You’ll need to register a broadcast receiver for android.provider.Telephony.SMS_RECEIVED. The receiver can then check the number of the SMS and start your activity as appropriate.

So, you’ll need to:

• Add a uses-permission for android.permission.RECEIVE_SMS to your manifest

• Declare a broadcast receiver in your <application/> element in the manfiest:

  <receiver android:name=".YourReceiverName"> 
      <intent-filter> 
          <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
      </intent-filter> 
  </receiver>
  

• Create the receiver class, extending IntentReceiver.

• In onReceiveIntent, you can get the relevant messages by calling Telephony.Sms.Intents.getMessagesFromIntent() and passing in the intent you’re supplied.
• If the number matches the one you want, you can then start an activity by calling startActivity
