    <p>I've got a few classes that implement <a href="http://developer.android.com/reference/android/os/Parcelable.html" rel="noreferrer">Parcelable</a> and some of these classes contain each other as properties. I'm marshalling the classes into a <a href="http://developer.android.com/reference/android/os/Parcel.html" rel="noreferrer">Parcel</a> to pass them between activities. Marshalling them TO the Parcel works fine, but when I try to unmarshall them I get the following error:</p> <pre><code>... AndroidRuntime E Caused by: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: schemas.Arrivals.LocationType AndroidRuntime E at android.os.Parcel.readParcelable(Parcel.java:1822) AndroidRuntime E at schemas.Arrivals.LayoverType.&lt;init&gt;(LayoverType.java:121) AndroidRuntime E at schemas.Arrivals.LayoverType.&lt;init&gt;(LayoverType.java:120) AndroidRuntime E at schemas.Arrivals.LayoverType$1.createFromParcel(LayoverType.java:112) AndroidRuntime E at schemas.Arrivals.LayoverType$1.createFromParcel(LayoverType.java:1) AndroidRuntime E at android.os.Parcel.readTypedList(Parcel.java:1509) AndroidRuntime E at schemas.Arrivals.BlockPositionType.&lt;init&gt;(BlockPositionType.java:244) AndroidRuntime E at schemas.Arrivals.BlockPositionType.&lt;init&gt;(BlockPositionType.java:242) AndroidRuntime E at schemas.Arrivals.BlockPositionType$1.createFromParcel(BlockPositionType.java:234) AndroidRuntime E at schemas.Arrivals.BlockPositionType$1.createFromParcel(BlockPositionType.java:1) ... </code></pre> <p>The <code>LayoverType</code> class (where it's failing):</p> <pre><code>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&lt;LayoverType&gt; CREATOR = new Parcelable.Creator&lt;LayoverType&gt;() { 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(); } } </code></pre> <p>Here's the <code>LocationType</code> class:</p> <pre><code>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&lt;LocationType&gt; CREATOR = new Parcelable.Creator&lt;LocationType&gt;() { 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(); } } </code></pre> <p><strong>Update 2</strong>: As far as I can tell it's failing at the following bit of code (from <a href="http://www.netmite.com/android/mydroid/frameworks/base/core/java/android/os/Parcel.java" rel="noreferrer">Parcel's source</a>):</p> <pre><code>Class c = loader == null ?

    1. COCould you post the code for the LocationType class? It could be the write method in that class is not correct in some way.

    2. CO@MpKamowski: I added the Parcelable bits from LocationType. The only other stuff in either class is just getters/setters.

    3. COIs it possible that the package for which LocationType is a apart of is not visible in the code where it is being unmarshalled?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
