it helps some times ColinE is right with all his informations. I only want to add my subclass of ObservableCollection that I use for this specific case.
code :
public class SmartCollection<T> : ObservableCollection<T> {
    public SmartCollection()
        : base() {

    public SmartCollection(IEnumerable<T> collection)
        : base(collection) {

    public SmartCollection(List<T> list)
        : base(list) {

    public void AddRange(IEnumerable<T> range) {
        foreach (var item in range) {

        this.OnPropertyChanged(new PropertyChangedEventArgs("Count"));
        this.OnPropertyChanged(new PropertyChangedEventArgs("Item[]"));
        this.OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));

    public void Reset(IEnumerable<T> range) {

Best way to avoid Toast accumulation in Android

I think the issue was by ths following , You can use the cancel() method of Toast to close a showing Toast.
Use a variable to keep a reference to every Toast as you show it, and simply call cancel() before showing another one.
code :
private Toast mToast = null; // <-- keep this in your Activity or even in a custom Application class

//... show one Toast
if (mToast != null) mToast.cancel();
mToast = Toast.makeText(context, text, duration);

//... show another Toast
if (mToast != null) mToast.cancel();
mToast = Toast.makeText(context, text, duration);

// and so on.
public class SingleToast {

    private static Toast mToast;

    public static void show(Context context, String text, int duration) {
        if (mToast != null) mToast.cancel();
        mToast = Toast.makeText(context, text, duration);
SingleToast.show(this, "Hello World", Toast.LENGTH_LONG);

it should still fix some issue I'm making my first iOS game using SpriteKit, and I'm applying an impulse for my sprite each time I tap on the screen, something like this: , you can try:
code :
 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

    CGVector vecVelocity = _ball.physicsBody.velocity;

    if(vecVelocity.dx == 0 && vecVelocity.sx == 0) {

        [_ball.physicsBody applyImpulse:CGVectorMake(0, 5)];

this will help Here are three alternatives to consider:
Option 1: Just pick a type and return it
code :
virtual std::vector<TEdge> FindShortestPath(size_t source, size_t dest, TGraph& graph) = 0;
virtual void TraverseShortestPath(
 size_t source,
 size_t dest,
 TGraph& graph,
 std::function<void(TEdge*)> callback) = 0;
template <class TGraph, class OutIt>
void FindShortestPath(size_t source, size_t dest, TGraph& graph, OutIt output)
  // details...
