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.

How to resolve the auto build failure error?

So, whenever I open Android Studio, it shows me an error in the Problems Tool Window:

Please help me to resolve this error.
Thanks for everybody who helps me.
I have updated all my plugins and Android Studio to the latest version.
I have also tried uninstalling and reinstalling android studio.
Edit:- Changing the compiler to eclipse doesn’t work for me.

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.

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
