Read All SMS from Android

Question

I recently been trying to develop a Flutter Project which can read all the SMS from Android phone ( i have android phone ).

and I am using the below code

import 'package:flutter/material.dart';
import 'package:flutter_sms_inbox/flutter_sms_inbox.dart';
import 'package:permission_handler/permission_handler.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final SmsQuery _query = SmsQuery();
  List<SmsMessage> _messages = [];

  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter SMS Inbox App',
      theme: ThemeData(
        primarySwatch: Colors.teal,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: const Text('SMS Inbox Example'),
        ),
        body: Container(
          padding: const EdgeInsets.all(10.0),
          child: _messages.isNotEmpty
              ? _MessagesListView(
                  messages: _messages,
                )
              : Center(
                  child: Text(
                    'No messages to show.\n Tap refresh button...',
                    style: Theme.of(context).textTheme.headlineSmall,
                    textAlign: TextAlign.center,
                  ),
                ),
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: () async {
            var permission = await Permission.sms.status;
            if (permission.isGranted) {
              final messages = await _query.querySms(
                kinds: [
                  SmsQueryKind.inbox,
                  SmsQueryKind.sent,
                ],
                // address: '+254712345789',
                count: 10,
              );
              debugPrint('sms inbox messages: ${messages.length}');

              setState(() => _messages = messages);
            } else {
              await Permission.sms.request();
            }
          },
          child: const Icon(Icons.refresh),
        ),
      ),
    );
  }
}

class _MessagesListView extends StatelessWidget {
  const _MessagesListView({
    Key? key,
    required this.messages,
  }) : super(key: key);

  final List<SmsMessage> messages;

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      shrinkWrap: true,
      itemCount: messages.length,
      itemBuilder: (BuildContext context, int i) {
        var message = messages[i];

        return ListTile(
          title: Text('${message.sender} [${message.date}]'),
          subtitle: Text('${message.body}'),
        );
      },
    );
  }
}

but still it is not able to show the sms from my phone instead it is showing me error

E/flutter ( 7900): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(error, Permission Denial: reading com.android.providers.telephony.SmsProvider uri content://sms/inbox from pid=7900, uid=10284 requires android.permission.READ_SMS, or grantUriPermission(), null, java.lang.SecurityException: Permission Denial: reading com.android.providers.telephony.SmsProvider uri content://sms/inbox from pid=7900, uid=10284 requires android.permission.READ_SMS, or grantUriPermission()

I am using this dependancy flutter_sms_inbox: ^1.0.3 and I am also using the code given at the example tab of this dependancy

Answer 1

The error indicates that your application doesn't have the necessary permissions to read SMS messages from the Android device

You need to add

<uses-permission android:name="android.permission.READ_SMS"/>

to your flutter project/android/AndroidManifest.xml

You also need to ensure READ_SMS is granted before requesting

Sample

import 'package:flutter/material.dart';
import 'package:flutter_sms_inbox/flutter_sms_inbox.dart';
import 'package:permission_handler/permission_handler.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final SmsQuery _query = SmsQuery();
  List<SmsMessage> _messages = [];

  @override
  void initState() {
    super.initState();
    // Request SMS permission when the app starts
    _requestSmsPermission();
  }

  // Function to request SMS permission
  Future<void> _requestSmsPermission() async {
    if (await Permission.sms.request().isGranted) {
      // Permission is granted, query SMS messages
      _querySmsMessages();
    }
  }

  // Function to query SMS messages
  Future<void> _querySmsMessages() async {
    final messages = await _query.querySms(
      kinds: [
        SmsQueryKind.inbox,
        SmsQueryKind.sent,
      ],
      count: 10,
    );
    debugPrint('sms inbox messages: ${messages.length}');

    setState(() => _messages = messages);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter SMS Inbox App',
      theme: ThemeData(
        primarySwatch: Colors.teal,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: const Text('SMS Inbox Example'),
        ),
        body: Container(
          padding: const EdgeInsets.all(10.0),
          child: _messages.isNotEmpty
              ? _MessagesListView(
                  messages: _messages,
                )
              : Center(
                  child: Text(
                    'No messages to show.\n Tap refresh button...',
                    style: Theme.of(context).textTheme.headline6,
                    textAlign: TextAlign.center,
                  ),
                ),
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: _querySmsMessages,
          child: const Icon(Icons.refresh),
        ),
      ),
    );
  }
}

class _MessagesListView extends StatelessWidget {
  const _MessagesListView({
    Key? key,
    required this.messages,
  }) : super(key: key);

  final List<SmsMessage> messages;

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      shrinkWrap: true,
      itemCount: messages.length,
      itemBuilder: (BuildContext context, int i) {
        var message = messages[i];

        return ListTile(
          title: Text('${message.sender} [${message.date}]'),
          subtitle: Text('${message.body}'),
        );
      },
    );
  }
}
