When I run my application i get JSONException that says No value for temperature. Please help!!
Here is my MainActivity

56,414 PointsIt would help if you could narrow down the method or line that throws the exception. But I'm guessing in getDailyForecast() it's probably the line day.setTemperatureMax(jsonDay.getDouble("temperature")); since the "temperature" field isn't defined for daily forecasts and should be "temperatureMax" instead.
