I known i forgot style (eg.. style.xml more...values-v14 forgot )

<org.jraf.android.backport.switchwidget.Switch
    android:layout_width="wrap_content"
    style="@style/Widget.Holo.CompoundButton.Switch"
    android:layout_height="wrap_content" />

The error occured when have no style attr....
you can use

  style="@style/Widget.Holo.CompoundButton.Switch"

as default

Set up some breakpoints and it seems the solution from here solves the issue.

Other bug report on NPE on Android 2.3.3

Don't understand if there is something wrong, or just a wrong way to fix a problem, but it worked for me.

However, now I've found another issue. The switcher is stuck, it stays on OFF no matter what, it doesn't move.

@Arise

I found the param text is null of the function...

 private Layout makeLayout(CharSequence text) {
    return new StaticLayout(text, mTextPaint, (int) Math.ceil(Layout.getDesiredWidth(text, mTextPaint)),   Layout.Alignment.ALIGN_NORMAL, 1.f, 0, true);
}

The param from styleable text_on text_off ... so need style(ps: your style.xml may have many... )

mTextOn = a.getText(R.styleable.Switch_textOn);
mTextOff = a.getText(R.styleable.Switch_textOff);

I will have a look at this this week end :)
See if I can figure it out.

Any progress here? I'd like to use it in project but I see some heavy development for latest Android versions is necessary ...

I just checked.
It seems that you are not using the theme in your Activity or Application.
I just updated the readme file to clarify this point.
Please tell me if you are still having problems after updating your manifest.
