ionic-framework: bug: Nav-bar sometimes disappears after destroying and re-launching the app

Type: bug

Platform: mobile webview

# Tabs seed

I wrote an app based on tabs seed. The nav-bar seems to disappear sometimes after I close my app and relaunch it.

Steps

I launch my app, login and display the dashboard screen.
Close the app or reinstall it with (ionic run ios; ionic run android)
Sometimes app opens but without nav-bar (it’s hidden)

I use $state.go with dashboard cache disabled. The issue is random and it happens on both platforms. This is production showstopper for me. I try to find some workaround but the FIX is needed here. To be more precise, the nav bar gets the hide class and the whole ion-view is repositioned like it was no nav-bar.

I found that these code will make this kind of problem fly away

$scope.$on('$ionicView.enter', function(e) {
    $ionicNavBarDelegate.showBar(true);
});

My solution is just show it whenever view is entered.

Here’s a video where I show how this bug can be reproduced in my app: http://iver.io/stuff/ag/WP_20150411_001.mp4

Here’s what I do: I’m inside Chrome and I tap a deep link to open the app. Then I tap the back button twice. The second tap closes the app and I see Chrome again. Then I click the deep link again. The app opens once again. Problem: The nav-bar is not visible. Happens every time I do this, i.e. it’s not random.

The second back button tap (the one that closes the app) is actually calling navigator.app.exitApp();

OS: Android 4.1

Edit: I don’t know if it’s relevant, but the first view (the one with the list of badminton events) has hide-nav-bar=true

I found some workaround, but it’s not ideal for all apps. I replaced the ion-nav-bar with fixed ion-header-bar from http://ionicframework.com/docs/api/directive/ionHeaderBar/ and it does not disappear. It was possible because my app was not using any features from nav-bar like history. Happily the app can go to production, but IMHO the bug is a critical issue for ionic stable release.
