Also note that the Hangouts application will currently block my BroadcastReceiver from receiving SMS messages. I had to disable SMS functionality in the Hangouts application (Settings->SMS->Turn on SMS), before my SMS BroadcastReceived started getting fired.

Edit: It appears as though some applications will abortBroadcast() on the intent which will prevent other applications from receiving the intent. The solution is to increase the android:priority attribute in the intent-filter tag:

<receiver android:name="com.company.application.SMSBroadcastReceiver" >
  <intent-filter android:priority="500">
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
  </intent-filter>
</receiver>

android provider telephony SMS RECEIVED is not correct because Telephony is a class and it should be capital as in android provider Telephony SMS RECEIVED

Stumbled across this today  For anyone coding an SMS receiver nowadays  use this code instead of the deprecated in OP   SmsMessage   msgs   Telephony Sms Intents getMessagesFromIntent intent   SmsMessage smsMessage   msgs 0

I ve encountered such issue recently  Though code was correct  I didn t turn on permissions in app settings  So  all permissions hasn t been set by default on emulators  so you should do it yourself

android provider Telephony SMS RECEIVED has a capital T  and yours in the manifest does not   Please bear in mind that this Intent action is not documented

For android 19  you can get it in Telephony Sms Intents SMS RECEIVED ACTION   There are more in the Intents class that  re worth looking  at

Your broadcast receiver must specify android exported  true  to receive broadcasts created outside your own application  My broadcast receiver is defined in the manifest as follows    lt receiver     android name   IncomingSmsBroadcastReceiver      android enabled  true      android exported  true   gt       lt intent-filter gt           lt action android name  android provider Telephony SMS RECEIVED    gt       lt  intent-filter gt   lt  receiver gt    As noted below  exported  true  is the default  so you can omit this line  I ve left it in so that the discussion comments make sense

intent getAction   equals SMS RECEIVED   I have tried it out successfully

User · Answer

I tried your code and found it wasn t working   I had to change   if  intent getAction      SMS RECEIVED      to   if  intent getAction   equals SMS RECEIVED       Now it s working  It s just an issue with java checking equality
