Nope, you are storing the path to the image on your device.

[D_M]

Thank you TIMAI2, but I have not the images on my device because I deleted them.
If I save a path, and the images are not on my phone, I shouldn't see them... is it right?
Please I need to understand

@D_M

But my app runs correctly

On your device
Now test it on another device to display the stored image

Could you kindly give me the right blocks combination to use for my application?

The first post of this thread links to this example
What about adjusting these blocks to your needs?

Save image, sound, clip (video), canvas in TinyDB. Extension Base 64. Download file from the web and convert it to string

In this old topic I put an example to take an image with the Cam, convert it to a Base 64 string, save that string in a TinyDB. Read the content of the string from the TinyDB, convert it to a file and display it in an image component.

What about point n 7 here?

7.- Blocks: ImageToBase64, Base64ToImage, CanvasToBase64 and TakePictureToBase64. These blocks were ideas from @TIMAI2 : Convert an Image component to string Base 64.

[TIMAI2]

What about it ?

[D_M]

Do you think following solution is ok?

[TIMAI2]

Have you tested your blocks ? Do they work as intended?

If not, what does happen, what errors do you get?

[D_M]

Hi @TIMAI2, my blocks seems work, also in another phone.
But I would like to be sure (do you remember, before my app also worked, but I saved only link to images, not images ).
I ask this, because in other examples I see blocks with a path text... I have to use it?

[TIMAI2]

Because you are using ImageToBase64 you do not need a path.

[D_M]

Thank you very much @TIMAI2!!!

Hi im trying to use this extension to take an image from the user's photo gallery and convert it to base64 so that gemini can analyze it. I believe something is wrong with the conversion because the app never analyzes the image. is this the correct block to use for this process?

No need to post in two places, we will stay with your request in the other topic:

The KIO4_Base641.CanvasToBase64 cases an error with the .apk saying Runtime Error buildCache Why is this happening?

[Taifun]

@Superman_Son

Runtime Error buildCache

Probably it is a size issue of the canvas? How large is it? Which device and Android version are you using for your tests? Did you try another device?

To find out more about the runtime error use logcat

Capturing Device Logs using adb logcat

ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. In this post, we’ll discuss how to install and use ADB. Installation: ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE . EDIT: …

How do you Convert Signature to Base64 with KIO4 CanvasToBase64 – Firebase Error Help?

Hi, I have a question. I'm using Juan's KIO_BASE641 extension and I was thinking of adding a signature. I mean, I'd sign it on a canvas and then convert it to Base64 to add it to a Firebase dictionary. But when I try to do it with his "CanvasToBase64" component and my SignatureImage, I get the following error: "com.google.appinventor.components.runtime.Canvas$CanvasView.buildCache Note: You will not see another error reported for 5 seconds." Could someone help me or give me some advice, pleas…
