Natty crashes on signed builds

[azurh]

The Natty parser works well on debug builds, but crashes on signed ones.

It worked perfectly a year ago. Now, I tried many possible combinations for including this library in my app (Maven, local .jar etc.)

I finally have managed to include Natty in my app. I went to the Maven repository, searched for Natty, and then downloaded all the jar dependencies (which are listed).

Now my dependencies look like this:

// natty
compile files('libs/natty/ical4j-2.0.0.jar')
compile files('libs/natty/antlr-runtime-3.5.2.jar')
compile files('libs/natty/natty-0.12.jar')
compile files('libs/natty/slf4j-android-1.7.22.jar')
compile files('libs/natty/slf4j-api-1.7.22.jar')
