This fixed the problem for me: add those to the Proguard:

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.

Please, read warnings in console carefully. I`ve also faced with similar issue and in my case there were warnings about processing one of third party libraries. After applying corresponding changes related with the library to proguard file, all started to work correctly

I had this same issue. For me, my project's proguard file, namely, proguard-rules.pro, was somehow renamed to proguard-android.txt.

The proguard-android.txt is reserved for Android's default proguard rules, so essentially, I was overriding Android's proguard file, which was causing havoc, and I would get the Unable to compute hash message.

Once I changed the filename in my project from proguard-android.txt to proguard-rules.pro I was able to get things working.
