WeatherApp -> click on "daily button" -> app crash ( "Class not found when unmarshalling: Europe/Warsaw" )

Hi

Can you help me with this strange for me error in code ?:)

When I clicked daily button I cached this Exception:

E/Parcel: Class not found when unmarshalling: Europe/Warsaw java.lang.ClassNotFoundException: Invalid name: Europe/Warsaw

from stacktrace : com.example.tomas.weatherapp.ui.DailyForecastActivity.onCreate(DailyForecastActivity.java:39) it's: ''' 39: Parcelable[] parcelables = intent.getParcelableArrayExtra(MainActivity.DAILY_FORECAST); '''

HALF SOLVE

I forgot to write this line in Day.java: mIcon = in.readString();

public void writeToParcel(Parcel parcel, int i) {
parcel.writeLong(mTime);
parcel.writeString(mSummary);
parcel.writeDouble(mTeperatureMax);
parcel.writeString(mIcon);
parcel.writeString(mTimeZone);
}

must be the same order :

public Day(Parcel in) {
    mTime = in.readLong();
    mSummary = in.readString();
    mTeperatureMax = in.readDouble();
    mIcon = in.readString();
    mTimeZone = in.readString();
}
