Answer 1

put the other versions of JDK in a other folder and:

sudo -s

apt-get install gradle

ionic 2 - Error Could not find an installed version of Gradle either in Android Studio

Answer 2

unstall any java sdk you have Install JDK 1.8 follow this link
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and then look for Java SE Development Kit 8u172 and accept aggreement then download it. and then change your enviroment variable to match the java sdk location e.g JAVA_HOME C:\Program Files\Java\jdk1.8.0_172

Answer 3

For me, the solution was install 1.8 then not naming environment path "...\Java\jdk1.8.0_161\bin" but "...\Java\jdk1.8.0_161"
