After upgrading MvvmCross from version 4 to 5.1.1, I get the a TargetInvocationException at my entrypoint (UIApplication.Main(...)). This is the class:
using UIKit;
namespace sample
{
public class Application
{
// This is the main entry point of the application.
static void Main(string[] args)
{
// if you want to use a different Application Delegate class from "AppDelegate"
// you can specify it here.
UIApplication.Main(args, null, "AppDelegate");
}
}
}
And this is the exception that is thrown:
Unhandled Exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
The app has been terminated.
Failed to Stop app: An error occured on client IDB471022 while executing a reply for topic xvs/idb/4.7.10.22/stop-app
The app has been terminated.
The app works fine on mvvmcross 4, and the migration guide shows no surprises: https://www.mvvmcross.com/documentation/upgrading/upgrade-to-mvvmcross-50. I can't seem to debug anything. The only breakpoint that triggers is on UIApplication.Main, and step-into stops quite quickly and results in the given exception. Where do I start searching in order to fix this?
[edit]
This is still an issue, even with MVVMCross 5.7. It tries to instantiate a MainView class, which extends from MvxViewController. This happens before there is any code executed from my Setup class.
Looking at the line 26 that fails in MvxBindingViewControllerAdapter:
IosView.BindingContext = Mvx.Resolve<IMvxBindingContext>();
Where IosView is the ViewController cast to IMvxIosView. This suggests that your ViewController does not implement IMvxIosView. Since it seems like it is the only thing that would be null in this case.
I finally found the answer. I had 2 major versions of MvvmCross included in the project. I've now upgraded everything to 6.x.x. and the application starts up.

after last update our app start crashing randomly on some user devices . i can't get this crash on my ipad in release version, so may be it is device specific or ios version specific.
crash seems to be google ads related.

well, it turns out i am not the only one
https://github.com/xamarin/Xamarin.Forms/issues/11183
seems to be a bug in listview.
downgrade to Xamarin.Forms version 4.6.0.847 will solve this problem
I have ran into a weird problem with the AVPlayer. I am using the AVplayer to play videos downloaded in my application. The code below is how I setup the AVPlayer.
var filePath = new NSString("file://" + filePathOnDisk);
var fileUrl = new NSUrl(filePath);
_asset = AVAsset.FromUrl(fileUrl);
_playerItem = new AVPlayerItem(_asset);
_player = new AVPlayer(_playerItem);
_playerStateObserver = _player.AddObserver("status", NSKeyValueObservingOptions.New, PlayerReadyObserver);
_playerLayer = AVPlayerLayer.FromPlayer(_player);
_playerLayer.Frame = Frame;
Layer.AddSublayer(_playerLayer);
When I add an observer like in line 6 above the observer works fine and calls the Action I assigned to it. The problem is when I try to pause the AVPlayer. It causes a crash in the Mono runtime which cannot be caught with try/catch in C#.
I have confirmed that if I do not add the observer I can pause the AVPlayer without any crashes, but then I don't know how to listen for when the player is ready to play.
Adding an observer returns a IDisposable which I do have a reference too. If I dispose that variable before calling Pause then there is no crash. Can anyone please explain why this would be happening. Below is the crash log that I get when this crash occurs.
Any insight would be appreciated.
Thank you.

You skipped observer in your function call.
Instead of
_playerStateObserver = _player.AddObserver("status", NSKeyValueObservingOptions.New, PlayerReadyObserver);
Try
_playerStateObserver = _player.AddObserver(yourObserver, "status", NSKeyValueObservingOptions.New, nil);
On occassion, my Xamarin.iOS throws a SIGSEGV error when stopping audio.

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runt
Any help preventing this error from being thrown? I've tried putting the code that stops the audio into a try-catch but it still crashes the app.
I have an array of SystemSounds that when I exit the ViewController I want to stop playing all of the sounds. If a sound is currently playing then the code executes fine. It appears to throw the above error when one sound is completed and the next hasn't started. My code for stopping the audio is:
try
{
if (_tracks != null) // an array of tracks that have to be played
{
for (int i = _soundQueue - 1; i >= 0; i--) // _soundQueue is the num of tra
{
_tracks[i].Item1.RemoveSystemSoundCompletion();
_tracks[i].Item1.Close();
}
}
_soundQueue = 0;
_tracks = null;
_playingAudio = false;
}
catch (Exception ex)
{
}
I am trying to use the camera in a Xamarin iOS app.
First step seems to check if the app has access to the camera. But i get a fatal error in the mono runtime while doing this. Any idea?
Here are more details about the exception:
In Visual Studio (2015), I create a new "Blank App (iPhone)" project.
Since I own a iPhone 3GS, I switch to armv7 in the project properties, and select iOS 6.1 as deployment target.
Build app, debug on iPhone: the mac agent works well, and the empty app starts on my phone.
Then I go to AppDelegate.FinishedLaunching(...) and add
AVCaptureDevice.GetAuthorizationStatus(AVMediaType.Video);
before returning true.
Rebuild app, debug... and an exception is being thrown by GetAuthorizationStatus(...). Here is its stacktrace:

What is the version of iOS running on your device ?
select iOS 6.1 as deployment target.
Because if it's 6.1, like your deployment target, then you cannot call this API since it was added in iOS 7.0.
You need to conditionally call this on iOS 7.0+, e.g.
if (UIDevice.CurrentDevice.CheckSystemVersion (7,0)) {
AVCaptureDevice.GetAuthorizationStatus (AVMediaType.Video);
}
The assembly browser can show you, with attributes, the minimum version required for the API.
I'm trying to create a UIWebView and loading a page. When the loading finishes, I want to move to another screen.
The following code works on the iOS simulator, but not on a device.
I tried following this answer (Monotouch + UIWebView = Random Crashes), promoting the NSUrlRequest to become a global variable, but the error persists.
I tried using a try{} catch{} but it doesn't grab any exceptions when it crashes. it's driving me insane :)
void LoadSite(){
webView = new UIWebView (new CGRect (0, 0, 300,300));
string url = "http://google.com";
NSUrlRequest request = new NSUrlRequest(new NSUrl(url));
View.AddSubview (webView);
webView.LoadFinished+= (object sender, EventArgs e) => {
// CRASHES
};
webView.LoadRequest(request);
}
Any idea of how to solve this?
Thank you.
