I'm working on a library that would allow you to use Xamarin.Forms Pages with the native navigation service provided by MvvmCross.
The Android implementation has an issue when using Fragments. If you look at the library / sample project a crash occurs when you press the back button after loading the second fragment.
Steps to Reproduce:
Launch App
Press "Fragment Navigation Stack"
Press "Next"
Press the back button.
I've been pulling my hair out trying to figure out how to stop this error from occurring.
The app crashes with this error.
Java.Lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
--- End of managed Java.Lang.IllegalStateException stack trace ---

I have links leading to hashed locations that reference IDs . When I press links relatively quickly i get this error :
Unhandled Runtime Error
Error: Cancel rendering route
What is the solution to this problem ? Maybe use Router events like 'hashChangeStart'/'hashChangeEnd' ?enter image description here

Has anybody found same issue
I am using the iAd suite with storyboards from Apple, as per this link...
Apple iAd Storyboard documentation
It all works fine until I turn autolayout on. It builds fine but crashes on running. The output I get is:

I know it is something to do with the subviews in storyboard but I dont know how to correct this error. I am pretty new to iOS and trying to teach myself so any help is appreciated. Many Thanks
Add:
[self.view layoutIfNeeded];
to the end of this method
- (void)viewDidLayoutSubviews
inside your BannerViewController
this problem block me for two days. When i launch my Flex Air program, then if I press TAB key, it will crash and show

how to fix? thanks.
I have several viewControllers controlled by a navigation controller.
For example, viewController A and viewController B can both push viewController C into the navigation stack and ask C to do some saving (actually means the same to C).
in the saving method of C, the last line of code is
[self.navigationController popViewControllerAnimated:YES];
But problem is,
If I push to C from A, after I save something and pop back to A, things goes well.
But if I push C to from B, after I do the same thing and pop back to B, app crashes,
with my debugging, I found that app crashed not in C's code,
but after B's viewWillAppear method, here I mean after, B correctly runs all of the codes in viewWillAppear,
but then crashes somewhere I don't know how to trace to.
and the Error is very strange to me:

I just don't know how to fix it.
While dealing with number of viewControllers and views, it happens that frequent crashes occurs. I also had same problem when not using ARC. At that time i found the best way out is using following link to get into exact crash. The only thing is you need to carefully analyzed the result at console and should judge it better way...
