Cannot install rJava on Ubuntu 16.04

[GanjinZero]

When install rJava by

install.packages('rJava')

It shows:
...
checking whether Java run-time works... yes
checking whether -Xrs is supported... yes
checking whether -Xrs will be used... yes
checking whether JNI programs can be compiled... configure: error: Cannot compile a simple JNI program. See config.log for details.

I have tried

R CMD javareconf

It shows:

So how can I fix my problem? This R is installed by Anaconda3.

See the warning above JAVA_HOME is not a valid path, ignoring - make sure you unset JAVA_HOME as it's wrong. Run R CMD javareconf and the install rJava. If you still see issues, check config.log in the rJava directory for details.
