检测传入的 SMS 消息

Detecting incoming SMS messages

在我的 android 代码中,我正在尝试检测传入的 SMS 消息。下面的代码工作了 2 年,但现在停止工作了。我缺少哪些更新?

public class SmsListener extends BroadcastReceiver {

    private String msgBody;
    private SharedPreferences preferences;

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub


        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){

            Toast.makeText(context,"message received",Toast.LENGTH_SHORT).show();

            Bundle bundle = intent.getExtras();           //---get the SMS message passed in---
            SmsMessage[] msgs = null;
            String msg_from;
            if (bundle != null){
                //---retrieve the SMS message received---
                try{
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    msgs = new SmsMessage[pdus.length];
                    for(int i=0; i<msgs.length; i++){
                        msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                        msg_from = msgs[i].getOriginatingAddress();
                        msgBody = msgs[i].getMessageBody();
                        MainActivity.handleMessage(msgBody);
                    }

                    Toast.makeText(context,"message is:"+msgBody,Toast.LENGTH_SHORT).show();
                }catch(Exception e){
                    Log.d("Exception caught",e.getMessage());
                }
            }
        }
    }

在我的 Main Activity 中,我正在请求用户许可,并按如下方式使用 SMS 接收器:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



//Updated///////////////////////////////////////////////////////////////////////////////////
           if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
            requestSmsPermission();
        else {
            smsListener = new SmsListener();
            IntentFilter intentFilter = new IntentFilter();
            intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
            registerReceiver(smsListener, intentFilter);
        }

        ///////Updated///////////////////////////////////////////////////////////////////////////////////

    }


private void requestSmsPermission() {
    String permission = Manifest.permission.RECEIVE_SMS;
    int grant = ContextCompat.checkSelfPermission(this, permission);
    if ( grant != PackageManager.PERMISSION_GRANTED) {
        String[] permission_list = new String[1];
        permission_list[0] = permission;
        ActivityCompat.requestPermissions(this, permission_list, 1);

    }
}

  @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 1) {
            smsListener = new SmsListener();
            IntentFilter intentFilter = new IntentFilter();
            intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
            registerReceiver(smsListener, intentFilter);
        }
    }

我的Manifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.zaidalmahmoud.expenseless">

            </intent-filter>
        </receiver>

        <activity android:name=".DetailedExpenseActivity" />
    </application>

</manifest>

收到短信后,我的 android 应用程序没有检测到它,但它没有崩溃或显示任何内容。为什么?谢谢

注意:我对抓取验证码短信不感兴趣。我希望我的应用程序能够捕获任何传入的短信。

Android 应用程序需要 SMS receive/read 权限才能检索 SMS 内容。 Google 引入了 SMS Retriever API,此 API 允许在您的应用程序中无需 SMS 权限即可检索 OTP。

为 SMS 检索器添加这些依赖项 API

implementation 'com.google.android.gms:play-services-base:16.0.1'
implementation 'com.google.android.gms:play-services-identity:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'com.google.android.gms:play-services-auth-api-phone:16.0.0'

然后创建如下界面:

public interface OnNewMessageListener {
    void onNewMessageReceived(String activationCode);
}

然后,创建一个 broadCastReceiver 来接收短信:

public class SmsBroadcastReceiver extends BroadcastReceiver {
    OnNewMessageListener onNewMessageListener;

    public SmsBroadcastReceiver() {
    }

    public SmsBroadcastReceiver(OnNewMessageListener onNewMessageListener) {
        this.onNewMessageListener = onNewMessageListener;
    }

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

                if (status != null)
                    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.
                            if (!TextUtils.isEmpty(message)) {
                                String activationCode = null;
                                Pattern p = Pattern.compile("your pattern like \b\d{4}\b");
                                Matcher m = p.matcher(message);
                                if (m.find()) {
                                    activationCode = (m.group(0));  // The matched substring
                                }

                                if (onNewMessageListener != null && !TextUtils.isEmpty(activationCode))
                                    onNewMessageListener.onNewMessageReceived(activationCode);
                            }
                            break;
                        case CommonStatusCodes.TIMEOUT:
                            // Waiting for SMS timed out (5 minutes)
                            // Handle the error ...
                            break;
                    }
            }
        }
    }
}

在你的 AndroidManifest 声明 broadcastReceiver:

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

在您的 activity 中添加这些代码:

    private SmsBroadcastReceiver smsListener;

     @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    // Get an instance of SmsRetrieverClient, used to start listening for a matching
            // SMS message.
            SmsRetrieverClient client = SmsRetriever.getClient(Objects.requireNonNull(getContext()) /* context */);

            // Starts SmsRetriever, which waits for ONE matching SMS message until timeout
            // (5 minutes). The matching SMS message will be sent via a Broadcast Intent with
            // action SmsRetriever#SMS_RETRIEVED_ACTION.
            Task<Void> task = client.startSmsRetriever();

            // Listen for success/failure of the start Task. If in a background thread, this
            // can be made blocking using Tasks.await(task, [timeout]);
            task.addOnSuccessListener(aVoid -> {
                // Successfully started retriever, expect broadcast intent
                // ...
            });

            task.addOnFailureListener(e -> {
                // Failed to start retriever, inspect Exception for more details
                // ...
            });

            OnNewMessageListener onNewMessageListener = activationCode -> {
                if (!TextUtils.isEmpty(activationCode)) {
                    editText.setText(String.valueOf(activationCode));
                }
            };
            smsListener = new SmsBroadcastReceiver(onNewMessageListener);
            if (getContext() != null)
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    getContext().registerReceiver(smsListener, new IntentFilter(SmsRetriever.SMS_RETRIEVED_ACTION));
                }
    }

    @Override
    public void onStop() {
        super.onStop();
        try {
            if (getContext() != null && smsListener != null) {
                getContext().unregisterReceiver(smsListener);
                smsListener = null;
            }
        } catch (Exception ignored) {
        }
    }

你的短信应该是这样的:

将您的 BroadcastReceiver 更改为:

public class SmsListener extends BroadcastReceiver {

    private String msgBody;
    private SharedPreferences preferences;

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub


        if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {

            Toast.makeText(context, "message received", Toast.LENGTH_SHORT).show();

            Bundle bundle = intent.getExtras();
            try {
                if (bundle != null) {
                    final Object[] pdus = (Object[]) bundle.get("pdus");
                    for (int i = 0; i < pdus.length; i++) {
                        SmsMessage smsMessage;
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
                            smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i], bundle.getString("format"));
                        else smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);

                        msg_from = smsMessage.getDisplayOriginatingAddress();
                        msgBody = smsMessage.getMessageBody();
                        MainActivity.handleMessage(msgBody);
                    }
                    Toast.makeText(context, "message is:" + msgBody, Toast.LENGTH_SHORT).show();
                }
            } catch (Exception e) {
                Log.d("Exception caught", e.getMessage());
            }
        }
    }
}

在您的 android 清单文件中声明 SMS 读取和接收权限:

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

那么我们需要一个短信接收器如下:

class SMSReceiver : BroadcastReceiver() {

override fun onReceive(context: Context, intent: Intent?) {
    if (intent != null && intent.action != null && intent.action!!.equals("android.provider.Telephony.SMS_RECEIVED", ignoreCase = true)) {
        val bundle = intent.extras
        if (bundle != null) {
            val sms = bundle.get(SMS_BUNDLE) as Array<Any>?
            val smsMsg = StringBuilder()

            var smsMessage: SmsMessage
            if (sms != null) {
                for (sm in sms) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        val format = bundle.getString("format")
                        smsMessage = SmsMessage.createFromPdu(sm as ByteArray, format)
                    } else {
                        smsMessage = SmsMessage.createFromPdu(sm as ByteArray)
                    }


                    val msgBody = smsMessage.messageBody.toString()
                    val msgAddress = smsMessage.originatingAddress

                    smsMsg.append("SMS from : ").append(msgAddress).append("\n")
                    smsMsg.append(msgBody).append("\n")
                }

                sendBroadcast(smsMsg.toString())
            }
        }
    }
}

private fun sendBroadcast(smsMSG: String) {
    val broadcastIntent = Intent()
    broadcastIntent.action = AppConstants.mBroadcastSMSUpdateAction
    broadcastIntent.putExtra(AppConstants.message, smsMSG)
    EventBus.getDefault().post(EventIntent(broadcastIntent))
}

companion object {

    val SMS_BUNDLE = "pdus"
}
}

您可以将收到的短信信息广播到您的MainActivity。

然后您需要在清单文件中声明短信广播接收器,如下所示:

  <receiver
        android:name=".SMSReceiver"
        android:enabled="true">
        <intent-filter android:priority="2147483647">
            <category android:name="android.intent.category.DEFAULT" />

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

在 MainActivity 中启动应用程序后,您需要通过以下方式检查 SMS 权限:

Manifest.permission.READ_SMS,
Manifest.permission.RECEIVE_SMS

您可以使用内置的 android 权限模块或 RxPermission :

  val rxPermissions = RxPermissions(this)
    rxPermissions.request(
            Manifest.permission.READ_SMS,
            Manifest.permission.RECEIVE_SMS)
            .subscribe(object : Observer<Boolean> {
                override fun onNext(t: Boolean) {
                    if (t) {

                    } else {
                        Toast.makeText(activity, getString(R.string.permission_request_denied), Toast.LENGTH_LONG).show()
                    }
                }
                override fun onSubscribe(d: Disposable) {}
                override fun onError(e: Throwable) {}
                override fun onComplete() {}
            })
