NLTK not working in Buildozer Android KivyMD app

[Tanish Gupta]

I am making a basic app with KivyMD, which uses NLTK. The program works well in Pycharm IDE, but while compiling with Buildozer, the Android App crashes after opening up. JSON works well importing the json file dataset; so, I suppose..NLTK has some issues. 

Can also refer to: python - NLTK not working in Android Buildozer App with KivyMD - Stack Overflow

This is the main.py file:

import kivymd 

from kivymd.app import MDApp 

from kivymd.uix.screen import Screen

from kivymd.uix.label import MDLabel 

import nltk 

import json 

with open("intents.json") as file: 

    data = json.load(file) 

words = str(nltk.word_tokenize(str([data["intents"][0]["patterns"][0]]))) 

from nltk.stem.lancaster import LancasterStemmer
stemmer = LancasterStemmer() 

stemmertest = stemmer.stem('addition') 

class MainApp(MDApp): 

     def build(self): 

         screen = Screen() 

          label = MDLabel(text=words, pos_hint={'center_x': 0.7, 'center_y': 0.3}) 

         label2 = MDLabel(text=stemmertest, pos_hint={'center_x': 0.7, 'center_y': 0.5})

         screen.add_widget(label) 

         screen.add_widget(label2) 

         return screen 

MainApp().run()

I am writing the requirements in the Buildozer.spec as:

requirements = python3,kivy==2.0.0,kivymd==0.104.1,nltk==3.2.5,goslate,chardet,idna

Please help me in this.
