当在下载管理器中尝试查看CSV文件时，将收到Android意向过滤器通知

问题描述：

注册您的应用程序所需的魔咒是什么，当用户尝试查看他们以前通过下载管理器下载的CSV文件时收到通知.我玩了一段简短的视频，下面的过滤器将愉快地拦截由以下各项生成的通知:Dropbox，Box，Google Drive，Sky Drive，Chrome .....并提供打开文件的功能，但我的应用程序却收不到任何东西当用户尝试通过下载管理器查看文件时.

What's the required magic incantation to register your app to be notified that a user is trying to view a CSV file they've previously downloaded via the Download manager. I've had a brief play and the following filter will happily intercept notifications generated by: Dropbox, Box, Google Drive, Sky Drive, Chrome..... and offer itself to open the files, but my App isn't getting anything when a user attempts to view a file via the Download Manager. 

        <intent-filter>
            <action android:name="com.my.testImportApp.LAUNCH" />
            <action android:name="android.intent.action.SEND" />
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.EDIT" />
            <action android:name="android.intent.action.PASTE" />
            <action android:name="android.intent.action.OPEN_DOCUMENT" />
            <action android:name="android.intent.action.GET_CONTENT" />
            <action android:name="android.intent.action.INSERT" />
            <action android:name="android.intent.action.INSERT_OR_EDIT" />
            <action android:name="android.intent.action.SENDTO" />
            <action android:name="android.intent.action.SEND_MULTIPLE" />
            <action android:name="android.intent.action.PICK" />
            <category android:name="android.intent.category.CATEGORY_BROWSABLE" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.LAUNCHER" />
            <data android:scheme="http" />
            <data android:scheme="https" />
            <data android:scheme="ftp" />
            <data android:scheme="file" />
            <data android:scheme="data" />
            <data android:scheme="info" />
            <data android:scheme="data" />
            <data android:scheme="smb" />
            <data android:scheme="nfs" />
            <data android:scheme="android.resource" />
            <data android:mimeType="text/comma-separated-values"/>
            <data android:mimeType="text/csv"/>
            <data android:mimeType="text/plain"/>
        </intent-filter>

稍作播放后，以下内容似乎起作用:

After a bit of playing, the following appears to work:
