Android 来自IntentService的registerReceiver不'；t命中广播接收机

我创建了一个

IntentService

，用于使用Android的DownloadManager下载文件。以下是我的班级：

public class DownloadService extends IntentService {

   public DownloadService() {
        super("name");
    }

    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            function();
         }
       };

    @Override
    protected void onHandleIntent(Intent intent) {
        registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
        Utility.download(someURL);

       }

    }

我在舱单中有此条目：

        <service
            android:name=".services.DownloadService"
            android:enabled="true" >
        </service>

BroadcastReceiver（function（））

中的代码永远不会执行，即使文件已下载。我也试着在

服务

中做同样的事情，而不是

IntentService

，它成功了。

如何使BroadcastReceiver在IntentService内部工作？

避免使用IntentService的上下文调用

registerReceiver

方法

方法返回后，将调用该方法。所有尚未注册的接收器都将被视为泄漏。该框架甚至警告您：

E/ActivityThread﹕ Service com.your.packagename.YourIntentService has leaked IntentReceiver com.your.packagename.YourReceiver@41f4cd08 that was originally registered here. Are you missing a call to unregisterReceiver()?

但是请注意，您必须添加逻辑，一旦完成注册，就会注销每个此类接收器实例。

我认为您需要在android清单中注册广播接收器，而不是通过编程进行设置。系统需要知道你的应用程序可以处理DownloadManager.ACTION\u DOWNLOAD\u COMPLETE Intents如果我希望注册的接收者在应用程序关闭后被触发，你会有什么建议。如果我使用getApplication context，它将不会被触发。@AraYeressian您可以在清单中声明您的接收器，并根据您的逻辑使用

getApplication().registerReceiver(receiverInstance,  
        new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
