android launch SMS intent without any recipient

Question

我想从我的应用程序中打开Android SMS应用程序，我不想将任何联系人设置为收件人，如何？

Answer 1

Uri uri = Uri.parse("smsto:");
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", "Hello World!");  
startActivity(intent);

note

this way doesn't need any permission in Manifest
