Create new Android Project
Project Name: TextMessage
Build Target: Android 2.3.3 //or greater than that
Application Name: TextMessage
Package Name: com.shaikhhamadali.blogspot.textmessage
Create layout file: activity_messege_sender
Min SDK: 10 // or greater than that
1. create main layout:
Project Name: TextMessage

7. note that:
- code help taken from tech droid.
- donot forget to provide permission in manifest file either you can not send the message or will get the exception.
- The logic behind this is, send message through SmsManager and use broad cast receivers for deliveries.
8. conclusion:
- Some information about SmsManager,Broad Cast Receivers and permissions.
- Know how to send an sms.
- Know how to get notification of sms delivered.
9. about the post:
- Coming posts could be Receive Message,types of Intent,types of Toast ets
- The code seems to explain itself due to comments, and is very easy to understand.
- Don’t mind to write a comment whatever you like to ask, to know,to suggest or recommend.
- Hope you enjoy it!
