Hi,
I want to check whether mobile data is on/off, and for this I use the below
code
ConnectivityManager cm = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);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);
However, this code does not work on some devices, and throws an exception that
no such method exists. I have found it is not working in Android 4.1.x. Why is
it throwing this execption, and how can I fix it?
