    <p>I just added preferences to my app and it fails to open (i.e shows a black screen or stops unexpectedly). By commenting out some lines, I found out that the problem was in the initialization of the preferences.</p> <pre><code>//some imports here public class MyApp extends Activity { ..... SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this); ...... } </code></pre> <p>Once I comment out that line, everything (except preferences) works well. Logcat showed me some errors (like 20) but now it isn't showing errors but the app still doesn't load.</p> <p>EDIT: This is the preferences.xml (under xml folder) </p> <pre><code>&lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;ListPreference android:key="format" android:title="Saving Format" android:summary="Select the file format" android:defaultValue="jpg" android:entries="@array/format" android:entryValues="@array/formatValues" /&gt; &lt;/PreferenceScreen&gt; </code></pre> <p>And here is the array.xml under layout folder </p> <pre><code>&lt;resources&gt; &lt;string-array name="format"&gt; &lt;item name="jpg"&gt;JPEG&lt;/item&gt; &lt;item name="gif"&gt;GIF&lt;/item&gt; &lt;/string-array&gt; &lt;string-array name="formatValues"&gt; &lt;item name="jpg"&gt;.jpg&lt;/item&gt; &lt;item name="gif"&gt;.gif&lt;/item&gt; &lt;/string-array&gt; &lt;/resources&gt; </code></pre> <p>Ironic how I cant manage to make logcat give me Errors now. It just does not load. If I remove that single line (SharedPreferences....) it works normally.</p> <p>Any ideas what might be wrong?</p> <p>Thanks!</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.

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