[syg4806]

Hi. I'm using this SlidingDrawer very usefully. But I found a bug when I use Pixel 2 API 24 Emulator I put some textviews Inside of the Sliding drawer, and I change the text every second. when I test it with API 28, It's work well. But in Pixel 2 API 24, it doesn't work. My XML code looks like this..
