使用SQLite中的Number将Msg发送到Whatsapp

Question

是否可以从存储在数据库中的号码发送whatsapp（SQLite） 所以我已经尝试从较旧的帖子发送一个whatsapp但它发送ony消息或只打开联系人当我结合两者我没有得到任何结果 //这将在Whatsapp上打开特定联系人

void openWhatsappContact() {
    String number = "919033152265";
    Uri uri = Uri.parse("smsto:" + number);
    Intent i = new Intent(Intent.ACTION_SENDTO, uri);
    i.setPackage("com.whatsapp");  
    startActivity(Intent.createChooser(i, ""));
}

//这将发送特定消息到WhatsAPP

public void SelectContactAndMsgSend(View view) {

    Intent waIntent = new Intent(Intent.ACTION_SEND);
    waIntent.setType("text/plain");
            String text = "YOUR TEXT HERE";
    waIntent.setPackage("com.whatsapp");
    if (waIntent != null) {
        waIntent.putExtra(Intent.EXTRA_TEXT, text);//
        startActivity(Intent.createChooser(waIntent, "Share with"));
    } else {
        Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                .show();
    }

}

//两者都没有得到任何结果

public void CombiningBoth(View view) {
    String number = "Here GOes My Number"; //As i am from india my number Im putting is 91xxxxxxxxxx
    Uri uri = Uri.parse("smsto:" + number);
    Intent waIntent = new Intent(Intent.ACTION_SENDTO, uri);

    waIntent.setType("text/plain");
            String text = "YOUR TEXT HERE";
    waIntent.setPackage("com.whatsapp");
    if (waIntent != null) {
        waIntent.putExtra(Intent.EXTRA_TEXT, text);//
        startActivity(Intent.createChooser(waIntent, ""));
    } else {
        Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                .show();
    }
