Android intent filter: associate app with file ext

Question

I have a custom file type/extension that I want to associate my app with.

As far as I know, the data element is made for this purpose, but I can't get it working. http://developer.android.com/guide/topics/manifest/data-element.html According to the docs, and a lot of forum posts, it should work like this:

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:mimeType="application/pdf" />
</intent-filter>

Well, it does not work. What did I do wrong? I simply want to declare my own file type.

For Gmail attachment, you can use:

<intent-filter android:label="@string/app_name">
  <action android:name="android.intent.action.VIEW" />
  <category android:name="android.intent.category.DEFAULT" />
  <data android:scheme="content" />
  <data android:mimeType="application/pdf" /> <!-- .pdf -->
  <data android:mimeType="application/msword" /> <!-- .doc / .dot -->
  <data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" /> <!-- .docx -->
  <data android:mimeType="application/vnd.ms-excel" />  <!-- .xls / .xlt / .xla -->
  <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" />  <!-- .xlsx -->
  <data android:mimeType="application/vnd.ms-powerpoint" />  <!-- .ppt / .pps / .pot / .ppa -->
  <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" /> <!-- .pptx -->
  <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.slideshow" /> <!-- .ppsx -->
  <data android:mimeType="application/zip" /> <!-- .zip -->
  <data android:mimeType="image/jpeg" /> <!-- .jpeg -->
  <data android:mimeType="image/png" /> <!-- .png -->
  <data android:mimeType="image/gif" /> <!-- .gif -->
  <data android:mimeType="text/plain" /> <!-- .txt / .text / .log / .c / .c++ / ... -->

Add as many mime types as needed. I only need those for my project.
