@zainulhassan Any chance you could include some simple swipe (left right up down) handlers into the extension?

The image can’t open. is there something wrong with my block ?

see the overview here

you might want to load the image from the ASD


Hi Zain,

This is honestly an amazing extension. :grinning: I was hoping to use this in an app I’m trying to make. Part of the app is to save a layout live in the app and then display that layout again to zoom and pinch like this ext provides.

So, I’m using ComponentToImage ext which saves a layout to the ASD (I have verified that image does successfully save there), and then trying to use your extension through the local path, but I’m not getting it right for some reason. I have tried various path possibilities before posting here, including one ASD example given above. I did check out the aia and that works with the URL which is cool. I did test successfully from assets too, just not with the comp’s locally saved image mentioned above.

So after explaining this, I’m asking if you would kindly give advice what possible path to use to do what I explained above :pray:

Here are my blocks currently. Oh, and I did already get permission to WRITE and test an apk not only companion:



I’ve an horizontal_arrangement inside a card_view layout.
so it seems each time I call (clicking on image) ImageViewer1.Create (even previously setting path to: “”)
it open a new Horizontal_arrangement (HA_CV_image_zoom) with image over previous image.

I want to click on an image (inside a cardview) and open the image link in an horizontal arrangement via “imageViewer” taking info for the card view from a list CX_X_Carrello.

Am I missing something?

why does the quality of the image is so much low? can i use this extension with another component? bcz i need HQ quality images in my app thats why

Hello, Thank you, nice extension. :grinning:

One question, Would there be a way to use this extension on Android 10 or higher?
Because, I am testing this extension in Android 9 and 10. In Android 9 works fine, but with Android 10 the image never shows in the arrangement. Even with storage permissions working good in both Android.
I mean, I pick an image from my device, and set the path of the picked image to “path” of the imageViewer ext. but with Android 10 the image doesn’t show. What could I be doing wrong?

I’ve already solved it, using just “image component”: Set Image.Picture > Join: (file://) + file path. No extension :sweat_smile:

anyway thanks

is it working on android 12?

I can see no reason why it should not work…
And if you have an issue, what about providing a screenshot of your relevant blocks?

Hello everyone,
sorry if I reopen the discussion after a long time.
I write because I have an image loading problem with this extension.
I’m attaching a screenshot of the test I’m doing

I have a JPEG image (named “1.jpg”) in the “Pictures” folder of the device’s internal memory
With the blocks I’ve shown, the “1.jpg” image is shown perfectly on Android 9 and 10 but on Android 13 (api31) the screen remains blank (the image is not shown)
I thought the “Pictures” folder was a free folder and shared with all Android versions…
Do we need special permissions to access this folder on Android 13?
I searched for information on the net and I read that the permission must be added to the “AndroidManifest.xml” file: “android.permission.READ_MEDIA_IMAGES”
I tried to make this change but still NOT solved.
Can anyone give me a hint on what to try?
Thanks to anyone who can help me

sorry, I wrote Android 13 (API 31)…actually it’s Android 13 (API 33)


no, currently not
you will need this only after Kodular targets SDK33

what happens if you try this


Thanks Taifun,
(I tested with a simple project as shown in the screenshot and everything works fine on Android 9, 10 and 12…on 13 it shows nothing, blank screen.)
Now I’m at work but in 3 hours I will be able to try your suggestion and report the result.

Nice Extension
:heart: :heart: :heart_eyes:
Is there any option for swiping the image ?
Can we add multiple images?

Hi Taifun,
I tried with the changes you suggested.
On Android 13 it doesn’t work, the page remains completely empty…
I also tried loading Jpegs from the Documents folder and the ASD folder… nothing, always blank screen, no errors shown but it doesn’t display anything.
On android prior to 13 everything works perfectly.
Can anyone do a test on android 13?
I don’t know what to do anymore…
Thank you
