I am trying to save audio at a specified device location on Button Click (which invokes run() method). This is my code.
public Audio() {
}
public void run()
{
try{
try{
_player = Manager.createPlayer("capture://audio?encoding=audio/amr");
}
catch(MediaException e)
{
Dialog.alert(e.toString());
}
_player.realize();
_rControl =(RecordControl)_player.getControl("RecordControl");
try{
**//Point 1//**_rControl.setRecordLocation("file:///Device Memory/samples/ringtones/recordTest1.amr");
}
catch(MediaException e){e.printStackTrace();}
catch(IOException e){e.printStackTrace();}
_rControl.startRecord();
_player.start();
System.out.println("<<--Successful-->>>");
}
catch(Exception e){e.printStackTrace();}
}
public void stop()
{
try{
if(_rControl != null)
{
_rControl.stopRecord();
try{
_rControl.commit();
}catch(Exception e){e.printStackTrace();}
_rControl = null;
}
if(_player != null)
{
_player.close();
_player=null;
}
}catch(Exception e){e.printStackTrace();}
}
In run() method, i am getting IOException at Point 1 where i am trying to set location for audio file. But when I tried this:
{
_rControl.setRecordLocation("file:///system/samples/ringtones/recordTest1.amr");
}
i found it working with 9550 simulator but not with 8900 simulator. So what location should i set to make this working with 8900 simulator and also 8900 blackberry device?
You should use:
javax.microedition.io.file.FileSystemRegistry.listRoots()
to get available root file systems on the device running the code.

I've been following various answers to various questions on the subject and I've come to a result and some code which looks like it works. I'm getting stuck with the NSURL part of it. I've got 2 mp3 tracks in the assets folder of my iOS gluon project. I've made the IOSAudioService Class to handle the playback. and I'm passing an argument from the play button in the view to the Play() method. Everything other than the actual file is registering as working. I'm getting an NSError, which from looking at the code is a nil value, so either the argument isn't passing correctly or it can't find the file. Code below.
public AVAudioPlayer backgroundMusic;
private double currentPosition;
NSURL songURL = null;
#Override
public void Play(String filename){
songURL = new NSURL(filename);
try {
if (backgroundMusic != null) {
Resume();
}
else {
//Start the audio at the beginning.
currentPosition = 0;
backgroundMusic = new AVAudioPlayer(songURL);
//create the mendia player and assign it to the audio
backgroundMusic.prepareToPlay();
backgroundMusic.play();}
//catch the audio error
} catch(NSErrorException e) {
System.out.println("error: " + e);
}
}
#Override
public void Stop() {
backgroundMusic.stop();
backgroundMusic = null;
}
#Override
public void Pause() {
currentPosition = backgroundMusic.getCurrentTime();
backgroundMusic.pause();
}
#Override
public void Resume() {
backgroundMusic.setCurrentTime(currentPosition);
backgroundMusic.play();
}
try {
services = (AudioService) Class.forName("com.gluonhq.charm.down.plugins.ios.IOSAudioService").newInstance();
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException ex) {
System.out.println("Error " + ex);
}
I'm getting the error at the catch block for NSExceptionError e.
if (services != null) {
final HBox hBox = new HBox(10,
MaterialDesignIcon.PLAY_ARROW.button(e -> services.Play("/audio.mp3")),
MaterialDesignIcon.PAUSE.button(e -> {
if (!pause) {
services.Pause();
pause = true;
} else {
services.Resume();
pause = false;
}
}),
MaterialDesignIcon.STOP.button(e -> services.Stop()));
//set the HBox alignment
hBox.setAlignment(Pos.CENTER);
hBox.getStyleClass().add("hbox");
//create and set up a vbox to include the image, audio controls and the text then set the alignment
final VBox vBox = new VBox(5, Image(), hBox, text1);
vBox.setAlignment(Pos.CENTER);
setCenter(new StackPane(vBox));
} else {
//start an error if service is null
setCenter(new StackPane(new Label("Only for Android")));
}
Services.get(LifecycleService.class).ifPresent(s -> s.addListener(LifecycleEvent.PAUSE, () -> services.Stop()));
}
I've also follow the advice on creating the service factory class and the interface from Audio performance with Javafx for Android (MediaPlayer and NativeAudioService) taking out the add audio element and I'm intending to do this on a view by view basis if possible.
Problem solved after must fiddling and looking in the Javadocs.Solved by adding/replacing some code with the below.
songURL = new NSURL("file:///" + NSBundle.getMainBundle().findResourcePath(filename, "mp3"));
try {
songURL.checkResourceIsReachable();}
catch(NSErrorException d) {
System.out.println("Song not found!" + d);
}
We decided to use mqtt protocol for chat module in our mobile application. I want to save messages of topic in server side also. But i saw,mqtt client is global here,so one way is i have to subscribe single instance of mqtt client to all topics and save messages in database. but is it right approach to do it. i am just worring about it.
private void buildClient(){
log.debug("Connecting... "+CLIENT_ID);
try {
mqttClient = new MqttClient(envConfiguration.getBrokerUrl(), CLIENT_ID);
} catch (MqttException e) {
log.debug("build client stopped due to "+e.getCause());
}
chatCallback = new ChatCallback();
mqttClient.setCallback(chatCallback);
mqttConnectOptions = new MqttConnectOptions();
mqttConnectOptions.setCleanSession(false);
}
#Override
public void connect() {
if(mqttClient == null || !mqttClient.getClientId().equals(CLIENT_ID)){
buildClient();
}
boolean tryConnecting = true;
while(tryConnecting){
try {
mqttClient.connect(mqttConnectOptions);
} catch (Exception e) {
log.debug("connection attempt failed "+ e.getCause() + " trying...");
}
if(mqttClient.isConnected()){
tryConnecting = false;
}else{
pause();
}
}
}
#Override
public void publish() {
boolean publishCallCompletedErrorFree = false;
while (!publishCallCompletedErrorFree) {
try {
mqttClient.publish(TOPIC, "hello".getBytes(), 1, true);
publishCallCompletedErrorFree = true;
} catch (Exception e) {
log.debug("error occured while publishing "+e.getCause());
}finally{
pause();
}
}
}
#Override
public void subscribe() {
if(mqttClient != null && mqttClient.isConnected()){
try {
mqttClient.subscribe(TOPIC, 2);
} catch (MqttException e) {
log.debug("subscribing error.."+e.getCause());
}
}
}
#Override
public void disconnect() {
System.out.println(this.mqttClient.isConnected());
try {
mqttClient.disconnect();
log.debug("disconnected..");
} catch (MqttException e) {
log.debug("erro occured while disconneting.."+e.getCause());
}
}
There are two possibilities how to solve this issue:
Write a MQTT client that subscribes to all topics using a wildcard (# in MQTT)
Write a broker plugin that does the job for you, depending on the broker implementation you're using
There is a good description of how to implement both options at the HiveMQ website, also describing limitations of the first option.
In BlackBerry, my application is working perfectly fine. But one Requirement is when I load data from server, a progress bar is showing. If it takes so much time to load data from server, then I want to stop the progress bar. In BlackBerry, on back key pressed, it is not working. Please help me.

I tried to listen file change event in BlackBerry base on FileExplorer example, but whenever I added or deleted file, it always showed "Deferring persistence as device is being used" and I can't catch anything .Here is my code:
public class FileChangeListenner implements FileSystemJournalListener{
private long _lastUSN; // = 0;
public void fileJournalChanged() {
long nextUSN = FileSystemJournal.getNextUSN();
String msg = null;
for (long lookUSN = nextUSN - 1; lookUSN >= _lastUSN && msg == null; --lookUSN)
{
FileSystemJournalEntry entry = FileSystemJournal.getEntry(lookUSN);
// We didn't find an entry
if (entry == null)
{
break;
}
// Check if this entry was added or deleted
String path = entry.getPath();
if (path != null)
{
switch (entry.getEvent())
{
case FileSystemJournalEntry.FILE_ADDED:
msg = "File was added.";
break;
case FileSystemJournalEntry.FILE_DELETED:
msg = "File was deleted.";
break;
}
}
}
_lastUSN = nextUSN;
if ( msg != null )
{
System.out.println(msg);
}
}
}
Here is the caller:
Thread t = new Thread(new Runnable() {
public void run() {
new FileChangeListenner();
try {
Thread.sleep(5000);
createFile();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
t.start();
Create file method worked fine:
private void createFile() {
try {
FileConnection fc = (FileConnection) Connector
.open("file:///SDCard/newfile.txt");
// If no exception is thrown, then the URI is valid, but the file
// may or may not exist.
if (!fc.exists()) {
fc.create(); // create the file if it doesn't exist
}
OutputStream outStream = fc.openOutputStream();
outStream.write("test content".getBytes());
outStream.close();
fc.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
and output:

I also tried to remove the thread or create or delete file in simulator 's sdcard directly but it doesn't help. Please tell me where is my problem. Thanks
You instantiate the FileChangeListenner, but you never register it, and also don't keep it as a variable anywhere. You probably need to add this call
FileChangeListenner listener = new FileChangeListenner();
UiApplication.getUiApplication().addFileSystemJournalListener(listener);
You also might need to keep a reference (listener) around for as long as you want to receive events. But maybe not (the addFileSystemJournalListener() call might do that). But, you at least need that call to addFileSystemJournalListener(), or you'll never get fileJournalChanged() called back.
I wrote the below code to send location coordinates to server:

criteria.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW);
// bc.setFailoverMode(GPSInfo.GPS_MODE_ssCDMA_MS_ASSIST, 2, 100);
try {
LocationProvider lp=LocationProvider.getInstance(criteria);
if(lp !=null)
{
Location loc=null;
// while(loc==null)
// {
loc=lp.getLocation(-1);
// }
if(loc!=null){
add(new EditField(loc.getQualifiedCoordinates().getLatitude()+"\n"+loc.getQualifiedCoordinates().getLongitude(),""));
}
else
add(new EditField("unable to find the location provider", ""));
}
else

add(new EditField("unable to find the location provider", ""));
}
} catch (LocationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ButtonField b = new ButtonField("Send");
add(b);
b.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {

I am getting an exception Critical tunnel failure. But i am able to retrieve the location coordinates correctly. I am using blackberry 8520 with airtel sim which is enabled with data services. Actually this app worked well in the mobile with version 5.0. But it's not working in the mobile which i've upgraded from 4.6.1.3 to 5.0.0 what might be the problem? Please provide me a solution. thank you
I also tried the below url's:
http://56.91.532.72:8084/SFTS/updateLocation.jsp?empid=12304&lat=16.9477&lon=82.23970;deviceside=true;apn=null
http://56.91.532.72:8084/SFTS/updateLocation.jsp?empid=12304&lat=16.9477&lon=82.23970;deviceside=true;apn=airtelgprs.com
I also enabled apn settings in my mobile
It is because you haven't set up the apn correctly. As you are using direct tcp, the apn has to be set in order to connect to the network.
Also , network connections should be done on a separate thread.
