React-native Atempt to invoke virtual method 'double java.lang.double.doublevalue()' on a null object reference (2019)

Question

Seems to be a problem with react-native-reanimated

Answer 1

Seems to be a problem with react-native-reanimated 1.5.0 which was released a few hours ago. Downgrading to 1.4.0 solved it

"react-native-reanimated": "1.4.0"

Answer 2

In my particular case it was that a call to ToastAndroid.show(text, timeout) was missing the timeout parameter.

For these kinds of scenarios I recommend migrating to react native with typescript.
