無法實例化接收器

發送意圖到我的應用程序時出現「無法實例化接收器」錯誤。看來Eclipse似乎無法看到我的ExIntentReceiver類。我不知道爲什麼會發生。 ExIntentReceiver位於同一個包（com.example.app）中。無法實例化接收器

ExIntentReceiver.java：

package com.example.app 

public class ExIntentReceiver extends BroadcastReceiver { 

@Override 
    public void onReceive(Context context, Intent intent) { 
     String action = intent.getAction(); 
    if(action.equals("com.example.app.START_SERVICE")) { 
     Log.v("service", "is started"); 
     } else if(action.equals("com.example.app.STOP_SERVICE")) { 
      Log.v("service", "is stopped"); 
     } 

    } 
}

清單：

<receiver android:name=".ExIntentReceiver" android:exported="true"> 
     <intent-filter> 
    <action android:name="com.example.app.START_SERVICE" /> 
     <action android:name="com.example.app.STOP_SERVICE" /> 
    </intent-filter> 
    </receiver>

的logcat：

類是'ExtIntentReceiver'but在你的清單文件'ExIntentReceiver'。 – rciovati 2013-04-22 09:12:07

你應該在自己的意圖過濾器已經行動聲明。

<receiver android:name=".ExtIntentReceiver " android:exported="true"> 
    <intent-filter> 
     <action android:name="com.example.app.START_SERVICE" /> 
    </intent-filter> 
    <intent-filter> 
     <action android:name="com.example.app.STOP_SERVICE" /> 
    </intent-filter> 
</receiver>

除此之外確保你Receiver給出正確的包名內明顯。並確保你應該拼寫正確。

如果你想有廣播接收器的內部類，你想用它未做它的實例你應該讓STATIC這樣

public static class MyBroadcastReceiver extends BroadcastReceiver 
{ 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     //do what you want 
    } 
}
