Android:活动未从后台执行onNewIntent（）（从服务调用）

这是我的第一个Android程序。我有一个活动可以大声读取信息，一个接收器可以监听收到的短信，还有一个服务可以让应用程序在后台工作

我的主要活动有一个切换按钮。启用时，它将启动服务，该服务将创建一个通知，以防止应用程序被终止。用户还可以单击通知返回到主活动：

package com.rockmanx77777.SMSbyVoice;
import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.graphics.BitmapFactory;
import android.os.Binder;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

public class SMSService extends Service{

    @Override
    public void onCreate() {
        createNotification();
        super.onCreate();
    }

    public class MyBinder extends Binder {
        SMSService getService() {
            return SMSService.this;
        }
    }

    private final IBinder binder = new MyBinder();

    @Override
    public IBinder onBind(Intent intent) {
        return binder;
    }

    private void createNotification(){

        final int NOTIFICATION_ID = 77777;
        Intent intent = new Intent(this, SMSByVoice.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra("senderNumber", "");
        intent.setAction("com.rockmanx77777.SMSByVoice.PROCESS");
        PendingIntent pi = PendingIntent.getActivity(this, 1, intent, 0);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

        builder.setContentTitle("Sample Title");
        builder.setContentText("Sample Text");
        builder.setSmallIcon(R.drawable.ic_launcher);
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher));
        builder.setContentIntent(pi);

        Notification notification = builder.getNotification();
        notification.flags = notification.flags | Notification.FLAG_ONGOING_EVENT;

        startForeground(NOTIFICATION_ID, notification);
    }
}

当有传入SMS时，正确调用服务的onReceive。执行所有操作，包括

context.startActivity（localSMS）就是在这里我遇到了问题：

public class SMSReceiver extends BroadcastReceiver{

    public SMSReceiver(){
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("MSG", "Receiver's onReceived Called");
        if(intent.getAction() == "android.provider.Telephony.SMS_RECEIVED"){
            //Get the SMS message passed in
            Bundle bundle = intent.getExtras();        
            SmsMessage[] msgs = null;
            String senderNumber = "";
            String body = "";
            if (bundle != null){
                //Retrieve the SMS message received
                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]);  
                    body = msgs[i].getMessageBody().toString();    
                }
                senderNumber = msgs[0].getOriginatingAddress();

                Intent localSMS = new Intent(context, SMSByVoice.class);
                localSMS.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                localSMS.setAction("rockmanx77777.SMSByVoice.RETURN");
                localSMS.putExtra("senderNumber", senderNumber);
                localSMS.putExtra("body", body);
                Log.d("MSG", "Starting activity from Receiver");
                context.startActivity(localSMS);
            }
        }
        else{
            Log.d("MSG", "intent.getAction() != android.provider.Telephony.SMS_RECEIVED");
        }
    }
}

@凌驾
公共void onReceive（上下文、意图）{
Log.d（“MSG”，“收到呼叫的接收器”）；
if（intent.getAction（）=“android.provider.Telephony.SMS_RECEIVED”）{
//获取传入的SMS消息
Bundle=intent.getExtras（）；

对于（int i=0；i我找出了缺少的内容。我的服务中没有接收器：我的服务类更改为：

public class SMSService extends Service{

    SMSReceiver receiver = new SMSReceiver();

    @Override
    public void onCreate() {
        Log.d("MSG", "SMSService OnCreate Started");

        createNotification();

        super.onCreate();
        Log.d("MSG", "SMSService OnCreate Ended");
    }

    public class MyBinder extends Binder {...
