> On Android, there is a small race condition in the code to hide the splash screen when a fade out is used. It may only be visible in certain edge cases, but the net result is that the app will crash.
> Specifically, if multiple calls come in to {{removeSplashScreen}} in a row, it's possible for the first call to null out {{splashImageView}} before the second call uses it (but after the second call tests for {{splashDialog == null}}), because of the animation delay.
> Crashing code: https://github.com/apache/cordova-plugin-splashscreen/blob/master/src/android/SplashScreen.java#L219
> My repro for this scenario is due to having a native dialog box that appears if we have a network connection error when trying to connect to the starting URL (in my case, it is a remote URL). The dialog box has a 'retry' button which allows the user to retry the network request. When the user does this, we tell the webview to load a new URL; the webview then re-initializes the plugin manager, which in turn sends onPause and onDestroy events to the Splash Screen plugin. It's this sequence of events, which, in quick succession, can trigger the crash.
