Email.ComposeAsync behaves incorrectly on the Pixel 6.

oiqbal 1

On other Android devices that we tested, the email function provided by Xamarin.Essentials worked as intended. The app opened the email app with the provided subject, recipient, and body fields filled out. On the Pixel 6 (Android version 12) we ran into an issue where instead of opening up the email app as a fullscreen application, it instead opened it up in a multi-window view.

The main issue is that the Android's MainActivity's OnCreate gets called when this happens and restarts the app as if it was booted for the first time (The MainActivity's LaunchMode is set to LaunchMode.SingleTask). In the AndroidManifest, I can disable multi-window mode by using android:resizeableActivity="false." This gets rid of the multi-window issue and also the issue of the app restarting. However, now the issue is the email app gets loaded in the background instead of automatically sending the user to the email app. The user has to manually switch over to the email app to get to it. Both of these situations are not ideal so we are asking here in hopes of a fix or workaround.

This is indeed a strange issue. Would the issue occur in other Android Devices or Emulators?

You can try Launcher to send emails in the following way:

uri = $"mailto:{address}?subject={emailSubject}&body={body content}"; Launcher.OpenAsync(uri);

Will this help you?

This issue only occurs on the Pixel 6 from what I can tell. We have two Pixel 6's and it occurs on both. We tested this on a real Pixel 3, an emulated Pixel 3, and an emulated Nexus One (running Android 12). The email function works correctly on those.

I tried your suggestion, but the situation remains unchanged on the Pixel 6. I tried it with and without the android:resizeableActivity line in the AndroidManifest and same issues I described in my original post are still occurring.

As you said, the problem only happens in Pixel 6.

It should be an issue with Pixel 6, you could turn to Pixel Phone Help to create a new thread for fixing this issue.
