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 .

Android signed APK generation : Proguard exception for referenced class / method not found

I need to generate a signed APK for Play Store. ( using Android Studio )
If I do that without proguard ( minifyEnabled false in build.gradle ) all works fine!
If I activate it with default parameters :
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
I receive these warnings

And the build process stop with this message :

After several tentatives I've found a way to remove the warnings with this lines in my "proguard-rules.pro" :
-dontwarn com.android.volley.**
-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
But the build process still goes in error!
Anyone have a workaround for this problem?
Thanks!
Davide

After several attemps ... here the solution :
First configure the dontwarn as suggested by Raymond ( maybe this is not necessary but i left it ) :
-dontwarn com.google.gson.**
-dontwarn java.nio.file.**
-dontwarn org.codehaus.mojo.animal_sniffer.**
-dontwarn com.squareup.okhttp.internal.huc.**
-dontwarn com.android.volley.error.**
Then configure Proguard to skip my library :
-keep class com.android.volley.error.** { *; }
-keep class com.squareup.okhttp.internal.huc.** { *; }
-keep class okio.** { *; }
Ather that the compilation was ok but on runtime the application crashed.
So, to avoid this problem, i've added these lines :
-keep class android.support.design.widget.** { *; }
-keep interface android.support.design.widget.** { *; }
-dontwarn android.support.design.**
based on some info found from this thread :
java.lang.RuntimeException: Could not inflate Behavior subclass
With this settings i'm able to generate a signed APK of my app.

You have to apply dontwarn to the referenced class instead.
For example:
-dontwarn com.google.gson.**
-dontwarn java.nio.file.**

Parse SDK Android Proguard issue

I have parse 1.5.1 in my app and everything works fine, but when I go to export to APK I get:
[2014-09-05 19:53:08 - myapp] Proguard returned with error code 1. See console

In my proguard.cfg I have the following:
-keepattributes *Annotation*
-keep class com.parse.* { *; }
-libraryjars libs/Parse-1.5.1.jar
This is driving me crazy!!!

You should try also keeping the subpackages of com.parse:
-keepattributes *Annotation*
-keep class com.parse.** { *; }
You should not add -libraryjars options, since the Android build process already automatically specifies all necessary -injars, -outjars, and -libraryjars for you. It only causes warnings about duplicate classes.

Mine was fixed by adding this:
-keep class com.parse.* { *; }
-dontwarn com.parse.**

Android app export with Pro guard giving errors

I don't know the OpenCSV library, but it looks like it was designed for standard Java. Android Java is the same programming language, but not the same runtime environment. I see references to java.awt.datatransfer.Transferable and java.beans.PropertyEditor in your error message. These classes don't exist on Android (full package list here). No amount of Proguard config is going to add them. You'll have to use a different CSV processing library, or at least, strip out and work around the parts of OpenCSV you can't use.

Arash is right
but you need to add more
try to add
-dontwarn com.google.android.gms.**
-dontwarn com.lnsur.kdbqq193162.**

Try adding :
-dontwarn com.google.android.gms.**
