广播接收器接收不到下载完成动作 [英] BroadcastReceiver not receiving download complete action

问题描述

我试图捕捉到下载完成的事件，但我的广播接收器不接收他们。这里是接收器：

I am trying to capture download complete events, but my BroadcastReceiver is not receiving them. Here is the receiver:

public class DownloadListenerService extends BroadcastReceiver {        
    @Override
    public void onReceive(final Context context, Intent intent) {
        System.out.println("got here");
        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context);
        SharedPreferences.Editor editor = settings.edit();

        String action = intent.getAction();
        if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
            String downloadPath = intent.getStringExtra(DownloadManager.COLUMN_URI);
            editor.putString("downloadPath", downloadPath);
            editor.commit();
        }
    }
}

下面是明显的：

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

    <receiver 
        android:name="com.example.alreadydownloaded.DownloadListenerService" 
        android:exported="true">
        <intent-filter>
            <action android:enabled="true" android:name="android.intent.action.DOWNLOAD_COMPLETE" />
        </intent-filter>
    </receiver>
 </application>

你们看到了什么问题？

Anyone see what's wrong?

推荐答案

1），使用全包名称为您接收器如：com.example.DownloadListenerService

1-) use full package name for you receiver eg: com.example.DownloadListenerService

2-）添加机器人：出口=真正的广播接收器可以在其应用程序之外的接收源的邮件

2-) add android:exported="true" broadcast receiver can receive messages from sources outside its application

3）的意图过滤器改变动作的名称为android.intent.action.DOWNLOAD_COMPLETE

3-) change the name of the action in the intent filter to "android.intent.action.DOWNLOAD_COMPLETE"

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <receiver 
            android:name="com.example.DownloadListenerService"
            android:exported="true" >
            <intent-filter>
                <action android:name="android.intent.action.DOWNLOAD_COMPLETE" />
            </intent-filter>
        </receiver>
        <uses-permission android:name="android.permission.INTERNET" />
 </application>

您只收到广播请求是否来自您的应用程序，使应用程序运行在你里面这个code，看看是否接收器被触发

you only received broadcast if the request was from your app, so run this code inside you app and see if receiver is triggered

DownloadManager dm= (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse("https://www.google.com.tw/images/srpr/logo4w.png"));
dm.enqueue(request);
