I have made an application in which i have used web view. but when there is no internet connection the application shows the url not found message or web page not found error message. what i want is that if there is no internet connection in the device then a toast message("Please check your internet connection") is displayed instead of loading URL. Please help in resolving this problem.
My code is below:-

Java

package com.iapits.jpsc;

import android.app.ActionBar;
import android.app.Activity;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import com.example.servesh.jpsc.R;

/**

 */
public class WebViewMethod extends Activity {

    private WebView view;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);
        view = (WebView) findViewById(R.id.webView1);
        view.setWebViewClient(new MyWebViewClient());
        String url = "http://android-mocktest-portal.indianstudyspot.in/issjpscquiz";

        view.getSettings().setJavaScriptEnabled(true);
       view.loadUrl(url);
        ActionBar actionBar = getActionBar();
        //ActionBar actionBar = getSupportActionBar();
        actionBar.setLogo(R.drawable.logo);
        actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));
        actionBar.setDisplayUseLogoEnabled(true);
        actionBar.setDisplayShowHomeEnabled(true);

    }

    private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }
}

-------------------

MainActivity.java

case R.id.bt12:

Java

@Override
   public void onClick(View v){
       switch(v.getId()) {

// Intent browserIntent = new Intent("android.intent.action.VIEW", Uri.parse("http://android-mocktest-portal.indianstudyspot.in/"));
startActivity(new Intent(this, WebViewMethod.class));
break;
}

To check if your device is internet connected or not use:

Java

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager 
          = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting();
}

Use a permission in your Manifest.xml:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

And then use the method like:

Java

if (!isNetworkAvailable) {
    // write your toast message("Please check your internet connection")
} else {
    // code
}
