Automatic telephone call

[anallie0]

hi
I have a button in my app, when I press it to do a phone number and call.
I used this code,

Sub tel4_Click
   Dim result As Int
      result = Msgbox2("1530", "Vuoi chiamare la guardia costiera ?", "Si", "", "No", Null)
   If result = DialogResponse.Positive Then 
   Dim i As Intent
   i.Initialize(i.ACTION_VIEW, "tel:036275735")
   StartActivity(i)
   End If
End Sub

Open the dialer, but not start the call.
How do I start the phone call ?

Thanks

Try this:
- Add this line to the manifest editor:

AddPermission(android.permission.CALL_PHONE)

- Change i.ACTION_VIEW to i.ACTION_CALL

thanks Erel
now everything works except for one number (112) that in Italy is an emergency number and that you call do without credit.
By dialing this number you open the Diale but not start of the call.
Is there any way to overcome this?

Is there any way to overcome this?

Yes. Change the permission to: android.permission.CALL_PRIVILEGED

 

[anallie0]

does not work

If I replace
AddPermission(android.permission.CALL_PHONE)
with
AddPermission(android.permission.CALL_PRIVILEGED)
tells me that missing android.permission.CALL_PHONE
if I add AddPermission(android.permission.CALL_PRIVILEGED)
does not change anything.

Seems like this permission is not documented correctly and can only be used by system apps: Issue 10344 - android - Permission CALL_PRIVILEGED not working as advertised - Android - An Open Handset Alliance Project - Google Project Hosting

You will not be able to directly call emergency numbers.

I read the link, now everything is clear.

End a phone call

I´d like to make some call (no problem), but now after for example 30 seconds I need to shut down this call. Is there any way to make it without using airplane mode ?

Thanks

Basic4android Search: end call

See result number 9.

I have a similar, almost equal, problem as at the start of this thread.

My code is as follows

Sub BtnTel_Click
    Dim Ph As Intent
    Ph.Initialize(Ph.ACTION_CALL, TBTel.Text)
    StartActivity(Ph)

End Sub

TBTel.Text contains a valid telephone number like + 31553556554.



The program stops at the line StartActivity(Ph) with the message:
Last exception android content ActivityNotFoundException: No activity found to handle intent

I have added AddPermission(android.permission.CALL_PRIVILIGED) with the manifest editor. CALL_PHONE doesn't work either.

What am I doing wrong?

You should use PhoneCalls object from the Phone library.

how do I know when it was serviced?

how do I know when it was serviced?

Hello,
You have to use the PhoneEvents and check the PhoneStateChanged event. When it changed from IDLE to OFFHOOK and returns to IDLE, you know your call was serviced (of course after having programmatically generated the phone call).
