Description

In src/android/NetworkManager.java, all the static final String constants are written in all lowercase. When checking the type in GetType(), the code already makes this adjustment:

private String getType(NetworkInfo info) {
if (info != null) {
String type = info.getTypeName().toLowerCase(Locale.US);

However, if type == MOBILE or CELLULAR, the subType is not converted to all lowercase:

else if (type.equals(MOBILE) || type.equals(CELLULAR)) {
type = info.getSubtypeName();
if (type.equals(GSM) ||
type.equals(GPRS) ||

For me, running on the Android emulator and pushing to a device, this was causing the app to always fail every subType comparison, and always return Connection.UNKNOWN, resulting in an app that was always 'offline'.

After debugging the plugin, it looked like subTypes were coming in as 'GSM' and 'UMTS' in all-caps, and being compared to 'gsm' and 'umts', the lower-case pre-defined strings. I added a .toLowerCase() to the subType get, and everything seems to be working fine for me:

else if (type.equals(MOBILE) || type.equals(CELLULAR)) {
type = info.getSubtypeName().toLowerCase();
if (type.equals(GSM) ||

I'm not sure why this was an issue for me, but hasn't been in the past for other users. I can submit whatever environment info you might want if you let me know. Thanks!
