rssreader | Simple google reader clone in Flask and Backbone.js | User Interface library

You are enqueuing by a unique name but looking it up by a (non-existent) tag. Use https://developer.android.com/reference/androidx/work/WorkManager#getWorkInfosForUniqueWork(java.lang.String) instead.

Here are a few pointers:

• Make a class where you store the information from RSS for each element (eg. MyPodcastEntry.cs with properties Index (count), Subject, Summary, ...)
• Populate those classes in your rssRead and add them to a List
• Add that list to the listbox instead of using Tuple<>
• Override ToString in that class to adjust how they are displayed in the listbox

This will help you keep and use the information from RSS. There is no need to run rssRead every time you click the listbox. Once you have read the RSS feed and put the data into your class then you can access this information any time.

Now in your MouseClick event handler you can access the SelectedItem of the listbox, cast it to your class, and then access the properties that you previously assigned, to assign to the richtextbox text, no need for either rssRead or the loop.

Optional stuff:

• instead of MouseClick event, use SelectedIndexChanged
• There are a bunch of rss feed reader nugets available, no need to make your own nvm you're using Syndication which is fine :)
• Clean code
  • Unused variables x, y
  • Define variables subject and summary in the foreach instead of at the top
  • Better yet, don't use subject and summary variables at all since their values are already stored in item.Title.Text and item.Summary.Text

Have fun with C#!

Why do four requests? You can take the items from a single request and display random 4. But in order for Random to work it needs to be outside the for loop.

You need to pass the command as a reference without the () when binding to .

You can do so by either defining a separate function:

As we found out, getActivity() returns null. It means in that moment fragment is not attached to some Activity. May be your call happens before attaching or after detaching - I think after detach because synchronous code doesn't throw exception.

Anyway there is Fragment lifecycle error. If this information is not enough I need more code of your fragment class.

Oops

Didn't see it at first time :)

You are right, you need Asynctask. But it is too much to explain here, it has already been explained very thoroughly here, so you might wanna take a look:

What you need to make sure is to run your network calls in doInBackground, you can manipulate the UI in onPreExcute and after finish in onpostExecute. For more details please visit the link.

if RSS.php lives in the root directory, that code will only work on the homepage and not on secondary pages. you can add a forward slash so your about page isn't looking for /about/RSS.php

NSUserDefault support these classes :NSNumber（Integer、Float、Double），NSString，NSDate，NSArray，NSDictionary，BOOL;

FeedInfo is a custom class , and you cannot put it in the NSUserDefault;

You should turn the FeedInfo object to NSData , then add it;

The sendRequest() function must happen in the background (aka doinbackground in the asynctask)

All because you need to make network calls on back thread,

Having said that you can use Volley or Retrofit Libraries instead for easier network calls
