I think you should change your proguard rule like this.
http://frescolib.org/docs/proguard.html

And rule bellow is this proguard rule:

# Keep our interfaces so they can be used by other ProGuard rules.
# See http://sourceforge.net/p/proguard/bugs/466/
-keep,allowobfuscation @interface com.facebook.common.internal.DoNotStrip

# Do not strip any method/class that is annotated with @DoNotStrip
-keep @com.facebook.common.internal.DoNotStrip class *
-keepclassmembers class * {
    @com.facebook.common.internal.DoNotStrip *;
}

# Keep native methods
-keepclassmembers class * {
    native <methods>;
}

-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn com.android.volley.toolbox.**
