title: Android - How to check internet Access, not just connectivity to wifi?
body: <p>I tried the below code to check whether my mobile is connected to a wireless network and it works well when I want to know if my mobile is connected to the network, but it fails to give information about the internet access ... something like "Pinging" any website.
  Actually I followed many links but still no answer, so I'll be so thankful if anybody can help.</p>
  
  <p>Thanks in Advance.</p>
  
  <pre><code>@Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      Toast t = new Toast(getApplicationContext());
  
      if (isInternetOn()) {
           // INTERNET IS AVAILABLE, DO STUFF..
           Toast.makeText(ConnectivityTestActivity.this,"Network is Available", Toast.LENGTH_LONG).show();
  
           }
      else {
           // NO INTERNET AVAILABLE, DO STUFF..
          Toast.makeText(ConnectivityTestActivity.this,"No Network Available", Toast.LENGTH_LONG).show();
  
          }
  }
  
  public final boolean isInternetOn() {
  
  
      ConnectivityManager connec =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
      // ARE WE CONNECTED TO THE NET
      if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||
      connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTING ||
      connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTING ||
      connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED ) {
      // MESSAGE TO SCREEN FOR TESTING (IF REQ)
      //Toast.makeText(this, connectionType + ” connected”, Toast.LENGTH_SHORT).show();
      return true;
      } else if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED ||  connec.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED  ) {
  
      return false;
      }
      return false;
      }}
