Web and WebWorks Development

[_MARIO_]

Hi,

I was wondering how to write files from a WebWorks app to the SD card or internal storage. Looking at the API there seems to be something that enables me to write to SD:

var filePath = "file:///SDCard/BlackBerry/Sample.txt";

var blob_data = blackberry.utils.documentToBlob(testData);

blackberry.io.file.saveFile(filePath, blob_data);

I also added the following to config.xml:

file:///SDCard/BlackBerry

Any idea why it isn't working?

By the way, what is a blob???

Regards

Did you figure this out yet?

Which OS version are you trying these calls?

BlackBerry 5.0, 6.0 or PlayBook?

BlackBerry 6.0 does not support the documentToBlob() function

I'm looking to do WebWorks for OS 6.0 and Playbook.  I just heard that at least for Playbook the feature will be available in mid-June.

Yes, file I/O will be coming to WebWorks on PlayBook in a week or two.  However, documentToBlob and blobToDocument are only supported on BB5

Ok, so I was trying to access a file in the Playbook simulator but it didn't work.  The simulator is 1.0.1 and the SDK is the version released just a week or two ago. 

The code is below:

var filePath = blackberry.io.dir.appDirs.app.storage.path + "/favorites.txt";
	function onFileOpen(fullPath, blobData){
	      globalBlob = blobData;
	      alert(globalBlob);
	}
	alert(filePath);
	if (blackberry.io.file.exists(filePath)) {
	    try{
			blackberry.io.file.readFile(filePath,onFileOpen, true);
		}catch(e){
	      alert(e);
		}
	}
	else {
		var globalBlob = "TEST";
		blackberry.io.file.saveFile(filePath, globalBlob);
	}

Looks like I found my answer:

This feature isn't supported yet!
