SMS_RECEIVED的动态广播注册不起作用

Question

Registering broadcast receiver for SMS_RECEIVED action in AndroidManifest.xml file

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

works as expected, SmsReceiver.onReceive(Context context, Intent intent) is called. Trying to register dyamically

 Intent inte = registerReceiver(
                 new SmsReceiver(), 
                 new IntentFilter(Telephony.Sms.Intents.SMS_RECEIVED_ACTION));

SmsReceiver.onReceive(Context context, Intent intent) is never called.

notice

• Device API Level is LOWER than 23 so it's not runtime request permission problem
• tried IntentFilter.setPriority(1000) with no success.
• registerReceiver returns null

How can i fix that ?

Start by using the correct Intent action.

There are two action strings related to SMS delivery. What works for any app — and what you are using in the <intent-filter> — is SMS_RECEIVED_ACTION . What only works for the user's chosen SMS client — and what you are trying to use with the IntentFilter — is SMS_DELIVER_ACTION . These are not the same.
