Proguard giving "Warning: org.msgpack.*"

Question

Using Eclipse to export my project, I get the following warnings:

Some third party things I am using are mixpanel.com, parse.com, ActionBarSherlock (http://actionbarsherlock.com/), and TestFlightApp.com.

I did try to put in the following into my proguard-myproject.txt:

-dontwarn javassist.**
-dontwarn javax.tools.**
-dontwarn json.simple.parser.**

However, if I put those in my app crashes immediately after I launch the app, so I am guessing I need to clean up the warnings by including libraries properly.

Question:

I was wondering what I needed to include in my proguard-myproject.txt file to get rid of these warnings and be able to launch my app on my phone without it crashing immediately after I launch the app. If I run the app from eclipse in just the normal Run.. or Debug option, the app works fine so I am guessing somehow Proguard is removing some classes I need.

I do also have the dump.txt, mapping.txt, seeds.txt, and usage.txt if anyone needs to see them, but they are fairly long so I thought no need to paste here for now.

Solved!

thanks to @Eric Lafortune and looking proguard documentation

Main problem was just adding this:

-keep class com.myapp.** { *; }
-keep interface com.myapp.** { *; }

where com.myapp.** is the package for my app

The Ant/Eclipse/Gradle build processes in the Android SDK automatically specify input jars, library jars, and output jars for you, so you mustn't specify them again in the configuration. This is why you are getting lots of warnings about duplicate classes.

On the other hand, some org.msgpack classes depend on classes that are not in your libs directory. If your debug build works fine, you can tell ProGuard to ignore it with:

-dontwarn org.msgpack.**

If your application crashes, you should look at the logcat output. You can find suggestions in the Troubleshooting section of the ProGuard manual.
