Xamarin.Forms controls disappear when navigate back to a page on Android

Issue

I'm building an application with Xamarin.Forms and a Portable Class Library. The app can be used on Android, iOS and UWP.

I made a page that works correct on each platform:

After clicking an item in the ListView, a new page will be opened:

Navigation.PushAsync(new CourseInfoPage(ID));

When that page is opened and I press the "Back-button" and navigate back to the page shown above, it looks like this:

So some controls disappear when I'm navigating (away and then) back to this page. This ONLY happens on Android. If I click somewhere in the white area, the controls still function but I don't get to see them.

What did I try:

protected override void OnAppearing()
{
    base.OnAppearing();
    Content = getContentPage();
}


protected override void OnDisappearing()
{
    base.OnDisappearing();
    this.Content = null;
}

But this doesn't solve the problem.

How do I fix this? What is the problem?

Solution

If you want to go back to previous Page you can use

PopAsync()

or

PopModalAsync()
