Answer 1

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 eg JAVA_HOME C:\\Program Files\\Java\\jdk1.8.0_172

Answer 2

对我来说，解决方案是安装 1.8 然后不命名环境路径“...\\Java\\jdk1.8.0_161\\bin”而是“...\\Java\\jdk1.8.0_161”

Answer 3

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
