Release build failed with "cannot find symbol android.app.KeyguardManager.DeviceLockedStateListener, android.service.chooser.ChooserSession.StateListener" errors

[Logan2014]

Android framework version

net10.0-android

Affected platform version

.NET Core sdk version: 10.0.102

Description

After migration from .Net 9 to .Net 10 (net10.0-android36.1) I got this issue both on my local machine with VS 2026 18.2.1 and with Azure DevOps pipeline, trying to get release of my app.

Steps to Reproduce

Run release build for net10.0-android36.1 target

Did you find any workaround?

I tryed to turn off linker with <PublishTrimmed>False</PublishTrimmed> or <TrimMode>None</TrimMode> inside project file but this did not help me.

There is suggestion to "Recompile with -Xlint:deprecation for details." or "Recompile with -Xlint:unchecked for details." but I can't control java compilator parameters through .Net project settings.

Can you share a .binlog or a sample project with this error? https://aka.ms/binlog

Here is binlog file.

So, the problem is:

JavaPlatformJarPath = C:\Program Files %28x86%29\Android\android-sdk\platforms\android-36\android.jar

Where this needs to be using:

• C:\Program Files %28x86%29\Android\android-sdk\platforms\android-36.1\android.jar

This looks like it would happen if you made a C# class implement/extend DeviceLockedStateListener.

I don't use such class directly or through any NuGet package. I'll tryout next .Net Core release with this fix to prevent fallback to major version...
