Install Android Studio on Ubuntu with error of "Plugin com.intellij failed to initialize and will be disabled"

Just try to install the Early Access Preview of Android Studio on Ubuntu 13.04. But error of "Plugin com.intellij failed to initialize and will be disabled:null" happen...!

It's due to IntelliJ IDEA need fixed installation of JDK, it have to be one of the following location:

• /usr/java
• /opt/java
• /usr/lib/jvm

Remark: After you installed JDK in the location, you have to set environment parameter point to the installed location. In my practice, I use the following commands in Terminal to update alternatives:

$sudo update-alternatives --install /usr/bin/javac javac /opt/java/bin/javac 1
$sudo update-alternatives --install /usr/bin/java java /opt/java/bin/java 1

where /opt/java/ is the location of my installed JDK.
