Android copy/Load image using file object

[db251]

I am able to successfully copy and load a image using the file object in windows using:

FileSelReturn$( "File" ) Apppath$ + "PictureCopy.jpg"

I want to place a copy of a file in a folder easily accessible to the user on android. I would like to keep my existing code using the file object, it says the file object is compatible with android.


FileSelReturn$( "File" ) ExternalStorageDirectory$( "Android object" ) + "M/PictureCopy.jpg"

does not work.

I don't see the folder "m" in external storage?

How do I create a folder? or is there something else I am missing?

[db251]

Using the file object
create directory
ExternalStorageDirectory$( "Android object" ) + "m"
does not work.

is not working because your path is incorrect

ExternalStorageDirectory$( "Android object" ) + "/" + "M/PictureCopy.jpg"

but for these you need write external storage , something that you can't use above 10, and read external storage

[db251]

I am using:

Build:31
Minimum:5.1
Target: 10

To understand, are you saying that when implementing this and compatibility:

Running Android 11, I will be unable to write to external storage, but a device running 10 and down can?

or

Running Android 11, but using target android 10 that this will be backwards compatible with android 11 devices and still work?

Also to verify:

data storage directory: hidden and inaccessible to user, though allows copy, delete, read and write to it

temp directory: not permanent storage

external storage directory: make a local folder found on device storage (not sd card) /storage/emulated/0 that allows read,write, copy, delete - also accessible to user, not hidden

Public storage: I am unsure how this works or is located? Can I make a folder here that allows read,write,copy,delete, and is accessible to user?

secondary storage: requires a sd card, folder that can use read,write,copy, delete, accessible to user, not hidden

[Fernando]

yes please read about scopestorage https://developer.android.com/about/...rivacy/storage

and here https://developer.android.com/training/data-storage

data storage directory: hidden and inaccessible to user, though allows copy, delete, read and write to it --- YES

temp directory: not permanent storage --- YES & NO, in some cases could stay until device user requires more space

external storage directory: make a local folder found on device storage (not sd card) /storage/emulated/0 that allows read,write, copy, delete - also accessible to user, not hidden --- NOT ANYMORE only to version 9

Public storage: I am unsure how this works or is located? Can I make a folder here that allows read,write,copy,delete, and is accessible to user? NO, WHAT ARE PUBLIC IS PUBLICSCOPESTORAGE

secondary storage: requires a sd card, folder that can use read,write,copy, delete, accessible to user, not hidden REQUIRES STORAGE MANAGE PERMISSION https://developer.android.com/training/data-storage/manage-all-files

Thank you for your response. I read the links you sent.
I am confused about clickteams implementation of reading and writing to device storage.

------------------------------------------------------------------------------------------------------
In my use case:
CREATE user accessible folder
data storage/file.jpg COPY TO user accessible folder/file.jpg
user accessible folder/file.jpg COPY TO data storage/file.jpg
DELETE user accessible folder/file.jpg
WRITE .txt to user accessible folder/file.txt

As seen, read,write,copy,delete need to be ALLOWED between (data storage) and (user accessible folder)
------------------------------------------------------------------------------------------------------

Where do I create User accessible folder?

What permissions do I select in the .mfa android properties to allow:
read,write,copy,delete data storage
read, write, copy, delete user accessible folder

I do not see "manage storage permission" in the android mfa properties.

[Fernando]

publicscopestorage create the same external public folder but for application use, whihc btw doesn't need any permission only set read_external_storage

[db251]

To confirm using location publicscopestorage
I can:
copy user files elsewhere to publicscopestorage, and in public scope storage Write folder,copy-delete-file, AND this folder is accessible in file manager by the user?

What do I put in this context to create a folder, with m being the folder?

PublicStorageDirectory$( "Android object", >Type Name (Pictures, Movies, Documents, DCIM, Downloads, Music, etc.)< ) + "/" + "m"


What do I put in this context to access a file?

PublicStorageDirectory$( "Android object", >Type Name (Pictures, Movies, Documents, DCIM, Downloads, Music, etc.)< ) + "/" + "m/file.jpg"

[db251]

I am having difficulty understanding, thank you for your patience and time.


To make a new folder, I use the file object, directory actions, create a directory?

Where is publicscopestorage folder located on android storage?

Where is datastorage located on android storage?

When making a folder and manipulating files with publicscopestorage, will this do the same actions with locations in android 11 as on a device running android 10?
In effect, implementing publicscopestorage will be backwards compatible for file locations in 10 and down?

I have spent time looking for these answers in clickteam forum/online and testing how to do it myself before asking you and can't seem to figure it out.

THANK YOU
