Question

我已经搜索了几个小时，发现了类似的问题并尝试了这些解决方案，但到目前为止还没有任何工作。我正在使用Android工作室与运行Android版本23的模拟器。我怀疑我的问题是在某个地方有SMS_RECEIVE的权限，因为我的其他操作正在触发我的接收器的行为。这是我的清单：

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <receiver android:name=".SmsMonitor" android:exported="true" android:permission="android.permission.BROADCAST_SMS" >
        <intent-filter android:priority="999" >
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            <action android:name="myAction.updateKeyword" />
            <action android:name="myAction.closeApp" />
    </intent-filter>
    </receiver>

</application>

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

这是我的接收器的代码：

package com.example.the_f.smsalert;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.TaskStackBuilder;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Vibrator;
import android.support.v7.app.NotificationCompat;
import android.telephony.SmsMessage;

import static android.R.drawable.stat_notify_more;

/**

public class SmsMonitor extends BroadcastReceiver {

public static final String SMS_BUNDLE = "pdus";
private final String UPDATE_KEYWORD = "myAction.updateKeyword";
private final String CLOSE_APP = "myAction.closeApp";
private final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
private Context context;

@Override
public void onReceive(Context context, Intent intent) {
    this.context = context;
    String action = intent.getAction();
    System.out.println("action is: " + action);

    //only want to inspect the message if the app is active
    if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
        System.out.println("the action was sms received");
        Bundle extras = intent.getExtras();
        if(extras != null){
            Object[] messages = (Object[]) extras.get(SMS_BUNDLE);
            String messageContent = "";
            for(int i = 0; i < messages.length; i++){
                SmsMessage msg = SmsMessage.createFromPdu((byte[]) messages[i]);
                messageContent = msg.getMessageBody().toString();
            }

            System.out.println("build sms message: " + messageContent);
            inspectForKeyword(messageContent.toLowerCase());
    }

    //update the keyword for the app. also sets the receiver to active to start monitoring
    }else if(action.equals(UPDATE_KEYWORD)){
        keyword = intent.getStringExtra("keyword").toLowerCase();
        active = true;
        System.out.println("changing keyword to: " + keyword);
        testAlarm();

        //the main activity was closed and so this receiver should stop monitoring
    }else if(action.equals(CLOSE_APP)){
        System.out.println("setting smsMonitor in inactive");
        active = false;

    }else{
        //not a valid intent for this receiver. shouldnt get here.
    }


}

private void inspectForKeyword(String messageContent) {
    if (messageContent.contains(keyword)) {
        //activate vibrate

        //activate ringer

        //activate led flash

        //send notification

    }
}

private void testAlarm(){
    //binds an activity to start when the notification is clicked
    Intent smsIntent = new Intent(Intent.ACTION_MAIN);
    smsIntent.setType("android.intent.category.APP_MESSAGING");
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0 , smsIntent, 0);

    //builds the notification
    NotificationCompat.Builder notifBuilder = new NotificationCompat.Builder(context);
    notifBuilder.setSmallIcon(stat_notify_more);
    notifBuilder.setContentTitle("You have an Emergency Alert!");
    notifBuilder.setContentText("Check your messages for an Emergency!");
    notifBuilder.setContentIntent(pendingIntent);
    //sends notification
    NotificationManager notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    notifManager.notify(0, notifBuilder.build());

    Vibrator vibes = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    vibes.vibrate(3000);


}

}

大多数java代码都可以忽略。我有一堆我试图测试的代码。但是，在onReceive（）的顶部，我有一个print语句来打印操作的名称。当我使用其他两个动作时，print语句会触发，但是当我使用模拟器并模拟接收文本时，则不会触发。模拟器的消息传递应用程序指示它在我模拟发送短信时收到消息，但我的广播接收器没有得到通知。我真的可以使用一些帮助。我对我的问题一无所知。

Broadcastreceiver短信听众不工作
