Description

On Pixel 4 devices or newer with Android 12, if a file is opened using Launcher.OpenAsync() the file is opened in split screen mode adjacent to the source app regardless of whether android:resizeableActivity is false in the manifest file.

The issue is that when it goes into split screen mode the source app is reloaded and any in-progress state is lost in that app.

I've narrowed the problem down to the following logic in the PlatformOpenAsync() method of the Launcher.android.cs file:

#if __ANDROID_24__ if (Platform.HasApiLevelN) flags |= ActivityFlags.LaunchAdjacent; #endif

Removing this logic fixes the issue.

Steps to Reproduce

  1. Deploy your Xamarin App to a Pixel 4 or newer device
  2. Open a PDF or DOCX file from your Xamarin App using Launcher

Expected Behavior

PDF or DOCX file should be opened in a new window and the source app state should remain as before if android:resizeableActivity is false

Actual Behavior

PDF or DOCX file is open adjacent in split screen mode and the source app is reloaded, losing any in-progress state

Basic Information

  • Version with issue:
  • Nuget Packages: Xamarin.Forms 5.0.0.2012, Xamarin.Essentials 1.7.1
  • Affected Devices: Pixel 4a, Pixel 5

A side effect of that is that deep linking was working fine but now my app crashes when it is opened. On Android 12, the system tries to go with the adjacent option and since that flag is in the intent, the app is always launched in multi window mode and since my app doesn't support that well, it now crashes. When I use StartActivity, without the Launcher, and I don't use the adjacent flag, it works fine.

Does anyone have a workaround for this? Or do we build a local version of XE and apply changes @NavaJoey suggested ourselves?

The following worked for me inside the MainApplication

public override void StartActivity(Intent intent)
 {
    // Hack to prevent split screen issues, needs to happen here
    // as disabling in attributes causes app to crash
    if (Build.VERSION.SdkInt >= BuildVersionCodes.N)
    intent.RemoveFlags(ActivityFlags.LaunchAdjacent);

    base.StartActivity(intent);
}

I don't have a problem launching websites, but this happens when I try to use AppInfo.ShowSettingsUI(); and the above code doesn't help:

I'm seeing this issue occur when simply doing a ComposeEmail() call too.

Great that a fix seems on it's way.
When can I expect v 1.7.4 (with this fix included?) to be released?

Thanks for the fix! Any idea when this will be available? I saw 1.7.4 on the github release page, but it's not yet available on nuget it seems. @jfversluis
