You must add backAndroidHandler in Router

[Maxitk]

my version is 4.0.0-beta.23
i have add Router,but it doesn't run backAndroidHandler when i press back

[aksonov]

@Maxitk Please check latest master now.

[Maxitk]

@aksonov ok，i will try it tomorrow,thanks...

[Maxitk]

@aksonov i have tried it a moment ago,but the same as before
I have deleted other 'backHandler' in my code and I try to do two things :
1、I add <Router backAndroidHandler...
2、I add backHandler.addEventListener in initial page
both of them didn't work

[kaixinfu]

please try it.<Router backAndroidHandler={() => {}}>
