If & else both get executed and executes else statement even if "if" condition is true in android (java)

I am trying to check network connectivity in my android application. For this, I am creating an object of ConnectivityManager to get the Connectivity_Service after that I am storing the ActiveNetwork Information in object of NetworkInfo class. Then, I am checking if the networkInfo object is null or not. I am getting a not null object so, I am setting a networkConnected flag = true and returning but both the statements if(networkConnected) as well as else get executed. And I get result false (which is in the else block). This is my code :-

public static boolean isNetworkConnected(Context ctx)
{
    ConnectivityManager connMgr = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = connMgr.getActiveNetworkInfo();
    Boolean networkConnected = false;


    if (netInfo != null)
    {
        if(netInfo.isConnectedOrConnecting())
        {
            networkConnected = true;    
        }

    }

    // The following if-else flow is surprising. Both of them are executed, even if
    // the networkConnected flag is true or false.
    // In both the cases false is returned.

    // WHEN NETWORK IS CONNECTED, CONTROL ENTERS "if" BLOCK AND ALSO ENTERS "else" BLOCK, FINALLY RETURNING FALSE.
    if(networkConnected)
    {
        return true;            
    }
    else
    {
        return false;   
    }

}

I am using eclipse JUNO on windows 7. Also I did search on google and SO but I didn't find any relevant help in this context. (They have examples where in if-else condition is wrong or some malformed parenthesis, none of them are close to this particular querry).

Kindly help, Thanks in advance.
