PushModalAsync() - Android L (5) RRS feed

  • Question

  • User3737 posted


    I've noticed one of our apps has stopped working for devices that have updated to Android 5 (Lollipop).

    I've narrowed it down to the Navigation.PushModalAsync() calls. The exception/Stack Trace I'm seeing is..

    No known package when getting value for resource number 0xff303030

    I've updated the nuget packages and the Android sdk tools, not sure what else to try.

    It happens for all modal navigation, but NOT non modal, i.e. Navigation.PushAsync() works as expected.

    Yes, I has the same error on Nexus 5 after upgrade to Android 5. I am using the latest stable Xamarin.Forms version ( Does Xamarin have a bug tracker?

    Just to update, I'm still seeing this issue on my Nexus 5 device, so it might just be specific to the device?

    I'm seeing this same behavior in a Lollipop emulator. Has anyone logged this on Bugzilla?

    I'm seeing this behavior as well. I'm searching bugzilla, but can't find it listed.

    Looks like a fix is on the way in the next pre-release of 1.3.
