Disable or prevent multitouch in Activity

if someone still searching for best solution, put in the xml the following code :

android:splitMotionEvents = false 

I did it like this :

@Override
public boolean onTouchEvent(MotionEvent event) {
    // TODO Auto-generated method stub

    if(event.getPointerCount() > 1) {
        System.out.println("Multitouch detected!");
        return true;
    }
    else
        return super.onTouchEvent(event);
}

I think you can override onTouchEvent for any view.

The easiest way I found to force single touch across an entire app is to set it using a theme:

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowEnableSplitTouch">false</item>
    <item name="android:splitMotionEvents">false</item>
</style>

Manifest:

  <application
        android:label="@string/app_name"
        android:theme="@style/MyTheme" >
