Most of your code looks right. Two things:

When you create the PDF file in your app’s local filesystem, you need to create it with the MODE_WORLD_READABLE flag. This is needed for the other application to be able to open the PDF.

Then use Uri.fromFile to get an Android URI to your file (you have this in commented code).

Note that MODE_WORLD_WRITEABLE is considered a poor security practice, because ANY app on the device will be able to access your PDF file. A better solution would be to create a ContentProvider and use a content: URI to serve the PDF data to the external application. This gives you control over whether to permit or deny access for any individual load of the PDF file (but it’s a bit more work).
