那是因为没有设置JAVA_HOME。如果没有设置的话需要设置JAVA_HOME.
如果你用的是Ubuntu环境的话，JAVA_HOME的设置如下：
在文件/etc/profile中，
export JAVA_HOME=/usr/local/lib/jdk1.8.0_102
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:$PATH
还有在AndroidStudio中，查看File--Project Structure--SDK location--JDK location,看JDK location是不是正确设置了。
