NativeScript when adding custom resource/json files - nativescript

Question

I am creating a project to target Android and in it, I want it to come with a .json file from which some data will be loaded.
I put my .json file into the Android folder. When running "tns run android --device 1" (which is my physical device) I get:
-code-gen:
[mergemanifest] No changes in the AndroidManifest files.
[echo] Handling aidl files...
[aidl] No AIDL files to compile.
[echo] ----------

[aapt] invalid resource directory name: /Users/konrad/Desktop/NativeScript/hello-world/platforms/android/res small.json
BUILD FAILED

Command ant failed with exit code 1
The file is called small.json
EDIT: Even if I remove the file, the problem still remains.

The property of Android is that it restricts access to some parts of the file system. There are two ways of accessing files on NativeScript for Android:
1) JavaScript way
var fs = require('file-system');
var documents = fs.knownFolders.documents();
var myFile = documents.getFile(filename);
as specified in the docs: https://github.com/NativeScript/docs/blob/master/ApiReference/file-system/HOW-TO.md
2) Android specific way including a third party library called "json-simple" which needs to be attached using the command tns library add android .
var context = app.android.context;
var assets = context.getAssets();
var br = new java.io.BufferedReader(new java.io.InputStreamReader(assets.open(filename)));
var parser = new org.json.simple.parser.JSONParser();
try {
parser.parse(br);
} catch (ex) {
var javaEx = ex.nativeException;
var msg = javaEx.getMessage();
console.log("whops! : "+msg);
}
