How to set up an environment for creating apk through ionic?

Question

Angular

Good evening, I just can’t set up the environment for creating an apk file, I built my application on ionic, but I just can’t build it.
I can't get into java_home
ANDROID_HOME=/opt/android-sdk
JAVA_HOME=/opt/jdk/jdk1.8.0_71/bin/java
Subproject Path: CordovaLib
ERROR: JAVA_HOME is set to an invalid directory: /opt/jdk/jdk1. 8.0_71/bin/java
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
