blackberry app not running on gprs connection in device - blackberry

Hi am trying to run my app on blackberry device using Edge gprs connection but its not rendering the pages.i have tried lot to get the connection,also i tried the various links to solve, one of the simple code i have attached here, kindly guide me to solve this
public static String getConnectionString() {
String value="" ;
if(WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
{
value=";interface=wifi";
}else{
value=";deviceside=true";
}
return value;
}

Append the connection string to your url. Then try
public static String getConnectionString() {
// This code is based on the connection code developed by Mike Nelson of
// AccelGolf.
// http://blog.accelgolf.com/2009/05/22/blackberry-cross-carrier-and-cross-network-http-connection
String connectionString = null;
// Simulator behavior is controlled by the USE_MDS_IN_SIMULATOR
// variable.
if (DeviceInfo.isSimulator()) {
connectionString = ";deviceSide=true";
}
// Wifi is the preferred transmission method
else if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
// System.out.println("Device is connected via Wifi.");
connectionString = ";interface=wifi";
}
// Is the carrier network the only way to connect?
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// System.out.println("Carrier coverage.---->>" + CoverageInfo.getCoverageStatus());
String carrierUid = getCarrierBIBSUid();
// DebugScreen.Log(" carrierUid is: " + carrierUid);
if (carrierUid == null) {
// Has carrier coverage, but not BIBS. So use the carrier's TCP
// network
// System.out.println("No Uid");
String wapString = getAvailableConnectionsString();
// DebugScreen.Log("from wap2 connection--->" + wapString);
if(wapString == null){
connectionString = ";deviceside=true";
}else{
connectionString = wapString;
}
} else {
// otherwise, use the Uid to construct a valid carrier BIBS
// request
connectionString = ";deviceside=true;connectionUID=" + carrierUid + ";ConnectionType=mds-public";
}
}
// Check for an MDS connection instead (BlackBerry Enterprise Server)
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
// System.out.println("MDS coverage found");
connectionString = ";deviceside=false";
}
// If there is no connection available abort to avoid bugging the user
// unnecssarily.
else if (CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE) {
// System.out.println("There is no available connection.");
}
// In theory, all bases are covered so this shouldn't be reachable.
else {
// System.out.println("no other options found, assuming device.");
connectionString = ";deviceside=true";
}
return connectionString;
}
Add this method and append connection String to url.
private static String getCarrierBIBSUid() {
ServiceRecord[] records = ServiceBook.getSB().getRecords();
int currentRecord;
for (currentRecord = 0; currentRecord < records.length; currentRecord++) {
// DebugScreen.Log("Util.getCarrierBIBSUid() for ippp--------->>" + records[currentRecord].getCid().toLowerCase());
if (records[currentRecord].getCid().toLowerCase().equals("ippp")) {
// DebugScreen.Log("Util.getCarrierBIBSUid() for bibs..........'''''" + records[currentRecord].getName().toLowerCase().indexOf("bibs") );
if (records[currentRecord].getName().toLowerCase().indexOf("bibs") >= 0) {
return records[currentRecord].getUid();
}
}
}
return null;
}
public static String getAvailableConnectionsString() {
String conns = null;
ServiceBook sb = ServiceBook.getSB();
ServiceRecord[] records = sb.getRecords();
String cid;
String uid;
for (int i = 0; i < records.length; i++) {
ServiceRecord myRecord = records[i];
// System.out.println("record name:"+myRecord.getName()+" cid:"+myRecord.getCid().toLowerCase()+" "+myRecord.getUid().toLowerCase());
if (myRecord.isValid() && !myRecord.isDisabled()) {
cid = myRecord.getCid().toLowerCase();
uid = myRecord.getUid().toLowerCase();
//Wap2.0
if (cid.indexOf("wptcp") != -1 && uid.indexOf("wifi") == -1 && uid.indexOf("mms") == -1 ) {
conns = ";deviceside=true" + ";ConnectionUID="+ myRecord.getUid();
if(myRecord.getUid().equalsIgnoreCase("GTCP BIBS")){
return conns;
}
}
}
}
return conns;
}
This code is work for me..

You need to append your connection type after your URL.

connectionString = ";deviceside=true";
} else {

connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mds-public";
}
}
// Check for an MDS connection instead (BlackBerry Enterprise Server)

else {
connectionString = ";deviceside=true";
}
return connectionString;

Once you writtent this code. use
con = (HttpConnection) Connector.open(url + getConnectionString());
It will determine available network type .

IOException Radio is off, and Out of memory, on BlackBerry

I am performing HttpConnection in my RIM Blackberry application. I am using wi-fi connection. While performing HttpConnection sometimes it is returning data, sometimes it is giving
java.io.IOException Radio is off
and
java.io.IOException Out of memory
errors. I really do not understand what is the issue exactly. I am posting here my code snippets:

InputStream input = fconImg.openInputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int k = 0;
while ((k = input.read()) != -1) {
baos.write(k);
}
byte[] byteArray = baos.toByteArray();

stringBuff.append(s.trim());

I don't know if it's the problem but you are not closing your ByteArrayOutputStream (call baos.close() ) before calling .toByteArray()

HttpConnection connect with Mobile Network or 3G

When I run this application on a device using the WiFi
it's working fine. But when I am using a mobile network or 3g it's giving an error.
It's not working on the mobile network.
I am using this code:
connection = (HttpConnection) Connector.open(APIURL+ updateConnectionSuffix());
And my ConnectionTools class code:
public String updateConnectionSuffix() {
String connSuffix;
if (DeviceInfo.isSimulator()) {
connSuffix = ";deviceside=true";
} else if ((WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
&& RadioInfo.areWAFsSupported(RadioInfo.WAF_WLAN)) {
connSuffix = ";interface=wifi";
} else {
String uid = null;
ServiceBook sb = ServiceBook.getSB();
ServiceRecord[] records = sb.findRecordsByCid("WPTCP");
for (int i = 0; i < records.length; i++) {
if (records[i].isValid() && !records[i].isDisabled()) {
if (records[i].getUid() != null
&& records[i].getUid().length() != 0) {
if ((records[i].getCid().toLowerCase().indexOf("wptcp") != -1)
&& (records[i].getUid().toLowerCase().indexOf(
"wifi") == -1)
&& (records[i].getUid().toLowerCase().indexOf(
"mms") == -1)) {
uid = records[i].getUid();
break;
}
}
}
}
if (uid != null) {
// WAP2 Connection
connSuffix = ";ConnectionUID=" + uid;
} else {
connSuffix = ";deviceside=true";
}
}
return connSuffix;
}
Can you give me any solutions?
What should we do for the mobile network or 3g?
Try this code.
public static String getConnectionString() {
String connectionString = null;
// Simulator behaviour is controlled by the USE_MDS_IN_SIMULATOR
// variable.
if (DeviceInfo.isSimulator()) {
connectionString = ";deviceside=true";
}
// Wifi is the preferred transmission method
else if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
connectionString = ";interface=wifi";
}
// Is the carrier network the only way to connect?
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 {
// otherwise, use the Uid to construct a valid carrier BIBS
// request
connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mds-public";
}
}
// Check for an MDS connection instead (BlackBerry Enterprise Server)
else if ((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
connectionString = ";deviceside=false";
}
// If there is no connection available abort to avoid hassling the user
// unnecssarily.
else if (CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE) {
connectionString = "none";
}
// In theory, all bases are covered by now so this shouldn't be reachable.But hey, just in case ...
else {
connectionString = ";deviceside=true";
}
return connectionString;
}
/**
* Looks through the phone's service book for a carrier provided BIBS
* network
*
* #return The uid used to connect to that network.
*/
private synchronized static String getCarrierBIBSUid() {
ServiceRecord[] records = ServiceBook.getSB().getRecords();
int currentRecord;
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();
}
}
}
return null;
}
Replace this function by your updateConnectionSuffix().
Let me explain : - This is for connection using mobile network 2g or 3g any network" just copy & paste & enjoy
String url = "vm.b24esolution.com:9090";
final HttpConnection connection = (HttpConnection) Connector.open("socket://"+url+updateConnectionSuffix()+";apn=rim.net.gprs;tunnelauthusername =;tunnelauthpassword=",Connector.READ_WRITE);

Enabling Multiple Connection Type

I have a HTTP Connection on my application, for the current time being it is only applicable if the users are connected to WIFI connection. How would I do this if I'd like to enable it for any connections that the particular device has? Say that the device has a BIS service, or even a normal WAP service.
This is my code.
try
{
connection = (HttpConnection) Connector.open(url+ ";interface=wifi");
is = connection.openInputStream();
try
{
SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
parser.parse(is, rssHandler);
}
catch (ParserConfigurationException e)
{
e.printStackTrace();
}
catch (SAXException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}
catch (IOException e)
{
e.printStackTrace();
Dialog.inform("Bad URL");
}
Use the following code to get the connection string
/**

Check wifi condition in Blackberry application

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?
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();
