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:

It's complaining about libraries that were used in my project. My settings are below:

buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        proguardFile file('proguard-rules.txt')
        signingConfig signingConfigs.release
    }
}

Within my proguard-rules.txt I have the following:

-libraryjars libs

All of my libraries are stored in the libs folder. Is there anything else i'm doing wrong?

Answer 1

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.** { *; }

Answer 2

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.
