Avoid freezing.

Question

Hi,

I have below code in my which allow the user Like ❤️ a Post just like Instagram likes for example

The problem is when I use Button Click or TapGesture with async like this:

async void LikeTapGestureRecognizer_Tapped(object sender, EventArgs e)

and if the user tried to like 3-4 post randomly in a short time then because if the async it will freeze for secodns everytime he Tap until the code is successfull.

How an I avoid this and let the code run at the background thread just like Instgarm, twitter and others..

Here is the code:

var client = new HttpClient();

client.BaseAddress = new Uri("https://www.domain.com/submit_like.php");

var content = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("post", "1"),
    new KeyValuePair<string, string>("user", SecureStorage.GetAsync("UserID").Result ),
});

var response = await client.PostAsync("https://www.domain.com/submit_like.php", content);

Thanks,
Jassim

Answer 1

Is there a reason you're using SecureStorage.GetAsync("UserID").Result instead of just await SecureStorage.GetAsync("UserID")?

The former will block the UI thread & prevent messages from being pumped in the event loop.
