Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

Apps won't be able to alter the APN database after Honeycomb or perhaps ICS.  The User can disable data from settings.  Why does an application need to disable data?

Hi,

I have been googling for a while able the best or right way to disable/enable mobile network.

I tried the following code which is all over Stackoverflow and is working fine for gingerbread and higher:

private void setMobileDataEnabled(Context context, boolean enabled)
throws Exception {
final ConnectivityManager conman = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class<?> conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass
.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField
.get(conman);
final Class<?> iConnectivityManagerClass = Class
.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass
.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);

setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
}

Somehow I didn't find a way to do the same thing for Android 2.2 and below. Many mentioned to change the APN name to something invalid like what app APNDroid did but is that the only way?
