Thank you a lot for posts like this that help us to advance step by step.
I’ve came up with other solution after i have tried the last one without success:
# OrmLite uses reflection
-keep class com.j256.**
-keepclassmembers class com.j256.** { *; }
-keep enum com.j256.**
-keepclassmembers enum com.j256.** { *; }
-keep interface com.j256.**
-keepclassmembers interface com.j256.** { *; }
I hope it can help someone.
