    <p>This is very interesting, but it is not Android-specific, I think.</p> <p>I wrote this small test in plain Java:</p> <pre><code> public class ReflectionTest { public static void main(String[] args){ Method[] m = ReflectionTest.class.getDeclaredMethods(); for (Method method : m) { System.out.println(method.getName()); } try { Method m1 = ReflectionTest.class.getDeclaredMethod("d0", int.class, boolean.class); if(m1 != null){ System.out.println("m1 found!"); } } catch (Exception e) { e.printStackTrace(); } try { Method m2 = ReflectionTest.class.getDeclaredMethod("d0", Integer.TYPE, Boolean.TYPE); if(m2 != null){ System.out.println("m2 found!"); } } catch (Exception e) { e.printStackTrace(); } try { Class&lt;?&gt;[] carr = m[1].getParameterTypes(); Method m3 = ReflectionTest.class.getDeclaredMethod("d0", carr); if(m3 != null){ System.out.println("m3 found!"); } } catch (Exception e){ e.printStackTrace(); } } public void d0(int a, boolean b){ } } </code></pre> <p>In eclipse, if I debug it, the three m1,m2 and m3 are printed. However, if I run it, a <code>NoSuchMethodException</code> is thrown when trying to get m3.</p> <p>UPDATES:</p> <ul> <li>Tested running with jre 7 under linux, and all three m1,m2 and m3 were printed. Perhaps is a problem with jre6? Or is eclipse run configuration?</li> <li>Changed <code>carr</code> declaration to use method 0 instead of 1: <code>Class&lt;?&gt;[] carr = m[0].getParameterTypes();</code> as Gray suggested. Now it runs ok but throws exception in debug mode. This means different method order for the returned array <code>m</code>.</li> <li>Update #2 confirmed, I've included a for loop to print the method names. In run mode the order of the method array is reversed compared to debug mode.</li> </ul>

    1. COYour test works fine for me under JRE6 under MacOSX. Maybe a particular JRE version number?

    2. COHave same problem: in eclipse works when debuging, throws exception when running. Win7 64bit, JRE 1.6.0_26-b03 and JDK 1.6.0_20-b02. getDeclaredMethods must have a problem, as it searches for `d0([Ljava.lang.String)`, so a method with String[] argument

    3. CO@Gray That maybe the case. I'm running JRE 1.6.0_07-b06, eclipse 3.6 helios, Windows XP 32bit.

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.
