android – 通过WhatsApp发送消息意图

我怎么能从我的应用程序发送按摩到WhatsApp的特殊号码,我知道这个代码分享按摩组或联系whatsapp

Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.setType("text/plain");
String text = "Sorry For Interruption,I'm Just Trying Something";
waIntent.setPackage("com.whatsapp");

if (waIntent != null) {
    waIntent.putExtra(Intent.EXTRA_TEXT, text);//
    startActivity(Intent.createChooser(waIntent,"Share with"));

但我想按照特殊号码发送按摩,如“966xxxxxxx”我怎么能这样做？
