Stormy app crashed (android.os.BadParcelableException: ClassNotFoundException when unmarshalling)

Hi all,

I have been trying to troubleshoot this problem for the whole night.I was able to pinpoint where the app crashes using the debugger.

It is this line:

Parcelable[] parcelables = intent.getParcelableArrayExtra(MainActivity.HOURLY_FORECAST);

This is the only error message I could find on the debugger :

"android.os.BadParcelableException: ClassNotFoundException when unmarshalling:"

Thanks in advance.

I've solved it on my own.

Apparently, having parcel read/write in different order can cause the error which is "Consumer closed input channel or an error occurred"

In the Hour class, the order in which you "write" in the method "writeToParcel" must match the order you wrote in private Hour(Parcel in) object.

    public void writeToParcel(Parcel dest, int flags) {
        dest.writeLong(mTime);
        dest.writeDouble(mTemperature);
        dest.writeString(mSummary);
        dest.writeString(mIcon);
        dest.writeString(mTimeZone);

    }
    private Hour(Parcel in){
        mTime=in.readLong();
        mTemperature=in.readDouble();
        mSummary=in.readString();
        mIcon=in.readString();
        mTimeZone =in.readString();
    }
