Why doesn't loading an image from a file work?

Question

Android

Here is the code:

Bitmap result = BitmapFactory.decodeFile("/data/data/com.lizaalert/cache/14350.jpg");
if(result == null){
Log.e(MainActivity.TAG, "onPostExecute::BitmapFactory Bitmap result == null" );
}
ImageView iv = (ImageView) findViewById(R.id.imageView1);
iv.setImageBitmap(result);

which is registered in the OnCreate activity, just for checking.
and although the file exists but BitmapFactory.decodeFile returns null.
What could be the problem?
In general, the task is the following: download the image file by url and save it to the local cache. Actually, this file is the cached image...
There are no exceptions...
Some kind of devilry :)
Maybe BitmapFactory works exclusively with bitmap (bmp) ?
