Speakerphone not responding on Android 11 but responding on Android 10

Question

Speakerphone not responding on Android 11 but responding on Android 10

Universal Camera 276

If I deploy this on my Android 10 phone then speakerphone is activated during a phone call

AudioManager am = (AudioManager)Android.App.Application.Context.GetSystemService(Context.AudioService);
am.Mode = Mode.InCall;
am.SpeakerphoneOn = true;

however same code does not produce same results on Android 11 phone (Speakerphone is not activated)

I have a Cross-Platform App using VS2019 Community Version 16.9.1

Thank you

My code execute on both devices without any problem but on Android 11 it does not turn on the speakerphone. The same code turn on speakerphone on Android 10 phone. The code does not crash or generate any problems on both.

So I cannot use my app on Android 11 phone.

Thank you

   protected override void OnCreate(Bundle savedInstanceState)

        base.OnCreate(savedInstanceState);

        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
        LoadApplication(new App());
        phoneDialer =  CrossMessaging.Current.PhoneDialer;
        RunOnUiThread(async () => { await Task.Delay(10000); CallPhoneNumber("1234567890"); });
    }

    IPhoneCallTask phoneDialer;
    AudioManager audioManager;

   void CallPhoneNumber(string PhoneNumber)
    {
        if (phoneDialer.CanMakePhoneCall) { phoneDialer.MakePhoneCall(PhoneNumber); }
        Task.Delay(5000).Wait();
        audioManager = (AudioManager)Android.App.Application.Context.GetSystemService(Context.AudioService);
        audioManager.Mode = Mode.InCall;
        audioManager.SpeakerphoneOn = true;
    }

Hi @Universal Camera , what's the IPhoneCallTask in your code? Have you installed other nuget?

Thank you

That is linked to Xam.Plugin.Messaging reference which I added through GIT. Of course you have to add appropriate permissions

Hi @Universal Camera , if we check link Xam.Plugins.Messaging ,we will find that nuget Xam.Plugins.Messaging hasn't been updated for a long time. So we don't recommend you to use Xam.Plugins.Messaging. You can use Xamarin.Essentials instead, which includes the features you need above. You can check it here: Xamarin.Essentials: Phone Dialer , Xamarin.Essentials: SMS and Xamarin.Essentials: Email .

Thank you

Since Xamarin.Essential does not have auto dialer I windup re-writing the code based on SendAndRecieveSMS sample using DependancyServices.

The results are the same. Speakerphone is activated in Android 10 but not on Android 11. Its not about how you are making a call it all about how to turn on the speakerphone using AudiManager.

What other ways you can turn on Speakerphone that will work on Android 11 during a call??????

Thank you

Based on your recommendation I created a simple example that turns on SpeakerPhone on Android 10 but fails to turn on SpeakePhone on Android 11 during a phone call. I wonder if there has to be additional "Something" that needs to be done on Android 11.

    public void PlacePhoneCall(string number)
    {
        PhoneDialer.Open(number);
        Task.Delay(10000).Wait();
        am = (AudioManager)Android.App.Application.Context.GetSystemService(Context.AudioService);
        am.Mode = Mode.InCall;
        am.SpeakerphoneOn = true;
    }
    protected override void OnCreate(Bundle savedInstanceState)
    {
        ....

        RunOnUiThread(async () => { await Task.Delay(10000); PlacePhoneCall("0123456789"); });
    }

Thank you!
