如何在 Android 中使用 C++ Builder 发送短信

While searching the internet I came across the topic of sending SMS but unfortunately I did not find any example for C ++ Builder. Everything is written in Delphi. I tried to rewrite the instructions in C ++ and got this code:

#include <Androidapi.Helpers.hpp>
#include <Androidapi.JNI.JavaTypes.hpp>
#include <Androidapi.JNI.Telephony.hpp>
#include <Androidapi.JNI.GraphicsContentViewText.hpp>
#include <Androidapi.JNI.App.hpp>
#include <Androidapi.JNI.Net.hpp>

JString* wiadomosc = StringToJString( L"Wiadomość" );
Jnet_Uri* URI;
JString* destAdress;

 URI = StrToJURI( "12345678" ); // phone number
 _di_JIntent Intent = TJIntent::JavaClass->init( TJIntent::JavaClass->ACTION_VIEW, URI );  //ACTION_VIEW  ACTION_SEND
 Intent->setType( StringToJString("text/plain") );
 //Intent->putExtra( TJIntent::JavaClass->EXTRA_TEXT, wiadomosc ); StringToJString('sms_body')
 Intent->putExtra( StringToJString("sms_body"), wiadomosc );

 ::SharedActivityContext()->startActivity( Intent );
 //SharedActivity()->startActivity(Intent);

该程序有效但不像我预期的那样。出现应用程序选择窗口，尽管将永久短信设置为默认设置，但即使代码中存在该数据，我也无法在不输入电话号码和短信的情况下发送短信。请给我提示如何在不使用 Android 上的默认程序的情况下发送短信。
