title: Android app crashes while trying to open file from Downloads
body: <p>I am new to android and I am trying to download a pdf file using URL link. The file is downloaded in Downloads directory and the file exists in the directory after the download operation is completed. If I try to open the pdf file using intent the app is crashing, I am quite aware that the URI which I pass to the <code>Intent.setDataAndType()</code> is wrong. How to get the correct URI for the downloaded file.</p>
  
  <p>Here is my code.</p>
  
  <pre><code>String url = "https://…";
  DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
  
  request.setDescription("Some descrition");
  
  request.setTitle("Some title");
  
  if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB) {
      request.allowScanningByMediaScanner();
      request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
  }
  request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "name-of-the-file.pdf");
  
  DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
  manager.enqueue(request);
  
  File file = new File(getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS) + "/name-of-the-file.pdf");
  
  Uri uri = Uri.fromFile(file);
  Intent intent = new Intent(Intent.ACTION_VIEW);
  intent.setDataAndType(uri, "application/pdf");
  context.startActivity(intent);
  </code></pre>
  
  <p>I am somewhere messing with the path passed to the intent. Any kind of help is appreciable. Thanks in advance.</p>
