I've got a few classes that implement Parcelable and some of these classes contain each other as properties. I'm marshalling the classes into a Parcel to pass them between activities. Marshalling them TO the Parcel works fine, but when I try to unmarshall them I get the following error:
...

The LayoverType
class (where it's failing):
public class LayoverType implements Parcelable {
protected LocationType location;
protected long start;
protected long end;
public LayoverType() {}
public LocationType getLocation() {
return location;
}
public void setLocation(LocationType value) {
this.location = value;
}
public long getStart() {
return start;
}
public void setStart(long value) {
this.start = value;
}
public long getEnd() {
return end;
}
public void setEnd(long value) {
this.end = value;
}
// **********************************************
// for implementing Parcelable
// **********************************************
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeParcelable(location, flags);
dest.writeLong(start);
dest.writeLong(end );
}
public static final Parcelable.Creator<LayoverType> CREATOR = new Parcelable.Creator<LayoverType>() {
public LayoverType createFromParcel(Parcel in) {
return new LayoverType(in);
}
public LayoverType[] newArray(int size) {
return new LayoverType[size];
}
};
private LayoverType(Parcel dest) {
location = (LocationType) dest.readParcelable(null); // it's failing here
start = dest.readLong();
end = dest.readLong();
}
}
Here's the LocationType
class:
public class LocationType implements Parcelable {
protected int locid;
protected String desc;
protected String dir;
protected double lat;
protected double lng;
public LocationType() {}
public int getLocid() {
return locid;
}
public void setLocid(int value) {
this.locid = value;
}
public String getDesc() {
return desc;
}
public void setDesc(String value) {
this.desc = value;
}
public String getDir() {
return dir;
}
public void setDir(String value) {
this.dir = value;
}
public double getLat() {
return lat;
}
public void setLat(double value) {
this.lat = value;
}
public double getLng() {
return lng;
}
public void setLng(double value) {
this.lng = value;
}
// **********************************************
// for implementing Parcelable
// **********************************************
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt (locid);
dest.writeString(desc );
dest.writeString(dir );
dest.writeDouble(lat );
dest.writeDouble(lng );
}
public static final Parcelable.Creator<LocationType> CREATOR = new Parcelable.Creator<LocationType>() {
public LocationType createFromParcel(Parcel in) {
return new LocationType(in);
}
public LocationType[] newArray(int size) {
return new LocationType[size];
}
};
private LocationType(Parcel dest) {
locid = dest.readInt ();
desc = dest.readString();
dir = dest.readString();
lat = dest.readDouble();
lng = dest.readDouble();
}
}
Update 2: As far as I can tell it's failing at the following bit of code (from Parcel's source):
Class c = loader == null ? Class.forName(name) : Class.forName(name, true, loader);
Why is it not able to find the class? It both exists and implements Parcelable
.
Because this was not answered in "answer" but in comment I will post an answer: As @Max-Gontar pointed you should use LocationType.class.getClassLoader() to get the correct ClassLoader and get rid of ClassNotFound exception, i.e.:
in.readParceleable(LocationType.class.getClassLoader());
