# Proguard Rules

{% hint style="info" %}
If you are using proguard to shrink and obfuscate your code, you must not obfuscate the custom classes you want to map using the SDK or it will result in empty objects of exceptions. 
{% endhint %}

To achieve that, you should add these lines to your proguard configuration file, replacing **`your.package.classname`** with your class full package name.

```java
–keep class your.package.classname
–keepclassmembers class your.package.classname { *; }
```

You may also need to add these lines to your proguard file:

```java
–dontwarn okhttp3.**
–dontwarn okio.**
–dontwarn javax.annotation.**
–dontwarn org.conscrypt.**
–keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase
```
