What permission should my receiver receive to receive SMS messages from the system?

Question

I have a BroadcastReceiver statically registered in my Android app that processes incoming SMS messages, for example:

<receiver android:name=".receivers.SmsReceiver" android:exported="true" > <intent-filter android:priority="100" > <action android:name="android.provider.Telephony.SMS_RECEIVED" /> </intent-filter> </receiver> 

Lint notes this with a warning, which causes the recipient to be exported without any permissions from the caller. If I set the exported property to false, the system will not be able to call my recipient after receiving an SMS message.

So, what permission should I require from the System when registering my receiver for processing incoming SMS messages?

Edit:

I do not ask for the "uses-permission" tag, which allows my application to receive SMS messages. I am asking for the correct "android: permission" value for my receiver, so only the system can send broadcast messages like this, and the other application cannot replace such an event for my application.

eg:.

  <receiver android:name=".receivers.SmsReceiver" android:exported="true" android:permission="com.android.permission.SOME_PERMISSION_ONLY_THE_SYSTEM_HAS"> <intent-filter android:priority="100" > <action android:name="android.provider.Telephony.SMS_RECEIVED" /> </intent-filter> </receiver> 

Answer 1

Use android: priority = "2147483647" instead of android: priority = "100" because suppose you have any application whose priority is high compared to your priority, like u, then your broadcast will never report this . also check this permission in your android mainfest permission: name = "android.permission.RECEIVE_SMS"
