[android] add AOT profile for .NET MAUI (#2496)

jonathanpeppers · web-flow · commit 7dcc01a35c0d · 2021-09-17T08:34:55.000-05:00
Context: dotnet/android@3e699d6 Context: https://github.com/jonathanpeppers/android-profiled-aot Add a `maui.aotprofile`, and bundle with .NET MAUI. Recording custom profiles is not supported by dotnet/runtime, but it can be done following the instructions in the jonathanpeppers/android-profiled-aot repo. To ship an AOT Profile for MAUI: 1. Default `$(AndroidUseDefaultAotProfile)` to `false`, so the plain Android profile is not used. The default Android profile only contains methods in AndroidX, Mono.Android.dll, Java.Interop.dll, etc. 2. Default `@(AndroidAotProfile)` to `maui.aotprofile`, unless `$(MauiUseDefaultAotProfile)` is `false`. ~~ Profile Contents ~~ Modules: EA3844FC-D728-4D48-9598-1C93505E4623 System.Private.CoreLib 2CC403AF-60DC-48A9-9B69-FF254277AEA0 Mono.Android 92FF7068-2EA9-4681-B340-44E91077417A Java.Interop 3E65EB5C-02E9-4DE5-AC19-B2F2BAF2857B Microsoft.Maui.Essentials 21CF52B7-0256-4838-848C-DA026B2F1789 Xamarin.AndroidX.Core 35358E14-E381-4472-858E-ABFD81B3517C Microsoft.Maui 5A334DAA-789C-421E-9B20-F1B66879BF49 Microsoft.Extensions.Hosting C3C04DA6-9F0C-48FD-83EA-115CB6076248 Microsoft.Extensions.DependencyInjection 1CC454CF-BE07-4D95-B1E7-3EFC458F943C Microsoft.Extensions.DependencyInjection.Abstractions 229E3EBA-F00D-40DF-BEB8-4C16CB84DE98 Microsoft.Extensions.Configuration.Abstractions CCAA9BA7-D5D3-47EC-8FBB-DED7D6FC2143 Microsoft.Extensions.Configuration 981BD5D2-69A5-4C0B-A258-50BB28365D5B Microsoft.Extensions.Primitives C674A867-6352-482C-9A7A-0272480711AC Microsoft.Extensions.Hosting.Abstractions 1D537869-4CC1-4E6D-B0BF-6ABEA40ADF8B Microsoft.Extensions.Configuration.FileExtensions 3C68719B-EA9F-48EC-86D7-2EE85CDA2272 Microsoft.Extensions.FileProviders.Physical 0D1C05F9-FFB8-4A75-A24E-6C17893B53F7 System.Linq DCE2ADDD-008E-43B4-B1D6-3CCA222678FF Microsoft.Extensions.Logging C9E0059C-3CE2-4B91-BE1D-808EF93495C3 Microsoft.Extensions.Options 8A3A36B0-0D51-4CF6-A5F0-2E1EF0A01648 Microsoft.Extensions.Logging.Abstractions DDC70C0B-3BAA-4844-8401-65EA77FBDDDC Microsoft.Extensions.Logging.Configuration 28AB2955-BA00-4EAC-90B6-4E31F4826D75 Microsoft.Extensions.Options.ConfigurationExtensions BC607A7F-080C-424F-8A37-011B30F6DE55 Microsoft.Extensions.Logging.Console 1BDE760B-6269-47BC-9BF5-6B44DC9CC032 Microsoft.Extensions.Logging.Debug 9D7AA4B2-70B7-4329-A099-BE5F3B8FE0A4 Microsoft.Extensions.Logging.EventSource DF5F5616-FA06-46C0-8025-6DA20BB34CEC Microsoft.Maui.Controls.Compatibility 63B89754-AAED-4092-9FDE-E50EB969DE1B MauiApp1 1F1E6C61-F9BC-488D-9EC4-335D0D5A0800 Microsoft.Maui.Graphics 38104510-26A0-4B40-8542-80153806B860 System.Diagnostics.DiagnosticSource F7E05AD1-4195-4539-B3AD-487030D94748 System.Collections.Concurrent 2795C489-C1E7-40BC-ACF2-B84C11F67B47 Microsoft.Extensions.Configuration.Binder F26C0583-5BFE-4B78-BC65-84547BAA9F75 System.Runtime.InteropServices.RuntimeInformation 404F6169-7356-4D95-BD9A-3A5C7D88BD6E System.Console CD148B87-3553-48A2-8853-CEC72437F2A2 Microsoft.Maui.Controls 99F9B89D-EF4E-4F6B-B785-56AFD6E37113 Microsoft.Maui.Controls.Xaml 1B55562C-5DD7-4779-8473-8B4558C8D065 System.ComponentModel.TypeConverter 43402C13-3212-4B9C-8A1C-0BA8C6AC6F29 System.ObjectModel 8766384A-BB06-42DA-810C-B5B2B0D7C971 System.Private.Xml 82E0E2F3-002E-4780-BEC2-E230299A5ED2 System.Private.Uri 7CEE6098-BE9F-4043-B35A-B8B0684EF0CB Xamarin.AndroidX.AppCompat 20D1FBB8-829A-4618-8E82-8047C8827EA8 Xamarin.AndroidX.Fragment CC363D7A-9CDB-4999-9E10-279412B14A1B Xamarin.AndroidX.Activity 008C0F24-5014-4D41-AAB9-DDFCEA59E171 Xamarin.Google.Android.Material Summary: Modules: 42 Types: 1,234 Methods: 5,030 ~~ Results ~~ All tests: 1.
