ReactNative ActivityIndicator not showing when animating property initiate false

Question

I\'m playing with react native and got a strange behaviour.

When I try to show a ActitvityIndicator for Android setting its animating property

Answer 1

The transition of animating from false to true is too slow on Android. But you can force a re-render using the key prop:

When props.animating changes from false to true, they key also changes. This forces a re-render, meaning that a new component is rendered with animating = true, which will instantly start your spinner.
