Some questions:
1) since you say the file does not open, I assume you are landing in
the catch{} clause with an exception. What exception do you get?
2) what Activity do you have registered for
android.content.Intent.ACTION_VIEW in AndroidManifest.xml?
3) How did you arrive at the conclusion that filePath + "/" +
label.getText() was the right way to build the file name? That looks
like path + extension w/ everything in between missing.
