Android SMS Broadcast Receiver doesn't work

Question

Hi I'm trying to catch the sms content and use in my app, so I made a BroadcastReceiver with Permission and Manifests But when the device receive sms, my code doesn't run which means that the BroadcastReceiver doesn't fire. I also checked many Articles inside and outside here, there're some:

Android Sms Receiver Result to Main Activity SMS receiver didn't work

Android SMS Receiver not working

Broadcast Receiver not working for SMS

Here is a part of my Manifest:

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<application.
...
...
<receiver android:name="com.example.android.receiver.SmsReceiver"
            android:permission="android.permission.BROADCAST_SMS">
            <intent-filter android:priority="2147483647">
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
</application>

And This is my Receiver

public class SmsReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "SMS Received!", Toast.LENGTH_LONG).show();
    }
}

I also tried to register the receiver dynamically inside activity onCreate() but nothing changed

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
intentFilter.setPriority(2147483647);
registerReceiver(new SmsReceiver(), intentFilter);

Does anyone know where is the problem? It should just Toast that a message is recieved so I can continue work but the receiver doesn't seem to even fire

You should read Automatic SMS Verification.

public abstract Task startSmsRetriever ()

Starts SmsRetriever, which waits for a matching SMS message until timeout (5 minutes). The matching SMS message will be sent via a Broadcast Intent with action SmsRetriever.SMS_RETRIEVED_ACTION.

When you are ready to verify the user's phone number, get an instance of the SmsRetrieverClient object, call startSmsRetriever, and attach success and failure listeners to the SMS retrieval task:

SmsRetrieverClient mClient = SmsRetriever.getClient(this);
Task<Void> mTask = mClient.startSmsRetriever();
mTask.addOnSuccessListener(new OnSuccessListener<Void>() {
  @Override public void onSuccess(Void aVoid) {
    Toast.makeText(YourActivity.this, "SMS Retriever starts", Toast.LENGTH_LONG).show();
  }
});
mTask.addOnFailureListener(new OnFailureListener() {
  @Override public void onFailure(@NonNull Exception e) {
    Toast.makeText(YourActivity.this, "Error", Toast.LENGTH_LONG).show();
  }
});

When a verification message is received on the user's device, Play services explicitly broadcasts to your app a SmsRetriever.SMS_RETRIEVED_ACTION Intent, which contains the text of the message. Use a BroadcastReceiver to receive this verification message.

public void onReceive(Context context, Intent intent) {
    if (SmsRetriever.SMS_RETRIEVED_ACTION.equals(intent.getAction())) {
      Bundle extras = intent.getExtras();
      Status status = (Status) extras.get(SmsRetriever.EXTRA_STATUS);

      switch(status.getStatusCode()) {
        case CommonStatusCodes.SUCCESS:
          // Get SMS message contents
          String message = (String) extras.get(SmsRetriever.EXTRA_SMS_MESSAGE);
          // Extract one-time code from the message and complete verification
          // by sending the code back to your server.
          break;
        case CommonStatusCodes.TIMEOUT:
          // Waiting for SMS timed out (5 minutes)
          // Handle the error ...
          break;
      }
    }
  }

Register Your BroadcastReceiver with the intent filter com.google.android.gms.auth.api.phone.SMS_RETRIEVED in your app's AndroidManifest.xml file.

<receiver android:name=".YourBroadcastReceiver" android:exported="true">
    <intent-filter>
        <action android:name="com.google.android.gms.auth.api.phone.SMS_RETRIEVED"/>
    </intent-filter>
</receiver>

Finally, Register your BroadcastReceiver in your onCreate() section.

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(SmsRetriever.SMS_RETRIEVED_ACTION);
getApplicationContext().registerReceiver(broadcastReceiverOBJ, intentFilter);
