Android : Universal image loader displaying different image

I'm using universal image loader in my Android app and it's doing something weird.

I have users and each one of them can have different image profile, what I noticed is that when user 1 replaces his image, the UIL seems to load the old one, when I do this,

imageLoader.displayImage("file://" + profileImgFile, imgview);

it displays some old image, but when I do this

myBitmap = BitmapFactory.decodeFile(profileImgFile.getAbsolutePath(), options);
imgview.setImageBitmap(myBitmap);

it displays the new one,

My UIL setting is below,

DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
        .cacheOnDisc().imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
        .bitmapConfig(Bitmap.Config.RGB_565).cacheOnDisk(true).cacheInMemory(true).build();
ImageLoaderConfiguration.Builder builder = new ImageLoaderConfiguration.Builder( context).defaultDisplayImageOptions(defaultOptions).memoryCache(
        new WeakMemoryCache());

ImageLoaderConfiguration config = builder.build();
 ImageLoader.getInstance().init(config);

What am I doing wrong?
