proguard warning: the configuration keeps the entry point....but not the descriptor class

Question

I've configured:

-keep ,allowoptimization,allowobfuscation,allowshrinking public class     org.jf.dexlib2.dexbacked.** {     *; } 

but still getting the warning:

 Note: the configuration keeps the entry point 'com.trusteer.trf.dex_parser { int get_strings_count(org.jf.dexlib2.dexbacked.DexBackedDexFile); }', but not the descriptor class 'org.jf.dexlib2.dexbacked.DexBackedDexFile' 

I am using proguard version 4.7 (in Android SDK)

What should I do?

Answer 1

You have told Proguard to keep a certain method void foo(Bar bar); but to obfuscate the descriptor class Bar.

This is only a problem if you are going to invoke the method from an external source as the signature will be changed by the obfuscation (if you use Proguard to obfuscate a library and then use that library in another app).

So have the following choices:

• Configure Proguard to also keep Bar.

• Use the -dontnote directive to tell Proguard not to print notes like this.
