BlackBerry - Volume saving issue - blackberry

I am facing problem to store volume level on persistence memory. I am using following code:
int _currentVolume = 50;
Code for setting player volume level:
volumeControl = (VolumeControl) _player.getControl("VolumeControl");
volumeControl.setLevel(_currentVolume);
setVolume(_currentVolume);
Code for storing volume:
public void Save() {
StoreInfo info = new StoreInfo();
info.setElement(StoreInfo.VOL2, String.valueOf(volumeControl.getLevel()));
_data.addElement(info);
synchronized (store) {
store.setContents(_data);
store.commit();
}
}
public void Get() {
synchronized (store) {
_data = (Vector) store.getContents();
if (!_data.isEmpty()) {
StoreInfo info = (StoreInfo) _data.lastElement();
}
}
}
But the code is not working :(. Need some help on this issue.

I don't see where you apply Integer.parseInt((String)StoreInfo.getElement(StoreInfo.VOL2)) to your _currentVolume.

App always crashes when it comes through SplashScreen and it works fine if started from MainActivity.
MvvmCross does not guarantee that App start is run on the UI thread. I will most likely run on a ThreadPool Thread.
In order to marshal a piece of code to the main thread, you can resolve the IMvxMainThreadAsyncDispatcher (>= 6.1.x) or IMvxMainThreadDispatcher and request an Action to run on the main thread:
var dispatcher = Mvx.Resolve<IMvxMainThreadAsyncDispatcher>();
int count;
await dispatcher.ExecuteOnMainThreadAsync(() =>
{
count = _realm.All<IsFirstTimeAppStartUpRealm>().Count();
});
I have a reasonably nice way of removing these code smells from my applications. I've just recently started using Realm (liking it so far), but I have always used ReactiveProperty to notify my view layer of VM changes - and it's really nice.
https://github.com/runceel/ReactiveProperty
ReactiveProperty is a Rx framework for .NET, which wraps your properties in an instance that produces your INotifyPropertyChanged events as needed. You chain all these properties together as they depend on each other, and events propagate throughout them. You no longer have these long lists of "notify of this, notify of that" after a property change.
Instead you declare how all your members inter-depend, in a single section of your code (typically your constructor)
As a result, you can place the root of the chain on the Realm thread, and all dependent notifications are published on that thread.
So, my ViewModels look something like this (pseudocode):
class VM
{
public ReactiveProperty<AppStartInfo> Entity { get; set; }
public ReactiveProperty<bool> IsFirstLaunch { get; set; }
public VM(){
var syncCtx = SynchronizationContext.Current;
Entity = new ReactiveProperty<AppStartInfo>();
// this property will fire its notifications on the syncCtx.
// remember to bind your view to "IsFirstLaunch.Value"
IsFirstLaunch = Entity.SubscribeOn(syncCtx).Select(x => x.IsFirstLaunch).ToReactiveProperty()
}
public async Task Init()
{
// let's get our realm instance on to the syncCtx.
syncCtx.Post(() => {
Entity.Value = Realm.Find(typeof(AppStartInfo), 0); // or whatever you need.
});
}
}

Memory issue when using CGImage.ScreenImage in a loop using Mono Touch

I'm trying to create an app to read QR codes using Monotouch and C# port of Zxing but I'm hitting memory issues. While the app processes captured screen frames the app receives memory warnings and is then shut down. I have removed the call to Zxing to track down where the memory issue stems from and can reproduce the issue with just capturing the screen image in a loop.
Here is the code:
using System;
using System.Drawing;
using System.Collections.Generic;
using System.Threading;
using MonoTouch.UIKit;
using MonoTouch.Foundation;
using MonoTouch.CoreGraphics;
using com.google.zxing;
using com.google.zxing.common;
using System.Collections;
using MonoTouch.AudioToolbox;
using iOS_Client.Utilities;
namespace iOS_Client.Controllers
{
public class CameraOverLayView : UIView
{
private Thread _thread;
private CameraViewController _parentViewController;
private Hashtable hints;
private static com.google.zxing.MultiFormatReader _multiFormatReader = null;
private static RectangleF picFrame = new RectangleF(0, 146, 320, 157);
private static UIImage _theScreenImage = null;
public CameraOverLayView(CameraViewController parentController) : base()
{
Initialize();
_parentViewController = parentController;
}
private void Initialize()
{
}
private bool Worker()
{
Result resultb = null;
if(DeviceHardware.Version == DeviceHardware.HardwareVersion.iPhone4
|| DeviceHardware.Version == DeviceHardware.HardwareVersion.iPhone4S)
{
picFrame = new RectangleF(0, 146*2, 320*2, 157*2);
}
if(hints==null)
{
var list = new ArrayList();
list.Add (com.google.zxing.BarcodeFormat.QR_CODE);
hints = new Hashtable();
hints.Add(com.google.zxing.DecodeHintType.POSSIBLE_FORMATS, list);
hints.Add (com.google.zxing.DecodeHintType.TRY_HARDER, true);
}
if(_multiFormatReader == null)
{
_multiFormatReader = new com.google.zxing.MultiFormatReader();
}
using (var screenImage = CGImage.ScreenImage.WithImageInRect(picFrame))
{
using (_theScreenImage = UIImage.FromImage(screenImage))
{
Bitmap srcbitmap = new System.Drawing.Bitmap(_theScreenImage);
LuminanceSource source = null;
BinaryBitmap bitmap = null;
try {
source = new RGBLuminanceSource(srcbitmap, screenImage.Width, screenImage.Height);
bitmap = new BinaryBitmap(new HybridBinarizer(source));
try {
_multiFormatReader.Hints = hints;
resultb = null;
//_multiFormatReader.decodeWithState(bitmap);
if(resultb != null && resultb.Text!=null)
{
InvokeOnMainThread( () => _parentViewController.BarCodeScanned(resultb));
}
}
catch (ReaderException re)
{
//continue;
}
} catch (Exception ex) {
Console.WriteLine(ex.Message);
}
finally {
if(bitmap!=null)
bitmap = null;
if(source!=null)
source = null;
if(srcbitmap!=null)
{
srcbitmap.Dispose();
srcbitmap = null;
}
}
}
}
return resultb != null;
}
public void StartWorker()
{
if(_thread==null)
{
_thread = new Thread(()=> {
bool result = false;
while (result == false)
{
result = Worker();
Thread.Sleep (67);
}
});
}
_thread.Start();
}
public void StopWorker()
{
if(_thread!=null)
{
_thread.Abort();
_thread = null;
}
//Just in case
_multiFormatReader = null;
hints = null;
}
protected override void Dispose(bool disposing)
{
StopWorker();
base.Dispose(disposing);
}
}
}
Interestingly I took a look at http://blog.reinforce-lab.com/2010/02/monotouchvideocapturinghowto.html to try and see how others were capturing and processing video and this code suffers from the same as mine, quitting after about 40 seconds with memory warnings.
Hopefully the QR codes will be scanned in less than 40 seconds but I'm not sure if the memory ever gets released so the problem may crop up after many codes have been scanned. Either way it should be possible to capture a video feed continuously without memory issues right?
This is somewhat counter-intuitive, but the ScreenImage property will create a new CGImage instance every time you call it, so you must call Dispose on that object as well:
using (var img = CGImage.ScreenImage) {
using (var screenImage = img.WithImageInRect(picFrame))
{
}
}
I will just add the actual solution that worked for me which combined information from previous answers. The code inside the loop looks like:
using (var pool = new NSAutoreleasePool ())
{
using (var img = CGImage.ScreenImage)
{
using (var screenImage = img.WithImageInRect(picFrame))
{
using (_theScreenImage = UIImage.FromImage(screenImage))
{
}
}
}
}
GC.Collect();
The original System.Drawing.Bitmap from zxing.MonoTouch suffered from a lack of Dispose which made it never release the unmanaged memory it allocated.
The more recent one (from your link) does free the unmanaged memory when Dispose is called (it's better). However it creates a bitmap context (in it's constructor) and does not dispose it manually (e.g. with a using). So it relies on the garbage collector (GC) to do it later...
In many cases this is not a big issue since the GC will, eventually, free this context instance and will reclaim the associated memory. However if you're doing this in a loop it's possible you'll run out of (unmanaged) memory before the GC kicks in. That will get you memory warnings and iOS can decide to kill your application (or it could crash by itself).
but I'm not sure if the memory ever gets released
Yes, it should be - but maybe not as fast as you need the memory back. Implementing (and using) IDisposable correctly will solve this.
Either way it should be possible to capture a video feed continuously without memory issues right?
Yes. Make sure you're releasing your memory as soon as possible, e.g. with using (var ...) { }, and ensure the 3rd party code you use does the same.

storing data in persistence store

I am facing an issue in storing data in persistence store,i am trying to store events for different dates in persistence store but the data is getting overridden the code is :
public ListEventScreen(Vector v,String timezone) {
for(int i=0;i<v.size();i++){
EventBean bean=(EventBean)v.elementAt(i);
//a normal label in the app, just to display text, anchored left
LabelField label = new LabelField(bean.getSummary(),LabelField.FIELD_LEFT);
//add the label to the screen
add(label);
saveUserInfo(v);
}
}
public void saveUserInfo(Vector vectorData){
// static{
store = PersistentStore.getPersistentObject( 0x1dfc10ec9447eb14L );
synchronized(store) {
store.setContents(vectorData);
store.commit();
}
//}
}
Please let me know what has to be changed.
Every time you call store.setContents(), the current contents of the persistentStore are overwritten with the Vector you are passing in. You need to make sure you are loading the previous events that were already in the persistentStore into your Vector before then adding new events into that Vector that you are then saving.
You are also calling saveUserInfo() on every iteration of your loop in ListEventScreen(). You should be calling it outside of the loop instead.
I would do something like this:
public ListEventScreen(Vector v,String timezone) {
Enumeration e = v.elements();;
while (e.hasMoreElements()){
EventBean bean = (EventBean) e.nextElement();
//a normal label in the app, just to display text, anchored left
LabelField label = new LabelField(bean.getSummary(),LabelField.FIELD_LEFT);
//add the label to the screen
add(label);
}
}
public void loadUserInfo(Vector vectorData){
// static{
store = PersistentStore.getPersistentObject( 0x1dfc10ec9447eb14L );
synchronized(store) {
Vector v = (Vector) store.getContents();
Enumeration e = v.elements();
while (e.hasMoreElemens){
vectorData.add(e.nextElement());
}
}
//}
}
public void saveUserInfo(Vector vectorData){
// static{
store = PersistentStore.getPersistentObject( 0x1dfc10ec9447eb14L );
synchronized(store) {
store.setContents(vectorData);
store.commit();
}
//}
}
.
{
Vector v = new Vector();
loadUserInfo(v);
ListEventScreen(v, ...);
... modify v contents as needed ...
saveUserInfo(v);
}
If you do not mind changing the format of your persistent store contents, I would wrap the store in a singleton class instead:
public class EventBeans extends Vector implements Persistable
{
private static final long persistKey = 0x1dfc10ec9447eb14L;
private static EventBeans _instance = null;
private static PersistentObject _persist = null;
static{
_persist = PersistentStore.getPersistentObject(persistKey);
_instance = (EventBeans) _persist.getContents();
if (_instance == null){
_instance = new EventBeans();
_persist.setContents(_instance);
_persist.commit();
}
}
private EventBeans(){
super();
}
public static EventBeans getInstance(){
return _instance;
}
public static synchronized void save(){
_persist.commit();
}
}
.
{
Vector v = EventBeans.getInstance();
ListEventScreen(v, ...);
... modify v contents as needed ...
EventBeans.save();
}

Saving the photo to a class

I would like to save the PhotoResult from the cameraCaptureTask into my class which I'm using as a collection and then saving into Isolated Storage:
void cameraCaptureTask_Completed(object sender, PhotoResult e)
This is part of an ObservableCollection. I want to save the photo into this collection.
[DataMember]
public Image VehicleImage
{
get
{
return _vehicleImage;
}
set
{
if (value != _vehicleImage)
{
_vehicleImage = value;
NotifyPropertyChanged("VehicleImage");
}
}
}
I'm using the example from: http://www.blog.ingenuitynow.net and in the example it works fine, but it is setting up an individual Isolated Storage and I would just like to join to my existing collection.
I'm thinking that I can't use the Image type. What would be the best way to accomplish what I'm hoping to do?
Just to answer the comment below. This is what the .Save is doing:
public static void Save<T>(string name, T objectToSave)
{
using (IsolatedStorageFile storageFile = IsolatedStorageFile.GetUserStoreForApplication())
using (IsolatedStorageFileStream storageFileStream = new IsolatedStorageFileStream(name, System.IO.FileMode.Create, storageFile))
{
DataContractSerializer serializer = new DataContractSerializer(typeof(T));
serializer.WriteObject(storageFileStream, objectToSave);
}
}
I think I finally figured out your issue. In your ObservableCollection I personally would not keep an image in there. Instead I would keep a BitmapSource to use less resources, however you may have reasoning why your doing that.
My Process
Convert the Image.Source(BitmapSource) to a byte[]
Save the byte[] to storage
Load the byte[] from storage
Convert the byte[] to and a Image.Source(BitmapSource)
Save Generic To Isolated Storage (In my utility class: IsolatedStorage_Utility.cs)
public static void Save<T>(string fileName, T item)
{
using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(fileName, FileMode.Create, storage))
{
DataContractSerializer serializer = new DataContractSerializer(typeof(T));
serializer.WriteObject(fileStream, item);
}
}
}
Load Generic To Isolated Storage (In my utility class: IsolatedStorage_Utility.cs)
public static T Load<T>(string fileName)
{
using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(fileName, FileMode.Open, storage))
{
DataContractSerializer serializer = new DataContractSerializer(typeof(T));
return (T)serializer.ReadObject(fileStream);
}
}
}
Convert BitmapSource to byte[] (In my utility class: Image_Utility.cs)
public static byte[] ImageToByteArray(BitmapSource bitmapSource)
{
using (MemoryStream stream = new MemoryStream())
{
WriteableBitmap writableBitmap = new WriteableBitmap(bitmapSource);
Extensions.SaveJpeg(writableBitmap, stream, bitmapSource.PixelWidth, bitmapSource.PixelHeight, 0, 100);
return stream.ToArray();
}
}
Convert byte[] to BitmapSource (In my utility class: Image_Utility.cs)
public static BitmapSource ByteArrayToImage(byte[] bytes)
{
BitmapImage bitmapImage = null;
using (MemoryStream stream = new MemoryStream(bytes, 0, bytes.Length))
{
bitmapImage = new BitmapImage();
bitmapImage.SetSource(stream);
}
return bitmapImage;
}
Example
private void TestImageConversion(object sender, RoutedEventArgs e)
{
byte[] image1AsByteArray = Image_Utility.ImageToByteArray((BitmapSource)Image1.Source);
IsolatedStorage_Utility.Save<byte[]>("Image1.jpg", image1AsByteArray);
BitmapSource image1AsBitmapImage = Image_Utility.ByteArrayToImage(IsolatedStorage_Utility.Load<byte[]>("Image1.jpg"));
Image2.Source = image1AsBitmapImage;
}
Keep in mind this is a jpg saving. If you want to save a png thn you need to use a library of CodePlex or create your own PNGEncoder.
I hope this helps!
Actually in that blog, he knows the ImageFileName stored recently so he is able to retreive the same image from the Isolated storage. i dont think so that example helps you according to your comment.
But If you want store the Picture along with the object means you have to serialize whole object along with the picture taken.
serializing the picture is achieved by converting stream you got to byte[] array and you can convert from byte[] array to BitmapImage again.)
Image conversion and serialization is expalianed here in this link
use this sample and you can serialize with whole object.
In this example I'm excepting that you got ObservableCollection where you want to store all of the images lets say it's name is VehicleImages.
So at the cameraCaptureTask_Completed you load all of the data from IsolatedStorage to VehicleImages and now you add the new VehicleImage to VehicleImages and save it to IsolatedStorage.
Code for save and load:
public static void Save<T>(string name, T objectToSave)
{
using (IsolatedStorageFile storageFile = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream storageFileStream = new IsolatedStorageFileStream(name, System.IO.FileMode.Create, storageFile))
{
DataContractSerializer serializer = new DataContractSerializer(typeof(T));
serializer.WriteObject(storageFileStream, objectToSave);
}
}
}
public ObservableCollection<T> Read<T>(string name)
{
using (IsolatedStorageFile storageFile = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream storageFileStream = new IsolatedStorageFileStream(name, System.IO.FileMode.Open, storageFile))
{
DataContractSerializer serializer = new DataContractSerializer(typeof(T));
return (ObservableCollection<T>)serializer.ReadObject(storageFileStream);
}
}
}

Backup/Restore net.rim.device.api.util.Persitable object with DesktopManger

The task is to backup/restore Persistable object with BB Desktop Manager or in any other way. The main aim is to keep data between device firmware updates...
I have:
public final class UserList implements Persistable {
//The persistable objects.
private Hashtable fData;
//Initialize the class with empty values.
public UserList() {
fData = new Hashtable();
}
//Initialize the class with the specified values.
public UserList(Hashtable p) {
fData = p;
}
public Hashtable getData() {
return fData;
}}
I also have implemented SyncItem (as found in one of the examples)
public final class UserListSync extends SyncItem {
private static UserList fList;
private static final int FIELDTAG_NAME = 1;
private static final int FIELDTAG_AGE = 2;
private static PersistentObject store;
static {
store = PersistentStore.getPersistentObject(0x3167239af4aa40fL);
}
public UserListSync() {
}
public String getSyncName() {
return "Sync Item Sample";
}
public String getSyncName(Locale locale) {
return null;
}
public int getSyncVersion() {
return 1;
}
public boolean getSyncData(DataBuffer db, int version) {
boolean retVal = true;
synchronized (store) {
if (store.getContents() != null) {
fList = (UserList)store.getContents();
}
}
try {
Enumeration e = fList.getData().keys();
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = (String) fList.getData().get(key);
//Write the name.
db.writeShort(key.length() + 1);
db.writeByte(FIELDTAG_NAME);
db.write(key.getBytes());
db.writeByte(0);
//Write the age.
db.writeShort(value.length() + 1);
db.writeByte(FIELDTAG_AGE);
db.write(value.getBytes());
db.writeByte(0);
}
} catch (Exception e) {
retVal = false;
}
return retVal;
}
//Interprets and stores the data sent from the Desktop Manager.
public boolean setSyncData(DataBuffer db, int version) {
int length;
Hashtable table = new Hashtable();
Vector keys = new Vector();
Vector values = new Vector();
boolean retVal = true;
try {
//Read until the end of the Databuffer.
while (db.available() > 0) {
//Read the length of the data.
length = db.readShort();
//Set the byte array to the length of the data.
byte[] bytes = new byte[length];
//Determine the type of data to be read (name or age).
switch (db.readByte()) {
case FIELDTAG_NAME:
db.readFully(bytes);
keys.addElement(new String(bytes).trim());
break;
case FIELDTAG_AGE:
db.readFully(bytes);
values.addElement(new String(bytes).trim());
break;
}
}
} catch (Exception e) {
retVal = false;
}
for (int i = 0; i < keys.size(); i++) {
table.put(keys.elementAt(i), values.elementAt(i));
}
try {
//Store the new data in the persistent store object.
fList = new UserList(table);
store.setContents(fList);
store.commit();
} catch (Exception e) {
retVal = false;
}
return retVal;
}}
The entry poing is following:
public class SyncItemSample extends UiApplication {
private static PersistentObject store;
private static UserList userList;
static {
store = PersistentStore.getPersistentObject(0x3167239af4aa40fL);
}
public static void main(String[] args) {
SyncItemSample app = new SyncItemSample();
app.enterEventDispatcher();
}
public SyncItemSample() {
UserListScreen userListScreen;
//Check to see if the store exists on the BlackBerry.
synchronized (store) {
if (store.getContents() == null) {
//Store does not exist, create it with default values
userList = new UserList();
store.setContents(userList);
store.commit();
} else {
//Store exists, retrieve data from store.
userList = (UserList)store.getContents();
}
}
//Create and push the UserListScreen.
userListScreen = new UserListScreen(userList);
pushScreen(userListScreen);
}}
And here is an implementation of screen:
public final class UserListScreen extends MainScreen {
Vector fLabels = new Vector();
Vector fValues = new Vector();
VerticalFieldManager leftColumn = new VerticalFieldManager();
VerticalFieldManager rightColumn = new VerticalFieldManager();
UserList fList;
public UserListScreen(UserList list) {
super();
fList = list;
//Create a horizontal field manager to hold the two vertical field
//managers to display the names and ages in two columns.
VerticalFieldManager inputManager = new VerticalFieldManager();
HorizontalFieldManager backGround = new HorizontalFieldManager();
//Array of fields to display the names and ages.
LabelField title = new LabelField("User List",
LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
setTitle(title);
final TextField fld1 = new TextField(TextField.NO_NEWLINE);
fld1.setLabel("input label");
inputManager.add(fld1);
final TextField fld2 = new TextField(TextField.NO_NEWLINE);
fld2.setLabel("input value");
inputManager.add(fld2);
final ButtonField fld3 = new ButtonField();
fld3.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
fList.getData().put(fld1.getText().trim(), fld2.getText().trim());
refresh();
}
});
fld3.setLabel("add");
inputManager.add(fld3);
add(inputManager);
//Add the column titles and a blank field to create a space.
LabelField leftTitle = new LabelField("label ");
leftColumn.add(leftTitle);
LabelField rightTitle = new LabelField("value");
rightColumn.add(rightTitle);
refresh();
//Add the two vertical columns to the horizontal field manager.
backGround.add(leftColumn);
backGround.add(rightColumn);
//Add the horizontal field manager to the screen.
add(backGround);
}
private void refresh() {
leftColumn.deleteAll();
rightColumn.deleteAll();
fLabels.removeAllElements();
fValues.removeAllElements();
//Populate and add the name and age fields.
Enumeration e = fList.getData().keys();
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = (String) fList.getData().get(key);
final LabelField tmp1 = new LabelField(key);
final LabelField tmp2 = new LabelField(value);
leftColumn.add(tmp1);
rightColumn.add(tmp2);
fLabels.addElement(tmp1);
fValues.addElement(tmp2);
}
}
public boolean onClose() {
System.exit(0);
return true;
}}
So as you see it should be very easy...
So all of these I run application, add values to Persistent object and they are added correctly, are stored during device resets and so on...
When I run Desktop Manager and make a Backup it seems that UserList is backed-up, as size of backup grows together with adding new data into persistent store.
But when I run "Wipe device" on my BB 9300 (and all data from Persistent store is cleared as it is expected) and then run Restore from just made backup file - nothing is updated in the Application and persistent store is seems to be empty.
In some examples I have found adding alternate entry point "init" but I can't tune eveything like it is described with my EclipsePlugin
Could you advice me how to store data in backup file and the to retrieve the same data from backup and load it back to the application, or how to log any of events with Desktop Manager?
If someone has experienced the same problem you can try to disconnect the device before wiping it. It is strange but it helped :)
