Thank you in advance

Answer 1

The general guideline as to stacktraces is: READ THEM.
It is long and intimidating, but you don't have to understand each line. Most of them are just layers of method calls, some of the methods are written by you, some belong to the framework. It is perfectly all right if you can't recognize most of them. What you should do is just skim them, looking for:
lines that come from your code,
lines that have a "caused by..." clause on the beginning, especially the last one (because it is the root of all the problems).
You do not show your full stacktrace and we have to little data to help. But you can clearly see a java.lang.NoClassDefFoundError: org.jsoup.Jsoup. Which means that:
either there is a library missing from your application (how do you build it? are you sure it got added to the apk?),
or the class could not be loaded because of some other exceptions (look at the last one, it's usually the best clue).
WHEN you check it and still don't understand what has happened, it's probably best to ask another question, not change this one (because, for one, my answer will be out of place).
