Answer 1

I have nearly identical code that works fine, though I'm not opening a file from SD card in my app.

Activity mActivity = /* your activity */...;
String mFileName = /* path of my PDF file */...;

Uri uri  = Uri.fromFile(mActivity.getFileStreamPath(mFileName));

try
{
    Intent intentUrl = new Intent(Intent.ACTION_VIEW);
    intentUrl.setDataAndType(uri, "application/pdf");
    intentUrl.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    mActivity.startActivity(intentUrl);
}
catch (ActivityNotFoundException e)
{
    Toast.makeText(mActivity, "No PDF Viewer Installed", Toast.LENGTH_LONG).show();
}

so your approach is right on. Make sure you can open the file first ... i.e. use mActivity.openFileInput() to ensure you have a readable PDF.
