我正在使用广播接收器来拦截传入的消息。我已将意图数据从 OnReceive 方法传递给 WorkManager 类。我想从 pdu 中获取一个 SmsMessage，但是由于在 doWork 方法上接收到的数据是字符串，即使 pdu 对象也是一个字符串，因此很难从这样的 PDU 创建一个 SmsMessage 对象。下面是我的广播接收器代码；

      if (Telephony.Sms.Intents.SMS_RECEIVED_ACTION.equals(intent.getAction())) {
           final Bundle data = intent.getExtras();



            if (data != null){
                Data.Builder dataBuilder = new Data.Builder();
                for ( String key : data.keySet()){
                    dataBuilder.putString(key,String.valueOf(data.get(key)));
                    Log.d(TAG, "onReceive:  key:" +key+ " and keyValue "+data.get(key));
                }
                WorkManager mWorkManager = WorkManager.getInstance();
                OneTimeWorkRequest mRequest = new OneTimeWorkRequest
                        .Builder(MessageSyncWorker.class)
                        .setInputData(dataBuilder.build())
                        .build();
                mWorkManager.enqueue(mRequest);

                Log.d(TAG, "onReceive: Data: " +data);

            }

```


This is what am doing 
on the WorkManager class

```
public class MessageSyncWorker extends Worker {

    String sender, timestamp, msgID, text_message;
    private static final String TAG = "MessageSyncWorker";
    private static int counter = 0;
    public MessageSyncWorker(@NonNull Context context,
                             @NonNull WorkerParameters workerParams) {
        super(context, workerParams);
    }

    @NonNull
    @Override
    public Result doWork() {
        Data inputData = getInputData();
        Log.d(TAG, "doWork: " +" inputdata "+inputData +
                " DataValueMAP "+inputData.getKeyValueMap());

        Bundle extras = new Bundle();
        for (String key : inputData.getKeyValueMap().keySet()) {
//      extras.putString(key,String.valueOf(inputData.getString(key))); //This also works well
            extras.putString(key,inputData.getString(key));
            Log.d(TAG, "doWork: ExtrasKeySet " +extras.keySet());
            Log.d(TAG, "doWork: Extra Extra: "+inputData.getString(key));

        }
        Log.d(TAG, "doWork:  Extras: Tena "+extras);

        processBundleData(extras);

        return Result.success();
    }

    private void processBundleData (Bundle bundle){
        if (bundle !=null){
            Object[] newpdusObj = new Object[] {  bundle.get("pdus") };
            Log.d(TAG, "processBundleData: Bundle "+newpdusObj);
            if (newpdusObj !=null){
                for (int i = 0; i < newpdusObj.length; i++){
                    SmsMessage currentMessage =
                            SmsMessage.createFromPdu((byte[]) newpdusObj[i]);
                    Log.d(TAG, "processBundleData: CurrentSMS "+currentMessage);

                }
            }

        }

    }

```

Below is my logs showing the Exception,
