the test.xml file is in the files folder, which is in the app folder
when calling the method below, 1 2 3 is displayed in the log, after which an error occurs: File not found: /data/user/0/com.example.myapplication/files/test.xml: open failed: ENOENT (No such file or directory)
method :
protected Document buildDoc(Context context, String fileName) throws Exception{
Document doc = null;

try {
File file = new File(context.getFilesDir(), "test.xml");
Log.d("tag", "1");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
Log.d("tag", "2");
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Log.d("tag", "3");

doc = dBuilder.parse(file);
Log.d("tag", "4");

} catch (FileNotFoundException e) {
Log.e("error", "File not found: " + e.getMessage());
throw e;
} catch (Exception e) {
throw e;
}
return doc;
}

I just can’t understand why and how to fix the error

I cleared the cache and rebooted the studio, but the error does not go away
