copy file to "document" folder

[Matteo De vita]

Good morning, I'm writing an app to create a gcode file from an image captured by the camera. My problem is copying the output file to the "document" folder. Could you please tell me how to copy a file from the app's internal folder to the Android "document" folder? I'm using Motorola Android 14. Thanks

HI,

See app.GetSpecialFolder

Images would normally go to "Pictures"

(but you can try "Documents")

You probably need to write to a subfolder

For Android 10+ you probably have scoped storage 

and may need to look at CheckPermission and GetPermission

Regards, ah

Good morning,
I tried this simple one, but it doesn't work. Any suggestions?

function OnStart()

{

    var check = app.CheckPermission( "Camera,ExtSDcard,Network,Storage" );

    alert(check)

          if( check )

    {

        app.GetPermission( check, PermissionResult );

    }

    else alert( "everything ok!" ); 

     fidr =app.GetSpecialFolder("Pictures")

             alert(fidr)

          app.WriteFile(fidr+"/file.txt")

          alert(app.FileExists(fidr+"/file.txt"))

   

}

 

function PermissionResult( ungranted )

{

    alert( "ungranted: " + ungranted );

}

You can try this example, but remember that it only allows Documents folder (maybe DCIM and Pictures folder too).

const workingFolder = "/Internal/Documents/MyData";

function OnStart() {

lay = app.CreateLayout("Linear", "VCenter,FillXY");

txt = app.AddText(lay, "The file was not read");

// Check if the necessary permissions are granted.

if (checkPerm()) {

read();

write();

} else {

// If permissions are not granted, request them.

requestPerm();

}

app.AddLayout(lay);

}

// Check if the required permissions are granted.

function checkPerm() {

return !!app.CheckPermission(workingFolder);

}

// Request permissions from the user.

function requestPerm() {

// Show a popup to inform the user that permission is required.

app.ShowPopup("Allow access to the Documents folder.", "Permission required");

// Request permission to access the internal storage.

app.GetPermission("internal", OnPermission);

}

// Handle the result of the permission request.

function OnPermission(path) {

// If permission is not granted, show an alert.

if (!path) {

app.Alert("Permission not granted!");

} else if (!checkPerm()) {

// If the permission is granted but the folder is not selected, alert the user.

alert("Make sure to select the Documents folder.");

requestPerm(); // Request permission again.

} else {

// If permissions are granted and folder is selected, proceed to write and read.

write();

read();

}

}

function write() {

// Create content with the current date and time.

const content = "Last visit: " + new Date().toLocaleString();

// Ensure the working folder exists.

app.MakeFolder(workingFolder);

// Write the content to a file named "test.txt" in the working folder.

app.WriteFile(workingFolder + "/test.txt", content);

}

function read() {

// Read the content of the file "test.txt".

const content = app.ReadFile(workingFolder + "/test.txt");

txt.SetText(content);

}

Hi, Thanks for the suggestion.

I tried... it gives me 2 errors.

App.checkPermission(/internal/documents/myData) WARNING: App.checkPermission() failed!(Starage access is a Premium feature!)

App.GetPermission(internal,OnPermission)   WARNING:   App.GetPermission() failed!(Starage access is a Premium feature!) At this point, to copy files outside the app folder to "document" or "image," is it necessary to upgrade to the premium version?

[Alan Hendry]

HI,

Hmm

Check and Get Permissions don't show as Premium in the docs 

Here's my code to test writing to different folders

It should tell you if the folder exists, and say Works! if it can write there

(Android 15 I can only write to documents and its subfolders)

_AddPermissions("Storage")
_AddPermissions("extsdcard")

HI,

I seem to recall that if you aren't Premium

then Get and Check Permissions 

are restricted to "extsdcard"

[Alan Hendry]

HI,

Also see the SAF example

Touch top-right icon, then rocket, search for storage (tick general).
