Android java.io.FileNotFoundException image open failed: ENOENT from internal storage

Hello I am working with android . I want to save multiple captured images in a folder(programmatically created in internal storage of the device) and read this file from the folder and send to server as multipart form. I used the below code for attaching images to multipart ,

for(int i=0;i<Captured_imagePath.size();i++) {
   try {
      final File file2 = new File(android.os.Environment.getExternalStorageDirectory() + "/MyFolder/" + Captured_imagePath.get(i));

      final FileBody fileBody = new FileBody(file2);
      entityBuilder.addPart(file2.getName(), fileBody);
      entityBuilder.setBoundary(boundary);
   } catch (Exception e) {
      Log.i(TAG, "Except:: " + e.toString());
   }
}

When I use only one image in this loop it works fine. When more than one images, it cause the following exception

 8594-9144/? W/System.err﹕ java.io.FileNotFoundException: /storage/sdcard0/MyFolder/ 20160123_121858.jpg: open failed: ENOENT (No such file or directory)

I added permissions in the manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

my complete multpart uploading method is

   public String uploadMultipart(String url,String json ,ArrayList<String> imagePath,ArrayList<String> Captured_imagePath) {
        String result="";
        File  file=null;
        String boundary = "-------------" + System.currentTimeMillis();



        try
        {
            HttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(url);

            MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
            entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

            entityBuilder.addTextBody("json", json);
            entityBuilder.setBoundary(boundary);
            if(imagePath.size()!=0)
            {
                file = new File(android.os.Environment.getExternalStorageDirectory() + "/MyFolder/" + imagePath.get(0));

                entityBuilder.addBinaryBody(file.getName(), file,  ContentType.create("image/jpeg"), imagePath.get(0));

                entityBuilder.setBoundary(boundary);
            }

            if(Captured_imagePath.size()!=0)
            {

                for(int i=0;i<Captured_imagePath.size();i++)
                {

                    try {


                        final File file2 = new File(android.os.Environment.getExternalStorageDirectory() + "/MyFolder/" + Captured_imagePath.get(i));



                        final FileBody fileBody = new FileBody(file2);
                        entityBuilder.addPart(file2.getName(), fileBody);
                        entityBuilder.setBoundary(boundary);

                    }catch (Exception e)
                    {
                        Log.i(TAG, "Except:: " + e.toString());
                    }

                }


            }


            HttpEntity entity = entityBuilder.build();
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            entity.writeTo(bytes);
            String content = bytes.toString();

        //    Log.i(TAG,"sending data"+content);
          //  writeToFile("shanu",content);

            post.setEntity(entity);
            HttpResponse response = client.execute(post);
            HttpEntity httpEntity = response.getEntity();
            result = EntityUtils.toString(httpEntity);
            Log.i(TAG2, result);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return result.toString();

I had searched for this file in my folder manually and it exist in the same folder.Then why I got this file not found exception ? How can I resolve this issue? please help.

You have an extra white space in your path.

Try with this

file = new File(android.os.Environment.getExternalStorageDirectory() + "/MyFolder/" + imagePath.get(0).toString().trim());
