I am getting RunTime Exception when I am Running this code..Please Go Through it and Help me if you have any idea. Thanks..
private void sendSMS(String phone, String message) throws IOException

MessageConnection conn =

tmsg.setAddress("sms://+919429441335");
tmsg.setPayloadText("HIIiii");
System.out.println("Text message is>>"+tmsg);
conn.send(tmsg);
}
instead of
System.out.println("Text message is>>"+tmsg);
use
System.out.println("Text message is>>"+tmsg.getPayloadText());
Also Connector.open is a blocking operation and should not be called from a main event thread.
You have Dialog.alert which will only work on a event thread. Do this
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
Dialog.alert("Hello..In Send SMS Function");
}
});
Try this code . this starts a new thread and calls sendsms method
new Thread(new Runnable() {
public void run() {
try {
sendSMS("123456789","message");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
private void sendSMS(String phone, String message) throws IOException
{
try {
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {

}
});
System.out.println("in send sms function");
MessageConnection conn =
(MessageConnection)Connector.open("sms://+919099956325");
TextMessage tmsg = (TextMessage) conn.newMessage(MessageConnection.TEXT_MESSAGE);

System.out.println("Text message is>>"+tmsg.getPayloadText());

I am trying to get a message from the MQTT Broker using the Android service, but it does not work.
The library used is the Paho MQTT library, and the source code is as follows.
final MqttConnectOptions hIoTConnectionOptions = new MqttConnectOptions();
hIoTConnectionOptions.setMqttVersion(MqttConnectOptions.MQTT_VERSION_3_1);
hIoTConnectionOptions.setAutomaticReconnect(true);
hIoTConnectionOptions.setCleanSession(false);`
try {
hIoTAndroid = new MqttClient(ip_addr, clientID, new MemoryPersistence());
IMqttToken conToken = hIoTAndroid.connectWithResult(hIoTConnectionOptions);
hIoTAndroid.setCallback(MqttMessagingService.this);
conToken.setActionCallback(new IMqttActionListener() {
#Override
public void onSuccess(IMqttToken asyncActionToken) {
Log.d(TAG, "onSuccess");
hIoTAndroid.setCallback(MqttMessagingService.this);
try {
IMqttToken subToken = hIoTAndroid.subscribeWithResponse(subtopic, 1);
subToken.setActionCallback(new IMqttActionListener() {
#Override
public void onSuccess(IMqttToken asyncActionToken) {
Log.i(TAG, "Successfully subscribe to: " + subtopic);
}
#Override
public void onFailure(IMqttToken asyncActionToken, Throwable exception) {
Log.d(TAG, "Couldn't subscribe to: " + subtopic);
}
});
} catch (MqttException | NullPointerException ex) {
ex.printStackTrace();
}
}
#Override
public void onFailure(IMqttToken asyncActionToken, Throwable exception) {
Log.d(TAG, "Failed Connection");
}
});
} catch (MqttException ex) {
Log.d(getClass().getCanonicalName(), "Connection attempt failed with reason code = " + ex.getReasonCode() + ":" + ex.getCause());
}
#Override
public void connectComplete(boolean reconnect, String serverURI) {
Log.d(TAG, "Connection is established....");
}
#Override
public void connectionLost(Throwable cause) {
Log.d(TAG, "The Connection was lost,,");
}
#Override
public void messageArrived(String topic, MqttMessage message) throws Exception {
Log.i(TAG, new String(message.getPayload()));
}
#Override
public void deliveryComplete(IMqttDeliveryToken token) {
Log.d(TAG, "Sent Message !");
}
The publish and deliveryComplete functions work fine, but the subscribe function and messagArrived do not work. Why?
I am working on developing a BB OS<7.X application, that implements push notifications. I finally ended up with some working code that is able to receive push.
However, the push notifications DONT work the first time i deploy the application on the phone. If i try to send a push on the device, after i just deployed it, when i send the push from my server, i can see on the right up corner of my device a little arrow loading , but no push message is displayed on the screen.
If i restart the device, the push notifications work properly!! Now whenever i send a push, i see the little arrow again on up right screen and the push message displayed corrected.
The code looks like this(the parts i consider important):
MyApp.java
public class MyApp extends UiApplication
{
public static void main(String[] args)
{
//every time we start the application we register to BIS for push
if (args.length > 0 && args[0].equals("BlackBerryCity")) {
System.out.println("!!!!!!!!!!!!!!I am inside if");
//registering for push
push_main.registerBpas();
MyApp app = new MyApp();
app.enterEventDispatcher();
}
//every time we restart the phone , we call this background process that is responsible for listening for push
else {
System.out.println("!!!!!!!!!!!!!!I am inside else");
//should put the background classes for listening to pushed msgs :D
BackgroundApplication backApp=new BackgroundApplication();
backApp.setupBackgroundApplication();
backApp.enterEventDispatcher();
}

On the main class , MyApp.java , as you can see everytime the application is launched, i register for push. Every time the device restarts, i start a background process to listen for push. Or at least, this is what i believe i am doing here.
Why should i do that?
I thought that by registering for push, the background listener would somehow start too... But i guess it doesn't.. That's why probably when i restart the phone, this code is executed and the push starts coming in.
How could i fix this problem so that i could start the background listener:
the first time the app is deployed
every time i restart the device
but NOT on every launch of the app.
Following is the code which is showing the above exception on debugging :
Firstly I am trying to call a class HTTPConnection from the below menu item.
protected MenuItem _SelectDealerItem = new MenuItem("Select Dealer",100,10)
{
public void run()
{
new HTTPConnection();
}
};
In HTTPConnection Class I am checking the connection type and calling another Class TSelectDealerScreen:
public class HTTPConnection {
ConnectionFactory _factory = new ConnectionFactory();
public HTTPConnection()
{
int[] _intTransports = {
TransportInfo.TRANSPORT_TCP_WIFI,
TransportInfo.TRANSPORT_WAP2,
TransportInfo.TRANSPORT_TCP_CELLULAR
};
for(int i=0;i<_intTransports.length;i++)
{
int transport = _intTransports[i];
if(!TransportInfo.isTransportTypeAvailable(transport)||!TransportInfo.hasSufficientCoverage(transport))
{
Arrays.removeAt(_intTransports,i);
}
}
TcpCellularOptions tcpOptions = new TcpCellularOptions();
if(!TcpCellularOptions.isDefaultAPNSet())
{
tcpOptions.setApn("My APN");
tcpOptions.setTunnelAuthUsername("user");
tcpOptions.setTunnelAuthPassword("password");
}
if(_intTransports.length>0)
{
_factory.setPreferredTransportTypes(_intTransports);
}
_factory.setTransportTypeOptions(TransportInfo.TRANSPORT_TCP_CELLULAR, tcpOptions);
_factory.setAttemptsLimit(5);
Thread t = new Thread(new Runnable()
{
public void run()
{
ConnectionDescriptor cd = _factory.getConnection("http://excellentrealtors.info/Smart-Trace/get_dealer.php");
if(cd!=null)
{
Connection c = cd.getConnection();
displayContent(c);
}
}
});
t.start();
}
private void displayContent(final Connection conn)
{
UiApplication.getUiApplication().pushScreen(new TSelectDealerScreen(conn));
}
}
In TSelectDealerScreen class i am simply trying to read the stream, but it is showing illegal state exception whenever i try to debug, I am not much familiar to blackberry programming, kindly advice.
public class TSelectDealerScreen extends MainScreen
{
RichTextField _rtfOutput = new RichTextField();
public TSelectDealerScreen(Connection conn)
{
_rtfOutput.setText("Retrieving Data.Please Wait");
add(_rtfOutput);

t.start();
}

ContentReaderThread(Connection conn)
{
_connection = conn;
}
public void run()
{
String result = "";
OutputStream os = null;
InputStream is = null;
try
{
OutputConnection outputConn = (OutputConnection)_connection;
os = outputConn.openOutputStream();
String getCommand = "GET " + "/" + " HTTP/1.0\r\n\r\n";
os.write(getCommand.getBytes());
os.flush();
// Get InputConnection and read the server's response
InputConnection inputConn = (InputConnection) _connection;
is = inputConn.openInputStream();
byte[] data = net.rim.device.api.io.IOUtilities.streamToBytes(is);
result = new String(data, "US-ASCII");
// is.close();
System.out.print(result);
}
catch(Exception e)
{

}
finally
{
// Close OutputStream
if(os != null)
{
try
{
os.close();
}
catch(IOException e)
{
}
}
// Close InputStream
if(is != null)
{
try
{
is.close();
}
catch(IOException e)
{
}
}
// Close Connection
try
{
_connection.close();
}
catch(IOException ioe)
{
}
}
// Show the response received from the web server, or an error message
showContents(result);
}
}
public void showContents(final String result)
{
UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
_rtfOutput.setText(result);
}
});
}
}
In your HTTPConnection class, you do:
Thread t = new Thread(new Runnable()
{
public void run()
{
ConnectionDescriptor cd = _factory.getConnection("http://excellentrealtors.info/Smart-Trace/get_dealer.php");
if(cd!=null)
{
Connection c = cd.getConnection();
displayContent(c);
}
}
});
t.start();
That runs everything inside run() on a background thread. But, inside displayContent(c), you do:
UiApplication.getUiApplication().pushScreen(new TSelectDealerScreen(conn));
which is a UI operation.
Trying to modify the UI from a background thread normally causes an IllegalStateException.
I believe you just need to wrap the call to pushScreen() with this:
private void displayContent(final Connection conn) {
final UiApplication app = UiApplication.getUiApplication();
app.invokeLater(new Runnable() {
public void run() {
// this code is run on the UI thread
app.pushScreen(new TSelectDealerScreen(conn));
}
});
}
Also, if you're an Android developer, and you want help doing normal background/UI thread stuff, you might check out this other answer I wrote on "porting" AsyncTask to BlackBerry Java
I need a sample application code for push integration in my blackberry application. I have registered my application for the push credentials and have received them.
please help,
Kind Regards,

How can I add an loading dialog to my Browserfield when the page is loading?
Thanks
Use a GaugeField: net.rim.device.api.ui.component.GaugeField,
following the example at: http://docs.blackberry.com/en/developers/deliverables/18125/Gauge_field_1303006_11.jsp
Use BrowserFieldListener and use the following two functions in the class created:
public void documentCreated(BrowserField browserField, ScriptEngine scriptEngine, Document document) {
try{
System.out.println("Document Created");
UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
Dialog.alert("Loading");
}});
} catch (Exception ex) { }
}
public void documentLoaded(BrowserField browserField, Document document) {
try {
System.out.println("Document loaded");
UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
Dialog.alert("Finished Loading");
}});
} catch (Exception ex) { }
}
