How to tell if ‘Mobile Network Data’ is enabled or disabled (even when connected by WiFi)?

by

The following code will tell you if “mobile data” is enabled or not, regardless of whether or not there is a mobile data connection active at the moment or whether or not wifi is enabled/active or not. This code only works on Android 2.3 (Gingerbread) and later. Actually this code also works on earlier versions of Android as well 😉

    boolean mobileDataEnabled = false; // Assume disabled
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    try {
        Class cmClass = Class.forName(cm.getClass().getName());
        Method method = cmClass.getDeclaredMethod("getMobileDataEnabled");
        method.setAccessible(true); // Make the method callable
        // get the setting for "mobile data"
        mobileDataEnabled = (Boolean)method.invoke(cm);
    } catch (Exception e) {
        // Some problem accessible private API
        // TODO do whatever error handling you want here
    }

Note: you will need to have permission android.permission.ACCESS_NETWORK_STATE to be able to use this code.
