Im beginner in Flex mobile application , my issue is the app restart then i used PersistenceManager to solve it, but when i take an image with camera i cannot hold the image if the app restart then how to hold all image captured when user click to save button i think it will be in the imagecaptured method but it doesn't work the app restarted and camera app is opened to take image method is
public function imagecaptured(event:MediaEvent):void
{
//submitButton.enabled = false;
antherImg.label = "please wait to detect your location";
imagepromise = event.data;
imgBorder.source = imagepromise.file.url;
//values to send
var imgURL:Object = imagepromise.file.url;
var imgName:Object = imagepromise.relativePath;
//save Persistence
var saveManager:PersistenceManager = new PersistenceManager();
saveManager.setProperty("url", imagepromise.file.url);
saveManager.setProperty("name", imagepromise.relativePath);
}
and when page creation (creationComplete)
public var loadManager:PersistenceManager = new PersistenceManager();
if(loadManager.load())
{
var savedData:Object = saveManager.getProperty("url");
var savedData:Object = saveManager.getProperty("name");
}
Please help , Thanks in advance

I am trying to connect two Air Application using LocalConnection. It works when I open as SWF and EXE(published) but when I publish it to Air files they doesn't work. I am creating one interactive screen that send command to another Air Application(Projector). This few lines on code will only appear of "frame one".
Sending:
var sending_lc:LocalConnection;
sending_lc = new LocalConnection();
Receiving:
var receiving_lc:LocalConnection;
receiving_lc = new LocalConnection();
receiving_lc.connect("my_lc_as3");
receiving_lc.client = this;
Please refer to this doc http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/LocalConnection.html
To make LocalConnection work between AIR apps, allowDomain() needs to be called.
For example, in your case:
// For receiving_lc
// Here receiving_lc is an Air app with app Id = com.sample
receiving_lc.allowDomain('app#com.example');
receiving_lc.connect("my_lc_as3");
// For sending_lc
sending_lc.send('app#com.sample:my_conn', 'my_method');
Thank you KevinVFX and akmozo.
It's working now and this is the code.
Sending:
var sending_lc:LocalConnection;
sending_lc = new LocalConnection();
sending_lc.send("app#APPIDReceiving:my_lc_as3", "my_method");
Receiving:
var receiving_lc:LocalConnection;
receiving_lc = new LocalConnection();
receiving_lc.allowDomain("app#APPIDSending");
receiving_lc.connect("my_lc_as3");
receiving_lc.client = this;
function my_method():void{
trace("linked");

I am trying to experiment with downloading files on a regular basis with background tasks for windows store applications, and am having trouble.
I followed the sample at https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh977055.aspx, and even downloaded/ran it and everything worked perfectly (including being able to step into the timer background task).
So with that I created my own background task in a brand new Windows namespace
Win8BackgroundTest
{
public class TestBackgroundTask
{
public async void Run(IBackgroundTaskInstance taskInstance)
{
var deferral = taskInstance.GetDeferral();
var uri = new Uri("http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_h264.mov");
var folder = ApplicationData.Current.LocalFolder;
var downloadFile = await folder.CreateFileAsync(uri.Segments.Last(), CreationCollisionOption.GenerateUniqueName);
var dataFile = await folder.CreateFileAsync("downloadData", CreationCollisionOption.GenerateUniqueName);
var downloader = new BackgroundDownloader();
var operation = downloader.CreateDownload(uri, downloadFile);
await FileIO.WriteTextAsync(dataFile, "Success at " + DateTime.Now);
deferral.Complete();
}
public static async void RegisterTask()
{
const string taskName = "TestBackgroundTask";
try
{
var status = await BackgroundExecutionManager.RequestAccessAsync();
if (status == BackgroundAccessStatus.Denied)
{
return;
}
}
catch
{
// already accepted
}
var tasks = BackgroundTaskRegistration.AllTasks
.Where(x => x.Value.Name == taskName)
.ToArray();
if (tasks.Any())
{
return;
}
var builder = new BackgroundTaskBuilder
{
Name = taskName,
TaskEntryPoint = "Win8BackgroundTest.TestBackgroundTask",
};
builder.SetTrigger(new TimeTrigger(60, false));
var registeredTask = builder.Register();
}
}
}
I set up the application's manifest with a Background Tasks declaration, checking the Timer properties checkbox, and set the EntryPoint to Win8BackgroundTest.TestBackgroundTask.
I then added the following at the end of my App.xaml.cs's OnLaunched() method:
TestBackgroundTask.RegisterTask();
Stepping through seems to have task registration work successfully with no exceptions. I then go back to visual studio, added a breakpoint to the first line in my task's Run() method, I then go to the debug locations toolbar, click the down arrow and select TestBackgroundTask. A few seconds later visual studio exits (as does my app).
Does anyone see what I am doing wrong that is causing background tasks to fail?
So after much frustration and a lot of trial and error the issue was a combination of both of the comments.
So first of all, it appears like you cannot have a background task in the same project as the rest of your windows store application. It must be in it's own windows runtime component project.
Finally, there are times where it just doesn't work and for whatever reason deleting the bin and obj folders fix it.
I am building a geofencing app on Windows Phone. The current version includes about 100 geofences, some of the overlap with others. I wrote a background task and set the trigger the entered state of a geofence. When I am out, testing my app, it occurs, that the background task does not react on geofences which overlap with others.
This is the code from the backround task:
public void Run(IBackgroundTaskInstance taskInstance)
{
var reports = GeofenceMonitor.Current.ReadReports();
var report = reports.FirstOrDefault(r => (r.Geofence.Id == "testID") && (r.NewState == GeofenceState.Entered));
if (report == null) return;
var toastXmlContent = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
var txtNodes = toastXmlContent.GetElementsByTagName("text");
txtNodes[0].AppendChild(toastXmlContent.CreateTextNode("Geofence entered!"));
txtNodes[1].AppendChild(toastXmlContent.CreateTextNode(report.Geofence.Id));
var toast = new ToastNotification(toastXmlContent);
var toastNotifier = ToastNotificationManager.CreateToastNotifier();
toastNotifier.Show(toast);
}
Does anybody know, how to handle overlapping geofences on Windows Phone?
Thank you
There are quite a few Windows Phone 8.1 apps (e.g. Clock hub, Analog Clock Tile, etc.) which allow you to pin an analog clock on the main screen.
I am trying to do the same by following this sample which shows me how to update an XML document every minute.
But if I am going to create an analog clock tile then it needs to be an image.
I have tried to use XamlRenderingBackgroundTask with RenderTargetBitmap to generate the image, this bit works. What I am not sure is how can I update this image every minute.
Any help wold be greatly appreciated!
I took the sample you provided and modified it to generate a custom image live tile every minute.
I've tested it on my phone and it seems to be working OK. You might need to do more testing such as memory usage testing to make sure it doesn't go over the cap (maybe can reduce planTill to 30 minutes to generate less tiles in the loop?).
The UserControl xml file SquareFrontTile1.xml

I am not going to fully answer the question since I am myself trying to get this working at present. However I will set you in right direction. I have done this in past with windows 8.
What you need to do is create Tile Updater and schedule tiles updates every so often.. in this case one every minute. The tile schema chosen can have be image or text or a combination of both.
you can find the TileSchema catalogue here
http://msdn.microsoft.com/en-us/library/windows/apps/hh761491.aspx
and details of Tile Schema here
http://msdn.microsoft.com/en-us/library/windows/apps/br212859.aspx
Here is a Windows 8 sample
http://code.msdn.microsoft.com/windowsapps/scheduled-notifications-da477093
Here is a snippet from my code which isn't working correctly so far.. tile is blank
TileUpdater updater = TileUpdateManager.CreateTileUpdaterForApplication();
XmlDocument document = new XmlDocument();
document.LoadXml(str2);
ScheduledTileNotification notification2 = new ScheduledTileNotification(document, new DateTimeOffset(time4));
notification2.ExpirationTime = (new DateTimeOffset?((DateTimeOffset)time4.AddMinutes(1.0)));
ScheduledTileNotification notification = notification2;
updater.AddToSchedule(notification);
Once I finish this, I will write up a blog post and add a link here
I have created a repro project that tries to do this from within sample app (not background task).
http://1drv.ms/1nai8nn
The sample work for me, I add to Windows Phone Silverlight 8.1. You must change Notification Services from MPN to WNS in WMAppManifest.xml and add Background task, tick System event, Timer in Package.appxmanifest (Declarations tab).
#Justin XL: your code not work for me, error in line

Hello everyone I have a small winrt aplication that downloads video from internet and I was trying to implement backgrounddownloader and filesavepicker together but I run on errors for every type of implementation I searched google and I searched microsoft documentation but nothing.I implemented download via HttpClient class but what I want is to get download progress and HttpClient doesn't offer it.Thx in advance
Here's a quick sample, how to do it:
// set download URI
var uri = new Uri("http://s3.amazonaws.com/thetabletshow/thetabletshow_0072_lhotka.mp3");
// get destination file
var picker = new FileSavePicker();
// set allowed extensions
picker.FileTypeChoices.Add("MP3", new List<string> { ".mp3" });
var file = await picker.PickSaveFileAsync();
// create a background download
var downloader = new BackgroundDownloader();
var download = downloader.CreateDownload(uri, file);
// create progress object
var progress = new Progress<DownloadOperation>();
// attach an event handler to get notified on progress
progress.ProgressChanged += (o, operation) =>
{
// use the progress info in Progress.BytesReceived and Progress.TotalBytesToReceive
ProgressText.Text = operation.Progress.BytesReceived.ToString();
};
// start the actual download
await download.StartAsync().AsTask(progress);
You should be able to modify it for your needs from here on.
