I have problem in my Blackberry application.Actually I have developed a Blackberry chat application using third party server for instant messaging and also some code for webservice calls.
The app is working fine on WIFI network but when I try to run the app on Carrier Network it shows
Server Authentication Failed
Here is the code for ConnectionString:
public static String getConnectionString() {
String connectionString = "";
if (DeviceInfo.isSimulator()) {
if (USE_MDS_IN_SIMULATOR) {
connectionString = ";deviceside=false";
} else {
connectionString = ";deviceside=true";
}
}
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
String carrierUid = getCarrierBIBSUid();
if (carrierUid == null) {
// Has carrier coverage, but not BIBS. So use the carrier's TCP
// network
connectionString = ";deviceside=true";
} else {
connectionString = ";deviceside=false;connectionUID=" + carrierUid + ";ConnectionType=mds-public";
}
}
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
connectionString = ";deviceside=false";
}
else if (CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE) {
}
else {
connectionString = ";deviceside=true";
}
if ((RadioInfo.getActiveWAFs() & RadioInfo.WAF_WLAN) != 0
&& WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
connectionString += ";interface=wifi";
}
connectionString += ";ConnectionTimeout=30000";
return connectionString;
}
Here is the code for get BIS carrier:
public static String getCarrierBIBSUid() {
ServiceRecord[] records = ServiceBook.getSB().getRecords();
int currentRecord;
try{
for (currentRecord = 0; currentRecord < records.length; currentRecord++) {
if (records[currentRecord].getCid().toLowerCase().equals("ippp")) {
if (records[currentRecord].getName().toLowerCase().indexOf("bibs") >= 0) {
return records[currentRecord].getUid();
}
}
}
}catch (Exception e) {
}
return null;
}
You probably do not have the correct suffix for BIS. Have a look at how tricky the code is. There are many things to consider and it's easy to make mistakes. This is how things where done in pre-5.0 times.
Fortunately, now we have ConnectionFactory, that makes things much easier.

I have a Xamarin forms application. The application programmatically connects to a an access to point to communicate via sockets with a host machine connected to that same access point. The access point is not required to have internet access. When testing my code in iOS - I get a socket error stating that the 'Destination is unreachable'. However, if I go to settings and click on the wifi connection I want to use - I am taken to the login page for the access point. If I click cancel I get the option to 'Use without Internet'. If I select that option, then go back to my application, I am able to connect to the host. Is there a way to programmatically tell iOS to use the connecting even though it does not have internet? I looked at the Zone property but that is read only. Here is the code I am using. Any assistance would be appreciated.
public async Task<WifiConfiguredEventArgs> ConnectToWifi()
{
try
{
var tobj_WifiManager = new NEHotspotConfigurationManager();
var tobj_SSIDs = await tobj_WifiManager.GetConfiguredSsidsAsync();
if (tobj_SSIDs != null && tobj_SSIDs.Contains(App.gvm_AppSettings.WifiSSID))
{
// We are already connected -- just return
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eAlreadyConnected;
}
else
{
var tobj_WifiConfig = new NEHotspotConfiguration(App.gvm_AppSettings.WifiSSID, App.gvm_AppSettings.WifiPassword, false);
tobj_WifiManager.ApplyConfiguration(tobj_WifiConfig, async (error) =>
{
if (error != null)
{
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eErrorEstablishingConnection;
lobj_WifiConfiguredEventArgs.ErrorMessage = error.ToString();
}
else
{
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eConnectionEstablished;
}
});
}

Someone asked for the socket code so here it is. To be clear, the socket code connects and communicates fine in iOS when the access point has an internet connection. It also works fine in all the android calls.

I have a web api call that I recently added to my app. I returns a complete list of all countries, states and cities in the app (currently 486 rows) I perform this call when all of the reference data for my application loads (I have a base loading page and call the function in my startup class to load all the data there). The challenge is that the call to get all my countries.... hangs and eventually I get "The operation was canceled" error. If I modify my stored procedure that selects the data from the database on the server to only return say 20 rows, it runs fine. Any suggestions?

So after much time, I believe I figured out what the problem is. The problem started to manifest itself again with smaller amounts of data and I could not figure out why. The problem appeared. The issue appears to be the IP address I was using. (I was using the IP address of the actual laptop I was hosting both the App and WebAPIs on.) It appears you have to use one of the other network adaptors for the emulator to have this work reliably.
Here are the steps I used to resolved this:
I launched my Windows 10 mobile emulator.
Click on the >> (Tools) icon in the tool bar of the emulator.
Click on the Network tab of the Additional Tools window.
Look in the list for the network adaptor labeled Desktop Adaptor #1 and copy the IP address.
Edit the Applicationhost.config file in the folder of the WebAPI project.
Find the entry in the file for site name="XXXXX" where XXXXX is the name of the Visual Studio project you are hosting your WebAPIs in.
Within the section of the entry for your WebAPI project, add a binding for the IP address you copied from in step 4. It should look something like this:
<binding protocol="http" bindingInformation="*:56952:169.254.69.220" />
Where 56952 is the port my IIS Express is hosting the WebAPIs on and 169.254.69.220 is the IP address I copied from step 4. After adding this, I was able to connect to locally hosted WebAPIs in IIS Express.
Hope this helps.

So how can i confirm that there is no issue in my implementation or there is issue from server end.
There are couple of steps you can take to debug this problem:-
There is broadcast and sending notification, using notification hub, option available on azure portal(you can do from VS also from left side server explorer). When you did this there is a log that will show you whether a notifications sent successfully or not.
First just delete all your registrations with notification hub and for very new registration check is your device getting registered with correct tags/channel uri or not(this you cad do from server explorer too)
Make sure you are sending/registering the correct templates that are corresponding to WNS service.
make sure you are using WNS service this different from what is for
WP8 silverlight one.
You can see the errors just at the bottom of this page if any.
There is option for device registrations from where you can alter the registrations.

Unable to connect to internet in Blackberry device?
I'm trying to send an http request and get a response via blackberry. I used following code snippet.
String url="http://www.google.lk/";
HttpConnection con = null;

But the code never passes LINE X. There's no error. It just waits and eventually gets a timeout. What could be the problem?

I'm after some BlackBerry suggestions again. I'm developing a REST based app using the standard BB code that appends to the URI connection string (I'll post if you like but don't want to take up space here as I suspect that those of you that know about this know exactly what I mean).
The code works fine in the emulator in MDS mode and is good on the phone too with straight WiFi.
Now, the problem is when I come to use 3G on an actual phone. At that point it fails. Is this some kind of transcoding problem?
I'm using a raw HttpConnection.
An HTTP POST works (with body info) but the GET (which uses a cookie for auth purposes as a header requestproperty) fails.
The failure is only with header (GET) based info on non WiFi connections on the mobile device.
Any suggestions would be most appreciated.
public static String httpGet(Hashtable params, String uriIn) {
String result = null;
LoginDetails loginDetails = LoginDetails.getInstance();

Fixed - see above.
It turns out that there were spaces in the uri's.
Quite why this worked over WiFi & not 3G etc. is still puzzling.
