Question

启动SMS Receiver应用程序时，无法实现活动ComponentInfo问题。可以告诉我我做错了什么????

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.raja.receivesms"
  android:versionCode="1"
  android:versionName="1.0.0">
<application android:icon="@drawable/ic_launcher" android:label="@string/app_name">
    <activity android:name=".ReceivesmsActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".ReceivesmsActivity"> 
        <intent-filter> 
            <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
        </intent-filter> 
    </receiver>
</application>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<uses-sdk android:minSdkVersion="8" /></manifest>

类文件如下：ReceivesmsActivity.java

    package com.raja.receivesms;
import android.content.*;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;
import android.content.Intent;

public class ReceivesmsActivity extends BroadcastReceiver {

 private static final String TAG = "Message recieved";

 @Override
 public void onReceive(Context context, Intent intent) {    
     Bundle bundle = intent.getExtras();        
     SmsMessage[] msgs = null;
     String str = "";            
     if (bundle != null)
     {
         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]);                
             str += "SMS from " + msgs[i].getOriginatingAddress();                     
             str += " :";
             str += msgs[i].getMessageBody().toString();
             str += "\n";        
         }
         Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
     }                         
 }
 }

您的BroadcastReceiver即Receivesms活动和活动，即Receivesms活动具有相同的名称可能会导致问题因此只需更改为不同的名称注册您的短信接收器为：

<receiver android:name=".ReceivesmsBroadcast"> 
        <intent-filter> 
            <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
        </intent-filter> 
    </receiver>

并在代码中创建一个类ReceivesmsBroadcast.java：

public class ReceivesmsBroadcast extends BroadcastReceiver {

 private static final String TAG = "Message recieved";

 @Override
 public void onReceive(Context context, Intent intent) {    
///     your code go here      

 }
 }

无法在Android接收Sms应用程序中实例化活动ComponentInfo
