Could not read ZoneInfoMap. You are probably using Proguard wrong.

Hi,

This is the stacktrace without any proguard rules

Using these rules solve the problem but I wonder what do you recommend

-dontwarn org.joda.convert.**
-dontwarn org.joda.time.**
-keep class org.joda.time.** { *; }
-keep interface org.joda.time.** { *; }
-keep class net.danlew.** { *; }

Hello. I faced the same problem. I solved this by adding only one rule -keep class net.danlew.android.joda.R$raw { *; }

Well, in particular, it looks like the minifier is removing the resource joda_zoneinfomap. That should be kept, as per our resource keep rules: https://github.com/dlew/joda-time-android/blob/master/library/src/main/res/raw/joda_keep.xml
