This refers to line: this.marginRight = attributes.getDimensionPixelSize(5, 30); and I have tried overriding marginRight in both XML and code.

I have tried copying the sample dimens.xml and using that but it doesn't work. I have tried in both Kotlin and Java.

draggable_panel.setFragmentManager(supportFragmentManager)
draggable_panel.setTopFragment(youtubeFragment)
draggable_panel.setBottomFragment(EmptyFragment())
draggable_panel.isClickToMaximizeEnabled = truedraggable_panel.setEnableHorizontalAlphaEffect(true)
draggable_panel.setTopFragmentMarginBottom(resources.getDimension(R.dimen.top_fragment_margin).toInt())
draggable_panel.setTopFragmentMarginRight(resources.getDimension(R.dimen.top_fragment_margin).toInt())
draggable_panel.initializeView()

To avoid the issue I downloaded a local copy of the repository and removed the NineOldAndroids dependency and it worked as expected.

This is just a band-aid and am curious for a proper fix.
