Question by feohotl · Jan 23, 2017 at 11:42 AM · androidcompiler

How to compile App with New Android Compiler, Jack (Java Android Compiler Kit)

Hi All,

Im developing an Unity Android App which depends on a .Jar lib compiled with Java 8 (Java 7 version is not available :( ). I would get PARSE ERROR: unsupported class file version 52.0 when Unity try to produce Android Apk.

Currently Android(dex) seems to require Jack compiler for compiling Java 8. I was wondering is there a way I could tell Unity to use Jack ?

Alternatively, I knew I could export my Unity Project to Android Studio project first, and build an APK by Android Studio with JackOption = true. Its kind painful if I have to build my app every time in this way.

Is there any better solution for solving this problem? Very appreciated for your help in advance.
