Sending text messages to multiple recipients at once can be a useful feature for various scenarios, such as sending event reminders, invitations, or important announcements. If you’re an Android developer looking to implement this functionality in your app, this tutorial will guide you through the process step by step.
Step 1: Open your Android Studio and create a new project. Give it a suitable name and package.
Step 2: In the project structure, locate the "app" folder and expand it. Right-click on the "java" folder and create a new class called "SmsSender."
Step 3: In the "SmsSender" class, import the necessary packages:
"`java
import android.telephony.SmsManager;
"`
Step 4: Create a method called "sendSms" within the "SmsSender" class. This method will take two parameters: an array of recipient phone numbers and the message body.
"`java
public static void sendSms(String[] phoneNumbers, String message) {
SmsManager smsManager = SmsManager.getDefault();
for (String phoneNumber : phoneNumbers) {
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
}
}
"`
Step 5: Now, you can use the "sendSms" method to send messages to multiple phone numbers in your app. Simply call the method and pass the phone numbers and the message as arguments.
"`java
String[] recipients = {"+123456789", "+987654321", "+555555555"};
String message = "Hello, this is a test message!";
SmsSender.sendSms(recipients, message);
"`

Remember to respect recipients’ privacy and ensure you have appropriate consent to send text messages to multiple contacts.
How to send SMS via API?
Sending SMS via API requires integrating with a reliable SMS service provider. Here are the steps to send SMS via API:
1. Choose a reliable SMS service provider: Research and select an SMS service provider that offers a robust API for sending SMS. Consider factors such as pricing, delivery rates, user reviews, and documentation quality.
2. Register for an account: Sign up for an account with your chosen SMS service provider and ensure that your account is approved and active.
3. Obtain API credentials: Once you have an active account, the SMS service provider will provide you with API credentials. This typically includes an API key or token and may require additional authentication steps like client IDs or secret keys.
4. Review API documentation: Thoroughly go through the provider’s API documentation to understand the available endpoints, request format, required parameters, and response codes. Additionally, APIs usually provide code examples for different programming languages, making implementation easier.
5. Set up authentication: Most service providers use authentication methods like API keys, tokens, or OAuth. Set up authentication in your API integration code to ensure secure communication.
6. Construct API request: Structure your API request according to the documentation, including the recipient’s phone number, message content, and any additional parameters required. Format the request in the preferred data format, such as JSON or XML.
7. Implement API integration: Depending on the programming language or framework you are using, implement the necessary code to send the API request to the provider’s API endpoint. Use the appropriate HTTP methods (such as POST or GET) and include the required headers and parameters.
8. Handle the response: Once the API request is sent successfully, the SMS service provider will respond with a status code or acknowledgment indicating the delivery status. Handle the response in your integration code to determine the success or failure of the SMS delivery.
9. Error handling and retries (optional): Implement error handling mechanisms to handle various scenarios, such as network failures or incorrect API parameters. Additionally, you may choose to include retry mechanisms in case of temporary failures.
10. Testing and monitoring: Before deploying your SMS integration to production, thoroughly test it to ensure SMS messages are being sent successfully. Monitor your integration for any errors or issues after deployment and make necessary adjustments as required.
Remember to comply with any regulatory requirements or restrictions relating to SMS messaging, such as obtaining consent from recipients and respecting their privacy.

How to send SMS programmatically in Android?
To send SMS programmatically in Android, you can follow these steps:
1. Add the necessary permissions to your Android manifest: To send SMS messages, your app needs the SEND_SMS permission. Include the following line in your AndroidManifest.xml file within the manifest element:
"`xml
"`
2. Request permission at runtime: Starting from Android 6.0 (Marshmallow), you need to ask the user for permission to send SMS at runtime. You can check whether the permission is granted or not using the PackageManager, and request the permission if necessary.
3. Implement the SMS sending logic: To send an SMS, you will need to use the SmsManager class which provides methods for sending SMS messages. Here’s an example of how to send an SMS programmatically in Android:
"`java
import android.telephony.SmsManager;
public void sendSMS(String phoneNumber, String message) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
}
"`
In the example above, `phoneNumber` is the recipient’s phone number, and `message` is the content of the SMS you want to send. You can customize this method according to your application’s requirements.
4. Handle SMS delivery status (optional): If you need to track the delivery status of the SMS, you can register a BroadcastReceiver to receive the delivery report. The delivery report will contain the status of the sent SMS.
Remember to test your SMS sending functionality thoroughly on different Android devices and versions to ensure compatibility and proper handling of permissions.
