File.exists() Method always returns true even when the file doesn't exist

Im trying to curb duplicate downloads by checking if the file a user is about to download already exists before I proceed to downloading it. Im using the method File.exists() to check for this condition but it seems to be always returning true. Below is my code:

            File destination = new File(Environment.DIRECTORY_DOWNLOADS, "/" + playlistTitle + "/" + image.getImgTitle() + ".jpg");
            if (!destination.exists()) {
                downloadId = downloadImage(image.getImgURL(), image.getImgTitle(), playlistTitle);
                downloadIds.add(downloadId);
            }

If I go directly to that file path before its created, it seems to be empty, but the code above returns true regardless.

new File(Environment.DIRECTORY_DOWNLOADS, "/" + playlistTitle

That can only lead to a path that is not possible.

You should use instead

new File( Environment.getExternalPublicDirectory( 
      Environment.DIRECTORY_DOWNLOADS),......

You can check few things here

first as expected we are getting the permission to read and write the storage media.

and you try also using below method for checking if a file can be read or not

if (!file.canRead()) {
    return false;
}

if two above doesn't work then use this.

if (!file.isFile()) {
     //file doesn't exist    
    }else{
    //file exists
}
