Might be helpful to explain to developers what and where the "cache" is, and why, how and when this is extension would be useful for them to use in their projects?

Yes, you can store data that in not used for the lifetime of the app, like instead of loading image from web again you could cache it, and next time if it exists we can load it, else the error FileNotFound occurs, so then you need to load it again from web.

Also, you could do temporary actions on file, instead of doing them in the non-cache storage.

4

Is it something like a clipboard? Or is it more of a memory range where the app's temporary variables are stored?

5

Clipboard?? :thinking:

Condition depends.

Does the programmer know what the clipboard and copying to the clipboard are?
Maybe I'll ask otherwise. Can the data that has been copied to the cache be used outside the application?

7

I think no. It can be used within the application.

Another useful extension, different from the others. :+1:

component_set_get (8)

Returns the file type data of the value 2

component_set_get (9)

Returns the text type data of the value 1

I don't see any mention of a value 1 or value 2 in your description of the extension.

Please explain.

thank you for your contribution
did you also test the extension here in MIT App Inventor?

As you know, currently there are a few differences between Kodular and MIT App Inventor... MIT App Inventor already supports AndroidX libraries and some new annotations and does not support the old support libraires anymore...

Hello Kumaraswamy

Looks like your extension could speed-up file handling. Where you say:

How can a developer quantify "large"? I think we need a means of verifying the space available.

12

Is it not dependent on android functions and its "smart" skills to delete unnecessary data? Is it predictable?

13

The format of the data saved event.


Yes I do, first I test here and also in Kodular.


Like there is no limit, like when the user deletes the cache memory using the app or anything, it will be deleted. Or may the system do the thing.

I dont know...

Can any one help me for saving the images into catche so that I can load it faster for next

Any Example please.. for storing web images into catche.

i want to store the value of a text input, so that when you close the application and reopen it, it is already saved.
But when i try to code it in my app it doesn't work.

The first time i open the app, the cache is empty so how can i detect that error?

17

What about using TinyDB to store your data? There also is a valueIfTagNotThere option...

Cache is flammable. The user can go to the Cleaner app on their device or in Settings and delete all cache, and your data will be lost. Cache is good for files that are stored temporary and can be recreated easily.

If you do not want the user to permanently delete your data, look for alternatives.
