What kind of problems do you have? It's not clear only after reading post title and looking to your code.

[daviscabral]

Please, try to wrap your full code for better reading.

But from what I am getting - this might be an issue with react-navigation (exiting or not exiting from initial screen when on Android). Is that the issue?

[ShawSmall]

yes,i have the issue.

[sitompul]

I have the same issue, here is my router

const ConnectRouter = connect()(Router);

const Routes = () => (
  <ConnectRouter>
    <Stack key="root">
      <Scene key="launchScreen" component={LoadingFull} hideNavBar />
      <Scene key="login" component={LoginForm} hideNavBar type={ActionConst.RESET} />
      <Scene key="lostPassword" component={LostPasswordForm} hideNavBar />
      <Scene key="dashboard" component={Dashboard} hideNavBar type={ActionConst.RESET} />
      <Scene key="search" component={SearchResult} hideNavBar />
      <Scene key="detail" component={detail} hideNavBar />
      <Scene key="notifications" component={Notifications} hideNavBar />
      <Scene key="errorResult" component={ErrorResult} type={ActionConst.RESET} hideNavBar />
    </Stack>
  </ConnectRouter>
);

When i'm at my reset scenes, nothing happened when i touch the physical android button, but when im at my normal scenes, the app will exit if i press the physical back button.
im using version 4.0.0-beta.24.

[nishiltamboli]

@sitompul I have the exact same issue! Did you find a fix for this? I am planning to use an older version instead but I dont intend to do that. I like the platform specific overrides of Screen to Screen nav animation! And what version of RN are you using? Mine is 0.50.4. Also my RNRF version is the same as yours.

[rajeshbatth-gommt]

Any update on this issue?? Even I'm getting this on 4.0.0-beta.24

[sitompul]

@rajeshbatth-gommt @nishiltamboli look for @Blapi 's comment at #2737

[aksonov]

Please check Example project - I checked hardware back and it works fine.

[ShawSmall]

i have solved the problem;
_backAndroidHandler = () => {
const scene = Actions.currentScene;
// alert(scene)
if (scene === 'index' || scene === '_Main' || scene === 'Main') {
BackHandler.exitApp();
return true;
}
Actions.pop();
return true;
};
