Image uri for wallpaper

Hello everyone!

I'm having trouble developing the wallpaper app
I have a picture with a path like this: /opt/usr/apps/**appid**/res/wgt/home_screen.jpg
That path can not be set as wallpaper
I want to copy it to "/Device storage/Images/"
Can anyone help me?

Thanks everyone!

native or web development? Why cannot you set this as wallpaper?

nathan

Web development, perhaps because the path is private.

see this link and access permissions to app dirs:

Thank Paul L!

I used the solution create image from base64

Would you please share the way you followed? Did you try this way?

You can use filesystem api and the "copyTo"-function

var toDir = "images",
    filename = "home_screen.jpg",
    appLocation = "wgt-package",
    workDir;

function onError(err) {
    alert(err.name);
}

function onSuccess() {
    alert('file copied');
}

function onListing(files) {
    var i = 0;
    
    for(i; i < files.length; i++) {
        if(files[i].name === filename) {
            workDir.copyTo(files[i].fullPath, toDir, false, onSuccess, onError);
        }
    }
}

function onResolve(dir) {
    workDir = dir;
    dir.listFiles(onListing, onError);
}

tizen.filesystem.resolve(appLocation, onResolve, onError, 'rw');

I can not use tizen.filesystem.resolve with appLocation path (/opt/usr/apps/**appid**/res/wgt/)
Maybe i'm wrong?

nathan

I replaced 'rw' to 'r' and succeeded

thanks!
