Question

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..
