How to prevent an entire class from be modified by proguard?

Question

I need to keep com.package.app.helpers.GraphAdapterBuilder class

I tried with:

-keep class com.package.app.helpers.GraphAdapterBuilder

and

-keep class com.package.app.helpers.GraphAdapterBuilder.** { *; }

But it seems that it's not working. What is wrong?

Answer 1

Try:

-keep class com.package.app.helpers.GraphAdapterBuilder { *; }

If GraphAdapterBuilder is only the one class in the package you also may try:

-keep class com.package.app.helpers.** { *; }
