SMS Radar Build Status Maven Central Android Arsenal

Read incoming and outgoing text messages using an Android application across different Android SDK versions it's not trivial. If yo don't want to appear as SMS application and your application has to read incoming and outgoing SMSs this is your library.

This Android library offers you two main classes to use to start listening text messages. SMS Radar is implemented in top of an Android service. To start / stop listening text messages use SmsRadar.initializeSmsRadarService(context, listener) with a Context instance and a SmsListener implementation.

Each time the device owner receives one SMS the SmsListener used to initialize SmsRadarService service will be notified in on onSmsSent(Sms sms) or onSmsReceived(Sms sms) methods.

The SMS information provided on SmsListener methods is:

  • SMS address. MSISDN used to send/receive the SMS.
  • SMS date. SMS local creation date.
  • SMS content. Message sent in the SMS.
  • SMS type. One SMS can be received or sent. Review SmsType enum if need it.

This library works on Android 2.X or higher versions.
