backAndroidHandler/onBackAndroid/onExitApp not triggered on Actions.refresh

[pewh]

Version

Tell us which versions you are using:

• react-native-router-flux v3.7.0
• react-native v0.37

My case is: if this.state.isValueChanged is false, show save confirmation dialog if press back.

componentWillMount() {
  Actions.refresh({
      title: 'Kontak Restoran',
      renderRightButton: this.renderUpdateButton,
      backAndroidHandler: this.handleBackAndroidHandler,
      onBackAndroid: this.handleBackAndroidHandler,
      onExitApp: this.handleBackAndroidHandler,
  })
}

handleBackAndroidHandler =  () => {
    console.log('foo')
}

renderUpdateButton = () => {
  console.log('bar')
}

Expected behaviour

on page loaded, show foo in console.
when back android button pressed, show bar in console.

Actual behaviour

on page loaded, show foo in console.
when back android button pressed, console didn't show bar
I already test with debugger, and function not triggered.

I didn't know about this functionality. In my app, I'm currently using

BackAndroid.addEventListener('hardwareBackPress', () => Actions.pop());

Yes, I'm using hardwareBackPress event too. But it's not enough because my case is to trigger something before back button in device or navbar is pressed .

me too。 use onBackAndroid cannot refresh 。 so when action.pop need refesh I use RCTDeviceEventEmitter.emit()
componentWillUnmount() {
if(device.android){
RCTDeviceEventEmitter.emit('update'Id)
}
}
