Weird "java.io.FileNotFoundException:" error

In my video recording code, to implement pause functionality, 'n' no. of mp4 files are created in sequence.
(file1.mp4, file2.mp4, file3.mp4.....)

Following code is used for file name sequence; (thanks to Robpuk38):
http://androidforums.com/threads/writing-filename-in-sequence.985745/

After this, these 'n' no of files are parsed using mp4Parser:

Code (Text):

1.  
2. public class MergeVide extends AsyncTask<String, Integer, String> {
3.         File files;
4.  
5.         @Override
6.         protected void onPreExecute() {
7.          
8.  
9.             files = new File("/storage/emulated/0//Videos/Temp/");
10.             File[] list = files.listFiles();
11.             for (File aList : list) {
12.                 System.out.println(aList + " piece of video");
13.             }
14.  
15.  
16.  
17.         }
18.  
19.      
20.  
21.         @Override
22.         protected String doInBackground(String... params) {
23.  
24.             String[] videoUris = new String[]{
25.  
26.                     Arrays.toString(files.listFiles()),
27.  
28.             };
29.  
30.      
31.             try {
32.                 List<Movie> inMovies = new ArrayList<Movie>();
33.                 for (String videoUri : videoUris) {
34.                     inMovies.add(MovieCreator.build(videoUri));
35.                 }
36.                 List<Track> videoTracks = new LinkedList<Track>();
37.                 List<Track> audioTracks = new LinkedList<Track>();
38.                 for (Movie m : inMovies) {
39.                     for (Track t : m.getTracks()) {
40.                         if (t.getHandler().equals("soun")) {
41.                             audioTracks.add(t);
42.                         }
43.                         if (t.getHandler().equals("vide")) {
44.                             videoTracks.add(t);
45.                         }
46.                     }
47.                 }
48.                 Movie result = new Movie();
49.                 if (audioTracks.size() > 0) {
50.                     result.addTrack(new AppendTrack(audioTracks.toArray(new Track[audioTracks.size()])));
51.                 }
52.                 if (videoTracks.size() > 0) {
53.                     result.addTrack(new AppendTrack(videoTracks.toArray(new Track[videoTracks.size()])));
54.                 }
55.                 Container out = new DefaultMp4Builder().build(result);
56.                 FileChannel fc = new RandomAccessFile(String.format("/storage/emulated/0//output.mp4"), "rw").getChannel();
57.                 out.writeContainer(fc);
58.                 fc.close();
59.             } catch (FileNotFoundException e) {
60.                 e.printStackTrace();
61.             } catch (IOException e) {
62.                 e.printStackTrace();
63.             }
64.  
65.  
66.  
67.             File oldFile = new File("/storage/emulated/0//Videos/output.mp4");
68.             mFileName = new File("/storage/emulated/0//Videos/ video.mp4");
69.             boolean success = oldFile .renameTo(mFileName );
70.  
71.             if(success)
72.                 System.out.println("file is renamed..");
73.             return String.valueOf(mFileName);
74.         }

All the recorded 'n' of file.mp4 are listed in the console, but I also get "java.io.FileNotFoundException:" for the same files!

CONSOLE:

/com.exapps.videorec I/System.out﹕ /storage/emulated/0/Videos/Temp/file1.mp4 piece of video
/com.exapps.videorec I/System.out﹕ /storage/emulated/0/Videos/Temp/file2.mp4 piece of video
/com.exapps.videorec I/System.out﹕ /storage/emulated/0/Videos/Temp/file3.mp4 piece of video
/com.exapps.videorec W/System.err﹕ java.io.FileNotFoundException: [/storage/emulated/0/Videos/Temp/file1.mp4, /storage/emulated/0/Videos/Temp/file2.mp4, /storage/emulated/0/Videos/Temp/file3.mp4]: open failed: ENOENT (No such file or directory)

.................

But if i set the above code as:

Code (Text):

1.  
2. String[] videoUris = new String[]{
3.  
4.         /storage/emulated/0/Videos/Temp/file1.mp4,
5.         /storage/emulated/0/Videos/Temp/file2.mp4,
6.         /storage/emulated/0/Videos/Temp/file3.mp4
7.  
8. };

It does work perfectly..

Any help appreciated..!

 

Thanks..
The slashes aren't the issue, i have tried using a single one... the result is the same ... I'll give a try to LV426's solution,..!

 

I am using Android Studio..

It gives an error: foreach cannot be applied to type 'java.io.File'
