In my balckberry application i am using the Persistance,List and Threads to execute the code.
The code is given below:
enter code here
UiApplication.getUiApplication().invokeLater(new Runnable(){
public void run(){
CategoryListScreen.getInstance(
UiApplication.getUiApplication())
.setCategoryListContent();
}
});
public void setCategoryListContent() {
categoryList.delete(0);
CategoryListScreen categoryListScreen = CategoryListScreen
.getInstance(UiApplication.getUiApplication());
PersistentObject categoryListPersistObject = PersistentStore
.getPersistentObject(0x73c8d3592648fea5L);
PersistentObject datePersistObject = PersistentStore
.getPersistentObject(0xe453c1c0c14b9aebL);
categoryListPersistObject.setContents(Communicator.categoryDatas);
datePersistObject.setContents(new Date());
categoryListScreen.setCategoryListVector(new Vector());
categoryDataList = Communicator.categoryDatas;
System.out.println("-------------------- " + Communicator.categoryDatas.length);
for (int i = 0; i < Communicator.categoryDatas.length; i++) {
if (Communicator.categoryDatas[i] != null) {
if (Communicator.categoryDatas[i].getName() != null) {
categoryListScreen.getCategoryListVector().addElement(
Communicator.categoryDatas[i].getName());
}
}
}
testListCallback = new ListCallback();
categoryList.setCallback(testListCallback);
int i = categoryListScreen.getCategoryListVector().size();
categoryListScreen.getCategoryList().setSize(i);
System.out.println("---------------------->" + categoryListScreen.getCategoryListVector().size());
//
categoryListScreen.getCategoryList().setRowHeight(40);
// categoryListScreen.invalidate();
invalidate();
System.out.println("End.........................");
}
The application is Using the Threads to execute the persistance and also setting the size of the list.The application is running fine and exiting successfully.
But at the time of unistalling the application the device get being restarted and also after restarting the application ,there is no effect on the application.The application still remains there.
what is the problem in uinstalling the application which uses Threads,persistance and list?
why is it being restarted without any user confirmation or alert?
why is it not get being uninsall after restart?
please give the resolution for the given problem or any useful code snippet ,which would be appreciated.
Thanks,
Mishal Shah
Is this on a device simulator or a real device? As far as I know, if you reset the simulator, it loads back all the installed apps onto to simulator.

i'm using an Iphone 10 with ios 15.3.1,Zxing version = 2.4.1, compiling the xamarin project in windows. I been trying to make a qr scanner with zxing for ios android, but when i run my app in ios, it won't go to the onResult event. I've tried with a lot of methods of doing this, but nothing seems to work. The camera shows, but the result never comes truh. ¿Does someone have any idea why this is happening? I also tried apps from other devs that are using zxing and it also dosen't work. but when i scan with the camera app it works.
async void OnButtonClickedAsync(object sender, System.EventArgs e)
{
var options = new ZXing.Mobile.MobileBarcodeScanningOptions
{
CameraResolutionSelector = HandleCameraResolutionSelectorDelegate
};
MobileBarcodeScanner scanner = new MobileBarcodeScanner();
//scanner.TopText = "Hold camera up to barcode to scan";
//scanner.BottomText = "Barcode will automatically scan";
//scanner.UseCustomOverlay = false;
scanner.FlashButtonText = "Flash";
scanner.CancelButtonText = "Cancel";
scanner.Torch(true);
scanner.AutoFocus();
var result = await scanner.Scan(options);
HandleScanResult(result);
}
void HandleScanResult(ZXing.Result result)
{
if (result != null && !string.IsNullOrEmpty(result.Text))
scanResultText.Text = result.Text;
}
CameraResolution HandleCameraResolutionSelectorDelegate(List<CameraResolution> availableResolutions)
{
//Don't know if this will ever be null or empty
if (availableResolutions == null || availableResolutions.Count < 1)
return new CameraResolution() { Width = 800, Height = 600 };
//Debugging revealed that the last element in the list
//expresses the highest resolution. This could probably be more thorough.
return availableResolutions[availableResolutions.Count - 1];
}
I compiled using a mac and it worked fine, must be a bug of visual studio on windows.
Everything works perfect on android but when I try to get the profile picture on iOS devices. The image returns null. I checked the Facebook documentation for iOS 9 I have exactly the same plist as shown in documentation. When I run the app in console I see "FB is log in" message but the profile pic has not shown. Can anyone help?
void Awake()
{
instance = this;
FB.Init(SetInıt, OnHideUnity);
}
public void FbLogin()
{
// This is an event trigger when the button pressed.
List<string> permissions = new List<string>();
permissions.Add("public_profile");
FB.LogInWithReadPermissions(permissions, AuthcallBack);
}
void DealWithFbMenus(bool isLoggedIn)
{
// This function is called in SetInit func in Awake.
if(isLoggedIn)
{
fbButton.SetActive(false);
profilePicture.gameObject.SetActive(true);
loggedInPlayer = true;
//FB.API("/me?fields=first_name", HttpMethod.GET, DisplayUserName);
FB.API("/me/picture?type=square&height=128&width=128", HttpMethod.GET, DisplayProfilePic);
}
else
fbButton.SetActive(true);
}
void DisplayProfilePic(IGraphResult result)
{
if(result.Texture != null)
{
profilePicture.sprite = Sprite.Create(result.Texture, new Rect(0,0, 128, 128), new Vector2());
}
}
It is a bug on Unity 5.2. It fixed on new version of Unity 5.3
I have problem in finding the current opened application name.
I used ApplicationManager class for getting the visible applications.
The application descriptors are showing the same name for all these apps Email,Messaging,Sms,call log.
They are displaying "net_rim_bb_messaging_app" for all the above apps.
I need to find a unique identifier/name for these applications(Email,messaging,sms,calllog) when they are opened.
I tried this for the past 3 days and can't find a solution.
Can you please let me know a solution for this?
ApplicationDescriptor [] appDis = manager.getVisibleApplications();
int currentForgroundAppID = manager.getForegroundProcessId();
for(int i=0;i<appIDs.length;i++)
{
if(appDis[i].getModuleName().equals("net_rim_bb_messaging_app"))
{
//print Messaging app in foreground...
}
}
the case with in the for loop above is true for every app in this list.
Email,
Text message
Call log...
But, I need to find a unique way to find the application that was opened.
Thanks In Adv,
Satish.k
following code can display current foregroundApplication name
ApplicationDescriptor[] mAppDes;
ApplicationManager appMan = ApplicationManager.getApplicationManager();
appMan.getForegroundProcessId();
mAppDes = appMan.getVisibleApplications();
for (int i = 0; i < mAppDes.length; i++) {
boolean isFG = appMan.getProcessId(mAppDes[i]) == appMan.getForegroundProcessId();
if(isFG)
{
System.out.println("This is your Foteground application Name"+mAppDes[i].getName());
}else{
System.out.println("This is your Background application Name"+mAppDes[i].getName());
}
}
I want to openOrCreate database in SDcard / Media Card. When i run the application in device (BlackBerry Curve 8900), i find only one root i.e "system/" and running application in simulator (9500), i find three roots as shown in comment in code. I am getting error at;
_db = DatabaseFactory.openOrCreate(_uri);
(error: Method "toString" with signature "()Ljava/lang/String;" is not applicable on this object)
And i am not able to understand what is this error about.
Here is the code.
public void getValues() throws Exception
{
boolean sdCardPresent = false;
String root = null;
Enumeration e = FileSystemRegistry.listRoots();
while (e.hasMoreElements())
{
root = (String)e.nextElement();
System.out.println("Value of root::" +root); // value of root = "system/" when run in device and
// value of root = "store/" "SDCard/" "system/" when run in simulator
if(root.equalsIgnoreCase("system/"))
{
sdCardPresent = true;
}
}
System.out.println("--------------------getValues()----------------------------------");
URI _uri = URI.create(Global.DB_PATH + Global.DB_Main);
System.out.println("Valud of uri::" +_uri);
_db = DatabaseFactory.openOrCreate(_uri); //getting error here.
System.out.println("Valud of _db::" +_db);
_db.close();
I tried these three paths, getting output with "/store"(when run in simulator) but error with rest two paths.Even using "/store" in device is showing the same error.
Global.DB_PATH = "/MediaCard/databases/";
Global.DB_PATH = "/SDCard/databases/";
Global.DB_PATH = "/store/databases/";
Is there any way how to get SDCard/Media Card as root so that i can copy the database in there?
My guess is when you are running your app on a real device you have USB cable plugged in to the device. If this is the case, try to unplug the cable and rerun the app. You may use Dialog.inform() to quickly check what roots you get this time.
private ObjectListField getFileList() {
if (fileList == null) {
fileList = new ObjectListField();
String[] roots = new String[3];
Enumeration enum = FileSystemRegistry.listRoots();
int x = 0;
while (enum.hasMoreElements()) {
if (x < 3) {
roots[x] = enum.nextElement().toString();
}
x++;
}
enum = FileSystemRegistry.listRoots();
fileList.set((roots[2] != null) ? roots : new String[]{"system/", "SDCard/", "store/"});
}
return fileList;
}
Try this code.
I have code that is used to show a device's location. It works just fine on the emulator and it takes me to the fake location at Microsoft. But it didn't work when I build it into the phone, it showed me the world map. Is this a known bug or I have done something wrong? Here is my code:
private GeoCoordinateWatcher loc = null;
private void button1_Click(object sender, RoutedEventArgs e)
{
if (loc == null)
{
loc = new GeoCoordinateWatcher(GeoPositionAccuracy.Default);
loc.StatusChanged += loc_StatusChanged;
}
if (loc.Status == GeoPositionStatus.Disabled)
{
loc.StatusChanged -= loc_StatusChanged;
MessageBox.Show("Location services must be enabled on your phone.");
return;
}
loc.Start();
}
void loc_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
{
if (e.Status == GeoPositionStatus.Ready)
{
Pushpin p = new Pushpin();
p.Template = this.Resources["pinMyLoc"] as ControlTemplate;
p.Location = loc.Position.Location;
mapControl.Items.Add(p);
map1.SetView(loc.Position.Location, 17.0);
loc.Stop();
}
}
}
Instead of using the StatusChanged event, you should use the GeoCoordinateWatcher.PositionChanged event, in from which you should use the GeoPositionChangedEventArgs.Position property, to reflect the changed location.
This is due to my location doesn't support by Bing Map. I couldn't use the Bing Map app installed in my phone neither. Hmm...
