Question

I want to programmatically access a specific file which will be included in my project folder. Is there a way to do this? If so, where in my project folder do I put the file, and what is some simple code to get its file path?

private void saveFileToDrive() {
        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    java.io.File spreadsheet = new java.io.File("Untitled spreadsheet.xlsx");
                    String filePath = spreadsheet.getAbsolutePath();
                    System.out.println("file path is"+filePath);

                    URL fileURL = getClass().getClassLoader().getResource("Untitled spreadsheet.xlsx");
                    String filePath2 = fileURL.getPath();
                    System.out.println("file path2 is"+filePath2);

                    java.io.File fileContent = new java.io.File(filePath);
                    FileContent mediaContent = new FileContent("application/vnd.ms-excel", fileContent);

                    File body = new File();
                    body.setTitle(fileContent.getName());
                    body.setMimeType("application/vnd.ms-excel");


                    File file = service.files().insert(body, mediaContent).setConvert(true).execute();

                    if (file != null) {
                        showToast("File uploaded: " + file.getTitle());
                    }
                    else
                             ;
                } catch (UserRecoverableAuthIOException e) {

                    startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
                } catch (IOException e) {

                    e.printStackTrace();
                }
            }
        });
        t.start();
    }

Put the file in root folder of your project. Then get the File URL, Path and other details as:

   File file = new File("test.txt");
   String filePath = file.getAbsolutePath();

EDIT: Alternate way (if the file is in your classpath e.g. put the file in “src” folder, and make sure its moved in “bin” or “classes” folder after compilation):

  URL fileURL = getClass().getClassLoader().getResource(fileName);
  String fileName = fileURL.getFile();
  String filePath = fileURL.getPath();
