Android Build error (gradle)


I am developing an Ionic 2 app on MacOS Sierra.

I’ve completed in-browser testing but am getting an error when executing ‘ionic build android --release --prod’:

FAILURE: Build failed with an exception.

  • Where:
    Build file ‘/Users/davidebbitt/Desktop/ionic2/cholTracker2/platforms/android/build.gradle’ line: 20

  • What went wrong:
    A problem occurred evaluating root project ‘android’.

java.lang.UnsupportedClassVersionError: com/android/build/gradle/AppPlugin : Unsupported major.minor version 52.0

The reference line 20 in the gradle file is:

apply plugin: ‘’

I am longing to get this app into the Play store, so any help will be greatly appreciated.



Looks like you are building with an old JDK. You need to have your Java environment set up to build with Java 8.


you need to set the JAVA_HOME = /usr/lib/jvm/java-8-oracle


where do we have to set this above path


which OperatingSystem you are working on? If its on ubuntu then open a terminal, move to the project(your ionic2 project) folder and then set that JAVA_HOME variable


I have ionic 3 and I am on ubuntu
In .profile file I have set export JAVA_HOME=$JAVA_HOME:/usr/lib/jvm/java-8-oracle
ionic cordova build android is working fine
but ionic cordova run android is throwing the below error

Total time: 1.323 secs
Built the following apk(s):

No target specified and no devices found, deploying to emulator

  1. Download desired System Image by running: /opt/android-sdk/tools/android sdk

You may get more insight by running the Cordova command above directly.
