Small question about the download manager in android.
It&#39;s the first time I&#39;m working with it and have successfully downloaded multiple files and opened them. But my question is how do i check if the download completed.

The situation is I download a PDF file and open it, and usually the file is so small it complets before opening. But if the file is somewhat bigger how do I check if the download manager is finished with the download before opening it.

How I download: 

    Intent intent = getIntent();
    DownloadManager downloadManager = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
    Uri Download_Uri = Uri.parse(intent.getStringExtra(&quot;Document_href&quot;));
    DownloadManager.Request request = new DownloadManager.Request(Download_Uri);

    //Restrict the types of networks over which this download may proceed.
    request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
    //Set whether this download may proceed over a roaming connection.
    request.setAllowedOverRoaming(false);
    //Set the title of this download, to be displayed in notifications.
    request.setTitle(intent.getStringExtra(&quot;Document_title&quot;));
    //Set the local destination for the downloaded file to a path within the application&#39;s external files directory
    request.setDestinationInExternalFilesDir(this,Environment.DIRECTORY_DOWNLOADS,intent.getStringExtra(&quot;Document_title&quot;) + &quot;.pdf&quot;);
    //Enqueue a new download and same the referenceId
    Long downloadReference = downloadManager.enqueue(request);

How I open the file

    Uri uri = Uri.parse(&quot;content://com.app.applicationname/&quot; + &quot;/Download/&quot; + intent.getStringExtra(&quot;Document_title&quot;) + &quot;.pdf&quot;);
    Intent target = new Intent(Intent.ACTION_VIEW);
    target.setDataAndType(uri, &quot;application/pdf&quot;);
    target.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

    startActivity(target);

So somewhere between downloading and opening the file I want a if statement to check if it should continue or wait for the file.
