Re: check network status

Absolutelly! Thanks for the valuable comments ...


This is my way of getting the preffered connection types. I think it matches with your (b) option ... I wasn't aware of the limitations that (a) gives.


private int[] getPreferredTransportTypes() {
		int[] availableTransports = TransportInfo.getAvailableTransportTypes();
		Vector temp = new Vector();
		if (isTransportTypeSupported(TransportInfo.TRANSPORT_MDS, availableTransports)) {
			temp.addElement(new Integer(TransportInfo.TRANSPORT_MDS));
		if (isTransportTypeSupported(TransportInfo.TRANSPORT_TCP_WIFI, availableTransports)) {
			temp.addElement(new Integer(TransportInfo.TRANSPORT_TCP_WIFI));
		if (isTransportTypeSupported(TransportInfo.TRANSPORT_BIS_B, availableTransports)) {
			temp.addElement(new Integer(TransportInfo.TRANSPORT_BIS_B));
		if (isTransportTypeSupported(TransportInfo.TRANSPORT_WAP2, availableTransports)) {
			temp.addElement(new Integer(TransportInfo.TRANSPORT_WAP2));
		if (isTransportTypeSupported(TransportInfo.TRANSPORT_TCP_CELLULAR, availableTransports)) {
			temp.addElement(new Integer(TransportInfo.TRANSPORT_TCP_CELLULAR));
		int size = temp.size();
		int[] result = new int[size];
		for (int i = 0; i < size; i++) {
			result[i] = ((Integer) temp.elementAt(i)).intValue();
		return result;

	public boolean isTransportTypeSupported(int type, int[] availableTransports) {
		int size = availableTransports.length;
		for (int i = 0; i < size; i++) {
			if (availableTransports[i] == type) {
				return true;
		return false;


The strangest thing is that I noticed that when using BIS, then 


 returns false, even if that connection is available - I could browse the internet using native browser.


So far I didn't experience any issues with above code ...

Re: check network status

Remember that to get BIS-B you need to have a parameter, that may be why it is not available.
