Android Question Answer Call in Service

[palmzac]

Hi,
I have a problem that my project need to auto answer call for special reason. AnswerCall Lib does not work. I try this code. But, It does not work too. Would you help me ? Thanks !

Sub GetContext As JavaObject
  Return GetBA.GetField("context")
End Sub

Sub GetBA As JavaObject
  Dim jo As JavaObject
  Dim cls As String = Me
  cls = cls.SubString("class ".Length)
  jo.InitializeStatic(cls)
  Return jo.GetFieldJO("processBA")
End Sub

Sub answerCall
   
    Log("Answer Call !!!!")
  
   Dim ke As JavaObject
   Dim i1 As Intent
 
   Try
          
     i1.Initialize("android.intent.action.MEDIA_BUTTON","")       
     ke.InitializeNewInstance("android.view.KeyEvent", Array As Object(1,  KeyCodes.KEYCODE_HEADSETHOOK ))    
     i1.PutExtra("android.intent.extra.KEY_EVENT", ke)
         
     GetContext.RunMethod("sendOrderedBroadcast", Array As Object(i1,"android.permission.CALL_PRIVILEGED"))
  
   Catch
     ToastMessageShow(LastException.Message,True)
     Log("answer_call() " & LastException.Message)
   End Try

End Sub

There is no reliable way to answer calls in Android.

I do confirm. One workaround I found was to use the keygen library (with the threading one) for the KEYCODE_HEADSETHOOK to be received by the whole system (don't ask me why but seems to work on devices where AnswerCall doesn't not work).
I am lacking understanding

Edit: library I use https://www.b4x.com/android/forum/threads/simulate-hardware-keypress.20804/#post-120246

Badly ! The problem is that the KEYGEN lib does not work on service. It work on Activity only.

Please would you test the project attached. Take a look at the logs (I should have put comments in the code, just for you)

OMG ! Unfortunately !
The problem is that It does not work on screen-off state .
