I am having almost the same issue as the one posted here https://teamtreehouse.com/forum/fatal-exception-main
I did not find a suitable answer for my issue on that thread and rather than add to the extensive list of others' issues Ive decided to create this thread.
Now, my issue is coming down to the forecast.getIconId method. Specifically the line beginning the if statement is the one being flagged. Any help would be appreciated.
public static int getIconId(String iconString) {
// clear-day, clear-night, rain, snow, sleet, wind, fog, cloudy, partly-cloudy-day, or partly-cloudy-night.
int iconId = R.drawable.clear_day;
if (iconString.equals("clear-day")) {
iconId = R.drawable.clear_day;
}
else if (iconString.equals("clear-night")) {
iconId = R.drawable.clear_night;
}
else if (iconString.equals("rain")) {
iconId = R.drawable.rain;
}
else if (iconString.equals("snow")) {
iconId = R.drawable.snow;
}
else if (iconString.equals("sleet")) {
iconId = R.drawable.sleet;
}
else if (iconString.equals("wind")) {
iconId = R.drawable.wind;
}
else if (iconString.equals("fog")) {
iconId = R.drawable.fog;
}
else if (iconString.equals("cloudy")) {
iconId = R.drawable.cloudy;
}
else if (iconString.equals("partly-cloudy-day")) {
iconId = R.drawable.partly_cloudy;
}
else if (iconString.equals("partly-cloudy-night")) {
iconId = R.drawable.cloudy_night;
}
return iconId;
}

and here is the forecast.java file in which I call the getIconId method.
public class Forecast {

private Day[] mDailyForecast;

}

mCurrent = current;

return mHourlyForecast;
}
public void setHourlyForecast(Hour[] hourlyForecast) {
mHourlyForecast = hourlyForecast;
}
public Day[] getDailyForecast() {
return mDailyForecast;
}
public void setDailyForecast(Day[] dailyForecast) {
mDailyForecast = dailyForecast;
}
public static int getIconId(String iconString) {
// clear-day, clear-night, rain, snow, sleet, wind, fog, cloudy, partly-cloudy-day, or partly-cloudy-night.
int iconId = R.drawable.clear_day;
if (iconString.equals("clear-day")) {
iconId = R.drawable.clear_day;
}

iconId = R.drawable.clear_night;

57,712 PointsIs there any chance you've got this in version control? If you can push this up to Github that would really help as I can replicate the error here and chase down the issue more easily.

1,032 PointsI am familiar with but not versed in Github. Im going to catch up on it with some lessons and will report back when I have it uploaded to Github.
Steve Hunter
57,712 PointsOK cool - look me up when you get there
Or use Bitbucket which is better as it offer free private repos. Github doesn't so your hashes are visible to everyone.
