(Candidate fixes for many of these remaining issues are now available on the Alpha updater channel.)
Non-public Bug 28995 - [Android] On certain devices, certain apps crash frequently due to "System.ExecutionEngineException: SIGILL". Now fixed in the Beta and Alpha channels.
Bug 30318 - [Android] Windows only: Breakpoints in PCL projects do not work after cleaning solution, redeploying, and restarting debugging. Now fixed in the Beta and Alpha channels. (Old partial workaround: delete all the
bin folders in the solution after cleaning.)
Bug 30371 - [XamarinVS] [Android] Project Properties display incorrect default values for "BundleAssemblies" and "EmbedAssembliesIntoApk" if they are not explicitly specified. This means that these properties can "automatically" change to incorrect values when you update other properties under "Project Properties -> Android Options". The incorrect values can cause secondary symptoms like Bug 30334 where breakpoints are not hit in the Debug configuration. Now fixed in the Beta and Alpha channels.
Non-public Bug 30057 - [Android] Windows only: the debugger will not be able resolve breakpoints unless "Shared Runtime" is ON and the Linker is OFF (under "Project Properties -> Android Options" in Visual Studio or "Project Options -> Android Build" in Xamarin Studio). Now fixed in the Beta and Alpha channels.
Bug 29326 - [Android] String resources defined in NuGet packages overwrite string resources defined in app project, causing the displayed app name to be incorrect for example. Workaround: avoid using the same string key that is used in the NuGet packages.
Non-public Bug 30481, Bug 29557 - [Mono] [Android] [iOS]
SqlConnection.GetSchema() fails with "SourceTable is required to be a non-empty string".
Bug 30548 - [Android] Under certain conditions new threads take several seconds to start. This problem seems to be triggered by Xamarin.Insights 1.10. Partial workarounds: upgrade Xamarin.Insights to version 1.10.3, downgrade it to version 1.9, or remove it entirely.
Bug 30072 - [Xamarin Studio] [Android] Xamarin Studio sometimes crashes with SIGABRT in
gtk_text_view_validate_onscreen() after password is entered during "Import an Existing Key" in "Build -> Archive for Publishing -> Sign and Distribute" workflow. Now fixed in the Beta and Alpha channels.
Non-public Bug 29538 - [Android] Profiling via the graphical Xamarin Profiler ("Run -> Start Profiling") causes the app to crash at startup. Now fixed in the Beta and Alpha channels.
Bug 30915 - [Xamarin Studio] [Android] Xamarin Studio repeatedly asks for the password for the selected certificate when attempting to sign using
SHA1withDSA certificates from keystore files. Xamarin Studio should instead display the error message from
jarsigner: "private key algorithm is not compatible with signature algorithm" as it did in Xamarin Studio 5.8. (
MD5withRSA certificates do work without error.)
Bug 29731 - [Android]
Android.Bluetooth.BluetoothAdapter.Enable is incorrectly marked as
[Obsolete("deprecated")] for API level 20 and higher.
Non-public Bug 29725 - [Xamarin Studio] [iOS] [Android] Expressions in the Watch window are cleared each time you stop debugging. Now fixed in the Beta and Alpha channels.
