I'm having trouble debugging this. Here's my scenario:
I'm using android studio. I'm switching to use the appcompat-v7 library. Unfortunately I only have access to Samsung devices running 4.2.2 (bad luck) which are affected by this issue. I'm using the temporary solution provided with proguard, applying the following lines in my proguard file.
-keep class !android.support.v7.internal.view.menu.**,android.support.** {*;}
-dontwarn retrofit.appengine.*
-dontwarn retrofit.client.OkClient
-dontwarn rx.internal.util.unsafe.*
The above lines are used because I'm getting error of this sort, and this was the workaround provided here
Warning: retrofit.appengine.UrlFetchClient: can't find referenced class com.google.appengine.api.urlfetch.HTTPMethod
Warning: retrofit.client.OkClient: can't find referenced class com.squareup.okhttp.OkHttpClient
Warning: rx.internal.util.unsafe.ConcurrentCircularArrayQueue: can't find referenced class sun.misc.Unsafe
If I run a simple "Hello World" application where I'm not using retrofit to fetch data, I'm able to get the ActionBarActivity on a screen of my Samsung 4.2.2 device using this proguard workaround. However, when I run my application that uses retrofit I get the following stack trace.
I'm using retrofit-1.8.0.jar and com.android.support:appcompat-v7:21.0.3
Any insight into this would be much appreciated. Until then, I'll just avoid using the appcompat libraries for testing purposes.
