We'd like to use the new AndroidX support for BiometricPrompt (so we don't need to provide a custom UI on devices < Android.P) , but I don't see the equivalent listed in the preview packages available for Android X.

I think you're focusing on the port of existing support libraries first, but this one is brand new and did not have a support library package.

I think this is a known issue on the Google side, but I'm not sure if it has been sorted yet or is going to propagate to Xamarin soon:

Stack overflow issue

I have a SupportMapFragment, which inherits Support.V4.App.Fragment. Before I migrated to AndroidX I had this line:

_mapFragment = (SupportMapFragment)ChildFragmentManager.FindFragmentById(Resource.Id.map);

Now I get a casting error because the AndroidX fragment's child fragment manager doesn't return a support fragment.

After applying the suggested fix from #56 and rebuilding the library I'm running in to some sort of incompatibility with Material Visual on Android with Entry and Editor.

With the new version, on Android, the background color of Entry seems to come from TextColor instead of BackgroundColor, with BackgroundColor having no effect. From what I'm personally using in the library, this seems to be the only issue. These fields display as expected on iOS.

I don't know if this is the proper place to report this, so if I'm incorrect just let me know.

Below is what I'm seeing, Android:

Steps to Reproduce (with link to sample solution if possible):

App29.zip

I have seen that vs now supports migration tooling as an experimental feature that we have to turn on.

After turning on that feature I cannot find any way to use migration wizard. I am completely failed to find any doc about it. Then I learned from a twitter screenshot that option for migration will be appeared in my projects menu(under archive in build menu). But in my case I cannot find anything.

What am I missing ?

Anyone could how to build it since https://dev.azure.com/xamarin/public/_apis/build/builds/10297/artifacts?artifactName=nuget&format=zip&api-version=5.0 return 404

@mattleibow

• Migration Package: Copy mappings into github for source / nice completeness
• Migration Package - Update version
• Migration package - Check that warnings for installing nugets show correct version
• Migration package - Check that all assemblies added to .props

@moljac

• Create new FWLink for ProjectLink
• Add Cake logic to check all <attr> nodes with interface in the path attribute do not have name="visibility" attributes (or throw error)
• Fix Material version (the artifact is 1.0.0 yet the nuget is 1.1.0x) NOT ONLY Material
• Bump to -rc1 nuget version
• Add cake logic to check that the artifact version matches the nuget version prefix

I dont undestand where is the problem in migration process to AndroidX.

I've just tried to uninstall all Xamarin.Firebase.* and Xamarin.GooglePlayServices.* packages , then readded but problem persists..

Thanks for any suggestions.
Best Regards.

Support Libraries Version (eg: 23.3.0):

Xamarin.AndroidX.ViewPager2 1.0.0

Describe your Issue:

The class FragmentStateAdapter which is used for the new ViewPager2 seems to have a Java binding issue regarding inheritance.

In Java, the FragmentStateAdapter class inherits the RecyclerView.Adapter class, which has the abstract onBindViewHolder method. This abstract method is implemented and sealed (marked final) by the FragmentStateAdapter class to get a chunk of its functionality working. In Java and Kotlin this means any implementation of FragmentStateAdapter does not require implementation of the onBindViewHolder method.

In the Xamarin binding there seems to be a mismatch in inheritance however. The signature of the of the OnBindViewHolder implementation in FragmentStateAdapter seems to mismatch with the OnBindViewHolder in the parent RecyclerView.Adapter class.

On the C# side of things, this causes the responsibility of implementing the abstract OnBindViewHolder in RecyclerView.Adapter to cascade down to the classes that inherit FragmentStateAdapter (since the implementation in FragmentStateAdapter mismatches it is now missing as far as the C# compiler is concerned)

If I try to implement the method in my FragmentStateAdapter subclasses to make sure the C# compiler shows no errors, the Java build error shown below appears instead:

JAVAC0000:  error: name clash: onBindViewHolder(ViewHolder,int) in MyTestActivity_MyPagerAdapter and onBindViewHolder(VH,int) in Adapter have the same erasure, yet neither overrides the other
	public void onBindViewHolder (androidx.recyclerview.widget.RecyclerView.ViewHolder p0, int p1)  where VH is a type-variable: VH extends ViewHolder declared in class Adapter

Possible cause

The issue seems to be caused by the following mismatch:

In Java, the generic signature onBindViewHolder(VH holder, int position) (where VH is a generic defined in the RecyclerView.Adapter class signature) is properly inherited by the method signature onBindViewHolder(FragmentViewHolder holder, int position).

In C#/Xamarin however, it seems the RecyclerView.Adapter doesn't have this generic aspect bound. Instead using the ViewHolder base type in place of the generic.
This likely causes the OnBindViewHolder(FragmentViewHolder holder, int position) method in the FragmentStateAdapter to mismatch with the now non-generic OnBindViewHolder(ViewHolder holder, int position) method in the RecyclerView.Adapter class

I'm not being able to compile my project on release mode anymore without "Use Shared Runtime" checked.

Hello there,

It seems that the [Lifecycle.Event.OnStart], [Lifecycle.Event.OnStop] and other from the AndroidX.Lifecycle namespace have their java annotation counterparts set to the old libraries.

Found this while testing the migration in the Toggl app, we are using the old [Lifecycle.Event.OnStart], [Lifecycle.Event.OnStop] here:
https://github.com/toggl/mobileapp/blob/d79af0ab5522a325046baf19b4616cb086b1bc71/Toggl.Droid/Startup/TogglApplication.cs#L83-L99

Test branch: https://github.com/toggl/mobileapp/tree/doivid/androidx-migration-test

After migrating, we get this error while building:

TogglApplication.java(34, 25):  error: package android.arch.lifecycle does not exist

Have to revert back to preview06. See Class PreferenceManager

During my testing I broke the symbols. As a result, the build could never succeed as it will read the broken symbols and crash.

If there is a NuGet out there that has bad symbols...

Xamarin Android Version: 10.1.3.7

Operating System & Version: Mac OS 10.14.6

Support Libraries Version: 28.0.0.1

Describe your Issue:

I have a project with transitive dependencies which reference the Xamarin.Android.Support.Media.Compat package, and some which reference the newer Xamarin.AndroidX.Media package.

I have installed the Xamarin.AndroidX.Migration package.

When I attempt to reference the type MediaSessionCompat, I recieve the following error message:

Error CS0433: The type 'MediaSessionCompat' exists in both 'Xamarin.Android.Support.Media.Compat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' and 'Xamarin.AndroidX.Media, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' (CS0433)

I'm not sure if this scenario is supposed to be handled by the tooling, or if there is some other change I should have made to the project as part of the migration.

Many thanks for your help.

After following the directions and installing the necessary nugets I was told to install, we still cannot compile. We get a ton of errors for "Original attribute defined here."

Any suggestions? The errors do not say where they are being spawned from. They started coming up about the same time we added the AndroidX.AppCompat nuget.

Any help would be appreciated.

Picked up the new 4.5.0-pre2, fixed one missing reference to AndroidX.MediaRouter, and our app built.

Comparing the old vs new build (which uses aot startup profiling):

• Looking at the apk assemblies folder, I can see that the Android.Support dlls are gone, replaced by a list of AndroidX dlls.
• Looking into the lib folders, I see libaot files for both Android.Support and AndroidX. The number of android.support files is the same as before, but some of them are now smaller in size (all around 7KB).

Is this in any way expected or possibly reflecting an issue?

I couldn't compile my project using Dotfuscator:

Setting the DotfuscatorXamarinEnabled option to FALSE in my csproj solves the problem.

Example: Xamarin-AndroidX.Preference 1.0.0-preview06

Describe your Issue:

It seems that since preview03 of the AndroidX libraries some methods previously bound to a explicit return type now only return Java.Lang.Object.

For example, since 1.0.0-preview03 the method public <T extends Preference> findPreference (CharSequence key) (and its overloads) in PreferenceFragmentCompat, which was previously bound with a Preference return type, is now bound with a Java.Lang.Object return type.

While casting this Object to a Preference does work fine, it does add a extra layer of casting not originally present.

The issue seems to be related to the method return types being a implicit generic <T extends Preference> rather than the explicit return types these methods used to have in the pre-AndroidX support libraries.
Though the return type is defined as generic, a subclass of Preference is guaranteed through the extends Preference condition, so abstraction as far as Java.Lang.Object should not be necessary.

There appears to be 2 files under obj\Debug\XX\proguard:

• proguard_xamarin.cfg
• proguard_project_primary.cfg

These files are not part of the normal @(ProguardConfiguration) configuration group, so I believe are being missed. They contain all the bits that Xamarin.Android needs to run, so can't be removed at all.

Noticeable in https://github.com/toggl/mobileapp

The type Android.Support.V4.Media.Session.MediaSessionCompat.IOnActiveChangeListenerImplementor is in both Xamarin.AndroidX.Media.dll and Xamarin.Android.Support.Media.Compat.dll.

Among other problems this causes the Android designer to bark at the situation and disable custom controls rendering.

Since the type is autogenerated by Xamarin.Android there is likely a corner case somewhere.

Description

After installing Xamarin.Forms 4.5.0.356 and updating all AndroidX packages the rebuild process produces the following error:

../Test/packages/Xamarin.AndroidX.Migration.1.0.0/build/monoandroid90/Xamarin.AndroidX.Migration.targets(9,9): Error: Could not find 1 Android X assemblies, make sure to install the following NuGet packages:

Workaround

No workaround was found. :(

Is there a way to enable FontAwesome Icons in AndroidX? They work fine when I roll back to Android 9.

I have them setup in my Resource.Dictionary in App.xaml and then refer to the ImageSource as a {StaticResource FontImageName}.

Any ideas?

After upgrading to the preview03 versions of the support packages builds started failing for my Xamarin Forms Android project with the following error message:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2105,5): error MSB4018: The "LinkAssemblies" task failed unexpectedly. 
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2105,5): error MSB4018: Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could not resolve reference to 'AndroidX.AppCompat.Graphics.Drawable.DrawableWrapper' (defined in assembly 'Xamarin.Forms.Platform.Android, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null') with scope 'Xamarin.AndroidX.AppCompat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. When the scope is different from the defining assembly, it usually means that the type is forwarded. ---> Mono.Cecil.ResolutionException: Failed to resolve AndroidX.AppCompat.Graphics.Drawable.DrawableWrapper

The linker seems to be looking for the DrawableWrapper definition in the Xamarin.AndroidX.AppCompat assembly, which is where it was defined prior to the preview03 release of the support package. It seems this type along with a few others were moved into a new Android library, androidx.appcompat.appcompat-resources, so they are now located in a new assembly for the Xamarin Android support packages, Xamarin.AndroidX.AppCompat.Resources.

I was able to get the build working by adding a _AndroidXAssembly definition for Xamarin.Android.AppCompat.Resources in Xamarin.AndroidX.Migration.props, and also updating the AndroidX .NET Assembly column values to Xamarin.AndroidX.AppCompat.Resources in androidx-mapping.csv for the types:

AndroidX.AppCompat.Graphics.Drawable.AnimatedStateListDrawableCompat
AndroidX.AppCompat.Graphics.Drawable.DrawableWrapper
AndroidX.AppCompat.Content.Res.AppCompatResources
AndroidX.AppCompat.Widget.DrawableUtils
AndroidX.AppCompat.Widget.TintContextWrapper
AndroidX.AppCompat.Widget.VectorEnabledTintResources

The list of Android Support and Android X assemblies need to be updated in the Xamarin.AndroidX.Migration.props.

These lists are simply to help the build skip out the assemblies we KNOW are already migrated - Android X is already Android X, or that should NOT be migrated - Android Support is never going to reach the device.

There is also a list of Android X artifacts that we know should not even be opened.

All of this is to speed up the build. Since the types are already Android X, they should never need updating and will be skipped. But 70+ dlls and 70+ jars does mean that it takes a good few milliseconds more than necessary.

Make sure all projects with a .targets and/or .props file also use the buildTransitive folder.

Steps to Reproduce (with link to sample solution if possible):

Include any relevant Exception Stack traces, build logs, adb logs:

We have some really old things, such as components

after migrating it is the designer doesn't render controls from Android Support Library, instead youre asked to perform a nuget restore which does nothing. please fix this soon.

Copy of this issue: xamarin/AndroidSupportComponents#225

Support Libraries Version (eg: 23.3.0):

Xamarin.Android.Support.Constraint.Layout 2.0.0-beta2
Xamarin.Android.Support.Constraint.Layout.Solver 2.0.0-beta2

Describe your Issue:

The interface ITransitionListner just has p0, p1, p2, p3 as names for the arguments you can pass into the method it defines.

void OnTransitionChange(MotionLayout p0, int p1, int p2, float p3)
void OnTransitionCompleted(MotionLayout p0, int p1)
void OnTransitionStarted(MotionLayout p0, int p1, int p2)
void OnTransitionTrigger(MotionLayout p0, int p1, bool p2, float p3)

I would expect them to be:

void OnTransitionChange(MotionLayout motionLayout, int startId, int endId, float progress) 
void OnTransitionCompleted(MotionLayout motionLayout, int currentId) 
void OnTransitionStarted(MotionLayout motionLayout, int startId, int endId) 
void OnTransitionTrigger(MotionLayout motionLayout, int triggerId, bool positive, float progress) 

See: https://developer.android.com/reference/androidx/constraintlayout/motion/widget/MotionLayout.TransitionListener

Steps to Reproduce (with link to sample solution if possible):

1. Add Xamarin.Android.Support.Constraint.Layout 2.0.0-beta2
2. Implement MotionLayout.ITransitionListener: private class MotionLayoutListener : Java.Lang.Object, MotionLayout.ITransitionListener
3. Ask VS to implement methods

Any chance to update Xamarin.AndroidX.Biometrics? The latest version 1.0.1 contains a lot of important bugfixes! I thought after switching to AndroidX we would get the latest bindings more regularly, but apparently that doesn't seem to be the case (yet?)

I attached a debugger and disassembled the method.

And the method has this Implementation.

public ISymbolWriter GetSymbolWriter(ModuleDefinition module, Stream symbolStream)
    {
      throw new NotImplementedException();
    }		

So it isn't implemented.

Describe your Issue:

When a Xamarin.Forms component has a dependency on Android.Support.v7.RecyclerView, the AndroidX RecyclerView type is used by accident when the project's Linker is set to SDK Assemblies Only

This results in an a build error claiming the setHasStableIds method cannot be resolved.

Steps to Reproduce (with link to sample solution if possible):

Setup

1. Download the reproducible project from here (all assembly references and NuGet packages are installed).
2. Make sure project in Release configuration and the Android project is set as Startup

Run 1 - Control Test

1. Set LinkerBehavior to None
2. Rebuild Solution (to restore NuGet packages and complete 1st build)
3. => Observe a successful build

Run 2 - Reproducible Test

1. Set LinkerBehavior to SDK Assemblies Only
2. Clean project and Rebuild
3. => Observe the error listed below.

Include any relevant Exception Stack traces, build logs, adb logs:

Error Mono.Linker.MarkException: Error processing method: 'System.Void Telerik.XamarinForms.DataControlsRenderer.Android.ItemsControlRenderer::OnElementAttached(Telerik.XamarinForms.DataControls.ItemsControl)' in assembly: 'Telerik.XamarinForms.DataControls.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void AndroidX.RecyclerView.Widget.RecyclerView/Adapter::set_HasStableIds(System.Boolean)

Telerik Code

The location that error is thrown in in our adapter class. I am unable to share the full source code, but I can still identify how we're expecting the type to be android.support.v7.widget.RecyclerView

Notice the following:

1. The class imports android.support.v7.widget.RecyclerView
2. The CTOR is expecting setHasStableIds() to be available in the SDK's RecyclerView Adapter

import android.support.v7.widget.RecyclerView;
...

public abstract class ListViewAdapterBase extends RecyclerView.Adapter<ListViewHolder> {
    ...
    public ListViewAdapterBase() {
        [dedacted]
        [dedacted]
        [dedacted]
        this.setHasStableIds(true);
    }
    ...
}

Workaround Attempt

I tried to avoid this by telling the compiler to linkskip Xamarin.Android.Support.v7.RecyclerView. However, it doesn't work. Is there another assembly I can add to workaround the issue?

the only solution I could find was to uninstall Xamarin.AndroidX.RecyclerView. Once it (and dependencies) were uninstalled, the build works when linking out SDK Assemblies.

As described in issue #19, the originally explicit Preference return values for the "findPreference" methods were bound as Java.Lang.Object since preview03. A fix was made to the transform metadata in commit 7a839db but release 1.1.0-rc1 following this fix still has the generic return type binding. As requested in the original issue I have opened a new issue on this.

Excerpt from PreferenceFragmentCompat object metadata:

public Java.Lang.Object FindPreference(string key);

W/BiometricPromptCompat( 5060): Not launching prompt. authenticate() called after onSaveInstanceState()

Calling the Biometric Prompt during OnResume() dismisses the dialog with an error saying that the prompt cannot be launched after onSaveInstanceState() has been called.

Wrapping the call to BiometricManager in a fragment transaction with CommitAllowingStateLoss() also does not have any effect

Steps to Reproduce (with link to sample solution if possible):

Calling the Biometric Prompt during OnResume()

        {
            var promptInfo = new BiometricPrompt.PromptInfo.Builder()

                .SetNegativeButtonText("Cancel")
                .Build();

            var activity = _activityResolver();
            var executor = Executors.NewSingleThreadExecutor();
            var handler = new BiometricsAuthenticationHandler();
