Question

I am trying to use GSON to convert a Json string to an object. When I load the string from a file like this:

File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "jsonTest");
    BufferedReader br = new BufferedReader(new FileReader(f));
    String Json = br.readLine();
    br.close();
    Gson gson = new Gson();
    dreFieldArray = gson.fromJson(Json, DreField[].class);

It works fine. However, if I try to use a string resource instead like this:

String Json = this.getString(R.string.NewFileData);
Gson gson = new Gson();
    dreFieldArray = gson.fromJson(Json, DreField[].class);

I get an EOFexception. The string in resources was copied from the file, so it should be identical. I read that this exception can occur if there are extra characters after the object, but I don’t see any. Any ideas on what is going wrong here?

Answer 1

getString() will not display all special characters. You might have to escape them.

Log the content of R.string.NewFileData, see the missing characters and then escape them in the strings.xml (put a “\” in front of the removed characters)
