Answer 1

You can do this if the other app responds to your intents. So instead of sending an explicit intent (Intent i = new Intent(this,TargetClass.class)) you would construct an intent that says “this is a PDF, anyone care to display it?”.

If the 3rd party app is installed and understands this, it will be presented in a selection box from where you can pick it.

The following example shows how to do this for sending email:

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_TEXT,text);
    String subject = getString(R.string.message_from_zwitscher);
    i.putExtra(Intent.EXTRA_SUBJECT, subject);

Have a look at the docs for Intent and the Intent and Filters guide. There is also a site Open Intents that is collecting information about usable intents.
