Sergey Shakhnazarov commented on CB-11304:
------------------------------------------

[~rdesimone], can you try if an option [{{<preference name="SplashShowOnlyFirstTime" value="false"
/>}}|https://github.com/apache/cordova-plugin-splashscreen/#android-quirks] helps?

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Android
>    Affects Versions: 6.0.0
>         Environment: Cordova 6.0.0
> cordova-android@5.1.1
> Mac OSX
> Android Studio 2.1
> Nexus 4 (Android 4.4.4)
> Nexus 6p (Android 6.0.1)
>            Reporter: Roberto De Simone
>            Priority: Critical

> Using the backbutton to suspend (exit) the app, something is going wrongly. 
> When later resuming the app - through the app list or by selecting the app icon - the
app loads again but without splash screen. When the JS is heavy, like an Ionic 2 app there
is a white screen for several seconds which looks very ugly. When leaving the app with the
hardware "home" button, the app suspends correctly.
> This can be reproduced with the simplest possible Cordova app.
> 1. cordova create test com.mydomain.test test
> 2. cd test
> 3. cordova add platform android
> 4. cordova run android (on a device)
> 5. Press the backbutton
> 6. Switch to app list
> 7. Select the app
> -> for a very short time a white screen is visible - the time needed to load the JS.
As the simplest app has very little JS, the effect is difficult to see on fast devices like
a Nexus 6p. If you add heavy JS - like Ionic 2, then the effect is very well visible also
on fast devices.
> 8. Now, select the "home" button
> 9. Switch to app list
> 10. Select the app
> -> the app resumes without loading the JS again - no white screen.
> (Also to mention: the effect is the same when listening to the "backbutton" event and
trying to exit the app with "navigator.app.exitApp() ")
