Any idea to fix it?

I have this problem in the android studio in Linux OS after installing a plugin, I resolved this issue with deleted.AndroidStudio4.0 folder from Home Directory and other ways you can go to this directory and delete the last installed plugin that caused it.
Directory : /home/your system's name/.AndroidStudio4.0/config/plugins .
and for Windows
Directory : C:\Users\your system's name.AndroidStudioPreview4.0\config\plugins
Note: this directory is hidden and you must visible before use it.

Unity: Failed to build apk

So I've tried everything I could find. It keeps showing the below. I tried replacing the tool folder (C:/Users/(My user name)/AppData/Local/Android/Sdk with a lower version. I tried replacing the entire sdk. I tried uninstalling then re-installing android studios. I really don't know what else to do. Kinda disappointing that I finally finished making an original minigame but can't build it. I've been struggling with this for the past 12 hours sigh. Thanks for your time!

According to this answer it appears that...
Java 9 removed the sun/misc/BASE64Encoder class.
A workaround is to downgrade to Java 8.

I have re-installed java 7 and java 8 both . Also Reinstalled Android Studio. But still there was no help.
I had installed octave before, was that a problem?

To resolve the problem you should install JDK 64bit. From the comments, you have installed 32-bit JDK

I was having the same issue. I killed the app and reopened. It fixed the issue for me.

when installing Android Studio in ubuntu 15,run studio.sh,but it report "cannot open shared object file"

I install an Android develop environment in ubuntu15,after installing JDK,and SDK tools,run studio.sh,it reports some error info:

How can i fix it? o.0

You seem to have installed the 32 bit version of the java SDK as indicated by this line:
/home/xhk/java/jdk1.8.0_60/jre/lib/i386/libawt_xawt.so
But your system is a 64 bit system as indicated by these lines
/usr/lib/x86_64-linux-gnu/libXtst.so.6
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0
There are two solutions. The first is to install the 64 bit version of the java jdk. The second is to install the 32 bit version of the libXtst
sudo apt-get install libxtst6:i386
I would prefer the first option

How can I resolve this? I'm using Ubuntu 14.0.4

I am using Intellij in Ubuntu too with no errors.
It's hard to say what is happening just by the information provided but I would suggest you to:
1 - Update your Ubuntu with the latest packages
2 - Download the latest version of the IDE, unpack it and try again
