    <p>Ok, I'm getting an <code>IllegalArgumentException</code> at a point where it shouldn't. </p> <p>I have a custom extension of <code>Account</code> that is saved using the AccountManager:</p> <pre><code>// Method inside a custom extension of Account public boolean save(AccountManager manager) { removeAll(manager); boolean result = manager.addAccountExplicitly(this, null, toBundle()); manager.setUserData(this, KEY_1, value1); manager.setUserData(this, KEY_2, value2); manager.setUserData(this, KEY_3, value3); return result; } </code></pre> <p>The keys are constant String values but app still throws:</p> <pre><code>java.lang.IllegalArgumentException: key is null </code></pre> <p>I have to say that I'm only attaching the user data in this fashion because using: </p> <pre><code> manager.addAccountExplicitly(this, null, toBundle()); </code></pre> <p>didn't seem to attach the values. Do the keys require a special name pattern?</p> <p>Anybody had this problem before?</p> <hr> <p><strong>Update:</strong></p> <p>It gets thrown inside the <code>manager.setUserData()</code> which looks like this (Android code):</p> <pre><code>public void setUserData(final Account account, final String key, final String value) { if (account == null) throw new IllegalArgumentException("account is null"); if (key == null) throw new IllegalArgumentException("key is null"); try { mService.setUserData(account, key, value); } catch (RemoteException e) { // won't ever happen throw new RuntimeException(e); } } </code></pre> <p>When I "walk" into this method with eclipse I get this in the debug perspective:</p> <p><img src="https://i.stack.imgur.com/83KwX.png" alt="enter image description here"></p> <p>The values aren't null >o&lt;</p>

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.
