Follow this steps

1. Run ionic cordova build --release android

Answer 3

The Path as mentioned before is the correct path to find your generated apk file.

yourProject/platforms/android/build/outputs/apk/android-rele‌​ase-unsigned.apk

Please check these steps if there something missing.

I. Development environment dependencies

1)You need at Least to download a java JDK 8

2)Download an Android SDK manager

3)you must Add them to the environment variables

(Windows)

i)Open environment variables

ii)ANDROID_HOME:create a new user variable with name ANDROID_HOME and add the path of the SDK manager ex.C:\\xxx\\Android\\sdk

iii)edit the user variable PATH value and add to it platform tools path ex. C:\\xxx\\Android\\sdk\\platform-tools

iV)JAVA_HOME:Don't forget also to edit in the user variable PATH, your old JAVA_HOME env path with the new JDK Path . ex.C:\\Program Files\\Java\\jdk1.8.0_144

4)Globally install ionic and cordova

npm install -g ionic cordova

II. Ionic CLI for build android

5) ionic cordova platform add android

6) ionic cordova build android

NB: there sometimes logging in issue through CLI when using this command, the next steps doesn't really make sense but it worked for me.

ionic config set backend pro -g

Retry the build process again ,if Still there a problem change to legacy and Then again back to pro

ionic config set backend legacy -g

ionic config set backend pro -g

It should work now, retry the build process again.

If still there a problem then make an app through the website of ionic use this command with the --pro-id of your app and retry again.

ionic start --pro-id <ID>
