Android Question Send SMS without appearing in "sent messages" of the device

[bgsoft]

If sending SMS to any of these two systems:

'1)
  Dim ps As PhoneSms
  Dim r As Reflector
  r.Target = r.RunStaticMethod("android.telephony.SmsManager", "getDefault", Null, Null)
  r.RunMethod4("sendTextMessage", Array As Object("phone number", Null, "Hello", Null, Null), _
  Array As String("java.lang.String", "java.lang.String", "java.lang.String","android.app.PendingIntent", "android.app.PendingIntent"))

'-------------------------------------------------------------------------------------------------

'2)
Dim Sms1 As PhoneSms
Sms1.Send(phone number,"hello")

The message appears in "sent messages" of the device
As I can send an SMS, without appearing in "sent messages" of the device?

thanks

The two code snippets are more or less the same.

You can delete the message after you sent it (see SMS from the Phone library).

thanks Erel

Hi Erel

Forgive my ignorance. I have looked all phone library. And I not find anything to delete from the list of device sent an SMS.

Please, you can put a line of code on how to do?

thanks

 

[Erel]

Try this:

Dim cr As ContentResolver
cr.Initialize("cr")
Dim u As Uri
u.Parse("content://sms")
Log(cr.Delete(u, "_id = ?", Array As String(<id>))) 'should print 1

Note that starting from Android 4.4 only the default SMS app can delete messages.

You need to add this permission:

 AddPermission(android.permission.WRITE_SMS)

Thank you so much for your quick response and example

Erel,

Note that starting from Android 4.4 only the default SMS app can delete messages.

So this code won't prevent the message from appearing in the Message app on Android 4.4 and higher?

Sub Service_Create   
    Dim SI As SmsInterceptor
    SI.Initialize2("SI", 999)
End Sub
Sub SI_MessageReceived (SMSSender As String, SMSBody As String) As Boolean 
    Dim ReturnValue As Boolean
    If SMSBody.ToLowerCase.StartsWith("TrapThisOne(") Then        'Filter for our messages here
        SMS_Sender = SMSSender        'Store in Globals for responding routines to use
        SMS_Body = SMSBody            'Store in Globals for responding routines to use
        Select Case SMS_Body
            Case "TrapThisOne(1)"
                'do Process 1
            Case "TrapThisOne(2)"
                'do Process 1
        End Select
        Log(ModuleName & ".SI_MessageReceived: Ours" & SMSSender & ":[" & SMSBody & "]")
        ReturnValue = True        'tell OS that we've handled this one
    Else
        Log(ModuleName & ".SI_MessageReceived: Not Ours:" & SMSSender & ":[" & SMSBody & "]") 
        ReturnValue = False        'Not one of ours- let the default handler take this message
    End If
    Return ReturnValue
End Sub

Will the delete solution (post #5) get both sent and received messages?

Thanks,

Jim

When I install some apk, I received sms message by apk name. There isn't sender phone number. How should it makes like that? My English is not good.

My English is not good

OK but what do you mean ?

There isn't sender phone number.

Do you mean you don't find a phone number to send the message to ? If yes, you have to provide the number yourself.
Or do you mean : some apps don't find your own phone number ?

Thanks

 

[koaunglay]

I mean I can't find phone number. Examples when I install hello.apk. I received sms from hello. Phone number is hello. Message is Thank U.

 

[lemonisdead]

Check if you don't have a Hello account in the Android's settings. If yes, you can be sure they use a separated db for their contact information.
You can do the same by using ContactsUtils for example and by adding your sender's number to the contacts with the name you want

 

[koaunglay]

Thanks a lot friend for your reply. But when I get message I didn't find in my contact. I mean there's no name hello in my contact. Thanks anyway!

You should ALWAYS create a new thread for your problem instead of posting to a OLD THREAD.
