how to make intent.setType for pdf,xlsx and txt file android?

Question

I want to choose only pdf, xlsx and txt file from storage but intent.setType can do only one file(eg.txt file only (or) pdf file only). Is it possible to get all three files

Answer 1

The simple solution is

   Intent gallery=new Intent();
        gallery.setType("application/*");
        gallery.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(gallery,pick);

Note: pick is int variable.
