Android Question How to send sms on Android 34?

jefflynn1974 · 2024-11-07T12:29:38+0000

I have an app that has been working for years, but now I want to update it to the latest android sdk. This is I have done so far. I have updated b4a to version 13.00, jdk to 19.0.2, the android sdk to 34. I use the following code to send sms:

Send sms:

        beep.Initialize(300, 500) '300 milliseconds, 500 hz
        Log("0")
        beep.Beep
        Log("1")
        Dim p As PhoneSms
        Log("2")
        p.Send(title.SubString(title.IndexOf(":")+1),body)
        Log("3")

and I get the following log:

Error log:

My question is, how to do this properly?

Send SMS from B4A code

I am looking for any working library for sending SMS directly from B4A code without user intervention . By using "Intet" , it need user action to click "Send" Button in messaging app. Dim In As Intent In.Initialize(In.ACTION_VIEW, "sms:" & number) In.PutExtra("sms_body", "this is...

www.b4x.com

Basically, your app can not send an SMS without user intervention unless:

1) Your app is configured to be the "default" sms app for the device (which will disable the factory SMS app that came with the phone)
2) Or use a third party service like Twilio to send the SMS (but then it will NOT be from the devices phone number, it will be from the number reserved with the third-party service)

And Erels answer in the same Thread

@JohnC is correct (https://www.b4x.com/android/forum/t...og-permissions-are-no-longer-available.98100/).
The only exception is for non-Google Play apps.

If your App is in the Playstore then you can not Send SMS on your Device anylonger.

Have you tried to use an Intent?

B4X:

Dim in As Intent
    in.Initialize(in.ACTION_VIEW, "sms:")
    in.PutExtra("sms_body", "this is the body")
    StartActivity(in)

Not sure if this code i found is still valid in 2024 though.

Thank you for your answer. This is a private app, not uploaded in Play Store. The code I wrote ealrier has been working for years and it would be great if it worked without user intervention. I am the only user and I'm too lazy to press the send button

you should not set targetsdk to a high value. Restore the old value you used in the past.

Here you go, this is extract from one of our apps. You can adapt it for your needs. You can put in in a class, this code is from a service

B4X:

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
   
    Dim    NativeMe                 As JavaObject
    Dim PE                         As PhoneEvents
    Dim smsParts, smsPartsACK     As Int

End Sub


Sub Service_Create
   
Try
        ' // phone events
        PE.Initialize("PE")        
    Catch
log($"svc_sms::Service_Create:: - error -  ${LastException.Message}"$)
    End Try

End Sub

Sub Service_Start (StartingIntent As Intent)
 
   Try
        NativeMe.InitializeContext
    Catch
        log($"svc_sms::Service_Start:: - error -  ${LastException.Message}"$)
    End Try
   
End Sub

Sub SendLargeSMS(Destination As String, Message As String)
   
    Dim Extra As Map, id As String, ph As Phone

   
    id = DateTime.now
    Extra.Initialize
    Extra.Put("message_id", id )
    Dim tM As String = DateTime.Now
    Extra.Put("message_time", tM)
   
    Try
        smsPartsACK = 0
        If ph.SdkVersion >= 31 Then
            smsParts = NativeMe.RunMethod("Send4", Array(Destination, Message, Extra, True, False))
        Else
            smsParts = NativeMe.RunMethod("Send3", Array(Destination, Message, Extra, True, False))
        End If
        If smsParts = 0 Then
            smsParts = 1
        End If       
    Catch       
       
        log($"SendLargeSMS_ERROR ${LastException.Message}"$)
    End Try
   
End Sub
