Error releasing APK using AsyncTask and Jsoup

I get this error:

With this piece of code:

 class Subscribe extends AsyncTask<String, Void, Result> { @Override protected Result doInBackground(String... s) { // ... Document test = Jsoup.parse("<html></html>"); // explodes here } }

This is only in release mode. I am using Jsoup 1.7.2. What's wrong? And as I can see, the errors crashed into "... 17 more," since I assume that the key lies there ...

This is the same question as the error using AsyncTask only when launching the release apk ... please help :( , but it does not answer.

This is cracking me!

This was a problem of obfuscation using ProGuard (which is logical if the problem exists only in release mode), I had to add the following to the proguard file:

 -keep public class org.jsoup.** { public *; }
