That's called an ANR ("Application Not Responding"). Something in the app is causing a hang. If
you wait long enough, Android should put up a dialog asking if you want to wait or close the
app. If you choose to wait, sometimes it comes back. However, the wait can be 10-20 seconds or
more so people often just quit before the dialog appears.
The problem here is figuring out what causes it. Is it always the same PDF file? Or maybe it
happens after opening a certain number of files, or the length of a file, or the cumulative
length of several files, or...? If it isn't reproducible, it's very difficult to find the cause.
If it happens to you at home some day, see if waiting 15 seconds or more puts up that dialog.
That would confirm it's an ANR.
