is it possible that you don't have an app to open this pdf file? Without an error message there could be a lot of reasons. — Stefan Lindner, Jan 13 '17 at 07:01
Thanks to everyone but I found the solition. The problem is that I use the version of android 6.0 +. In this version it is necessary to manually activate the permission to have access of recording by the program. Ex: settings-> app-> yourapp-> permissions. Thank you again to all the developer who gave their opinion. — Dos Argenté, Jan 14 '17 at 20:18

Here is code on how to open that file (test.pdf) with an Intent chooser:

File file = new File(getActivity().getFilesDir()+"/test.pdf");
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}

PdfRenderer support is added in Android 5.0

Below Android 5.0, you have to make a workaround
