[RSS Reader] app hangs when refreshing Shorts view

[Lisette Slegers]

I am subscribed to 15 feeds. In the Shorts view, when I press refresh, the refresh process continues for more than 10 minutes. Refreshing a topic with less feeds only takes a short time.

---
Desired solution

Refreshing should take no longer than 30 seconds.

---
Question

How can we optimise the process so that the user doesn't have to wait too long? For example, if a topic or the Shorts view contains more than a certain number of feeds, could we speed up the process by only taking a few articles of each feed, and show older articles in a more gradual way when the user scrolls further to the right?

Actually I know what happened in your situation, because we r not using the regular "listview" which provides dynamic memory management, all articles will load into memory, when this process start, the app "hang".

I have few solution to solve this, will start fixing this bug after another bug research (drag & drop and swipe-remove)

Not sure if this is what you meant, but the same thing happens for me in list view?

when refresh begins, the busy indicator starts spinning, here's the process:
1. download current topic's articles, busy indicator looks normal;
2. download finished, start loading those articles into memory, the busy indicator "stop", whole app hangs in this step;

And pls count that how long does the busy indicator stops, which means the app takes how much time to load into memory

For optimal memory management we also need dynamic Tabs management :)
I hope we will get it soon!
