How to Make Proguard Ignore External Libraries

How to keep external libraries in proguard android

You need to use -keep to keep the class from any packages, something like:

-keep class io.crossbar.** { *; }

-dontwarn will only ignore the warnings. With, -keep you can keep any classes, class fields, and methods.

For more detailed usage check: ProGuard manual

Also, there is a feature request on GitHub for this repo to support ProGuard, here.

    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

How can I exclude external .jar from obfuscation by Proguard (Android project)?

If you don't want to edit the Ant script, you can add -keep options to proguard.cfg for the classes in those external jars. For instance:

-keep class othercode.** { *; }

Or with a regular expression containing a negator:

-keep class !mycode.** { *; }

The standard Ant script will still merge all referenced jars in the single output jar though.

How to exempt a library module from pro-guard in android gradle

The solution is to look up for the methods and classess that needs to be exempted and add them to the proguard rules as follows ( Here I needed to keep the files in classes com.mm.** and com.company.** where ** acts as wild char

-keep class com.mm.** {*;}
-keep class com.company.** {*;}
-keepclassmembers  class com.mm.** {*;}
-keepclassmembers  class com.company.** {*;}
