Android soft keyboard opens on app start #13471

Open Adam-- opened 10 months ago

Adam-- commented 10 months ago

Describe the bug

Soft keyboard opens on app start on Android on our customized Android device.

To Reproduce

Steps to reproduce the behavior:

  1. Create a new app from the Avalonia template.
  2. Deploy to our device, a custom ARM based Android board running a customized kiosk style Android 7.1 OS without a navigation or status bar.
  3. Notice the soft keyboard opens. Pressing enter doesn't close the keyboard.

I am unable to reproduce on an emulator or other physical devices.

Expected behavior

The soft keyboard doesn't open on app start.

A custom android setup? How should we debug it? Best bet is, you clone the source and debug it in src/samples/Sandbox on your special device. Maybe you find the root cause there.

A custom android setup? How should we debug it?

@timunie, I'd imagine there'd be some back and forth or some diagnostics logs that I could gather.

Best bet is, you clone the source and debug it in src/samples/Sandbox

I started there; however, when I build I get >1500 errors. Most of these errors seem to be related to types and namespaces not being found for XamlX, IXamlType, etc. I have the same issue in Visual Studio and Rider with Avalonia extension. I looked through the documentation and found no help for building the source there. Did I miss it? Is there something in particular I need install?

Have you see this?

That's exactly what I was looking for, thanks!

Adam-- commented 10 months ago

Thanks again for linking the guide, I was able to follow along and I believe I have everything setup correctly. I don't get any issues building the core projects nor the wpf projects; however, when I attempt to build the MobileSandbox.Android project it gets stuck at:

12:22:19:777    1>Target "_GetPrimaryCpuAbi" in file "C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.95\tools\Xamarin.Android.Common.Debugging.targets":
12:22:19:777    1>  Task "GetPrimaryCpuAbi"

This never finishes and I have to cancel the build.

It's a similar experience in Rider.

It seems though that we are straying away from the original issue I had with the keyboard, would you like me to open another issue for this or is it okay to keep discussing here?

Check android workload is installed dotnet workload list

you should have a list like this:

Is there anything in particular that I'm looking for?

Adam-- commented 10 months ago

@workgroupengineering, I git clean -fxded and restarted my computer and I'm able to build and deploy the Sandbox and ControlCatalog Android projects now. Not sure why this fixed it. Thanks again for all your help!

Adam-- commented 10 months ago

I've stepped through the startup and I haven't been able to figure out why the keyboard is showing, but figured I'd share what I saw.

It doesn't seem that any of the code related to showing the Android keyboard in AndroidInputMethod is being called. SoftKeyboardListener does see that the keyboard is being opened.

Interestingly if I comment out the_host.FocusableInTouchMode = true in the AndroidInputMethod constructor and then set it after startup (very silly Task.Delay(10000).ContinueWith(task => _host.FocusableInTouchMode = true); in place of the _host.FocusableInTouchMode = true), the keyboard doesn't erroneously pop up and (after 10 seconds) works as expected. It's obviously not a solution to the problem, just an interesting observation. Also if I attempt to set FocusableInTouchMode = true in AvaloniaMainActivity InitializeApp or MainActivity OnCreate, they keyboard doesn't pop up even when it should.

Do you have any ideas on what I could look at or try from here?

I've got here randomly but it sounds like your background cannot have focus. On Android 7/7.1 there was a "problem" (it was not mistake) that there always had to be a focusable view and something had to be able to get the focus.

I would try to set "focusable" and "focusableintouchmode" for the background or call hiding the keyboard manually after appearing.

Also maybe this can help: SO

HideKeyboard example (I have this for XForms)

public void HideKeyboard()
{
    var activity = Platform.CurrentActivity;
    if (activity == null)
        return;

    var inputMethodManager = (InputMethodManager)activity.GetSystemService(AContext.InputMethodService);
    if (inputMethodManager == null)
        return;

    var token = activity.CurrentFocus?.WindowToken;
    if (token == null)
        return;

    inputMethodManager.HideSoftInputFromWindow(token, HideSoftInputFlags.None);
    activity.Window?.DecorView?.ClearFocus();
}
