Android check network connectivity on some tablets crash

Question

I know this topic has already been asked here, but I don't understand why my code is not working as expectd. I need to check data connectivity at launch of my app, but it crashes on some tablets (as Nexus 7), but not on all.

My code :

public static boolean getNetworkState(Context pContext)
{
    ConnectivityManager connect =  (ConnectivityManager)pContext.getSystemService(Context.CONNECTIVITY_SERVICE);

    if(connect != null)
    {
        if (connect.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnectedOrConnecting())
        {
            return true;
        }
        else 
        {
            return false;
        }
    }
    else
        return false;
}

public static boolean getWifiState(Context context)
{
    ConnectivityManager connect =  (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if ( connect.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting())
    {
        return true;
    }
    else 
    {
        return false;
    }
}

Connectivity check :

if(Commons.getNetworkState(this) || Commons.getWifiState(this))
        {
            loadData();
        }
        else
        {
            Commons.getConnectivityErrorMessage(this);
        }

Normally, if network connectivity is not supported on tablet, the "connectivity" object in "getNetworkState" should be null but it seems it's not the case because it crashed on line

 if (connect.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnectedOrConnecting())

What's wrong here? Permissions are already written

EDIT : Unfortunately, I don't have a tablet to test the problem. I just have user report on developer console. The following report has been reported by an user with a Nexus 7 :

EDIT 2 : all the permissions which I use :

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

This code works now :

public static boolean getNetworkState(Context pContext)
    {
        ConnectivityManager connect = null;
        connect =  (ConnectivityManager)pContext.getSystemService(pContext.CONNECTIVITY_SERVICE);

        if(connect != null)
        {
            NetworkInfo result = connect.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            if (result != null && result.isConnectedOrConnecting())
            {
                return true;
            }
            else 
            {
                return false;
            }
        }
        else
            return false;
    }
