Error: spawn EACCES when trying to build Ionic app in Ubuntu 15.10

Question

I was was working with an cordova/ionic project for past couple of weeks. I used windows for development. But recently I had to change my developing environment to Ubuntu. I use Ubuntu 15.10. Tried to build the same project in Ubuntu after setting up Android SDK , JDK ANT ect., gave me this error. I can "ionic serve" or "cordova serve" without any problem. Tried removing and re adding the platform android but the issue was same. Below is the error.

user@myhost:~/works/myproject$ ionic build android

Checked for permission/ownership issues but didn't find any. I can compile a java file therefore not a problem with my jdk. Here is my ionic info

Cordova CLI: 5.4.0
Ionic CLI Version: 1.7.8
Ionic App Lib Version: 0.6.4
OS: Distributor ID: Ubuntu Description: Ubuntu 15.10 
Node Version: v4.2.2

Having a chmod 765 recursively on my android-sdk folder fixed it

Thanks to Muhsin for Help :D

chmod 777 -R ~/android
