Android - can't export apk with Proguard, when using Joda Time
android, jodatime, proguard
Solution
Ok I figured it out. Actually adding joda-convert.jar to build path works, but only for older version (1.4 and lower, if you download latest one - 1.5 joda-convert.jar, it doesn't work)...
Problem
I use joda-time.jar in my app, and when exporting signed apk proguard saying something like (it is pretty common problem as I can see, when I look over internet): ``` [2014-01-07 12:44:53 - XYZ] Proguard returned with error code 1. See console [2014-01-07 12:44:53 - XYZ] Warning: org.joda.time.DateMidnight: can't find referenced class org.joda.convert.FromString [2014-01-07 12:44:53 - XYZ] Warning: org.joda.time.DateTime: can't find referenced class org.joda.convert.FromString [2014-01-07 12:44:53 - XYZ] Warning: org.joda.time.Days: can't find referenced class org.joda.convert.FromString ...

But for me it just DOESN'T WORK, after I did it, proguard again says something similar: ``` [2014-01-07 12:41:39 - XYZ] Proguard returned with error code 1.

I spend few hours of trying everything, but I just can't find it out...Many thanks!
