title: Check internet status from the main activity
body: <p>I'm new student on android development, so I don't have the enough experience for coding, so I need the help from you...
  I create a java class on android studio to check if there is an internet connection or not :</p>
  
  <pre><code>import android.app.Activity;
  import android.content.Context;
  import android.net.ConnectivityManager;
  import android.net.NetworkInfo;
  import android.util.Log;
  import java.io.IOException;
  import java.net.HttpURLConnection;
  import java.net.URL;
  
  
  public class InternetStatus {
  private static final String LOG_TAG ="InternetStatus";
  public static boolean hasActiveInternetConnection(Context context) {
      if (isNetworkAvailable((Activity) context)) {
          try {
              HttpURLConnection urlc = (HttpURLConnection) (new     URL("http://www.google.com").openConnection());
              urlc.setRequestProperty("User-Agent", "Test");
              urlc.setRequestProperty("Connection", "close");
              urlc.setConnectTimeout(1500);
              urlc.connect();
              return (urlc.getResponseCode() == 200);
          } catch (IOException e) {
              Log.e(LOG_TAG, "Error checking internet connection", e);
          }
      } else {
          Log.d(LOG_TAG, "No network available!");
      }
      return false;
  }
  public static boolean isNetworkAvailable(Activity mActivity) {
      Context context = mActivity.getApplicationContext();
      ConnectivityManager connectivity = (ConnectivityManager) context
              .getSystemService(Context.CONNECTIVITY_SERVICE);
      if (connectivity == null) {
          return false;
      } else {
          NetworkInfo[] info = connectivity.getAllNetworkInfo();
          if (info != null) {
              for (int i = 0; i &lt; info.length; i++) {
                  if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                      return true;
                  }
              }
          }
      }
      return false;
  }
  
  
  }

  <p>So, I have two questions :</p>
  
  <p>1- is this the right code or I'm missing something ?</p>
  
  <p>2- as you see this is a java class, if I create a button on my main activity to check if there is an internet connection or not !! how I can do that by importing this class or something like that ?!!</p>
