I’m currently trying to build an android application using the Android 4.1.2 Java libraries.
Unfortunately, I want to use a newer version of the org.json package, which appears in that library.
Am I able to tell Eclipse not to use the org.json package in the Android 4.1.2 Jar?
It sounds like you are encountering a Java package name collision. Unfortunately as the code in Android comes pre-packaged, your best bet is to rename the newer json package and use that to avoid using the prebuilt one.
