I solved this problem by changing the Android SDK Build-tools from version 24 to version 23.0.3

In Android Studio I uninstalled Android SDK Build-tools version 24, installed version 23.0.3 and then tried to build the android project with the ionic CLI, and it worked.

I am using jdk1.7.0_79

Thank you

@priteshpmehta Thanks.

Thanks a lot!, worked for me too, using jdk1.7.0_45. I hope someone (at Ionic ?) notices this problem because there can be a conflicting requirement to use the latest Android SDK Build-tools in Android Studio.

Yes, same here. Unistalled SDK Build Tools 24.0.1 and it works again!

Thanks,

RGecy

Salvou o dia! Obrigado.

Thanks, this helped me too!!

Thanks a lot! It works for me too! I’m using jdk jdk1.7.0_09.

This also worked for me. Thanks!

You saved my day, THANKS A LOT @priteshpmehta

this solves the problem. thanks for the help

It worked for me too. I deleted the version 24 Android SDK Build tools using Android SDK manager and then I could do ionic build android without errors.

Thanks a lot!!! It solved my problem.

THANK YOU! This problem was driving me crazy.

“Another separate issue is that versions 24 and higher of the Android SDK Build-tools package require Java JDK 8 or higher.” So yeah it would not run with java 7 :slight_smile:

Great! works… thank you so much!

It works for me too, thanks. Now the only problem is that, when I try to install the generated APK in an android phone, it says “there was an error while analysing the package”. Wonder how to solve that one now.

Thank You Pritesh … I Got same Issue … And Solved …

Why delete the v24 build? Just update the Java dev kit to 8+ from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

My default java Version was 1.7 (check withjava -version ).
But i already had 1.8 on my system, so i just had to change to $JAVA_HOME variable to make it work. No need to uninstall v24.

How to change $JAVA_HOME is described in this SO Article:
