SendSMS Question

[AllyAndroid]

I am using the following code to send a text message. It works without any issues. However, I do get a warning telling me that the variable ps is never assigned a value. If I comment out the line: DIM ps As PhoneSms, the code no longer works.

I was wondering if someone could explain why it works if it is never assigned any value?

Sub SendSms(PhoneNumber As String, Text As String)
    Try
        Dim ps As PhoneSms
        Dim r As Reflector
 
        r.Target = r.RunStaticMethod("android.telephony.SmsManager", "getDefault", Null, Null)
        r.RunMethod4("sendTextMessage", Array As Object(PhoneNumber, Null, Text, Null, Null), _
            Array As String("java.lang.String", "java.lang.String", "java.lang.String", _
                "android.app.PendingIntent", "android.app.PendingIntent"))
        ToastMessageShow("Text was sent to " & PhoneNumber & ".",False)
    Catch
        ToastMessageShow("The text was  not sent to " & PhoneNumber & ".",False)
    End Try   
End Sub

That's just a warning, there's no problem, if you don't want to see that warning anymore just add a "'ignore" comment to that line, like this:

...
 
Dim ps As PhoneSms 'ignore
 
...

Thanks NJDude,

But I was looking more for an answer on how the line of code does anything. If all the code does is DIM it, how does it work?

This issue started showing up on B4A 2.7x, it is not really a problem, I believe is how the pre-compiler works now, nothing to worry about, I think Erel explained that on a post too.

It is related to permissions.

When you call Dim ps As PhoneSms the compiler adds the SEND_SMS permission to the manifest file. You can remove this line and add the permission with the manifest editor:

AddPermission(android.permission.SEND_SMS)

My guess is that this code snippet was written before the manifest editor was available.

Thanks Earl, that worked. I had added the following:

AddPermission(android.permission.WRITE_SMS)
AddPermission(android.permission.READ_SMS)

but didn't need the SEND_SMS until now.
