Android proguard issues for release

Question

I\'m able to create builds for my android app, but when I turn on proguard i\'m getting numerouos warnings, and then the build fails. The warnings are like the ones below:

Answer 1

Your libraries contain duplicates of the android.http classes, which are already present in the Android runtime. This may cause conflicts. You should remove the duplicate libraries from your project.

See the ProGuard manual > Troubleshooting > Warning: library class ... depends on program class ...

Answer 2

inspect the jars , creating a packages list in libs you are using.

Then try adding following for those packages in the list in your proguard config file:

-dontwarn org.codehaus.jackson.**

...

-keep        class org.codehaus.jackson.** { *; }
