How can i get call log in JavaME by ApiBridge? - java-me

I'm trying to read SMS inbox with JavaME. I tried ApiBridge, reserached the developer.nokia and I found some examples. I tried examples but i think code doesn't get the call log, just looping.
Thanks for your helps.
Here is my sample code.
APIBridge bridge = APIBridge.getInstance();
bridge.Initialize(this);
final LoggingService service = (LoggingService)bridge.createService("service.logging");
formum.append("Başlıyor\n");
Thread thread = new Thread() {
public void run() {
try {
BridgeResult res = service.GetList();
Vector returnValues = (Vector) res.getReturnValue();
String out = "Result: \n";
for (int i = 0; i < 2; i++) {
System.out.println("BridgeResult CallLog");
Hashtable item = (Hashtable) (returnValues.elementAt(i));
out += "PhoneNumber: " + item.get("PhoneNumber").toString() + "\n";
}
formum.append(out);
} catch (BridgeException ex) {
tbox.setString("Bridge error occured - unable to retrieve data. " + ex.getMessage());
} catch (Exception ex) {
tbox.setString("General error occured - unable to retrieve data. " + ex.getMessage());
}
}
};
thread.start();
And the sample code is here : http://www.developer.nokia.com/Community/Wiki/J2ME_Api_Bridge_Interface

API Bridge API is a Symbian specific solution which requires you to install both a native Symbian application the /APIBridge Installer/APIBridge_v1_1.sis on the downloaded zip. The APIBridge.jar works against the interfaces provided by APIBridge_v1_1.sis.
Since this is a Nokia Symbian specific solution it does not work for other mobile OSes and manufacturers.

Is it possable to call a method that takes this.Handle as an argument inside a background worker in C#

I am working on a stand-alone WinForm program in C# that uses the Solidworks EPDM api. The program takes a top level assembly and finds all the referenced and referencing files in the assembly. e.g. all sub-assemblies, part files, and drawings. The program then checks out all the files from EPDM, updates the data cards, and checks in all the files back to the EPDM.
I have successfully implemented the portion of the code that finds all the referenced and referencing files and updates the data card information using a background worker. This portion of the code does not require access the the UI thread. I would like to be able to add the code that checks out the files and checks them back in within a background worker. The problem is that the methods used to do the checkout and check-in take this.Handle as an argument. I know that accessing the UI thread from within a background worker will throw a cross thread exception. The code does not access any of the UI controls. It only need access to this.Handle. Is it possible to pass this.Handle to a background worker in a thread safe way that will not throw a cross thread exception?
This is my first use of background workers so my knowledge is limited. Below is the code that I would like to run in a background worker.
private void BatchCheckout(Dictionary<string, string> SelectedFiles)
{
try
{
IEdmBatchGet batchGetter = (IEdmBatchGet)vault.CreateUtility(EdmUtility.EdmUtil_BatchGet);
EdmSelItem[] ppoSelection = new EdmSelItem[SelectedFiles.Count];
IEdmFile5 aFile;
IEdmFolder5 aFolder;
IEdmFolder5 ppoRetParentFolder;
IEdmPos5 aPos;
int i = 0;
foreach (KeyValuePair<string, string> kvp in SelectedFiles)
{
aFile = vault1.GetFileFromPath(kvp.Key, out ppoRetParentFolder);
aPos = aFile.GetFirstFolderPosition();
aFolder = aFile.GetNextFolder(aPos);
ppoSelection[i] = new EdmSelItem();
ppoSelection[i].mlDocID = aFile.ID;
ppoSelection[i].mlProjID = aFolder.ID;
i = i + 1;
}
batchGetter.AddSelection((EdmVault5)vault1, ref ppoSelection);
batchGetter.CreateTree(this.Handle.ToInt32(), (int)EdmGetCmdFlags.Egcf_Lock);
batchGetter.GetFiles(this.Handle.ToInt32(), null);
}
catch (System.Runtime.InteropServices.COMException ex)
{
MessageBox.Show("HRESULT = 0x" + ex.ErrorCode.ToString("X") + " " + ex.Message);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n" + GetStackTrace(ex));
}
}
I have been a reader of StackOverflow for many years and have found answers to just about every question I have ever had. This is my first ever question on StackOverflow. I am really hoping that someone will have an answer to this problem.
EDIT:
I have successfully test AndrewK's suggestion and am happy to report that it did work for my batch checkout method. When I run my batch check-in method in a background worker I'm getting the following COM exception:
Unable to cast COM object of type 'System.__ComObject' to interface type 'EPDM.Interop.epdm.IEdmBatchUnlock2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{F0970446-4CBB-4F0F-BAF5-F9CD2E09A5B3}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
I only get this exception if I run the code from a background worker.
Here is the code from my BatchCheckin method:
private void BatchCheckin(Dictionary<string, string> SelectedFiles)
{
try
{
int i = 0;
IEdmFolder5 ppoRetParentFolder;
IEdmFile5 aFile;
IEdmFolder5 aFolder;
IEdmPos5 aPos;
EdmSelItem[] ppoSelection = new EdmSelItem[SelectedFiles.Count];
IEdmBatchUnlock2 batchUnlock;
foreach (KeyValuePair<string, string> kvp in SelectedFiles)
{
aFile = vault5.GetFileFromPath(kvp.Key, out ppoRetParentFolder);
aPos = aFile.GetFirstFolderPosition();
aFolder = aFile.GetNextFolder(aPos);
ppoSelection[i] = new EdmSelItem();
ppoSelection[i].mlDocID = aFile.ID;
ppoSelection[i].mlProjID = aFolder.ID;
i = i + 1;
}
batchUnlock = (IEdmBatchUnlock2)vault7.CreateUtility(EdmUtility.EdmUtil_BatchUnlock);
batchUnlock.AddSelection((EdmVault5)vault5, ref ppoSelection);
batchUnlock.CreateTree(0, (int)EdmUnlockBuildTreeFlags.Eubtf_ShowCloseAfterCheckinOption + (int)EdmUnlockBuildTreeFlags.Eubtf_MayUnlock);
batchUnlock.Comment = "Updates";
batchUnlock.UnlockFiles(0, null);
}
catch (System.Runtime.InteropServices.COMException ex)
{
MessageBox.Show("HRESULT = 0x" + ex.ErrorCode.ToString("X") + " " + ex.Message);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n" + GetStackTrace(ex));
}
}
I am getting the exception when I make the call to vault7.CreateUtility. The BatchCheckin code is nearly identical to the BatchCheckout. I'm making the same call to vault7.CreateUtility in both methods. The only difference is the EdmUtility flag is set to EdmUtil_BatchUnlock in the BatchCheckin method. Any clue on this one AndrewK?
UPDATE:
I was able to resolve the COM exception by changing batchUpdate from the IEdmBatchUnlock2 interface to the IEdmBatchUnlock interface. Here is the code change:
private void BatchCheckin(Dictionary<string, string> SelectedFiles)
{
int i = 0;
IEdmFolder5 ppoRetParentFolder;
IEdmFile5 aFile;
IEdmFolder5 aFolder;
IEdmPos5 aPos;
EdmSelItem[] ppoSelection = new EdmSelItem[SelectedFiles.Count];
IEdmBatchUnlock batchUnlock = (IEdmBatchUnlock)vault7.CreateUtility(EdmUtility.EdmUtil_BatchUnlock);
try
{
foreach (KeyValuePair<string, string> kvp in SelectedFiles)
{
aFile = vault5.GetFileFromPath(kvp.Key, out ppoRetParentFolder);
aPos = aFile.GetFirstFolderPosition();
aFolder = aFile.GetNextFolder(aPos);
ppoSelection[i] = new EdmSelItem();
ppoSelection[i].mlDocID = aFile.ID;
ppoSelection[i].mlProjID = aFolder.ID;
i = i + 1;
}
batchUnlock.AddSelection((EdmVault5)vault5, ref ppoSelection);
batchUnlock.CreateTree(0, (int)EdmUnlockBuildTreeFlags.Eubtf_ShowCloseAfterCheckinOption + (int)EdmUnlockBuildTreeFlags.Eubtf_MayUnlock);
batchUnlock.Comment = "Release to Production ECO";
batchUnlock.UnlockFiles(0, null);
}
catch (System.Runtime.InteropServices.COMException ex)
{
MessageBox.Show("HRESULT = 0x" + ex.ErrorCode.ToString("X") + " " + ex.Message);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n" + GetStackTrace(ex));
}
}
I am guessing that this is a bug in the IEdmBatchUnlock2 interface. The IEdmBatchUnlock2 will cause a COM exception if called from a background worker but will not cause a COM exception if called from the UI thread. The IEdmBatchUnlock interface will not cause a COM exception when called from a background worker.
Just put a 0 in there for the handle. As long as your code will not require user input, it will work. I do it often.
batchGetter.AddSelection((EdmVault5)vault1, ref ppoSelection);
batchGetter.CreateTree(0, (int)EdmGetCmdFlags.Egcf_Lock);
batchGetter.GetFiles(0, null);

My app crashes when I try to send a request to the server

Well, it actually works pretty well on my android studio simulator but when I try to run it on my phone it just crashes.
I just want to send a number to the server and get a response with the data that I need to that number. so this is my code which do that:
thread = new Thread() {
#Override
public void run() {
//server stuff
try {
//Connecting
if(!userClass.equals("")) {
Log.i(debugString, "Attempting to connect to server");
socket = new Socket(hostname, portnumber);
Log.i(debugString, "Connection established!");
BufferedWriter bw = new BufferedWriter((new OutputStreamWriter(socket.getOutputStream())));
bw.write("" + userClass);
bw.newLine();
bw.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
input = br.readLine();
}
} catch (IOException e) {
Log.e(debugString, e.getMessage());
} finally {
threadComplete = true;
}
}
};
thread.start();
while(!threadComplete)
continue;
then I just use this thread whenever I want to get the updated info for my request like that:
String getUserClass = userClass;
if(!getUserClass.equals(""))
{
threadComplete = false;
userClass = getUserClass;
thread.start();
while (!threadComplete)
continue;
changes.setText(input);
}
else Toast.makeText(this, "Error, choose your class", Toast.LENGTH_SHORT).show();
BTW, in the end of every thread (on the emulator because on my phone it crashes) I get a message:
Skipped 91 frames! The application may be doing too much work on its main thread.
and I have another problem, I also use IntentService to run my app service on the background, and obviously I don't want it to run constantly forever, so I made a loop which contains at the end of each loop a wait() command, but the problem is that when I set the time to wait for longer than 3000 milliseconds or so, the service crashes.
my code for the background service:
synchronized (this) {
int count = 0;
while (count<4) {
try {
wait(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
if (notifications && !userClass.equals("")) {
new Thread() {
#Override
public void run() {
//server stuff
try {
//Connecting
if (!userClass.equals("")) {
Log.i("debug", "Attempting to connect to server");
socket = new Socket(hostname, portnumber);
Log.i("debug", "Connection established!");
BufferedWriter bw = new BufferedWriter((new OutputStreamWriter(socket.getOutputStream())));
bw.write("" + userClass);
bw.newLine();
bw.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
input = br.readLine();
}
} catch (IOException e) {
Log.e("debug", e.getMessage());
} finally {
complete = true;
}
}
}.start();
while (!complete)
continue;
Toast.makeText(this, "" + input, Toast.LENGTH_SHORT).show();
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.chanka)
.setContentTitle("ביטול שיעורים: ")
.setContentText(input);
mNotifyMgr.notify(mNotificationId, mBuilder.build());
mNotificationId++;
Toast.makeText(this, "" + input, Toast.LENGTH_SHORT).show();
count++;
}
}
}
This following piece of code is the culprit -
while (!threadComplete)
continue;
You are kind of putting the main thread on a long loop. Android does not allow that. The general construct in these kind of use cases is this -
Step 1 - Show a progress dialog to the user indicating that you are
doing something important and user needs to wait till that is
complete. Show some meaningful text in the progress dialog which makes
sense to the user.
Step 2 - Start a async connection to the server. There are lot of
options in Android to do this. But for your purpose AsyncTask might
be useful. Connect to your server, fetch and parse data in the
doInBackground method of AsyncTask and once the task is complete,
let onPostExecute publish the same to the Main thread.
Step 3 - Once you get back the result from the Async task, you may
dismiss the progress dialog and continue with whatever you were doing.
Please note that the main thread should not be blocked at any time. This is the event handling thread of the app and handles all events (User initiated or system initiated). If the thread is blocked, you get the kind of error you are seeing now. Specifically in your case, Android system is not able to do some draw operations because of the while loop.
Create a new Asynctask and run the socket establisment codes inside it :)
socket = new Socket(hostname, portnumber);

NetMQ in Publisher and subscriber not working

I'm trying to implement the NetMQ Pub/Sub Model, but the Subscriber is not receiving any messages. What possibly is wrong here?
private static void ServerTask()
{
using (var context = NetMQContext.Create())
{
using (var socket = context.CreateSubscriberSocket())
{
socket.Bind("tcp://10.120.19.109:5000");
socket.Subscribe(string.Empty);
while (true)
{
Thread.Sleep(100);
string receivedMessage = socket.ReceiveString();
Console.WriteLine("Received: " + receivedMessage);
}
}
}
}
public static void ClientTask()
{
using (NetMQContext ctx = NetMQContext.Create())
{
using (var socket = ctx.CreatePublisherSocket())
{
socket.Connect("tcp://10.120.19.109:5000");
string obj = "hi";
socket.Send(obj);
}
}
}
Both are in different apps.
If you are new to NetMQ I suggest reading the zeromq guide http://zguide.zeromq.org/page:all.
Bottom line is that you are sending the message before the subscriber sent the subscription.
Pubsub in zeromq and NetMQ is like radio, you will only get messages from the moment you start listen.
To simple way to do it (not a real life solution) is to sleep for some time after the connect.
For real life solution I need to understand what are you trying to achieve
issue is like
using (NetMQContext ctx = NetMQContext.Create())
{
using (var publisher = ctx.CreatePushSocket())
{
publisher.Bind("tcp://localhost:5000");
int i = 0;
while (true)
{
try
{
publisher.Send(i.ToString(), dontWait:true);
Console.WriteLine(i.ToString());
}
catch (Exception e)
{
}
finally
{
i++;
}
}
}
Now , this code works. But if I move my while(true) loop outside. and call this code from some other function Which forces push socket and context to be created as new everytime.. this doesnot work.

LWUIT4IO (v1.5) ConnectionRequest's readResponse() Issue - Nokia SDK 2.0

I have been porting an existing J2ME mobile app, that allows users to view archived news videos, to the latest Nokia SDK 2.0 platform for Series 40 full-touch devices.
I am using both the LWUIT and LWUIT4IO technologies for the UI and Network functionalities of the application respectively.
The app has been tested to work on the S40 5th Edition SDK platform emulator. Extending LWUIT4IO's ConnectionRequest class and utilizing LWUIT's XMLParser, the app can successfully send a HTTP request and get the expected response data from a web service that basically returns an XML-formatted type of feed (containing necessary metadata for the video) (Here's the URL of the web service: http://nokiamusic.myxph.com/nokianewsfeed.aspx?format=3gp)
But for some reason, this is not the case when trying to run the app on the latest Nokia SDK 2.0 platform. It throws a java.lang.NullPointerException upon trying to parse (XMLParser.parse()) the InputStream response of the web service. When I trace the Network Traffic Monitor of the emulator of the corresponding Request sent and Response received - 0 bytes were returned as content despite a successful response status 200. Apparently the XMLParser object has nothing to parse in the first place.
I am hoping that you can somehow shed light on this issue or share any related resolutions, or help me further refine the problem.
Posted below is the code of the SegmentService class (a sub-class of LWUIT's ConnectionRequest) that connects to the webservice and processes the XML response:
public class SegmentService extends ConnectionRequest implements ParserCallback {
private Vector segments;
private Video segment;
public SegmentService(String backend) {
String slash = backend.endsWith("/") ? "" : "/";
setPost(false);
setUrl(backend + slash + "nokianewsfeed.aspx");
addArgument("format", "3gp");
}
public void setDateFilter(String date) {
System.out.println(date);
addArgument("date", date);
}
private Video getCurrent() {
if (segment == null) {
segment = new Video();
}
return segment;
}
protected void readResponse(InputStream input) throws IOException {
InputStreamReader i = new InputStreamReader(input, "UTF-8");
XMLParser xmlparser = new XMLParser();
System.out.println("Parsing the xml...");
Element element = xmlparser.parse(i);
System.out.println("Root " + element.getTagName());
int max = element.getNumChildren();
System.out.println("Number of children: " + max);
segments = new Vector();
for (int c = 0; c < max; c++) {
Element e = element.getChildAt(c);
System.out.println("segment " + c);
int len = e.getNumChildren();
System.out.println("Number of children: " + len);
for (int d=0; d<len; d++) {
Element s = e.getChildAt(d);
String property = s.getTagName();
System.out.println("key: " + property);
String value = (s.getNumChildren()>0) ? s.getChildAt(0).getText() : null;
System.out.println("value: " + value);
if (property.equals("title")) {
getCurrent().setTitle(value);
} else if (property.equals("description")) {
getCurrent().setDescription(value);
} else if (property.equals("videourl")) {
getCurrent().setVideoUrl(value);
} else if (property.equals("thumburl")) {
getCurrent().setThumbUrl(value);
} else if (property.equals("adurl")) {
getCurrent().setAdUrl(value);
} else if (property.equals("publishdate")) {
getCurrent().setPublishDate(value);
} else if (property.equals("category")) {
getCurrent().setCategory(value);
} else if (property.equals("weburl")) {
getCurrent().setWebUrl(value);
} else if (property.equals("thumburl2")) {
getCurrent().setThumb210(value);
} else if (property.equals("thumburl4")) {
getCurrent().setThumb40(value);
}
}
if (segment != null) {
segments.addElement(segment);
segment = null;
}
}
fireResponseListener(new NetworkEvent(this, segments));
}
public boolean parsingError(int errorId, String tag, String attribute, String value, String description) {
System.out.println(errorId);
System.out.println(tag);
System.out.println(value);
System.out.println(description);
return true;
}
}

Calling Console Application (.exe) in Event Receiver and Getting Error

I am using SharePoint foundation. I have a console application that is used to run some OCR process. I am calling the exe of the console application from windows service and it is working fine. I am trying to call the same exe from an event receiver but unable to call the exe and getting some error. The Event receiver is working fine but unable to call exe. I have tried to call the other exes like notepad.exe but getting same error. The details are below:
Code:
public override void ItemAdded(SPItemEventProperties properties)
{
try
{
base.ItemAdded(properties);
Log("Event Occured.");
string OCRedText = string.Empty;
string Listname = properties.ListTitle;
string itemName = Convert.ToString(properties.ListItem["Name"]);
string itemTitle = Convert.ToString(properties.ListItem["Title"]);
callService(); // Here is the method to call Process
SPListItem item = properties.ListItem;
if (System.Threading.Monitor.TryEnter(myLock, TimeSpan.FromSeconds(100)))
{
if (Convert.ToString(item["OCRed"]) == "False")
{
item["OCRed"] = "True";
Thread.Sleep(10000);
item.SystemUpdate();
Log("Item Added and Updated.");
}
else
{
Log("Can not update the Item.");
}
}
Log("Event End."+"\r\n");
}
catch (Exception ex)
{
Log("Error in Item Added Event Receiver.");
Log(ex.ToString());
}
}
public void callService()
{
Log("Calling Service is not easy.");
try
{
ProcessStartInfo pinfoService = new ProcessStartInfo();
pinfoService.FileName = #"D:\Khan\khan.exe";
//pinfoService.FileName = #"C:\Windows\System32\notepad.exe";
pinfoService.UseShellExecute = false;
pinfoService.RedirectStandardError = true;
pinfoService.RedirectStandardInput = true;
pinfoService.RedirectStandardOutput = true;
pinfoService.CreateNoWindow = true;
pinfoService.WindowStyle = ProcessWindowStyle.Hidden;

Process pService = new Process();
pService.StartInfo = pinfoService;
Log("Process Before Start.");
Thread.Sleep(5000);
pService.Start();
Thread.Sleep(2000);
Log("Process Before wait for exit.");
pService.WaitForExit();
Log("Process Completed.");
}
catch (Exception ex)
{
Log("Error in callService(). Please contact your Administrator.");
Log(ex.ToString());
}
}
and below is the error I am getting on pService.Start();
=========================================
Info : Process Before Start.

=========================================
I am unable to figure out the issue. Please help me...!!!
Thanks in Advance.

I think that the asp.net account under which the application pool runs does not have permissions to start the exe file. You can check this out http://www.daniweb.com/web-development/aspnet/threads/386380/cannot-run-exe-files-in-asp.net-application
However if your system will be used by more users you can run into problems really quickly, because every change of a document will spawn a new process. The server will run out of ram and the farm will not be unavailable.
