If I create an Android app that sends texts, will the text show up in the default messaging app?

I would like to enable my users to send custom texts from within my app. These messages would be sent using their carrier via SMS. I've never done this before, but it looks like I should use the SmsManager Class provided in the Android API.
Is there a way to send the text without it displaying in their default text messaging app (i.e. Hangouts, Messenger etc.)? If that's possible, what happens when someone replies to the message that my app sent?

Yes, you can send SMS using the SmsManager, and You can try below code:
public void sendSMS(String phoneNo, String msg){
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, msg, null, null);
} catch (Exception ex) {
ex.printStackTrace();
}
}
Also you need to give SEND_SMS permission in AndroidManifest.xml to send message
<uses-permission android:name="android.permission.SEND_SMS" />
In case if your message text is more than 160 char.then you may change your code as below:
ArrayList<String> parts = smsManager.divideMessage(msg);
smsManager.sendMultipartTextMessage(phoneNo, null, parts, null, null);

You have to use SmsManagerclass to send text message.
firstly you have to get a instance of this class
SmsManager manager= SmsManager.getDefault();
then pass phone number and text message to sendTextmessage()
manager.sendTextMessage(phoneNo,null,textMessage,null,null);
You need to provide user permission also
<uses-permission android:name="android.permission.SEND_SMS" />

Yes it will show up.
After android KitKat version, it is not possible to avoid writing sms to sms provider.
After 4.4+ the default SMS app takes care of writing the sent messages to the sms provider. Also only the default messaging app have the permission to delete sms.

How do I stop my application from storing sent sms in default android message application?

Sorry if this has been answered but I can't find it anywhere and I've googled for 2 days now for the answer.
I am creating a application that can send a text message from a predefined list of numbers. When I send the messages they are getting stored in the default message application. Is there a way that I can stop this from happening, because if the user send 300 messages, they're going to get 300 names and what was sent in their default message application.
The code I'm using is:
public void sendMessage(String number, ArrayList<String> message) {
String _messageNumber = number;
ArrayList<String> messageText = message;
SmsManager sms = SmsManager.getDefault();
sms.sendMultipartTextMessage(_messageNumber, null, messageText, null, null);
}d

Doesn't seem possible anymore:
"Note: Beginning with Android 4.4 (API level 19), if and only if an app is not selected as the default SMS app, the system automatically writes messages sent using this method to the SMS Provider (the default SMS app is always responsible for writing its sent messages to the SMS Provider)."

Technically default message application doesn't store anything. It just reads messages from database of your mobile. So, it blindly reads all the messages and display it to you. You cant stop the app doing that. So, one way is make your own message database. Just sent the messages to whom ever you want. Later copy whole data to your custom database and delete those messages from default database.

Using the native sms app to send an sms without launching itself

I want to send an SMS, but not using the SmsManager class. I want to do it with the native SMS app which is there on an Android phone.
And here is the twist : I do NOT want to launch the native app while doing it. Is there some format of intent which can send an sms directly (given the sms-body and the phone number to send it to) via the native app (without the user having to click 'send').
I googled the same, but all results and responses simply launched the native sms, waiting for user to manually send the SMS. I have seen this being implemented in some apps like 'MightyText' and wish to implement in my app as well.
Please help !

Using the SmsManager will send the sms through the system but will not put it in the SMS content provider as was mentioned earlier. Hence any native messaging app will not see it.
To do so, you have to add it manually via the SMS content provider AFTER you send the message normally via SmsManager. Here's some sample code to help:
ContentValues values = new ContentValues();
values.put("address", "+12345678"); // phone number to send
values.put("date", System.currentTimeMillis()+"");
values.put("read", "1"); // if you want to mark is as unread set to 0
values.put("type", "2"); // 2 means sent message
values.put("body", "This is my message!");
Uri uri = Uri.parse("content://sms/");
Uri rowUri = context.getContentResolver().insert(uri,values);
And that's all. After that you'll notice that it's added and the native messaging app displays it normally.

Ok, so you want to send a SMS, without using SmsManager and plus it should show up in your native SMS app list?
Firstly, you cannot send SMS bypassing SmsManager. If you look at the source code of all native messaging app for Samsung Galaxy Nexus, it will invoke SmsManager on button click.
so, the below piece of code as posted above is correct
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
Secondly, after sending the message, native apps put it into into SMS ContentProvider
follow this How to save SMS to inbox in android?
Word of caution is that now adding to this is not supported. So you may have to resort to a hack to add it into the sent box.

If you only have ACTION_SENDTO, then, of course, any application that can send will pop up.
You need to add a filter for SMS
with URL. See https://stackoverflow.com/a/2372665/94363
or with content type https://stackoverflow.com/a/10613013/94363

I have done something similar in a project I was working on. You need to use SmsManager
It would be something like this -
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
You can use this to send an SMS programatically.

Try this:
String phoneNo = textPhoneNo.getText().toString();
String sms = textSMS.getText().toString();
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, sms, null, null);
Toast.makeText(getApplicationContext(), "SMS Sent!",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again later!",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
