Android Question Phone call without dialer

[Colin Evans]

Just trying to use an app that I did sometime ago and now when I try and make a telephone call it returns a error

This works but brings up the dialler

Sub button1_click
    rp.CheckAndRequest(rp.PERMISSION_READ_PHONE_STATE)
    Wait For Activity_PermissionResult(permission As String,result As Boolean)
    If result Then
        Dim result2 As Int
        result2 = Msgbox2("Dog In The Lane", "Do you wish to dial the number ?", "Yes", "", "No", Null)
        If result2 = DialogResponse.Positive Then
            Dim i As Intent
            i.Initialize(i.ACTION_VIEW, "tel:01939210000") 'dummy number but I use the xorrect number in the app
            StartActivity(i)
            'Dim p As PhoneCalls
            'StartActivity(p.Call("01939210000")) 'dummy number
        End If
    End If
End Sub

It works now I've changed the code to use Dim i as intent but brings up the dialler interface, it now doesn't work if I rem out those lines and un-rem the Dim p as PhoneCalls ans StartActivity(p.call( etc

As something changed that you can't use PhoneCalls

This doesn't work but used to

Sub button1_click
    rp.CheckAndRequest(rp.PERMISSION_READ_PHONE_STATE)
    Wait For Activity_PermissionResult(permission As String,result As Boolean)
    If result Then
        Dim result2 As Int
        result2 = Msgbox2("Dog In The Lane", "Do you wish to dial the number ?", "Yes", "", "No", Null)
        If result2 = DialogResponse.Positive Then
            'Dim i As Intent
            'i.Initialize(i.ACTION_VIEW, "tel:01939210000") 'dummy number but I use the xorrect number in the app
            'StartActivity(i)
            Dim p As PhoneCalls
            StartActivity(p.Call("01939210000")) 'dummy number
        End If
    End If
End Sub

and returns the error

1.

CALL_PHONE is a dangerous permission

2.
As you need this permission you also need to request this permission with runtimepermissions.

See https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/

Requesting rp.PERMISSION_READ_PHONE_STATE is the wrong permission. You need it TOO maybe.

At the end i fear that it will only work if your app is the devices default dialer app
