使用Proguard运行签名的APK时出错

Question

My app is crashing upon launching the signed apk version with Proguard enabled. Note that in regular debug mode, the app does not crash.

Now, if I were to guess I would say that Proguard is obfuscating a few classes that it shouldnt be. So how do you go about debugging this?

Here is my proguard-rules.pro :

-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int v(...);
    public static int i(...);
    public static int w(...);
    public static int d(...);
    public static int e(...);
}

# Retrofit 2.X

-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions

# Butterknife

}

So what might be causing this?

Apparently the issue was with JRAW , adding the following lines to my proguard-rules.pro file seems to have fixed the issue:

#jraw
-dontwarn net.dean.**
-keep class net.dean.** {*;}
