Question

When I try to check the existence of a particular file, I get java.lang.illegalArgumentException: File contains a path separator

What is the right way to do this using getFileStreamPath(..)?

File file = getActivity().getFileStreamPath("mnt/sdcard/photo/1342147146535.jpg");
   if(file.exists()){
     Toast.makeText(getActivity(), "File exists in /mnt", Toast.LENGTH_SHORT);
}

I also tried the following to replace the first line of the above codes. None of these worked.

File file = getActivity().getFileStreamPath("file:///mnt/sdcard/photo/aviary_1342147146535.jpg");
            File file = getActivity().getFileStreamPath("/mnt/sdcard/photo/1342147146535.jpg");
//          File file = getActivity().getFileStreamPath("mnt/sdcard/photo/1342147146535.jpg");
//          File file = getActivity().getFileStreamPath("file:///mnt/sdcard/photo/1342147146535.jpg");

            if(file.exists()){
            Toast.makeText(getActivity(), "File exists in /mnt", Toast.LENGTH_SHORT);}
            else {
                Toast.makeText(getActivity(), "File NOT exists in /mnt", Toast.LENGTH_SHORT);}
