Today, we will cover yet another exciting topic. You might be well aware of the feature of sending SMS in android. Through this article, you will understand how you can send SMS to other devices using an application. For this, you need to know a few things.<\/p>\n

Two ways to Send SMS on Android<\/h3>\n

First, SMS means short message service. So, you understand that it\u2019s a service, and we term it as Messaging service. To send a message, you require the recipient\u2019s phone number.<\/p>\n

Now there are two ways to sending SMS in Android. They are as follows:<\/p>\n

1. Using SMS Manager API
\n2. Using Built-in Application to send SMS.<\/p>\n

Before going to any of the above methods, you need to add Send SMS permission in your manifest file. You can copy-paste the below in your manifest file.<\/p>\n

<uses-permission android:name=\"android.permission.SEND_SMS\"\/><\/pre>\n
Now let\u2019s see each of the methods along with code snippets.<\/p>\n
SMS Manager API<\/h4>\n
SMS Manager API is used to send text, data, and PDU messages. You can implement SMS Manager API by copying the below code.<\/p>\n
\/\/Creating SMS Manager object\r\nval smsManager: manager = SmsManager.getDefault()\r\n\r\n\/\/Calling sendTextMessage\r\nmanager.sendTextMessage(recepient_number, null, the_message, null, null)\r\n<\/pre>\n
Built-in Application Method<\/h4>\n
So, above, you saw how you could send messages using SMS Manager API. Now, you will know how you can use your built-in SMS application to send messages. You can find the code below for this method.<\/p>\n
val msg_uri = Uri.parse(\"smsto:recepient_phone_number\")\r\nval msgIntent = Intent(Intent.ACTION_SENDTO, msg_uri)\r\nmsgIntent.putExtra(\"message\", \"content of your message.\")\r\nstartActivity(msgIntent)\r\n<\/pre>\n
SMS Manager Class<\/h3>\n
SMS Manager Class, as you know, is used to send messages and data. Above you saw a way how you can use the SMS manager API to send a text message. Now we will see the other methods that are present in the SMS Manager Class.<\/p>\n
1. ArrayList<String> divideMessage()<\/strong>
\nThe divideMessage() method is used to split a long message into multiple sub-messages, each within the allowable character limit for a single SMS. This is particularly useful when you need to send lengthy text messages without truncation.<\/p>\n
2. void sendDataMessage()<\/strong>
\nThe sendDataMessage() method allows you to send messages that include binary data, such as multimedia content or application-specific data. This method is essential for sending complex messages beyond plain text.<\/p>\n
3. static SmsManager getDefault()<\/strong>
\nThe getDefault() method creates and returns an instance of the SmsManager class, which is essential for sending SMS messages. This method provides a default SmsManager that is configured for the device’s network.<\/p>\n
4. void sendTextMessage()<\/strong>
\nThe sendTextMessage() method sends an SMS message that contains only text. It requires parameters such as the recipient’s phone number, the message content, and optional parameters for delivery and sent intents.<\/p>\n
Implementation of Location-Based Services in Android.<\/h3>\n
So, after understanding the above concepts. We are ready to implement the concepts through a messaging application. The application will contain a button and two edit texts to send a message.<\/p>\n
Follow the below steps to achieve the goal.<\/p>\n
1:<\/strong> Launch your Android Studio.<\/p>\n
2:<\/strong> Select Create a New Project.<\/p>\n
\"Android<\/a><\/p>\n
3:<\/strong> Select Empty Activity and proceed.<\/p>\n
\"Android<\/a><\/p>\n
4:<\/strong> Enter your application name. In my case, it\u2019s \u201cTechVidvanSendSMS\u201d Next, select Kotlin from the dropdown. For the API level, select API 22 for now.<\/p>\n
5:<\/strong> Now, you need first to add the send SMS permission in your Manifest file.<\/p>\n
Code:AndroidManifest.xml<\/strong><\/p>\n
<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<manifest xmlns:android=\"http:\/\/schemas.android.com\/apk\/res\/android\"\r\n    package=\"com.techvidvan.techvidvansendsms\">\r\n    \r\n    <!--    Adding Permission to send SMS    -->\r\n    <uses-permission android:name=\"android.permission.SEND_SMS\"\/>\r\n    <application\r\n        android:allowBackup=\"true\"\r\n        android:icon=\"@mipmap\/ic_launcher\"\r\n        android:label=\"@string\/app_name\"\r\n        android:roundIcon=\"@mipmap\/ic_launcher_round\"\r\n        android:supportsRtl=\"true\"\r\n        android:theme=\"@style\/Theme.TechVidvanSendSMS\">\r\n        <activity android:name=\".MainActivity\">\r\n            <intent-filter>\r\n                <action android:name=\"android.intent.action.MAIN\" \/>\r\n\r\n                <category android:name=\"android.intent.category.LAUNCHER\" \/>\r\n            <\/intent-filter>\r\n        <\/activity>\r\n    <\/application>\r\n\r\n<\/manifest>\r\n<\/pre>\n
6:<\/strong> Now go to res —> layout —-> and open activity_main.xml. Now here, you need to add two edit texts and a button.<\/p>\n
Code: activity_main.xml<\/strong><\/p>\n
<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<LinearLayout xmlns:android=\"http:\/\/schemas.android.com\/apk\/res\/android\"\r\n    xmlns:tools=\"http:\/\/schemas.android.com\/tools\"\r\n    android:layout_width=\"match_parent\"\r\n    android:layout_height=\"match_parent\"\r\n    tools:context=\".MainActivity\"\r\n    android:layout_margin=\"20dp\"\r\n    android:orientation=\"vertical\">\r\n\r\n    <TextView\r\n        android:id=\"@+id\/title\"\r\n        android:layout_width=\"match_parent\"\r\n        android:layout_height=\"wrap_content\"\r\n        android:text=\"Tech Vidvan\"\r\n        android:textColor=\"#FF9800\"\r\n        android:textSize=\"30sp\"\r\n        android:textStyle=\"bold\"\r\n        android:gravity=\"center\"\r\n        android:padding=\"10dp\"\r\n        \/>\r\n    <EditText\r\n        android:id=\"@+id\/recipient_phone_number\"\r\n        android:layout_width=\"match_parent\"\r\n        android:layout_height=\"wrap_content\"\r\n        android:padding=\"20dp\"\r\n        android:layout_marginTop=\"50dp\"\r\n        android:hint=\"Enter Recipient's Phone Number \"\r\n        android:textColor=\"@android:color\/black\" \/>\r\n    <EditText\r\n        android:id=\"@+id\/your_message\"\r\n        android:layout_width=\"match_parent\"\r\n        android:layout_height=\"wrap_content\"\r\n        android:padding=\"20dp\"\r\n        android:layout_marginTop=\"10dp\"\r\n        android:hint=\"Please enter your message\"\r\n        android:textColor=\"@android:color\/black\" \/>\r\n    <Button\r\n        android:id=\"@+id\/send_your_sms\"\r\n        android:layout_width=\"wrap_content\"\r\n        android:layout_height=\"wrap_content\"\r\n        android:layout_gravity=\"center\"\r\n        android:layout_marginTop=\"15dp\"\r\n        android:onClick=\"sendSMS\"\r\n        android:text=\"Send Your Message\" \/>\r\n\r\n<\/LinearLayout>\r\n<\/pre>\n
7:<\/strong> Now, just open your MainActivity file and paste the below code.<\/p>\n
