Question

我在调试时遇到问题。这是我的情景：

我正在使用android studio。我转而使用appcompat-v7库。不幸的是，我只能访问受this issue影响的运行4.2.2（运气不好）的三星设备。我使用proguard提供的临时解决方案，在我的proguard文件中应用以下行。

-keep class !android.support.v7.internal.view.menu.**,android.support.** {*;}
-dontwarn retrofit.appengine.*
-dontwarn retrofit.client.OkClient
-dontwarn rx.internal.util.unsafe.*

使用上述行是因为我收到了此类错误，而这是我提供的解决方法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

如果我运行一个简单的＆＃34; Hello World＆＃34;在我没有使用改造来获取数据的应用程序中，我能够使用此proguard解决方法在我的Samsung 4.2.2设备的屏幕上获取ActionBarActivity。但是，当我运行使用改造的应用程序时，我得到以下堆栈跟踪。

我正在使用retrofit-1.8.0.jar和com.android.support:appcompat-v7:21.0.3

对此的任何见解都将非常感激。在此之前，我将避免使用appcompat库进行测试。
