Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {

String json = null;

try {

InputStream is = context.getAssets().open("file_name.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;

}

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see

Hope you will get what you want.
