Android phones can send and receive text messages to and from any other phone that supports SMS (SMS). When it comes to sending SMS messages, you have two options: With the ACTION SENDTO intent action, use an implicit Intent to launch a messaging app. This is the most straightforward method of sending messages.
Built-in SMS application:
putExtra("sms_body", "default content"); sendIntent. setType("vnd. android-dir/mms-sms"); startActivity(sendIntent); Of course, both need SEND_SMS permission.
Messages allows you to send and receive text messages.
Open the Messages app on your phone.
Select Compose from the drop-down menu.
Enter the names, phone numbers, or email addresses you'd like to message in the "To" field.
You have the option of selecting from your top contacts or your whole contact list.
Using the Dalvik Debug Monitor Service (DDMS) tool in Eclipse or the Telnet client, you may simulate sending SMS messages to the Android emulator.
Share a personalized message with your friends.
