    <p>I'm currently causing an <code>IndexOutOfBoundsException</code> that I can't seem to track down. I have a Spinner that is populated by a <code>String[]</code>. Depending on the manufacturer of the device, that <code>String[] (and hence Spinner object)</code> will have either 3 values or 1 value. </p> <p>I store the saved Spinner selection as an <code>int</code> in the <code>SharedPreferences</code> and load it up upon the <code>Activity</code> creation.</p> <p>In cases where the Spinner will only have 1 value, if it loads up the <code>SharedPreferences</code> and the saved value is <code>2</code>, I set that spinner to select item position 2, it will crash (obviously). I am trying to catch that exception so that I can then just set it to <code>0</code>, but I can't ever seem to catch that <code>Exception</code>. </p> <p>The code structure is as so:</p> <pre><code>Populate Spinner according to something Load up Saved Preferences Check some value of saved preferences try{ Set Spinner with that Preference } catch(Exception e) { Set Spinner with default value of 0 } </code></pre> <p>StackTrace:</p> <p><code>10-18 12:49:32.885: E/AndroidRuntime(15327): FATAL EXCEPTION: main 10-18 12:49:32.885: E/AndroidRuntime(15327): java.lang.IndexOutOfBoundsException: Invalid index 2, size is 1 10-18 12:49:32.885: E/AndroidRuntime(15327): at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251) 10-18 12:49:32.885: E/AndroidRuntime(15327): at java.util.ArrayList.get(ArrayList.java:304) 10-18 12:49:32.885: E/AndroidRuntime(15327): at android.widget.ArrayAdapter.getItem(ArrayAdapter.java:337) 10-18 12:49:32.885: E/AndroidRuntime(15327): at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:390) </code></p>

    1. COIs it possible the exception was thrown outside the try block? Can't tell if that's case from what you have posted here.

    2. COIt is certain that the error is caused by setting the spinner with an index that is outside of it's available choices, as when I remove it, it's all fine. I even wrapped the entire onCreate() (from which this section of code is invoked from) to catch the exception, but it still does not catch it.

    3. COInteresting. One level up Exception is the Java Throwable. Wonder if that allows you to catch it.

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.
