Hi,
My Application is auto start, it shows the numbers of pending messages on HOMESCREEN with an ICON and NUMBER,
But it get updated properly when my application is in foreground ,
but when it goes to background,
and then some Message gets failed then it’s not updating the current ICON+ NUMBER instead of that it create a new ICON+ NUMBER,
Please Help me.
Here I am writing my code to set and reset...
public class IconBanner {
static EncodedImage image = null;
static ApplicationIcon appIcon = null;
static ApplicationIndicator appIndicator = null;
static ApplicationIndicator mAppIndicator = null;
static ApplicationIndicatorRegistry appIndicatorRegistry = null;
public IconBanner() {
}
/**
* Method to set banner image i.e. application icon on home screen of device.
* to show number of Unsent Email even if application is closed.
*/
public static void setBanner()
{
MailScreen mailScreen = new MailScreen(Application.getApplication());
FailedSendsSettings sendsSettings = new FailedSendsSettings(Application.getApplication());
try {
int tmp_numberOfMails = mailScreen.getNumberOfPendingMails ();// calclate no of pending message
System.out.println("Enter in setBanner " +tmp_numberOfMails);
if (image == null) {
if( tmp_numberOfMails > 0)
{
if (sendsSettings.autoOn()){
image = EncodedImage.getEncodedImageResource("yellowicon_home.png");
}
else
image = EncodedImage.getEncodedImageResource("redicon_home.png");
}
else
{
image = EncodedImage.getEncodedImageResource("greenicon_home.png");
}
}
if (appIcon == null) {
appIcon = new ApplicationIcon(image, true);
}
appIndicatorRegistry = ApplicationIndicatorRegistry.getInstance();
appIndicator = appIndicatorRegistry.register(appIcon, false, true);
mAppIndicator = appIndicatorRegistry.getApplicationIndicator();
mAppIndicator.setIcon(appIcon);
if( tmp_numberOfMails > 0)
mAppIndicator.setValue(mailScreen.getNumberOfPendingMails ());
} catch (Exception ex) {
}
}
/**
* Method to remove application icon from home screen.
*/
public static void resetBanner() {
MailScreen mailScreen = new MailScreen(Application.getApplication());
try{
if (appIndicatorRegistry != null || mAppIndicator != null) {
System.out.println("in reset banner %%%%%%%%%%%%%%%");
appIndicatorRegistry.unregister();
}
}catch(Exception e)
{}
appIndicatorRegistry = null;
mAppIndicator = null;
appIcon = null;
image = null;
}
public Bitmap getAppIconImage()
{
MailScreen mailScreen = new MailScreen(MailScreen.app.getApplication());
FailedSendsSettings sendsSettings = new FailedSendsSettings(Application.getApplication());
int tmp_numberOfMails = mailScreen.getNumberOfPendingMails ();
Bitmap iconBitmap = new Bitmap(32, 32);
Graphics g = new Graphics(iconBitmap);
EncodedImage image = null;
if( tmp_numberOfMails > 0 )
{
if (sendsSettings.autoOn())
{
image = EncodedImage.getEncodedImageResource("yellowicon.png");
}
else
{
image = EncodedImage.getEncodedImageResource("redicon.png");
}
g.drawImage(0, 0, 32, 32, image, 0, 0, 0);
g.setFont(g.getFont().derive(Font.FONT_INPUT_TEXT, Font.SIZE_SMALL));
g.setColor(Color.BLACK);
g.drawText(""+mailScreen.getNumberOfPendingMails(), 15, 23,0);
}
else //all mail sent
{
if (sendsSettings.autoOn())
{
image = EncodedImage.getEncodedImageResource("greenicon.png");
}
else
{
image = EncodedImage.getEncodedImageResource("yellowicon.png");
}
g.drawImage(0, 0, 32, 32, image, 0, 0, 0);
}
return iconBitmap;
}
}
now i am using MessageListener to call this method code is here..
public class OutboxListener implements FolderListener, MessageListener {
Message orginalMessage;
Message [] outBoxedMessage;
Message [] temp = null;
Folder messageFolder;
Folder outBox;
Store store;
public OutboxListener() {
try {
//retrieve the default message service
store = Session.getDefaultInstance().getStore();
//add the listener
store.addFolderListener(this);
calculatePendingMails();
}catch (Exception e) {
}
}
public void messagesAdded(FolderEvent folderEvent) {
orginalMessage = folderEvent.getMessage();
orginalMessage.addMessageListener(this);
messageFolder = orginalMessage.getFolder();
}
public void messagesRemoved(FolderEvent folderEvent) {
}
public void changed(MessageEvent messageEvent) {
System.out.println("changed Status of Message of ID "+orginalMessage.getMessageId() + " "+"== "+orginalMessage.getStatus());
if((orginalMessage.getStatus() == Message.Status.TX_ERROR )
|| (orginalMessage.getStatus() == Message.Status.TX_GENERAL_FAILURE))
{
IconBanner iconBanner = new IconBanner();
MailScreen mailScreen = new MailScreen(Application.getApplication());
synchronized (net.rim.device.api.system.Application
.getEventLock()) {
calculatePendingMails();
HomeScreen.updateIcon(iconBanner.getAppIconImage());
IconBanner.resetBanner();
IconBanner.setBanner();
}
}
}
public Message [] calculatePendingMails()
{
..................
// calclation code goes here
......................
return outBoxedMessage;
}
public int setPendingMails() {
return MailScreen.mPendingMails = outBoxedMessage.length;
}
}
Please help me ......
Thanks.
