What's the NoSaveStateFrameLayout?

Question

I\'ve been reading about layout optimization from the Android Dev blogs and I\'ve been using hierarchyviewer to see where I can possibly flatten or merge layouts/elements. B

Answer 1

It's an implementation detail of the support library's fragment implementation. This is the comment from it:

/**
 * Pre-Honeycomb versions of the platform don't have {@link View#setSaveFromParentEnabled(boolean)},
 * so instead we insert this between the view and its parent.
