Answer 2

Using Maven in my case, google-api-client brought guava-jdk5 as a dependency, causing similar problems.

Guava wiki page on Proguard suggests: https://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue

Add these line in your proguard-project.txt

-keep public class com.google.common.**
-keep public class * extends android.app.Activity
