Android: open failed: ENOENT (No such file or directory)

Hi i am trying to read excel from assets and wanted to convert it into JSON, But i am getting the error: open failed:ENOENT(No such file or directory), searched many SO questions but could not find the solution Below is my code

public void readXlsFileAndConvertToJsonObject() {
     JSONArray jsonArray = new JSONArray();
     JSONArray mainJsonArray = new JSONArray();
     try {

         File file = new File("file:///android_asset/filters.xls");
         FileInputStream fis = new FileInputStream(file);
         //final FileInputStream file = new FileInputStream(new File("filters.xls"));

         int count = 0;
         // Get the workbook instance for XLS file
         HSSFWorkbook workbook = new HSSFWorkbook(fis);

         // Get first sheet from the workbook
         HSSFSheet sheet = workbook.getSheetAt(0);

         // Iterate through each rows from first sheet
         Iterator < Row > rowIterator = sheet.iterator();
         while (rowIterator.hasNext()) {
             Row row = rowIterator.next();
             //LOGGER.info("count is " + count);
             if (count == 0 || count == 1) {} else {
                 try {
                     JSONObject jsonMaterialObject = new JSONObject();
                     // Name
                     jsonMaterialObject.put("name", row.getCell(0)
                         .toString());
                     // thick ness
                     jsonMaterialObject.put("thickness", row.getCell(4)
                         .toString());
                     // rating_1
                     jsonMaterialObject.put("rating_1", row.getCell(5)
                         .toString());
                     // rating_2
                     jsonMaterialObject.put("rating_2", row.getCell(6)
                         .toString());

                     jsonMaterialObject.put("low_frequency_rank", row
                         .getCell(7).toString());

                     jsonMaterialObject.put("medium_frequency_rank", row
                         .getCell(8).toString());

                     jsonMaterialObject.put("high_frequency_rank", row
                         .getCell(9).toString());

                     // Add file size
                     final File dir = new File("file:///android_asset/filename");
                     final File[] ListFiles = dir.listFiles();
                     boolean found = false;
                     if (ListFiles.length == 0) {} else {
                         for (File aFile: ListFiles) {
                             System.out.println("Afile Name " + aFile.getName());
                             System.out.println("A file from json  Name " + row.getCell(0).toString());
                             if (aFile.getName().equalsIgnoreCase(
                                     row.getCell(0).toString() + ".pdf")) {
                                 jsonMaterialObject.put("fileSize", truncateDecimal(aFile.length() / 1024, 2));
                                 found = true;
                             }
                             if (found) {
                                 break;
                             }
                         }

                         jsonMaterialObject.put("pdfFileName", row
                             .getCell(0).toString() + ".pdf");
                     }

                     jsonArray.put(jsonMaterialObject);
                 } catch (JSONException e) {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }
             }
             count++;

         }
         ((Closeable) file).close();

     } catch (FileNotFoundException e) {} catch (IOException e) {}
     createMaterialJson(jsonArray.toString(), "finalfile.json");
 }

I mentioned the permissions as below

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

Below is my Trace

11-25 12:32:35.535: I/System.out(20019): Exception accured in readXlsFileAndConvertToJsonObject /file:/android_asset/filters.xls: open failed: ENOENT (No such file or directory)

People also ask

How do you fix open failed Enoent No such file or directory?

The ENOENT (No such file or directory) error may occur in application, If the application do not have storage permission. We suggest you to ensure whether the application has storage permission to read and write file in storage location. We have modified sample to provide storage permission at run time.

What is Enoent?

It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.

This issue wasted my hours of time :P

Thoroughly check your file names by Logging.

This issue is comes with some file names with digits.

I solved this by changing the file name.
