Q:

Error when exporting app that used Proguard

I try to use Proguard in my app.  I wrote this code in proguard.cfg file:
    -optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations ! code/simplification/arithmetic,!field/*,!class/merging/*
-keep public class * extends android.app. Activity
-keep public class * extends android.app. Application
-keep public class * extends android.app. Service
-keep public class * extends android.content. BroadcastReceiver
-keep public class * extends android.content. ContentProvider
-keep public class   Mp4ParserWrapper.** { *; } 
-keep public class com.android.vending.licensing. ILicensingService
-keepclasseswithmembernames class * {
    native <methods>;
}
-keepclasseswithmembernames class * {
    public <init>(android.content. Context, android.util. AttributeSet);
}
-keepclasseswithmembernames class * {
    public <init>(android.content. Context, android.util. AttributeSet, int);
}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang. String);
}
-keep class * implements android.os. Parcelable {
  public static final android.os. Parcelable$Creator *;
}

When export app get can't find referenced class error .I search on the internet and add this line -keep public class   Mp4ParserWrapper. { *; }**  to proguard file but don't solve problem .
