如何从广播接收器推出下载管理器？ [英] How to launch download manager from Broadcast Receiver?

问题描述

我的应用程序下载较大的zip文件（100MB +）。我使用的是默认的下载管理器，方便下载。在谷歌的API文档建议注册一个BroadcastReceiver，并听取了ACTION_NOTIFICATION_CLICKED。我这样做，但我不知道如何从的BroadcastReceiver中调用下载管理器。

我想要做的基本上是浏览器一样。当浏览器下载的文件，并在用户点击了下载管理通知的下载管理窗口弹出。我用什么意图做到这一点？

我的code：

 ＆LT;接收器的Andr​​oid版本：NAME =com.test.receiver.DownloadReceiver＆GT;
  ＆LT;意向滤光器＆gt;
     ＆lt;作用机器人：名称=android.intent.action.DOWNLOAD_COMPLETE＆GT;＆LT; /作用＆gt;
     ＆lt;作用机器人：名称=android.intent.action.DOWNLOAD_NOTIFICATION_CLICKED/＆GT;
  ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;

公共类DownloadReceiver扩展的BroadcastReceiver {

私有静态最后字符串变量= DownloadReceiver.class.getSimpleName（）;

@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
    串动= intent.getAction（）;
    如果（DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals（动作））{
    *** $ C $下解压删除***
    }
    否则如果（DownloadManager.ACTION_NOTIFICATION_CLICKED.equals（动作））{
        //打开的下载管理器
        //但如何???

    }
 

解决方案

找到我自己的答案。这是卓有成效的。

 意图DM =新的意图（DownloadManager.ACTION_VIEW_DOWNLOADS）;
dm.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
context.startActivity（DM）;
 

My application downloads large zip files (100mb+). I'm using the default DownloadManager to facilitate the download. The Google API docs suggest to register a BroadcastReceiver and listen for ACTION_NOTIFICATION_CLICKED. I'm doing that, but I have no clue how to call the DownloadManager from within the BroadcastReceiver.

What I want to do is basically what the browser does. When the browser downloads a file and the user clicks on the DownloadManager notification the DownloadManager window pops up. What intent do I use to accomplish this?

My Code:

<receiver android:name="com.test.receiver.DownloadReceiver">
  <intent-filter>
     <action android:name="android.intent.action.DOWNLOAD_COMPLETE"></action>
     <action android:name="android.intent.action.DOWNLOAD_NOTIFICATION_CLICKED" />
  </intent-filter>
</receiver>

public class DownloadReceiver extends BroadcastReceiver {

private static final String tag = DownloadReceiver.class.getSimpleName();

@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
    *** code for unzipping removed ***
    }
    else if (DownloadManager.ACTION_NOTIFICATION_CLICKED.equals(action)) {
        // Open the download manager
        // BUT HOW???

    }

解决方案

Found my own answer. This does the trick.

Intent dm = new Intent(DownloadManager.ACTION_VIEW_DOWNLOADS);
dm.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(dm);
