Try checking if (myMenu != null), since, you know, you probably want a valid
object to add stuff to.

1. no virtual keyboard available

I have developed an app that uses setTextFilterEnabled(true).  It
works perfectly on my G1.  My partner has a new MyTouch phone that
does not have a real keyboard.  He cannot use this functionality at
all.  He tried holding down the menu key(and so have I) but the
keyboard does not appear.  Without a keyboard, this app is dead on
arrival.  I am trying the following code to no avail.

                setListAdapter(new ArrayAdapter<String>(this,
                        android.R.layout.simple_list_item_1, data ));

                final InputMethodManager imm =
                            imm.showSoftInput( null, 0);


2. How can I know all attributes I can use in declare-styleable attr tag?

In ApiDemos, I can see how to define my custom elements to use in
layout resources. That is :

<declare-styleable name="LabelView">
        <attr name="text" format="string" />
        <attr name="textColor" format="color" />
        <attr name="textSize" format="dimension" />

But that is just a simple demo. I can define like this:

<declare-styleable name="MyWidget">
<attr name="textX" format="integer" min="0"/>

I use the "min" attribute, I want to know all the attibutes I can use
and how to use, where is the document?
