Use this :-

public boolean isNetworkAvailable()
    {
        ConnectivityManager cmanager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
        NetworkInfo netInformation= cmanager .getActiveNetworkInfo(); 
        if (netInformation!= null && netInformation.isAvailable() && netInformation.isConnected()) 
        { 
            return true; 
        }
        return false; 
    }

BroadcastReceiver networkStateReceiver = new BroadcastReceiver() {

@Override
public void onReceive(Context context, Intent intent) {
    Log.w("Network Listener", "Network Type Changed");
}
};

IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);        
registerReceiver(networkStateReceiver, filter);

This is a example code.

u can also add info.isConnectedOrConnecting() option like this..

public static boolean checkConn(Context ctx)
{
    ConnectivityManager conMgr =  (ConnectivityManager)ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = conMgr.getActiveNetworkInfo();
    if (info == null || !info.isConnected() || !info.isAvailable()||!info.isConnectedOrConnecting()){
        Toast.makeText(ctx, "Internet is not available", Toast.LENGTH_SHORT).show();
        return false;
    }
     return true;
}

this is code I found here on Stackoverflow (don't remember who wrote it)

public static boolean isConnected(Context context) {
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = cm.getActiveNetworkInfo();
    if (info == null) {
        return false;
    }
    return info.isConnected();
}

requires internet and network_state permissions
