title: Android select PDF using Intent on API 18
body: <p>I'm using following codes to select a PDF file using <code>Intent</code>. It perfectly works on Android 5.0+ but no suitable application to open a PDF file message appears on API 18.</p>
  
  <pre><code>public static Intent pickPdf() {
      Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
      intent.setType("application/pdf");
      intent.addCategory(Intent.CATEGORY_DEFAULT);
      return intent;
  }
  
  startActivityForResult(Intent.createChooser(pickPdf(), "Open with"), PICK_PDF);
  </code></pre>
