[android] Cannot select item with numeric value zero

[vincicat]

similar to #592

I encounter some bugs after upgrade to RN 0.76...after some investigation I found it only happens on Android and is related to the value prop of <Picker.Item>:

demo

iOS will convert everything into string so it is fine (even with empty string), while android will keep the origin type of value so the selection of any "js falsy" value (numeric zero, empty string, undefined value etc) will not fire the onValueChange event.

Please help.
