I import iosched into my android-studio,and to learn how to remove unused code from jars.When I executing 'installDebug' there is no problem,but when I executing 'installQualityassurance', or just changed minifyEnabled's vaule to true and then executing 'installDebug' again,there will be a problem like below:

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':android:packageDebug'.

Unable to compute hash of E:\Android\android_studio_workspace\iosched\android\build\intermediates\classes-proguard\debug\classes.jar

I know the key point to remove unused code from jar is change minifyEnabled's vaule to true,but in my project ,for some jars it works,but for android-support-v4.jar has no effect. What should I do to remove unused code in android-support-v4.jar? Thanks a lot!

Use proGuard instead of removing code from android-support-v4.jar – Attaullah Apr 15 '16 at 06:24
