BroadcastReceiver SMS_Received not working on new devices

Question

After going through several resources and questions, I still face a problem with detecting an incoming SMS message.

The code below shows the basics:

Answer 1

Please make sure your implementation is like this.

SMS Receiver class

    public class SmsReceiver extends BroadcastReceiver {

        private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";

        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals(SMS_RECEIVED)) {
                Bundle bundle = intent.getExtras();
                if (bundle != null) {
                    // get sms objects
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    if (pdus.length == 0) {
                        return;
                    }
                    // large message might be broken into many
                    SmsMessage[] messages = new SmsMessage[pdus.length];
                    StringBuilder sb = new StringBuilder();
                    for (int i = 0; i < pdus.length; i++) {
                        messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                        sb.append(messages[i].getMessageBody());
                    }
                    String sender = messages[0].getOriginatingAddress();
                    String message = sb.toString();
                    Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
                    // prevent any other broadcast receivers from receiving broadcast
                    // abortBroadcast();
                }
            }
        }
    }

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.smsreceiver"
    android:versionCode="1"
    android:versionName="1.0">
    <uses-sdk android:minSdkVersion="4" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity
           // your activity
        </activity>
        <receiver android:name="com.example.smsreceiver.SmsReceiver" android:enabled="true">
            <intent-filter android:priority="2147483647">
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

Make sure you use your own defined package. package defined here is dummy.

Answer 2

Okay the problem was resolved. The issue did not reside with priorities, but with my phone being a Nexus 6P (a.k.a. API 23).

Providing permissions in the manifest.xml alone wasn't enough and I had to add code for runtime permission request. See Android documentation for runtime permissions

Add this code to your MainActiviy:

ActivityCompat.requestPermissions(this, 
            new String[]{Manifest.permission.RECEIVE_SMS},
            MY_PERMISSIONS_REQUEST_SMS_RECEIVE);

Define this at the top of MainActivity Class:

private int MY_PERMISSIONS_REQUEST_SMS_RECEIVE = 10;

And also add this override:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == MY_PERMISSIONS_REQUEST_SMS_RECEIVE) {
        // YES!!
        Log.i("TAG", "MY_PERMISSIONS_REQUEST_SMS_RECEIVE --> YES");
    }
}
