读取电话状态广播没有被调用

Question

我正在尝试听手机状态。我在我的清单文件中注册了接收器。但接收器没有被调用。 收到广播后，我想听电话状态并开始服务。

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

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <receiver android:name=".ConnectvityMonitor" >
            <intent-filter>
                <!--<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />-->
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>
        <activity
            android:name=".NetWorkMonitorActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是我的接收器

package com.example.networkmonitor;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;


public class ConnectvityMonitor extends BroadcastReceiver {


    @Override
    public void onReceive(Context context, Intent intent) {

        String state="";



            Log.d("BroadCast Fired","BroadCast Fired");

            Toast.makeText(context,"BroadCast",Toast.LENGTH_SHORT).show();

    }



}
