    <p>I need to deserialize object but when I'm reading object using readObject i get such exception:</p> <pre><code>Exception raised: java.lang.Enum; Incompatible class (SUID): java.lang.Enum: static final long serialVersionUID =0L; but expected java.lang.Enum: static final long serialVersionUID =0L; </code></pre> <p>Here's the code:</p> <pre><code>public static void restore3x(PersistentHistory h, DictManager dictManager) throws Exception{ SharedPreferences prefs = tryToGuess(h.mContext); if (prefs == null) return; Log.e("shdd","Found history!"); String history = prefs.getString("History", null); ObjectInputStream objIn = null; try { //prepare objIn = new ObjectInputStream(new ByteArrayInputStream(Base64.decode(history))) { @Override protected ObjectStreamClass readClassDescriptor() throws IOException, ClassNotFoundException { ObjectStreamClass osc = super.readClassDescriptor(); if (osc.getName().contains("slovoed")) { try { Field f; f = osc.getClass().getDeclaredField("svUID"); f.setAccessible(true); Log.e("shdd","Setting serialVersionUID"); f.setLong(osc, serialVersionUID); Log.e("shdd","Set ok"); f = osc.getClass().getDeclaredField("className"); f.setAccessible(true); Log.e("shdd","Setting class name"); f.set(osc, WordItem.class.getName()); Log.e("shdd","Set ok"); } catch (Exception e) { } } return osc; } }; //add to DB Log.e("shdd","Getting items"); Collection&lt;WordItem3x&gt; items = (Collection&lt;WordItem3x&gt;) objIn.readObject(); Log.e("shdd","Got ok"); if (items.isEmpty()) return; Log.e("shdd","List's not empty"); long timeSeconds = System.currentTimeMillis()/1000; for (WordItem3x w : items) { if (w.getWord() == null || w.getWord().length() == 0 || w.getIndexList() == 0) continue; Log.e("shdd","Adding word"); h.add(w.getWord(), w.getIndexList(), timeSeconds--); } } catch (Exception e) { Log.e("shdd","Exception raised: " + e.getMessage()); throw e; } finally { try { if (objIn != null) objIn.close(); } catch (Exception e) {} //prefs.edit().remove("History").commit(); } } </code></pre> <p>I have no idea what's wrong. Maybe someone has seen such exceptions?</p> <p>Here's WordItem3x readObject method:</p> <pre><code>private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException { Log.e("shdd", "Reading object"); in.defaultReadObject(); int val1 = in.readInt(); int val2 = in.readInt(); if (val1 != -1 &amp;&amp; val2 != -1) { direction = new Direction(val1, val2); } else direction = null; val1 = in.readInt(); if (val1 != -1) typeList = eWordListType.values()[val1]; else typeList = null; } </code></pre> <p>But as i can see it's not ever called.</p>

    1. COWhat is wrong is undoubtedly all that stuff where you fiddle around with the class descriptor. What's all that suppose to be for?

    2. COIt's not my code, but i found it's strange too. But the issue isn't here. WordItem3x has been chainging from version to version of the app so looks like it's some kind of "magick" to get it work.

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.

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