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;

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:

// the dialog box and do nothing
dialog.cancel();
}
});
// create alert dialog

// show it
alertDialog.show();
}
}
I will try to read the version from the realtime database here:
case R.id.KoriAbout:
Toast.makeText(MainActivity.this, "Version: 0.3b", Toast.LENGTH_LONG).show();
But I don't know how to setup this with the Realtime Database from Firebase.
A picture from my database :

its real time by default...I believe. if you change it in firebase, it'll change it on your app. but, for what you have, you have it hard coded into your toast.
You need to do something like this:
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myRef = database.getReference("version");
// Read from the database
myRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
// This method is called once with the initial value and again
// whenever data at this location is updated.
String value = dataSnapshot.getValue(String.class);
Log.d(TAG, "Value is: " + value);
}
#Override
public void onCancelled(DatabaseError error) {
// Failed to read value
Log.w(TAG, "Failed to read value.", error.toException());
}
});

You may need to create an xml file inside res>menu directory of your project for a share menu,
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/share"
android:icon="#drawable/ic_action_share" // share button icon.
android:showAsAction="always"
android:title="#string/action_share">
</item>
</menu>
In your java file,
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.desc_xml, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
if (itemId == R.id.share) {
shareNews();
}
return super.onOptionsItemSelected(item);
}
and here is the share news method,
private void shareNews() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Put Data Here");
startActivity(Intent.createChooser(shareIntent,getString("How do you want to share")));
}

This question has already been answer but anyway, this is a working solution :
in your fragment/activity:
private ShareActionProvider mShareActionProvider;
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
getActivity().getMenuInflater().inflate(R.menu.deal_detail, menu);
// Locate MenuItem with ShareActionProviderr
MenuItem item = menu.findItem(R.id.action_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
mShareActionProvider.setShareIntent(getShareIntent());
}
// Create the share intent
private Intent getShareIntent() {
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "yoursubject");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "yourtext);
return sharingIntent;
}
