Where to store .json file in Android Studio project so i could read it with FileReader?

Question

I've created an app on Android Studio with Libgdx that can read a .json file that is stored in the project folder

it goes like this

 private void readFile() {
    JsonParser jsonParser = new JsonParser();
    try (FileReader reader = new FileReader("file.json"))
    {
        //reads file
    } catch (IOException | ParserException e) {
        e.printStackTrace();
    }
}

Everything works on the desktop application, but when I run it on android app ofcourse its not there and it doesn't load. I can't find any information to where it has to be stored. FileReader only lets me input a string, but not the location where the file is.

Is FileReader a bad choice or the location where it is looking can be changed?

You need to store you json file in assets folder. And to read your .json from assets file use below code.

 JSONObject obj = new JSONObject(readJSONFromAsset());

public String readJSONFromAsset() {
String json = null;
try {
    InputStream is = getAssets().open("yourFile.json");
    int size = is.available();
    byte[] buffer = new byte[size];
    is.read(buffer);
    is.close();
    json = new String(buffer, "UTF-8");
} catch (IOException ex) {
    ex.printStackTrace();
    return null;
}
return json;
}
