Dynamic Cardview: App Crashing

[Future_Applications (Learning)]

It’s crashing even if 32 Items

As I said without seeing anyblocks we can not tell what might cause the problem. See for example… airtable as database 1200 rows, 5 columns … no crash

Tested with 1200 rows, 5 colums works very fast, took 6-7 seconds to load database

[Future_Applications (Learning)]

Can I see your blocks?

[Still-learning (1-2-3-4...)]

@Future_Applications

your blocks?

if possible have a look at it

[F/OS] Recycler List View - Render larger data sets efficiently using `RecyclerView` for AppInventor & Distros

See now, blocks are almost reduced into simple one… especially creating labels and setting text on each label was did with just single procedure. Based on this design labels will auto generate according to the col size… RecyclerList1(1).aia (309.5 KB) Update: I have used a new of way creating labels based on gsheet col count. You no need to mention how many to create by number. [image] Also setting in text also simplified too much with this extension like this [image] just test …

I mean is how to get the airtable data using this Recycler List View

[dora_paz (Dora)]

Get all rows. Response is in json, use web component and dictionary blocks to get columns

No way of hanging with airtable, runs as much as smoother… I just tested with 500 data’s, loads created view in less than 5 sec , upon refresh created view even more less than previous value Just see this Fantastic effect of Recycler View And my blocks [blocks(1)] Blocks used Related to spreadsheet is, [image] [image]

I don’t understand, do you mind teaching it to me?

[Future_Applications (Learning)]

I looked up for the blocks and I don’t understand it no matter how hard I try

[Future_Applications (Learning)]

It keeps crashing if the data is more than 50, this is my blocks

[Future_Applications (Learning)]

Forgot to show the block, When the Screen Initialized, I call Spreadsheet 1. Get Column, Column Name: Title, and Max Record: 1200

@dora_paz

Get all rows. Response is in json, use web component and dictionary blocks to get columns

How am I able to get larger items in 3 seperated Columns “Title”, “ID”, and “Date”? because if I will use the common method, it lags and crashes the app

[dora_paz (Dora)]

Try this way, create another global variable for example thumbnails to create and empty list. Before creating list view with images for each item in list global id, add items to global thumbnails using call get thumbnail from videoID where videoId is get item. Once that list is created then create List View with Image and get images from global thumbnails

[Future_Applications (Learning)]

Ill try this one

[Future_Applications (Learning)]

@dora_paz

for each item in list global id, add items to global thumbnails using call get thumbnail from videoID where videoId is get item

Is this Correct?

---

[dora_paz (Dora)]

No try this way

[dora_paz (Dora)]

After that create List View with Image using global thumbnails

[Future_Applications (Learning)]

is this correct?

[Future_Applications (Learning)]

it gives an error

"Select list item: List index too large"
Select list item: Attempt to get item number 1 of a list of length 0:[]

[dora_paz (Dora)]

Your list is empty, did you get data from airtable ?

[dora_paz (Dora)]

Use Do it on all global lists to see if they are empty or not
