Titanium: Saving file locally from Android's C

I am having issues saving image to local application files in Titanium. Specifically creating file from event.media;

function handleImageEvent(event) {
   imgpreview.image = event.media;

   var imaget = event.media;        
   var f = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory,imagename); 
   f.write(imaget);

}

//imagename :  I am using in the format of 'photo0.png'

Here's the code I have so far that I have tried to put together and test through my own search, they do not work. exception were thrown

[WARN] :   TextView: TextView does not support text selection. Action mode cancelled.

I hope I can provide more details, but I am at lost, apologies Thanks in advance.
