Android Question Check if external keyboard is connected

[padvou]

Hello,
is it possible for an application to check if an external keyboard for example a barcode scanner via USB is connected? I mean already connected. I can detect the USB attach/detach, so I 'm interested in a device that's already connected when the application starts.

Try this code:

Dim p As Phone
If p.SdkVersion > 15 Then
   Dim ctxt As JavaObject
   ctxt.InitializeContext
   Dim inptmgr As JavaObject = ctxt.RunMethod("getSystemService", Array(ctxt.GetField("INPUT_SERVICE")))
   Dim inputs() As Int = inptmgr.RunMethod("getInputDeviceIds", Null)
   For Each i As Int In inputs
       Dim device As String = inptmgr.RunMethodJO("getInputDevice", Array(i)).RunMethod("getName", Null)
       Log(device)
   Next
End If

It should detect any connected input.

Thank you, it works great detecting USB connected input.
Why doesn't it work with bluetooth connected input and USB connected keyboard?

Hard to say. You can try to implement this solution with inline Java: https://stackoverflow.com/questions...usb-or-bluetooth-keyboard-attached-in-android

Replace Configuration with: android.content.res.Configuration
