This is becouse I don't have all cities from all countries and when json is empty for city app crash. YOU CAN UPDATE JSON FILE WITH CITY THAT YOU NEED

thank you sir,

https://we.tl/t-JM9bJHgxDF Download this zip file from link. Unpack it and open in Android Studio There is app, and picker Library In picker library in asset folder you have two JSON files cities.json and states.json they are connected by state_id, so for your state id enter new city in city.json and picker will work. also you can add state for country_id that is missing , you have CountryPicker.java class in java classes of picker library, here you can also add new country that is missing , with flag, country_id ......... Hope you understand what you have to do and later you can use this in your project where you need it
