How can I add a share button on my android app

I want to add a share button on my app.

If users use the app there would be an option that they can share my app, but unfortunately it's not happening.

Here is my code:

MainActivity.java

package com.vvhvb.hesselfeenstra.vvheerenveenseboys;

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.app.AppCompatActivity;
import android.widget.ShareActionProvider;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        String url ="http://dehvb.nl/";
        WebView view=(WebView) this.findViewById(R.id.webView);
        view.getSettings().setJavaScriptEnabled(true);
        view.getSettings().setBuiltInZoomControls(true);
        view.getSettings().setDisplayZoomControls(false);
        view.loadUrl(url);

    }

    private ShareActionProvider mShareActionProvider;
    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_main, menu);
        MenuItem item = menu.findItem(R.id.menu_item_share);
        mShareActionProvider = (ShareActionProvider)MenuItemCompat.getActionProvider(item);
        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        String shareBody = "here goes your share content body";
        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Share Subject");
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);

        //then set the sharingIntent
        mShareActionProvider.setShareIntent(sharingIntent);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.menu_item_share) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

menu_main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.vvhvb.hesselfeenstra.vvheerenveenseboys.MainActivity">

    <item
        android:id="@+id/menu_item_share"
        app:showAsAction="ifRoom"
        android:title="Share"
        android:icon="@drawable/share"
        android:actionProviderClass="android.support.v7.widget.ShareActionProvider" />

</menu>

Firstly, modify your menu.xml file to include the share-action menu item:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.vvhvb.hesselfeenstra.vvheerenveenseboys.MainActivity">
    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_share"
        android:icon="@drawable/share"
        app:showAsAction="ifRoom" />
       <-- here is the share action menu item -->
       <item
            android:id="@+id/menu_item_share"
            app:showAsAction="ifRoom"
            android:title="Share"
            app:actionProviderClass=
            "android.support.v7.widget.ShareActionProvider" />
</menu>

Then change your onCreateOptionsMenu by adding the ShareActionProvider code based on the share-action menu item:

 //add the following imports (you may already have them)
    import android.support.v4.view.MenuItemCompat;
    import android.support.v7.app.AppCompatActivity;
    import android.support.v7.widget.ShareActionProvider;
    ...
    private ShareActionProvider mShareActionProvider;
    ...
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

      getMenuInflater().inflate(R.menu.menu_main, menu);
      MenuItem item = menu.findItem(R.id.menu_item_share);
      mShareActionProvider = (ShareActionProvider)MenuItemCompat.getActionProvider(item);
      //create the sharing intent
      Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
      sharingIntent.setType("text/plain");
      String shareBody = "here goes your share content body";
      sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Share Subject");
     sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);

     //then set the sharingIntent
     mShareActionProvider.setShareIntent(sharingIntent);
            return true;
  }

I hope this helps you. Please give it a try and let me know. You can also consult these closely related links:
