Unable to build android with vanilla project

ionic-v1
1

I have tried to execute the simple “Get Started” tutorial, without edit any file, but simply using this command

$ npm install -g cordova ionic
$ ionic start test tabs
$ ionic platform add android

And all these 3 command work file. After i have run this

$ ionic build android

And the command fails with errors

I have NOT changed any into the vanilla project; i have an Android Studio with SDK API level 22, 23 and 24 enabled.

The $ java version show

java version “1.7.0_79”
Java™ SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot™ 64-Bit Server VM (build 24.79-b02, mixed mode)

What is broken? this is my first attempt with IONIC and Android :frowning:
Thank you in advance

Same problem here. Is there a preferred version of JDK to use with ionic? already tried 7.0_79 and _80 (both x86 and x64), they all failed. Just to be clear, I altered JAVA_HOME in every trial.

The error occurs with the plain examples from ionic (blank, sidemenu and tabs):

“Execution failed for task ‘:transformClassesWithDexForDebug’.”

I tried adding " multiDexEnabled true" to my build.gradle, turns out the error is only delayed to arise with: “transformClassesWithMultidexListForDebug”.

It is probably the Java version. Turns out ionic getting started page directs you to the Android platform installation process, which referes to an old version of java (java 7). JDK 8 can be downloaded from here:

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

I will test it when I get home, but that is most likely the reason.
