Strange behaviour on Tizen 4.0

My application was rejected by TizenStore because it doesnt runs perfect on Tizen 4.0 and I dont know why.

I download images from Server A and write them to the storage on the phone. It works perfectly on Tizen 2.3, Tizen 2.4 and Tizen 3.0. But something goes wrong in Tizen 4.0

My write to storage looks like this

var file = dir.createFile(data.name + ".png");
	
	if(file !== null) {
		file.openStream(
			'w', 
			function(stream) {	
				stream.writeBase64(data.image);
				stream.close();
				callback(data.state);
			},
			function(err) {
				console.log("Error " + err.message);
			},
			"UTF-8"
		);
	}

To show the image I use this

var file;

    if(this.name === 'Recruit') {
		return '/images/recruit.png';
	} else {
		file = dir.resolve(this.cleanName() + ".png");
		
		return file.toURI();		
	}

Result in Tizen 2.x and Tizen 3.x

Result in Tizen 4.0

Currently I use "wgt-private" as location, but got the same issue with different locations like "downloads", "images".

Hi Marco,
I found similar problem once, I use scanFile function to update contents. After calling scanFile the image/file showed correctly!

Privilege: http://tizen.org/privilege/content.write

Code:

/* Following example scans "tizen.jpg" in media directory */

function errorCB(err)
{
  console.log("The following error occurred: " + err.name);
}

function successCB(path)
{
  console.log("scanning is completed");
}

tizen.filesystem.resolve("images/tizen.jpg", function(imageFile)
{
  tizen.content.scanFile(imageFile.toURI(), successCB, errorCB);
});
