I test both of the tools in the Activitydiary (https://github.com/ramack/ActivityDiary), but they got great differences under same test sequences. I got about 50% instruction coverage from Jacoco but only 16% by ACVTool. I know they work in different conditions but i wonder why there is a huge gap here.

JaCoCo only counts coverage for the present Java code developed by you. ACVTool measures the whole APK codebase including the libraries that you usually add as dependencies in your app/build.gradle

Thank you for explanation!
