Android - 短信广播接收器

Question

我一直试图让这个程序工作,但到目前为止没有运气.我无法找到我做错的地方.我不确定代码或调试是否有问题.

我正在尝试收到新短信到达时的通知.

这是我的计划:

package Technicaljar.SMSBroadcastReceiver;

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

public class SMSBroadcastReceiver extends BroadcastReceiver {

        private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
        private static final String TAG = "SMSBroadcastReceiver";

        @Override
        public void onReceive(Context context, Intent intent) {
             Log.i(TAG, "Intent recieved: " + intent.getAction());

                if (intent.getAction() == SMS_RECEIVED) {
                    Bundle bundle = intent.getExtras();
                    if (bundle != null) {
                        Object[] pdus = (Object[])bundle.get("pdus");
                        final SmsMessage[] messages = new SmsMessage[pdus.length];
                        for (int i = 0; i < pdus.length; i++) {
                            messages[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                        }
                        if (messages.length > -1) {
                            Log.i(TAG, "Message recieved: " + messages[0].getMessageBody());
                        }
                    }
                }
           }
    }

和清单文件:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="Technicaljar.SMSBroadcastReceiver"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" >
        <receiver android:name=".SMSBroadcastReceiver">
            <intent-filter>
                <action android:name="android.provider.telephony.SMS_RECEIVED"></action>
            </intent-filter>
        </receiver>

    </application>
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
</manifest> 

我通过Telnet发送短信,我在logcat中看不到任何Intent收到的消息.这是我安装时的logcat.

D/AndroidRuntime(  478): 
D/AndroidRuntime(  478): >>>>>>>>>>>>>> AndroidRuntime START <<<<<<<<<<<<<<
D/AndroidRuntime(  478): CheckJNI is ON
D/AndroidRuntime(  478): --- registering native functions ---

D/dalvikvm(  220): GC_EXPLICIT freed 926 objects / 44840 bytes in 73ms

所以短信似乎是由模拟器接收的,但看起来没有意图发射.我在这做错了什么？安装后,我是否必须以某种方式"启动"此接收器？因为当我安装时,我得到了

 [2010-11-07 21:24:41 - SMSBroadcastReceiver] No Launcher activity found!
[2010-11-07 21:24:41 - SMSBroadcastReceiver] The launch will only sync the application package on the device!

所以我想知道这里有什么问题.

Answer 1

android.provider.Telephony.SMS_RECEIVED有一个资本T,你的清单中没有.

请记住,此Intent操作未记录在案.

Answer 2

我尝试了你的代码,发现它无法正常工作.

我不得不改变

if (intent.getAction() == SMS_RECEIVED) {

至

if (intent.getAction().equals(SMS_RECEIVED)) {

现在它正在运作.这只是java检查相等性的问题.

Answer 3

另请注意,环聊应用程序目前会阻止我的BroadcastReceiver接收短信.在我的SMS BroadcastReceived开始被解雇之前,我不得不在环聊应用程序中禁用短信功能(设置 - >短信 - >打开短信).

编辑:似乎某些应用程序将在意图上abortBroadcast(),这将阻止其他应用程序接收意图.解决方案是增加标记中的android:priority属性intent-filter:

<receiver android:name="com.company.application.SMSBroadcastReceiver" >
  <intent-filter android:priority="500">
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
  </intent-filter>
</receiver>
