i have tried to implement an java app which have following structure.
my problems are
when i invoke quotes thread from videoplayer thread the video still plays on top of the quotes form.
when i change video url with action event it just appends new player with current one.
ex. video2 is append along with currently running video1 when i press video 2 button
.
class VideoPlayer implements Runnable,ActionListener{
private videoappMidlet MIDlet;
VideoComponent vc;
Button Videos,quotes,video1,video2,video3;
Form videoplayer;
Thread thread;
public VideoPlayer(videoappMidlet MIDlet){
this.MIDlet = MIDlet;
}
public void run(){
try{
videoplayer=new Form();
video1=new Button("video1");
.......
vc = VideoComponent.createVideoPeer("http://localhost/video1.mpg");
vc.start();
quotes.addActionListener((ActionListener) this);
........
videoplayer.addComponent(vc);
........
videoplayer.show();
}catch(Exception error){
System.err.println(error.toString());
}
}
public void start(){
thread = new Thread(this);
try{ thread.start();}
catch(Exception error){}
}
public void actionPerformed(ActionEvent ae) {
if((ae.getSource()==Quotes))
{
Quotes tp = new Quotes(this.MIDlet);
tp.start();
}
if(ae.getSource()==video1)
{
try {
vc = VideoComponent.createVideoPeer("http://localhost/video1.mpg");
vc.start();
} catch (IOException ex) {
ex.printStackTrace();
}
}
....
}
}
class Quotes implements Runnable,ActionListener {
private videoappMidlet MIDlet;
Button Videos,quotes;
Form quote;
Thread thread;
public Quotes(videoappMidlet MIDlet){
this.MIDlet = MIDlet;
}
public void run(){
try{
quote=new Form();
Videos=new Button("Videos");
........
quote.addComponent(Videos);
........
Videos.addActionListener(this);
........
quote.show();
}catch(Exception error){
System.err.println(error.toString());
}
}
public void start(){
thread = new Thread(this);
try{ thread.start();}
catch(Exception error){}
}
public void actionPerformed(ActionEvent ae) {
if(ae.getSource()==Videos)
{
VideoPlayer vp = new VideoPlayer(this.MIDlet);
vp.start();
}
}
}
public class videoappMidlet extends MIDlet implements ActionListener{
Button play,quote;
Form home;
public void startApp() {
Display.init(this);
home=new Form();
play.addActionListener(this);
quote.addActionListener(this);
home.show();
}
public void actionPerformed(ActionEvent ae) {
if(ae.getSource()==play)
{
VideoPlayer vp = new VideoPlayer(this);
vp.start();
}
if(ae.getSource()==quote)
{
Quotes tp = new Quotes(this);
tp.start();
}
}
}
Generally video in JavaME makes no guarantee to the layer in which it is playing. LWUIT tries to seamlessly pause video player for things like a dialog on top of the UI.
As a side note LWUIT is not thread safe and you must not use a separate thread to access the UI since it will break on different platforms.

Something strange is happening.. Untill 10 minutes ago I had no problem with this code. But now I have a problem updating JUST my VBOX from an external thread.
These are my three classes:
Controller Class:
public class Controller implements Initializable{
#FXML
private VBox slaveVbox;
private ButtonBar newNode = new ButtonBar();
private Circle c= new Circle();
private Button b= new Button();
private Label lname = new Label();
private Label lIMEI = new Label();
private Label lroot = new Label();
#Override
public void initialize(URL location, ResourceBundle resources) {
}
public void create(String imei, String permission,boolean isOnline) throws IOException{
if(!alreadyExist(imei)){
newNode = new ButtonBar();
b = setButtonSpec(imei + "btnHavefun");
c = setCircleSpec(imei + "statuOnline", isOnline);
lname= setLNameSpec(imei + "name");
lIMEI = setLIMEISpec(imei + "Imei");
lroot = setLrootSpec(imei + "root", permission);
newNode.getButtons().addAll(lname,lIMEI,lroot,b,c);
slaveVbox.getChildren().addAll(newNode);
}
}
}
Main Class:
public class MainApp extends Application {
FXMLLoader loader2;
private Stage primaryStage;
private BorderPane rootLayout;
#Override
public void start(Stage primaryStage) throws IOException {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Thypheon Application");
initRootLayout();
Controller controller2 = initDesign();
Connection con = new Connection(controller2);
Thread t = new Thread(con);
t.start();
primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
#Override
public void handle(WindowEvent e) {
Platform.exit();
System.exit(0);
}
});
}
public static void main(String[] args) {
launch(args);
}
public void initRootLayout(){
try {
FXMLLoader loader = new FXMLLoader(getClass().getResource("RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public Controller initDesign(){
try {
FXMLLoader loader2= new FXMLLoader(getClass().getResource("Design.fxml"));
AnchorPane anchor = (AnchorPane) loader2.load();
rootLayout.setCenter(anchor);
Controller controller = loader2.getController();
return controller;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
public Stage getPrimaryStage(){
return primaryStage;
}
}
Connection THREAD:
public class Connection implements Runnable {
String result;
Controller controller;
public Connection(Controller controller) {
this.controller = controller;
}
#Override
public void run() {
try {
controller.create("jhgjhgjh", "dssf", true);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Debugging the Application Everything works perfectly untill I reach slaveVbox.getChildren().addAll(newNode); Here comes the exception..
After some attempt to solve the problem I figured out that if I create a ButtonBar and I insert it in the slaveVbox from Main (inside start()) it works fine.. So I ve tied to add controller2.create("FIRST", "FIRST", true); in my start() function like this:
#Override
public void start(Stage primaryStage) throws IOException {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Thypheon Application");
initRootLayout();
Controller controller2 = initDesign();
controller2.create("FIRST", "FIRST", true);
Connection con = new Connection(controller2);
Thread t = new Thread(con);
t.start();
primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
#Override
public void handle(WindowEvent e) {
Platform.exit();
System.exit(0);
}
});
}
But obviously my application shows two ButtonBars... One created in the start() function and one created inside the Connection Thread.. How Can I avoid this?? Why I can't directly add item inside my VBox directly from my Connecton thread??
You cannot update the UI from a thread other than the FX Application Thread. See, for example, the "Threading" section in the Application documentation.
It's not at all clear why you are using a background thread at all here: there doesn't seem to be any long-running code in the method you are calling. In general, if you have long-running code to call, you can call it in a background thread and then update the UI by wrapping UI update in a Platform.runLater(...).
public class Connection implements Runnable {
String result;
Controller controller;
public Connection(Controller controller) {
this.controller = controller;
}
#Override
public void run() {
try {
// execute long-running code here...
// perform any updates to the UI on the FX Application Thread:
Platform.runLater(() -> {
// code that updates UI
});
// more long-running code can go here...
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Is it possible to get the value of phobe in-call volume from java me midlet? Changing of the volume is not necessary.
Thanks.
AFAIK,
It is not possible to access the phone volume. But you can set your application volume or get the application.
Sample code for Controlling the volume of your application :
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.Ticker;
import javax.microedition.media.*;
public class VolumeControlDemo extends MIDlet implements CommandListener {
private Display display;
private Command exit,incr,decr;
Form frm;
VolumeControl vc;
int vol;
Player player;
public VolumeControlDemo() {
display = Display.getDisplay(this);
}
public void startApp() {
frm=new Form("VolumeControlDemo Demo");
exit= new Command("Exit",Command.EXIT,1);
decr= new Command("Decrease",Command.EXIT,1);
incr= new Command("Increase",Command.EXIT,1);
frm.addCommand(exit);
frm.addCommand(decr);
frm.addCommand(incr);
frm.setCommandListener(this);
display.setCurrent(frm);
try {
// Creating player object
player = Manager.createPlayer("/demo.wav");
// Setting loop count
player.setLoopCount(-1);
// Start sound
player.start();
Control cs[];
// Getting Controls object
cs = player.getControls();
for (int i = 0; i < cs.length; i++) {
if (cs[i] instanceof VolumeControl)
// Getting volume control
vc=(VolumeControl)cs[i];
}
} catch (Exception e) {}
}
public void pauseApp() {
}
public void destroyApp(boolean un) {
}
public void commandAction(Command cmd,Displayable d) {
try {
if(decr) {
if(vol>0) vol--;
vc.setLevel(vol);
} else if() {
if(vol<99) vol--;
vc.setLevel(vol);
}
frm.appent("vol="+vc.getLevel());
}catch(Exception e){}
}
}
I am working on audio recording in Nokia S40 series mobiles. I am able to record the message, but I am not able to play the recorded audio message.
Can anyone help me how to code for voice player for recorded .amr audio files?
Did any one come across this issue?
Here is my working example of recording and playing sound,
public class VoiceRecordMidlet extends MIDlet {
private Display display;
public void startApp() {
display = Display.getDisplay(this);
display.setCurrent(new VoiceRecordForm());
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
notifyDestroyed();
}
}
class VoiceRecordForm extends Form implements CommandListener {
private StringItem message;
private StringItem errormessage;
private final Command record, play;
private Player player;
private byte[] recordedAudioArray = null;
public VoiceRecordForm() {
super("Recording Audio");
message = new StringItem("", "Select Record to start recording.");
this.append(message);
errormessage = new StringItem("", "");
this.append(errormessage);
record = new Command("Record", Command.OK, 0);
this.addCommand(record);
play = new Command("Play", Command.BACK, 0);
this.addCommand(play);
this.setCommandListener(this);
}
public void commandAction(Command comm, Displayable disp) {
if (comm == record) {
Thread t = new Thread() {
public void run() {
try {
player = Manager.createPlayer("capture://audio");
player.realize();
RecordControl rc = (RecordControl) player.getControl("RecordControl");
ByteArrayOutputStream output = new ByteArrayOutputStream();
rc.setRecordStream(output);
rc.startRecord();
player.start();
message.setText("Recording...");
Thread.sleep(5000);
message.setText("Recording Done!");
rc.commit();
recordedAudioArray = output.toByteArray();
player.close();
} catch (Exception e) {
errormessage.setLabel("Error");
errormessage.setText(e.toString());
}
}
};
t.start();
}
else if (comm == play) {
try {
ByteArrayInputStream recordedInputStream = new ByteArrayInputStream(recordedAudioArray);
Player p2 = Manager.createPlayer(recordedInputStream, "audio/basic");
p2.prefetch();
p2.start();
} catch (Exception e) {
errormessage.setLabel("Error");
errormessage.setText(e.toString());
}
}
}

How to Implement a MIDlet that gets invoked when a SMS is sent to port 50000?
The code is not working. SMS can't be received on the phone, SMS is sent through the emulator (JAVA Me SDK).
What settings should be done to receive the SMS ?
my code:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
import java.io.IOException;
import javax.microedition.io.PushRegistry;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.MIDlet;
/**
* #author bonni
*/
public class Midletsms extends MIDlet implements CommandListener{
protected Display display;
//boolean started=false;
Form form = new Form("Welcome");
Command mCommandQuit;
public void startApp() {
String url = "sms://:50000";
try {
PushRegistry.registerConnection(url,this.getClass().getName(), "*");
// PushRegistry.registerConnection(url,"Midletsms.class", "*");
} catch (IOException ex) {
} catch (ClassNotFoundException ex) {
}
form.append("This midlet gets invoked when message is sent to port:50000");
display = Display.getDisplay(this);
display.setCurrent(form);
mCommandQuit = new Command("Quit", Command.EXIT, 0);
form.addCommand(mCommandQuit);
form.setCommandListener(this);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
public void commandAction(Command c, Displayable d) {
// throw new UnsupportedOperationException("Not supported yet.");
String label = c.getLabel();
if(label.equals("Quit"))
{
destroyApp(false);
notifyDestroyed();
}
}
}
Not sure I fully understand the problem. But you need to read about PushRegistry.
So there are two types of push registration, static and dynamic.
The code example you have given uses dynamic registration. You will need to manually invoke this MIDlet at least once in order for the push registration to happen. (Aside: In your example you are doing this in the startApp method, this is a very bad idea! Push registration is a potentially blocking operation, and therefore should not be done in a lifecycle method such as startApp. You should do this in a new thread).
The alternative is static registration, where you include the push information in the jad. The push port will be registered when the MIDlet is installed, without the need to run it.
Finally, you say
sms is sent through the emulator
what does this mean? In order for the app to start you need to send an SMS on the relevant port number from another MIDlet (this could be on the same handset if you want).
I found this code on net from Jimmy's blog and it is perfectly working. You can try it your self,
SMSSender.java
public class SMSSender extends MIDlet implements CommandListener {
private Form formSender = new Form("SMS Sender");
private TextField tfDestination = new TextField("Destination", "", 20, TextField.PHONENUMBER);

formSender.append(tfPort);
formSender.append(tfMessage);
formSender.addCommand(cmdSend);
formSender.addCommand(cmdExit);
formSender.setCommandListener(this);
display = Display.getDisplay(this);

UPDATE:
My Requirement is to display two Rss files as Tabs on my LWUIT Form
Initially by default first Rss file titles and images should be displayed on first tab
if an end user click on second tab,we should be able to load the second rss file titles and images
I am able to load first Rss File titles,but i am not able to load the second tab if i click on it
How to capture the click event for LWUIT Tab?
Here my code which is not working:
String topNewsurl="TopNews.rss";
String topStoryurl="TopStory.rss";
public class XMLMidlet extends MIDlet{

topnews.addElement(newsItem);
newsList.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
List source = (List) ae.getSource();

if (selectedNewsItem != null) {
displayCompleteNewsScreen(selectedNewsItem);
}
}
});
form1.show();
}
public void keyReleased(int keyCode) {
System.out.println("str");
Component p=this.getFocused();
String str= p.getClass().getName();
if(str.toLowerCase().indexOf("radiobutton")!=-1){
process();
}
From the very vague question it seems you want to capture key presses on a LWUIT Form.
jobsForm.addGameKeyListener(Display.GAME_FIRE,
new ActionListener() {
public void actionPerformed(ActionEvent evt) {
//do something here
}
});
jobsForm.addPointerPressedListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
pointer_click = true;
}
});
jobsForm.addPointerReleasedListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if (pointer_click) {
//
}
pointer_click = false;
}
});
jobsForm.addPointerDraggedListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
//System.out.println("POINTER DRAGGED");
pointer_click = false;
}
});
