Check wifi condition in Blackberry application - blackberry

Question

I have developed an application for blackberry devices. The application is working fine if it uses internet via data service provider.
I have BB 9550 and I want to use my application using wifi. I tried a lot but I cant get proper answer to check wifi condition.
How we can differentiate to run our application for wifi or data service provider?

Answer 1

For checking wifi is connected or not the following method will help you.
public static boolean isWifiConnected()
{
try
{
if (RadioInfo.getSignalLevel(RadioInfo.WAF_WLAN) != RadioInfo.LEVEL_NO_COVERAGE)
{
return true;
}
}
catch(Exception e)
{
System.out.println("Exception during get WiFi status");
}
return false;
}
if wifi is not connected the following methods will help to add data service.
public static String getConnParam(){
String connectionParameters = "";
if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
// Connected to a WiFi access point
connectionParameters = ";interface=wifi";
} else {
int coverageStatus = CoverageInfo.getCoverageStatus();
ServiceRecord record = getWAP2ServiceRecord();
if (record != null
&& (coverageStatus & CoverageInfo.COVERAGE_DIRECT) ==
CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage and a WAP 2.0 service book record
connectionParameters = ";deviceside=true;ConnectionUID="
+ record.getUid();
} else if ((coverageStatus & CoverageInfo.COVERAGE_MDS) ==
CoverageInfo.COVERAGE_MDS) {
// Have an MDS service book and network coverage
connectionParameters = ";deviceside=false";
} else if ((coverageStatus & CoverageInfo.COVERAGE_DIRECT) ==
CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage but no WAP 2.0 service book record
connectionParameters = ";deviceside=true";
}
}
return connectionParameters;
}
private static ServiceRecord getWAP2ServiceRecord() {
ServiceBook sb = ServiceBook.getSB();
ServiceRecord[] records = sb.getRecords();
for(int i = 0; i < records.length; i++) {
String cid = records[i].getCid().toLowerCase();
String uid = records[i].getUid().toLowerCase();
if (cid.indexOf("wptcp") != -1 &&
uid.indexOf("wifi") == -1 &&
uid.indexOf("mms") == -1) {
return records[i];
}
}
return null;
}
Example to use above methods.
String connParams=(isWifiConnected())?";interface=wifi":getConnParam();
Hope This will help you

try this:
private static String getParameters() {
if (GetWiFiCoverageStatus()) {
return ";deviceside=true;interface=wifi";
}
else {
return yourParametersForEdge
}
}
private static boolean GetWiFiCoverageStatus() {
if((WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)) {
return true;
}
else
return false;
}
And when you need to connect, you'll have to add the parameters to the URL:
yourUrl = yourUrl + getParameters();
