I'm new to developing and I'm trying to develop an android weather application for an assignment I followed this tutorial on youtube to create it everything works fine but I couldn't get the data from the "weather" object on the below API.
OpenWeatherMap API
{
"coord": {
"lon": -122.08,
"lat": 37.39
},
"weather": [
{
"id": 800,
"main": "Clear",
"description": "clear sky",
"icon": "01d"
}
],
"base": "stations",
"main": {
"temp": 282.55,
"feels_like": 281.86,
"temp_min": 280.37,
"temp_max": 284.26,
"pressure": 1023,
"humidity": 100
},
"visibility": 16093,
"wind": {
"speed": 1.5,
"deg": 350
},
"clouds": {
"all": 1
},
"dt": 1560350645,
"sys": {
"type": 1,
"id": 5122,
"message": 0.0139,

},
"timezone": -25200,
"id": 420006353,
"name": "Mountain View",
"cod": 200
}
