[android-developers] Re: debug blues

Yes.

The code on the device (Nexus 7) has debug info that tells Eclipse the line-numbers of the source-code. If your source-code (android-16) is out-of-date, these line-number don't match up and Eclipse shows you something wrong (correct line-number, wrong source-version).

It seems to work if I do "Edit Source Lookup" and change it to android-17.  Is it 17 because the Nexus 7 is running 4.2.1?


I built targeted for 16.

I'm stepping thru my source.

I have a call to invalidate().

I stepped into it, and attached the android source (version 16).

However, it went here:

    /**
     * Used to indicate that the parent of this view should be invalidated. This functionality
     * is used to force the parent to rebuild its display list (when hardware-accelerated),
     * which is necessary when various parent-managed properties of the view change, such as
     * alpha, translationX/Y, scrollX/Y, scaleX/Y, and rotation/X/Y. This method will propagate
     * an invalidation event to the parent.
     *
     * @hide
     */
    protected void invalidateParentIfNeeded() {
        if (isHardwareAccelerated() && mParent instanceof View) {
            ((View) mParent).invalidate(true);
        }
    }



Why did it go to the function invalidateParentIfNeeded() instead of the function invalidate()?
