how to delete a photo that is in Internal Storage.

let me suggest you to store the image in ASD rather than in the root directory of the emulated sdcard
from there is should be easy to delete again…
also make sure to use the correct path… file:///storage/emulated/0/...

Ok but how to store the image in ASD with the Image Editor component ? I’ve tried a lot of times to save on a different directory but each time it doesn’t work.

[Taifun]

Use the correct path… my file extension offers a method for that…

Path of root is /storage/emulated/0/

[ForRob]

Still doesn’t work when i use /storage/emulated/0/[global file_name]

Can you share your app here

[ForRob]

Sure this is tha aia file :
tiktik(2).aia (129.5 KB)

Also, I have another problem with some devices that downloads the app, they can’t accept the WRITE_STORAGE and READ_STORAGE permission (they can’t accept from the app settings menu and when I use the block “ask for permission”)

@ForRob

WRITE_STORAGE and READ_STORAGE permission

yes, these permissions never existed and WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE do not exist anymore for devices Android 11+

A small correction: WRITE_EXTERNAL_STORAGE does no longer exist on Android 11+ and READ_EXTERNAL_STORAGE does no longer exist on Android 13+.

Path of root is /storage/emulated/0

The File component uses a relative path.

@ForRob

This is the file I want to delete:

You cannot delete a file in the root dir of the external storage on Android 11+ (without all-file-permission, which is not allowed by Google in the Play Store).

Ok so how to store the edited pictures on a specific folder and then delete it ?

@bodymindpower

WRITE_EXTERNAL_STORAGE does no longer exist on Android 11+ and READ_EXTERNAL_STORAGE does no longer exist on Android 13+.

Ok but why is there an error The permission WRITE_EXTERNAL_STORAGE is denied on some devices when I just want to pick an image with the"Image_Picker" component.

@ForRob

Image_Picker

Some this explanation

Image Picker: Error 908: permission READ_MEDIA_IMAGES has been denied

Probably nothing. The ImagePicker tries to request READ_EXTERNAL_STORAGE on Android 13+ with the compiled app (APK). With Companion, correctly READ_MEDIA_IMAGES is requested, but this is not declared in the Companion APK either. Back to APK: Since READ_EXTERNAL_STORAGE no longer exists on Android 13+, an error message is of course displayed: “The permission READ_… has been denied. Please…”. I therefore used the ActivityStarter (android.intent.action.PICK), which I generally prefer to the Ima…

In the same thread you can find a workaround

So as I’ve read in this topic :

@Taifun

Some basics on Android storage system

I’ve tried to store the picture in the ASD using this path :

 /storage/emulated/0/Android/data/<packageName>/files/

But it still doesn’t work and the Image Editor is not returning any image

[Taifun]

@ForRob

I’ve tried to store the picture in the ASD using this path :

 /storage/emulated/0/Android/data/<packageName>/files/

Very good
Now if you use the ApplicationSpecificDirectory method from the tools extension, you get that path dynamically, which will work for the companion app and after building any app

[ForRob]

Do I have to do this ? I don’t understand

It stillk doesn’t work

[Taifun]

Now use Do it to check the filename…

Most probably a slash is missing…

use Do it to debug your blocks, see also tip 4 here App Inventor: How to Learn | Pura Vida Apps

see also Live Development, Testing and Debugging

[ForRob]

So this is what I get :

I added a slash and this is what I get :

On the companion when I try to set the vertical arrangement image to the edited image it doesn’t show anything :

And in the Internal Storage the image is not here anymore (btw I don’t now how to find the image and i don’t know if it’s findable)

Sorry for the delay I wasn’t home for 4 days
