Open window very slow (Android)

Hi,

I'm finishing my app, it actually works very well on both platforms (iOS and Android)

But I'm facing a problem on Android. My app is divided in 5 windows, an user interaction one 1 window may impact the 4 other windows (doing an update, refresh...).

When on iOS, I open all window at launch and then hide all, to make the navigation faster. But on android, we can't use window.hide() so when and android user change window, it does actuallWindow.close() and then newWindow.open(). But this process is very slow, is there a way to handle better a windowed based app ?

Thank you, any help would be appreciated.
