Xamarin cycle 8 compatibility issues #56

Closed NaurisAndzans closed 8 years ago

NaurisAndzans commented 8 years ago

Yesterday I followed the release of the new and stable version of Xamarin and its components just to find that rb-forms-barcode is not longer working. So I dowloaded the sample project to see if the same problems occurs running clean sample and the problem does occur.

The problem persists every time.

As soon as I try to open the scanner page app crashes with the following message: " Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries. "

Has anyone else experienced such behaviour after following the upgrade to cycle 8?

Hello @NaurisAndzans

I am as well on cycle 8 and everything is working on ios and android for me. Can you clean and build the project completly new please.

What are you doing. I need more infos to help you in this case.

Is it everytime crashing, or only one time?

NaurisAndzans commented 8 years ago

I forgot to add that I'm working on a Macbook and I encounter this problem only with iOS builds. Android builds works as expected.

As soon as the following line gets called the app crashes with the message I posted previously. Detail.Navigation.PushAndRemovePrevious(ScannerPageControl.Instance.CreateScannerPage(), 1);

and you think that happens due to the scannerlibrary?

armintelker commented 8 years ago

can you please create a sample github project that contains the bug.

NaurisAndzans commented 8 years ago

can you please create a sample github project that contains the bug.

No need, cause I used your original sample without introducing any new features for testing this behaviour. Any other information or additional logs I can provide you with ?

I am also experiencing the same issue. Everything was working fine before iOS10. Now, as soon as the page opens and gets past the default constructor, it crashes. I am only testing with iOS and have not yet implemented for Android.

I also just downloaded the sample and ran it without changing a thing. It opens, but then when I click on SCAN ALL THINGS, it crashes:

I appears to be crashing in RootPage.xaml.cs line 21: await cameraPermission.RequestCameraPermissionIfNeeded();

I am wondering if there is some new plist setting we need?

jmockjm commented 8 years ago

Yep, just figured out the solution.

@NaurisAndzans add this to your info.plist:

Property: "Privacy - Camera Usage Description" Value: "Use the camera for XYZ"
