Expo GLView in managed app doesn't trigger onContextCreate

Expo SDK
1

I’m trying to use GLView to draw some animation, but the GLView doesn’t display anything. I try to add a console.log at the start of GLView’s onContextCreate, and nothing was logged, which means onContextCreate is not called. Do I need some configuration on my phone, or it was obsoleted?

Here’s a link for snack:

Android version is not showing anything.
