無法在Android中實例化活動ComponentInfo接收短信應用程序

Question

面對無法在啓動SMS Receiver應用程序時實例化活動ComponentInfo問題。任何能告訴我我在做什麼錯？

<?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> 

和類文件如下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(); 
    }       
} 
}

你的廣播接收器即ReceivesmsActivity和活性，即ReceivesmsActivity是同一個名字可能會造成問題，所以只是改變以不同的名稱註冊您的短信接收器：

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

並在代碼中創建一個類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  

} 
}
