Proguard for android obfuscation

Question

Is there an easy way to handle this rather than changing the package name. Eg: I have the following 10 package names and I wish to obfuscate just one of them and keep rest of the other packages.

• com.myOrg.myApp.pkgNameA
• com.myOrg.myApp.pkgNameB
• com.myOrg.myApp.pkgNameC
• com.myOrg.myApp.pkgNameD
• com.myOrg.myApp.pkgNameE
• com.myOrg.myApp.pkgNameF
• com.myOrg.myApp.pkgNameG
• com.myOrg.myApp.pkgNameH
• com.myOrg.myApp.pkgNameI
• com.myOrg.myApp.pkgNameJ

I wish to obfuscate "com.myOrg.myApp.pkgNameA" and leave the other packages as is. I am presently listing down packages B-J in my proguard file to avoid obfuscating it. If I put "com.myOrg.myApp.**{*;}" this doesn't obfuscate "com.myOrg.myApp.pkgNameA" too.

Part of my proguard file:

-keep class com.myOrg.myApp.pkgNameB.** { *; }
-keep class com.myOrg.myApp.pkgNameC.** { *; }
-keep class com.myOrg.myApp.pkgNameD.** { *; }
-keep class com.myOrg.myApp.pkgNameE.** { *; }
-keep class com.myOrg.myApp.pkgNameF.** { *; }
-keep class com.myOrg.myApp.pkgNameG.** { *; }
-keep class com.myOrg.myApp.pkgNameH.** { *; }
-keep class com.myOrg.myApp.pkgNameI.** { *; }
-keep class com.myOrg.myApp.pkgNameJ.** { *; }

Is there any easy way to let proguard file know to keep all the packages except one which needs to be obfuscated?

Answer 1

can you use the negation operator on the class name?

-keep class !com.myOrg.myApp.pkgNameA.** { *; }
