令牌上的语法错误，错误的构造？

Question

我正在尝试创建一个名为 broadcastMensajes 的类来扩展 BroadcastReceiver，我正在使用此处提供的代码：http://androidexample.com/Incomming_SMS_Broadcast_Receiver_-_Android_Example/index.php?view=article_discription&aid=62&aaid=87

Eclipse 几乎在所有代码下划线，并标注为"Syntax error on tokens, delete these tokens"。

"Syntax error on token(s), misplaced construct(s)"if 内的try

代码没问题，为什么会这样？

这是代码：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;

public class broadcastMensajes extends BroadcastReceiver {


    AccionesExecuter Ejecutor = new AccionesExecuter();
    final SmsManager smsManager = SmsManager.getDefault();
     
    @Override
    public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
        

        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();
 
        try {
             
            if (bundle != null) {
                 
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                 
                for (int i = 0; i < pdusObj.length; i++) {
                     
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                     
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                     
                } // end for loop
              } // bundle is null
 
        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" + e);
             
        }
    }    
}

添加所有支持的导入，例如：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;

public class BroadcastMensajes extends BroadcastReceiver {
    AccionesExecuter Ejecutor = new AccionesExecuter();
    final SmsManager smsManager = SmsManager.getDefault();

    @Override
    public void onReceive(Context context, Intent intent) {
        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();

        try {
            if (bundle != null) {
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                } // end for loop
              } // bundle is null
        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" + e);
        }
    }    
}
