Hi All,
I’m new to ionic and I need some help from you.
I’m learning ionic through one of the YouTube tutorial. I followed the below steps and no issues.
- npm install -g cordova ionic
- ionic start myApp sidemenu
- ionic serve --lab
everything working proper until here. But,when I run the build android code it gives errors. I don’t know how to solve it. I search and read many forums. But, can’t get exact solution because, each one says different solution and I got confused. I kindly request you to please help and guide me to solve this.
I installed Android studio 2.1.1
My ionic version is
Cordova CLI: 6.3.1
Ionic Framework Version: 1.3.1
Ionic CLI Version: 2.0.0
Ionic App Lib Version: 2.0.0-beta.20
OS: Windows 7 SP1
Node Version: v4.5.0
In Node.js command prompt,
after added platform android I followed these steps
step1: c:\users\myname\newApp\platforms\android\ionic android --release
step2: c:\users\myname\newApp\platforms\android\cd…
step3: c:\users\myname\newApp\platforms\cd…
step4: c:\users\myname\newApp\ionic build android --release
The errors are:
