How to Proguard two android project？

Question

I have developed two projects in Andriod system based on java A and B , the codes in project A rely on codes in project B ,also the codes in project B rely on codes in project A.Can I use Proguard obfuscate A but not obfuscate B, A and B can also work well?

Answer 1

To prevent B from being obfuscated include something along the lines of:

-keep class com.projectB.package.** { *; }

for all the packages in project B. This goes in your proguard.cfg of any project that uses these files. When proguard runs, it will know to not obfuscate anything in B and project A will be obfuscated.
