android - 通过并行whatsapp发送消息到未保存的号码

Question

我正在尝试通过 Whatsapp 向未保存的号码发送消息，我有两个 whatsapp，我正在获取选择器但无法向其中添加号码，它显示了我最近的联系人列表。

我尝试了 Uri、PackageManager 和很多东西，但没有输出

num = "91" + edt_num.getText().toString();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hi, This is me");
sendIntent.putExtra("jid", num + "@s.whatsapp.net");
sendIntent.setPackage("com.whatsapp");
if (sendIntent.resolveActivity(getPackageManager()) == null) {
                    Toast.makeText(MainActivity.this, "Error/n", Toast.LENGTH_SHORT).show();
                    return;
}
startActivity(sendIntent);

使用此功能向未保存的号码发送消息

phoneNumber 中必须使用国家代码，例如 91xxxxxxxxxx

public void SendWhatsappMessage(String phoneNumber,String message){
        PackageManager pm = getPackageManager();
        Intent send= new Intent(Intent.ACTION_VIEW);
        try {
            String url = "https://api.whatsapp.com/send?phone="+ phoneNumber +"&text=" + URLEncoder.encode(message, "UTF-8");
            send.setPackage("com.whatsapp");
            send.setData(Uri.parse(url));
            if (send.resolveActivity(pm) != null) {
                startActivity(send);
            }
        } catch (Exception e){
            e.printStackTrace();
        }
    }
