I am making a layout which contains CardView and nested Linear Layouts. When I made the layout for the first time it works fine and the preview window is also displaying the changes. After a day when I open android Studio the preview window keep saying "Waiting for build to finish". So I thought that it is bug related to IDE.
I tried all the solutions that are recommended here:
But I found out that issue was with my layout beacuse I deleted the layout rebuild the project and preview works fine again. Now I tried to make the same layout again from start but it still happens again. It is very strange for me as my layout is simple, I have created Similar layouts before with no issue whatsoever. I am using the Latest Api Version 29, with latest build tools and latest Android Studio.
Here is my layout code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

The cause of the issue is Slider. I'm trying to solve it too but still unsuccessful.
Sorry for late reply... Use AppCompatSlider
or simply replace it by the traditional Seekbar
. I also faced the same issue with material slider.
