3);
Handler = new Handler();
Handler.postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(SplashActivity3.this, WebViewActivity.class);
intent.putExtras(bundle);
startActivity(intent);
finish();
}
},
1500);
}
}
And the activity in which I'm loading the URL:

Swipe to refresh webview fragment doesnt load url

I have a webview fragment in my MainActivity. I am trying to add Swipetoview inside it. But when I load the fragment it doesn't load the url.
My fragment:
// Inflate the layout for this fragment
View vDriver=inflater.inflate(R.layout.fragment_drivers, container, false);
mWebView = vDriver.findViewById(R.id.drivers_webview);
mWebView.loadUrl("https://ahmetbarpa-grand-prix.firebaseapp.com/drivers.html");
// Enable Javascript
//WebSettings webSettings = mWebView.getSettings();
//webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
swipeLayout = vDriver.findViewById(R.id.fragment_drivers);
swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
mWebView.reload();
new Handler().postDelayed(new Runnable() {
#Override public void run() {
swipeLayout.setRefreshing(false);
}
}, 5000);
}
});
return vDriver;
My fragment layout:
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/fragment_drivers"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Drivers">
<WebView
android:id="#+id/drivers_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.SwipeRefreshLayout>
I tried different things and this is the last code I tried. What am I doing wrong?
Thanks for your time in advance.

Instead of reload()
mWebView.loadUrl("https://ahmetbarpa-grand-prix.firebaseapp.com/drivers.html");
Try it..
If this is not the way you want, the second method is:
make a new class as:
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
then, Instead of this:
mWebView.setWebViewClient(new WebViewClient());
write this:
mWebView.setWebViewClient(new MyBrowser());
Hopefully your problem will be solved

Hide a menu item when a specific URL is loaded in WebView

I have an activity with a basic WebView. In that, I have a menu item which launches a Share intent and allows users to share the URL that they were browsing at that point of time. I also have an error HTML page which is loaded when the WebView gets any HTTP error. So, basically, I want the Share menu item to be hidden (or at least share some other URL that I can set) when that error document is loaded.
Here's my MainActiviity.java:

break;

Regarding hiding the share menu icon, you could always use onPrepareOptionsMenu() to hide your share menu if there is an error flag.
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
menu.findItem(R.id.share).setVisible(!isPageError);
return true;
}
which would require you to have a isPageError boolean set to true in your
#Override
public void onReceivedError(WebView webview, int i, String s, String s1{
isPageError = true;
}

I solved it using moving my error page to another activity. This is my new MainActiviy.java:
