You are not building with the --prod flag most likely.

actually I’m building with ionic build android --prod --aot --fulloptimize

here is my situation:

After upgrading to latest Ionic & Cordova , my RC4 project build failed , I got “Error(errors.unsupportedEnvironment());” , however I decide to create full new project and copy pages,provider, etc. form RC4 version. Everything works fine in browser, but when I was try to build I got msg that I need to update android SDK to version to 25 and JAVA JDK to 1.8, so I did it.

Previous RC4 builds was working with android 23 and java jdk 1.7 !?

Now build works fine but APK is much bigger.

Can I get back somehow to old SDK & JDK ? Setting environment variables doesn’t help.
